Exploring the challenges and risks of dead body handling faced by healthcare professionals during the coronavirus pandemic: Cross sectional survey study

The coronavirus pandemic shocked the already overwhelmed global healthcare system, challenging its preparedness to deal with mass fatalities. Our research examines the safety issues faced by healthcare workers when handling dead (deceased) bodies, highlighting the need for better strategies in the event of mass fatalities. Healthcare providers involved in dead body handling during the COVID-19 pandemic in the U.S. were eligible to participate in our study. Using a web-based survey, we analyzed responses of 206 participants across 43 U.S. states. We used the Systems Engineering Initiative for Patient Safety (SEIPS) framework to deduce themes from participants' open-ended responses. The study showed how routine tasks become extraordinarily challenging during pandemic due to increased workload, emotional stress, and resource constraints. Tasks such as lifting and transferring bodies, underscored physical and emotional toll on workers. The mental strain induced by mass fatalities and the complexities of communicating with families and peers were also prominent, adding to the overall burden on healthcare workers. The participants emphasized the importance of specialized training, policy refinements, and improvements in its implementation. In conclusion, our study contributes to understanding the complexities of dead body handling during a pandemic. It underscores the need for emergency response planning and systemic changes in healthcare policies and practices to ensure the safety and well-being of healthcare workers engaged in these critical tasks.

Problems of operation of positive pressure ventilators on the basis of surveys of Polish officers of the State Fire Service

Positive pressure ventilators (PPV) used by 97.7% of officers of the National Fire Service in Poland, are characterized by work that is not in line with the expectations of the firefighters. In order to improve the technical and operational features of these devices, a survey was conducted among 25,000 eligible firefighters, identifying the application of these devices, problems in use and expected development directions. A total of 682 officers voluntarily completed the survey. Based on their findings, it was determined that ventilators are most often used to smoke out buildings after or during a fire. Mentioned problems when using these devices were mainly noise (78.2%), exhaust emissions (68.5%), and impediments to mobility through the device's relatively heavy weight (40.2%). Other inconveniences were mentioned by less than 20% of firefighters. Polish firefighters expect the development of these devices mainly in terms of the above-mentioned features (noise reduction (81.7%) and reduction of the weight and size of the ventilators (about 50%)). Other expectations relate to the improvement of smoke removal in buildings: increasing the efficiency of smoke removal (46.4%) and efficiency regarding the rate of smoke removal in a building by increasing the size of the incoming airflow from the building's surroundings (33.2%). About 15% of firefighters expect changes in the operation of the ventilator itself, that is, an increase in the effective operating time (electric ventilators) and an increase in the device's uptime. The aim of the article is to identify the issues encountered during the operation and to indicate the expected direction of development for PPV by users. This information can be used by engineers to initiate new development work on these devices.

Aspects of occupational safety: a survey among European cancer nurses

PURPOSE

Nurses are particularly at risk for occupational exposure to hazardous cancer drugs, risking both acute and chronic health effects. Knowledge on the implemented safety precautions into minimizing these risks is limited.

METHODS

The European Cancer Nursing Index (ECNI) was developed by the European Oncology Nursing Society (EONS) to illustrate the development and status of this profession. In this study, anonymous online survey data on occupational safety reported by European cancer nurses as part of the ECNI 2022, was analysed.

RESULTS

A total of 630 cancer nurses from 29 countries responded to the survey. A majority reported that written guidelines (n = 553, 88%) on safe handling and administration of hazardous drugs, personal protection equipment (PPE) and cytotoxic spillage kits (n = 514, 82%) were available at their workplaces. 130 (21%) nurses reported that wipe testing to assess any residual hazardous drugs on workplace surfaces were conducted systematically at their workplaces. 185 (29%) nurses reported that nurses sometimes or always continued with their regular tasks (including handling hazardous cancer drugs) during pregnancy and breast feeding. 185 (29%) also responded that nurses at their workplaces did not receive an introductory education program before handling hazardous drugs. In total, 346 (55%) of the nurses reported that their workplace had a freedom to speak-up guardian or whistle blower policy for members of staff.

CONCLUSIONS

Even if most nurses report that there are safety routines in place at their workplaces, the results reveal several serious occupational risks for European nurses handling hazardous cancer drugs. Actions are needed to improve and optimize occupational safety for nursing staff.

The structure of near misses and occupational accidents in the polish construction industry

Near misses are referred to in literature as precursors of occupational accidents. These events, and their relationships with occupational accidents in various economic sectors have been the subject of research in several countries around the world. In Poland, there has not been a lot of research with regards to near misses in the construction industry, and the published materials are of a very general nature. This article aims to fill the existing research gap regarding the relationship between near misses and occupational accidents in the Polish construction industry. The aim of the research presented in the article was to identify the qualitative and quantitative structure of hazardous events in the construction industry, and to estimate the a posteriori probability of the occurrence of such events. The research was carried out on the basis of information obtained from the hazardous event registration system from a large Polish enterprise that carried out construction works in Poland in the years 2015-2022. Identified dangerous events in the construction industry were divided into two generic groups, i.e. occupational accidents and near misses. Within each group, eight categories of hazardous events were identified, and subcategories were defined within each category. The power of each set and subset of events was then calculated. The posterior probability of the occurrence of events classified into individual sets was estimated using Bayes' theorem. Cross-validation of the obtained results was performed. Conclusions resulting from the conducted analyzes were formulated. The most common category of the analyzed dangerous events in the construction industry is "being hit by objects"; "being run over/falling over" and "work environment". Knowledge of the most common causes of near misses will allow actions that aim to reduce the number of occupational accidents to be determined.

Farm operations and slips, trips, and falls among corn farm workers in Thailand

Slips, trips, and falls (STFs) represent a main source of injury among farm workers. The purpose of this study was to evaluate the association between farm operations and STFs among corn farm workers. We conducted a cross-sectional study using a self-administered questionnaire among corn farm workers in Nan and Saraburi provinces, Thailand from July 5 to 23, 2022. Poisson regression analysis was used. Among 338 participants, 122 (36.1%) had experienced an STF in the previous 6 months. Conducting very frequent, frequent, or occasional pest management was associated with a higher incidence rate ratio (IRR) of STFs than never or rarely pest management (adjusted IRR 1.93, 95% confidence interval [CI]=1.23 to 3.04, p=0.004). People with marginal or unsatisfactory work break lengths had a higher incidence rate of STFs than those with satisfactory work breaks (adjusted IRR 1.40, 95% CI=1.03 to 1.89, p=0.030). We found that corn farm workers in our study often experienced STFs, which was associated with a high frequency of pest management practices and inadequate work breaks. Reducing the physical burden of pest management may be effective as an STF prevention strategy.

Climate projections of human thermal comfort for indoor workplaces

Climate models predict meteorological variables for outdoor spaces. Nevertheless, most people work indoors and are affected by heat indoors. We present an approach to transfer climate projections from outdoors to climate projections of indoor air temperature (Ti) and thermal comfort based on a combination of indoor sensors, artificial neural networks (ANNs), and 22 regional climate projections. Human thermal comfort and Ti measured by indoor sensors at 90 different workplaces in the Upper Rhine Valley were used as training data for ANN models predicting indoor conditions as a function of outdoor weather. Workplace-specific climate projections were modeled for the time period 2070-2099 and compared to the historical period 1970-1999 using the same ANNs, but ERA5-Land reanalysis data as input. It is shown that heat stress indoors will increase in intensity, frequency, and duration at almost all investigated workplaces. The rate of increase depends on building and room properties, the workplace purpose, and the representative concentration pathway (RCP2.6, RCP4.5, or RCP8.5). The projected increase of the mean air temperature in the summer (JJA) outdoors, by + 1.6 to + 5.1 K for the different RCPs, is higher than the increase in Ti at all 90 workplaces, which experience on average an increase of + 0.8 to + 2.5 K. The overall frequency of heat stress is higher at most workplaces than outdoors for the historical and the future period. The projected hours of indoor heat stress will increase on average by + 379 h, + 654 h, and + 1209 h under RCP2.6, RCP4.5, and RCP8.5, respectively.

[Climate change and type I allergies at the workplace]

The consequences of climate change, the increasing frequency, duration and intensity of extreme events such as excessive drought, heat waves, large-scale forest fires, heavy rainfall and associated flooding also affect workers' conditions in the workplace in many ways. Allergic diseases of the respiratory tract and skin due to workplace exposure can also arise or be influenced by direct and indirect consequences of climate change. This affects outdoor workers not only through increased exposure to pollen allergens, but also through climate-related increases in typical workplace allergens. As an indirect effect of climate change, manufacturing processes and exposure at workplaces are changing, which can also cause new sensitization and allergies. Lifestyle changes, which are primarily intended to contribute to climate protection and sustainability, can also lead to new or changed products and thus to changed manufacturing processes and exposures in the workplace, so this should also be considered an indirect effect of climate change on the health of workers. The emergence of new occupational sources of sensitization due to new or changed allergen exposures must be considered in the context of occupational health and safety and requires proactive measures to protect workers.

Robotization of Industrial Processes: Motivational Differences between Companies with and without Existing Robotic Processes

OCCUPATIONAL APPLICATIONSOur survey of 100 manufacturing facilities revealed statistically significant differences among company types in their perceptions of cost savings, productivity gains, and safety improvements as benefits of robotic implementation. Regardless of company type or size, indications of presence of cumulative, incidental, and static postural hazards were identified as primary perceived factors for injury potential. More than half of the surveyed companies reported being unaware of general safety standards utilized within their facilities, and most (70%) robotic companies were unaware of any robotic-specific standards utilized at their company. Our results indicate the importance of accounting for varying perspectives between company types regarding motivation for and safety impacts of robotics. With the advancement of technology and robotization of the manufacturing industry, there are also pressing needs for advancing robotic safety standards, implementing training programs, and continuous promotion of the general safety awareness.

Impact of nasal photodisinfection on SARS-CoV-2 infection in an industrial workplace

Objectives

We aimed to evaluate a quality improvement initiative designed to control SARS-CoV-2 (COVID) using the large-scale deployment of antimicrobial photodisinfection therapy (aPDT) for nasal decolonization in a Canadian industrial workplace (a food processing plant).

Study design

Using a retrospective chart review of treatment questionnaires, linked to COVID laboratory testing results, a quality improvement assessment was analyzed to determine treatment effectiveness and safety.

Methods

This voluntary aPDT intervention involved the administration of a light-sensitive liquid to the nose followed by nonthermal red-light irradiation on a weekly basis. Employees in food processing industries are at increased risk for COVID infection due to the nature of their work environments. In an effort to mitigate the transmission and consequences of the disease among such workers and the community at large, aPDT was added to a well-established bundle of pre-existing pandemic safety measures (e.g., mask-wearing, testing, contact tracing, workplace-engineered barriers, increased paid sick leave).

Results

From December 2020 to May 2021, we found high interest in and compliance with aPDT treatment, along with a statistically significant lower PCR test positivity rate in the study population in comparison to the case rates for the local Canadian province. Treatment safety monitoring and outcomes of the aPDT program demonstrated no serious adverse events.

Conclusions

This study suggests nasal photodisinfection provides safe and effective COVID viral suppression when deployed across the majority of workers in an industrial workplace setting.

Preventing fatal accidents in construction through the management of barriers

The research presented in this article addresses the construction industry's need for a real-time safety performance indicator for use in managing the risk of fatal accidents. It involves the development and testing of an indicator of the availability of barriers against fatal accidents when carrying out construction work. In designing the indicator, knowledge and experience from different fields have been utilized including classic barrier theory, barrier management in major-accident hazard industries, quality management, and safety performance measurement in construction. The main aim of the research has been to evaluate the barrier indicator in practical use. The evaluation is based on results from field tests of the barrier indicator at two construction sites and on data from fatal accidents in the construction industry. It provided support for the assumption in the design of the barrier indicator that a few types of hazards dominate the statistics of fatal accidents. The field tests demonstrated the usefulness of the barrier indicator, both in checking the status of the barriers in individual construction activities and in measuring the overall standard of barriers against fatal accidents on the construction site. The possibilities and limitations of the method are discussed based on general criteria for assessing safety performance indicators. Another aim has been to use the experiences from the field tests as input to the design of a method for barrier management through the phases of a construction project. This work resulted in a model that integrates the barrier indicator and underlying methods and tools into a barrier management system. There is significant potential for effective barrier management by integrating the indicator and associated methods and tools into the management systems in the construction industry utilizing digital technology.

Safety of Magnetic Resonance Imaging in Pregnancy

Magnetic resonance imaging is being increasingly used to diagnose and follow up a variety of medical conditions in pregnancy, both for maternal and fetal indications. However, limited data regarding its safe use in pregnancy may be a source of anxiety and avoidance for both patients and their healthcare providers. In this review, we critically discuss the main safety concerns of Magnetic Resonance Imaging (MRI) in pregnancy including energy deposition, acoustic noise, and use of contrast agents, supported by data from animal and human studies. Use of maternal sedatives and concerns related to occupational exposure in pregnant personnel are also addressed. Exposure to gadolinium-based contrast agents and sedation for MRI during pregnancy should be avoided whenever feasible.

Vision Zero for industrial workplace safety innovative model development for metal manufacturing industry

This study target is to investigate Vision Zero strategy & develop a model that contributes to the reduction of injuries, accidents, and fatalities. In turn, this model aims to enhance the well-being, safety, and productivity of the manufacturing sector. The study has conducted comprehensive theoretical reviews from reputable journals that are relevant to Vision Zero, manufacturing industries in general, and specifically the metal manufacturing industries. The study also underwent a validation of the Vision Zero strategy model by discussing with a selected professional team in this field from the industry. The results of this study shows that research related to the Vision Zero strategy has not been widely disseminated or popularized. It further reveals that manufacturing industries predominantly operate based on traditional work environmental principles, rather than actively embracing the concepts and principles of Vision Zero. The study has also uncovered that previous research on Vision Zero primarily focused on road accidents, injuries, and fatalities. In contrast, studies conducted in the manufacturing sector primarily examined aspects related to safety, health, and worker well-being. However, these studies often failed to sufficiently align their objectives with the overarching priority of enhancing productivity, especially within the context of the industrial revolution. Due to the limited studies related to Vision Zero and a new area for the research database, setting comparative goals and developing a stringent strategy may not be the final outcome here with the developed model. The results of this research could provide valuable insights to policymakers & lawmakers in order to enhance workplace health and safety regulations which support industries' productivity. This study represents a pioneering effort in developing a new Vision Zero strategy model that aligns with productivity goals and emphasizes knowledge-based approaches for reducing or eliminating injuries, accidents, and fatalities.

[Emergency care as a high-risk workplace-Measures to deal with violence against employees]

BACKGROUND

Many employees in the field of emergency care experience verbal and physical violence caused by patients or visitors. The aim of this project is to gain insights into which measures are available to deal with violence in emergency care and how employees subjectively evaluate them.

METHODS

A nationwide cross-sectional online survey was conducted in 2020. The questionnaire contained items on violence prevention, intervention, and follow-up measures. Quantitative data were analysed descriptively and free text data according to Mayring's qualitative content analysis.

RESULTS

A total of 349 respondents, including 115 supervisors participated in the survey. The availability of security staff and standardised reporting of incidents were considered important measures for dealing with violence. Of the managers, 67% reported not having a security service, while 56% claimed that reported incidents of violence were not dealt with in a structured way. A high workload in emergency care can impede the implementation of measures. Overall, the demand for increased support by supervisors and the hospital management became clear.

CONCLUSION

It is evident that employees consider certain measures to be effective; however, these measures are often not consistently implemented. There is a need for structured reporting of violent incidents against employees to facilitate a realistic recording of the prevalence. In addition to increasing the (nursing) staff, restricting access for visitors can decrease the conflict potential.

Radiographers' organisational commitment and occupational stress: First Covid-19 wave

INTRODUCTION

Radiographers, like many health professionals, are in a high-risk group for succumbing to workplace demands beyond their ability to cope, particularly in the context of the COVID-19 pandemic resulting in occupational stress. Occupational stress has been linked to poor organisational commitment. Therefore, the purpose of this research was to evaluate radiographers' organisational commitment and occupational stress after the first wave of the COVID-19 pandemic.

METHODS

A mixed method approach entailed data collected from purposively sampled Australian radiographers working during the first COVID-19 wave. The quantitative phase used an online commitment questionnaire, and 21 semi-structured individual virtual interviews were conducted in the qualitative phase. Data interpretation and analysis used statistical and thematic approaches.

RESULTS

The quantitative data revealed a higher level of continuance than affective and normative commitment. Whereas the qualitative findings showed participants high levels of affective commitment to their occupation and, together with leadership support, working collectively towards a positive outcome.

CONCLUSION

Despite the variety of occupational stressors that arose during the COVID-19 crisis, Australian radiographers enjoy a high level of occupational and organisational commitment.

IMPLICATIONS FOR PRACTICE

Radiographers' organisational commitment represents their emotional and psychological attachment to their workplace, and radiographers experiencing occupational stress represent high levels of psychosomatic distress and burnout. Therefore, considering radiographers' organisational commitment and occupational stress is essential in the delivery of services, quality of patient care and radiographers well-being.

Exploring factors associated with paramedic work-related psychological injury through data linkage

INTRODUCTION

In comparison to the general population and other emergency services workers, paramedics experience high rates of work-related psychological injury. However, there is limited understanding of the case and practitioner-related factors that increase the risk of psychological injury among these workers. This paper aims to identify case and practitioner-related factors associated with paramedic work-related psychological injury in Victoria, Australia, through data linkage.

METHODS

Data linkage of 7,223 paramedic injury reports with electronic patient care records, and paramedic demographic data from the single state-wide ambulance service in Victoria, Australia - Ambulance Victoria. Injuries reported between 1 January 2015 and 30 June 2020 were included. Factors associated with paramedic psychological injury were assessed using multivariable logistic regression analysis.

RESULTS

A total of 4,641 (64%) injury reports were successfully linked, of which, 244 (5%) were psychological injuries. Shift hours between 0401 and 0800 (AOR 1.83; 95%CI: 1.12-2.97), cardiac arrest or deceased patient attendances (AOR 2.15; 95%CI: 1.06-4.34), hospital or medical center case locations (AOR 2.44; 95%CI: 1.22-4.91), and Priority 0 (AOR 2.27; 95%CI: 1.26-4.09), Priority 2 (AOR 1.56; 95%CI: 1.04-2.33), and Priority 3 (AOR 1.95; 95%CI: 1.15-3.32) dispatch codes were associated with increased odds of psychological injury. Increasing patient age (AOR 0.98; 95%CI: 0.97-0.99), and the absence of other emergency services on scene (AOR 0.50; 95%CI: 0.34-0.72) were associated with decreased odds of paramedic psychological injury.

CONCLUSIONS

This is the first study to collectively examine and identify EMS case and practitioner-related characteristics associated with paramedic psychological injury through data linkage of EMS agency-level data sources.

PRACTICAL APPLICATION

The findings of this study highlight the dispatch case characteristics that may increase the risk of a paramedic sustaining a work-related psychological injury, and consequently facilitate the early identification, intervention, and support of the individuals most at risk.

Statistical analysis of the severity of occupational accidents in the mining sector

INTRODUCTION

The aim of this paper is to understand the causes of occupational accidents in Spain's mining sector in order to propose action plans and improve future accident rates.

METHOD

This research analyzed a pool of data on 15,032 accidents occurring in the mining sector and reported to authorities between 2013 and 2018. Accidents are divided into three levels of severity: light, serious, and fatal. We study the influence of 12 variables on the accident severity rate in our sample.

RESULTS

The results show that accident severity is related to age, gender, nationality, length of service, economic activity, company size, accident location, days of injury leave, day of the week, deviation, injury, and specific Spanish region. This sector produces a high rate of serious accidents compared to all other sectors; has a male-dominated, older and experienced workforce; and employs mainly Spanish workers. Its activity is concentrated in larger companies and the work involves the use of heavy machinery and dangerous materials. We offer conclusions and future lines of research to help regulators, companies and workers to improve worker safety.

Occupational Health and Safety in the Turkish Fisheries and Aquaculture; a Statistical Evaluation on a Neglected Industry

Background

Fisheries and aquaculture are statistically acknowledged to be among the most dangerous occupations. Yet, industrial safety and health precautions against occupational accidents within the sector are not sufficiently implemented in many parts of the world. The present study aims to provide a quantified overview of work accident statistics in the Turkish fisheries and aquaculture industry.

Methods

This article presents an overview of reported injuries and fatalities in the Turkish fisheries and aquaculture industries from 2006 to 2020. Incident, permanent incapacity, and fatality rates were calculated, and the difference between fisheries and aquaculture was statistically examined.

Results

The overall incident, permanent incapacity, and fatality rates were 449.4, 4.7, and 5.7 per 100,000 worker years, respectively, over the 15-year period. With these fatality rates, fisheries and aquaculture are two of the industries with the highest fatality rates among comparable industries in Turkey. Incident rates in fisheries and aquaculture indicated that aquaculture work is more dangerous and risky. The data set includes 25 fatalities and 22 permanent incapacity cases over 15 years and shows an increase in fatality rates and occupational accidents in the last 8 years.

Conclusion

present study showed that the quality of data and reporting in the Turkish fisheries and aquaculture industries including occupational illnesses, must be improved in order to be more preventative and to develop efficient safety management in the sector. Incentives for providing thorough data on occupational incidents must be enhanced to improve occupational safety awareness in Turkish fisheries and aquaculture.

Burden of injury due to occupational accidents and its spatiotemporal trend at the national and subnational levels in Iran, 2011-2018

PURPOSE

The spatiotemporal trend of the burden of injury due to occupational accidents in Iran, 2011-2018 were assessed at the national and subnational levels.

METHODS

The burden of occupational injury was estimated using three datasets of occupational injury data, the employed population, and duration and disability weight of injuries.

RESULTS

The disability-adjusted life years (DALYs), deaths, DALY rate, and death rate (per 100,000 workers) of occupational injury in Iran drastically decreased from 169,523, 2,280, 827, and 11 in 2011 to 86,235, 1,151, 362, and 5 in 2018, respectively. The DALY rates of occupational injury were significantly different by gender and age in a manner that the DALY rate of men was much higher than that of women and the DALY rates by age group in 2018 ranged from 98 for 50 y and over to 901 for 15-19 y. The shares of injury outcomes in the total DALYs in 2018 were as follows: 63.6% for fatal injuries, 17.4% for fracture, 7.9% for open wound, 7.3% for amputation, and 3.8% for other injuries. Over 83% of the DALYs was observed in three economic activity groups of construction, manufacturing, and community, social, and personal service activities. The three provinces with the highest DALY rates in 2018 were Markazi, West Azarbaijan, and East Azarbaijan, respectively.

CONCLUSION

Despite the decreasing temporal trend, the burden of occupational injury in Iran in 2018 was high. The high-risk groups and hot spot provinces should be taken into more consideration for further reduction of the injury burden.

Does occupational injury research illuminate or obscure occupational safety?

INTRODUCTION

The effectiveness of occupational injury research may, at least in part, depend upon the perspective used in that research.

METHOD

This paper presents two perspectives occupational injury research may adopt - the injury-focused and the occupation-focused perspectives. The injury-focused perspective sees injuries as the primary unit of analysis in occupational injury research. It is based on several premises that focus its research on understanding occupational injuries. However, this focus may obscure certain factors of how injuries occur and, ultimately, how to create occupational safety. By contrast, the occupation-focused perspective sees work as the primary unit of analysis of occupational injury research. This perspective may allow researchers to solve what is described in this paper as the 'dark safety' problem (i.e., how even unsafe systems go long periods of time without failure). The paper does not argue that one or the other perspective should be the only perspective. However, a balanced perspective between injury-focused and occupation-focused research is needed to further occupational injury research.

Effect of on-site first aid for industrial injuries on healthcare utilization after medical treatment: a 4-year retrospective longitudinal study

BACKGROUND

The number of industrially injured workers (IIW) is increasing in Korea. However, little research has been conducted on whether first aid is performed at industrial sites or on the association between first aid for industrial injuries and the prognosis of IIW, including healthcare utilization.

METHODS

A total of 3,092 participants (2,562 males and 530 females) were analyzed during the 4-year study period, which contributed to 11,167 observations. Healthcare utilization was evaluated based on the number of outpatient visits, hospitalizations, and duration of hospitalization using a generalized estimating equation Poisson regression. Several time-varying socioeconomic characteristics and information about the injury were adjusted, and transfer time to the medical institutions was also considered.

RESULTS

During 4-year after the termination of medical treatment, participants who had not receive first aid visited outpatient clinics 15.243 times per year, and those who had visited 13.928 times per year, which is 16.16% less (adjusted relative risk [aRR]: 0.838, 95% CI = 0.740-0.950). Participants who had received on-site first aid with less than a 0.5-hour transfer time to the medical institutions visited outpatient clinics 14.87% less per year than those who had not received first aid (aRR: 0.851, 95% CI = 0.750-0.966).

CONCLUSION

To reduce the long-term outpatient utilization rate for IIW after medical treatment, on-site first aid must be provided in a timely manner. Employee education and first aid training are also necessary.

Health risks of titanium dioxide (TiO2) dust exposure in occupational settings - A scoping review

Titanium dioxide (TiO₂) is an inorganic compound with many applications, for example in paint, sunscreen or as food coloring. There have been concerns regarding its safety and according to IARC, the existing evidence is not substantial enough to rule them out, leading to the substance being classified as possibly carcinogenic to humans (2B). This work aims to provide a comprehensible overview about epidemiological studies on occupational health risks and methodological aspects. A literature search was conducted in two databases (MEDLINE and Web of Science). The search focused on occupational exposure since this setting provides the highest amounts of TiO₂ exposure. Of 443 unique search results, ten were included in this study, with publication dates ranging from 1988 to 2022. Seven of them are retrospective cohort studies and three have a case-control study design. Main outcomes of most studies were all-cause mortality and lung cancer mortality. For all-cause mortality, most cohort studies reported no association with TiO₂ exposure. For lung cancer mortality, a significantly increased risk was found in a study population from Europe. The analysis results of working cohorts from the US comparing exposed workers' mortality rates with those of the general population were unobtrusive. However, one US cohort found an elevated mortality risk for all causes and lung cancer based on a reference population of company workers unexposed to TiO₂. Case-control studies did not indicate an increased risk for cancer related to TiO₂. Recent publications partly questioned the validity of those earlier findings, claiming insufficient confounder analysis, most notably for smoking, as well as the presence of the healthy worker effect, masking a potential health risk. In conclusion, the associations between occupational TiO₂ exposure and mortality are unclear, but concerns regarding possible health risks recently re-emerged based on new analytical approaches, highlighting methodological difficulties that could have limited the inferential value of previously conducted studies.

"It is a different type of policing than in the bush": Police officers' perceptions of the differences in enforcement of the phone use while driving legislation in rural and urban areas

Mobile phone use while driving continues to be a significant road safety concern, despite the severe legal countermeasures to reduce this behaviour. Phone use while driving-related crashes have been demonstrated to be an issue in rural areas, yet research into the impact of legal sanctions on phone use while driving has primarily focussed on urban areas. Therefore, this study aimed to investigate differences in enforcement of phone use while driving between rural and urban environments as reported by police officers. In addition, to provide necessary context, this study aimed to explore how the police officers perceive differences in drivers' engagement in phone use while driving between rural and urban environments. To address these aims, a total of 26 police officers from Queensland, Australia (18 with both rural and urban experience, 6 with only rural experience and 2 with only urban experience) completed an interview. A total of seven themes were developed from the data. Several differences between rural and urban environments were identified concerning different types of phone offending behaviour, as well as different resources, management and infrastructure that can impact police enforcement. For example, it was suggested that drivers in rural areas have less reasons to use their phone while driving. Nevertheless, when this behaviour does occur, it is more challenging to enforce this law in rural compared to urban environments. The results not only provide important contextual information for phone use while driving research, but also suggest that enforcement strategies for this behaviour may need to be recontextualised to incorporate the more nuanced aspects of rural policing.

Occupational exposure to nanomaterials: A bibliometric study of publications over the last decade

Owing to the increased use of nanomaterials, the number of employees and professionals who are exposed to these chemicals is on the rise, despite the paucity of organized data on the possible dangers associated with exposure to these compounds. Multiple studies reveal that the lack of nanosafety awareness among employees and businesses is a serious problem that must be addressed. This shortage of information may result from insufficient knowledge generation or transmission. Academic publications play a significant role in producing new knowledge. This study presents a comprehensive bibliometric analysis of published research on workplace nanosafety which this bibliometric analysis aims to establish the permeability and significance of nanosafety themes from an occupational safety and health viewpoint in academia, to gain a better understanding of the knowledge generation phase in the area, and detected advantages and disadvantages of the topic. Scopus was used as the data source in this study. A total of 1170 publications were gathered and analyzed. The results indicated that the United States is a leader in several aspects of nanosafety at the workplace. The synthesis of co-citation and author-keyword phrases provided insight into determining the focal points of the current study. Analysis of meta data indicates that the number of writers is rising. Nanomaterial toxicity, risk assessment, and occupational exposure are the three hottest topics in this field, according to the result. In addition, the findings included worldwide growth rate, collaborative research fields, keywords, journals, and funding agencies. The advantages and disadvantages of the knowledge creation phase of nanosafety at the workplace were examined in the conclusion.

Enhancing Ergonomics in Pediatric Endoscopy Training and Practice

Pediatric endoscopists are at risk of work-related injuries from overuse and repetitive motions during endoscopy. Recently, there has been increasing appreciation for the importance of ergonomics education and training to help build long-term habits that prevent injury. This article reviews the epidemiology of endoscopy-related injuries in pediatric practice, describes methods for controlling exposures in the workplace, discusses key ergonomic principles that can be used to mitigate injury risk, and outlines tips for integrating education on endoscopy ergonomics during training.

Evaluation of long-term data on surface contamination by antineoplastic drugs in pharmacies

PURPOSE

The handling of antineoplastic drugs represents an occupational health risk for employees in pharmacies. To minimize exposure and to evaluate cleaning efficacy, wipe sampling was used to analyze antineoplastic drugs on surfaces. In 2009, guidance values were suggested to facilitate the interpretation of results, leading to a decrease in surface contamination. The goal of this follow-up was to evaluate the time trend of surface contamination, to identify critical antineoplastic drugs and sampling locations and to reassess guidance values.

METHODS

Platinum, 5-fluorouracil, cyclophosphamide, ifosfamide, gemcitabine, methotrexate, docetaxel and paclitaxel were analyzed in more than 17,000 wipe samples from 2000 to 2021. Statistical analysis was performed to describe and interpret the data.

RESULTS

Surface contaminations were generally relatively low. The median concentration for most antineoplastic drugs was below the limit of detection except for platinum (0.3 pg/cm²). Only platinum and 5-fluorouracil showed decreasing levels over time. Most exceedances of guidance values were observed for platinum (26.9%), cyclophosphamide (18.5%) and gemcitabine (16.6%). The most affected wipe sampling locations were isolators (24.4%), storage areas (17.6%) and laminar flow hoods (16.6%). However, areas with no direct contact to antineoplastic drugs were also frequently contaminated (8.9%).

CONCLUSION

Overall, the surface contaminations with antineoplastic drugs continue to decrease or were generally at a low level. Therefore, we adjusted guidance values according to the available data. The identification of critical sampling locations may help pharmacies to further improve cleaning procedure and reduce the risk of occupational exposure to antineoplastic drugs.

Establishment-level occupational safety analytics: Challenges and opportunities

In occupational safety and health, big data and analytics show promise for the prediction and prevention of workplace injuries. Advances in computing power and analytical methods have allowed companies to reveal insights from the "big" data that previously would have gone undetected. Despite the promise, occupational safety has lagged behind other industries, such as supply chain management and healthcare, in terms of exploiting the potential of analytics and much of the data collected by organizations goes unanalyzed. The purpose of the present paper is to argue for the broader application of establishment-level safety analytics. This is accomplished by defining the terms, describing previous research, outlining the necessary components required, and describing knowledge gaps and future directions. The knowledge gaps and future directions for research in establishment-level analytics are categorized into readiness for analytics, analytics methods, technology integration, data culture, and impact of analytics.

Reducing workplace unsafe behaviour using risk classification, profiling, risk tolerance approach

Individuals' risk tolerance capacity is one of the primary reasons for their unsafe behaviour at the workplace and is commonly identified as an important causal factor for the majority of workplace accidents. Research has exhibited the significance of individuals' risk tolerance while dealing with risk at workplace. However, limited research is done to explore the influence of various factors on individuals' risk tolerance. In this paper, questionnaire survey (42 questions based on the 36 factors) data were gathered from 606 miners (various category) belonging from three major coal producing subsidiary of northern India. Based on the responses received on the questionnaire survey, (1) Statistical method is used to identify the critical factors (10 critical factors) among all; (2) risk classification (Personal Protective Equipment, operational and others-3 way) system was introduced based on the nature of risk being taken; and (3) organisational risk profiling was done. The methodology of risk profiling and risk classification introduced in this paper will help the organisation identify the critical groups and the nature of the risks being taken, respectively. Further, by considering the combined effect of all three outcomes, necessary compliances can be carried out like design of training module, framing of safety policies and deployment of suitable manpower.

Safe use of PHI6 IN the experimental studies

Surrogate viruses theoretically provide an opportunity to study the viral spread in an indoor environment, a highly needed understanding during the pandemic, in a safe manner to humans and the environment. However, the safety of surrogate viruses for humans as an aerosol at high concentrations has not been established. In this study, Phi6 surrogate was aerosolized at high concentration (Particulate matter_2.5: ∼1018 μg m^-3) in the studied indoor space. Participants were closely followed for any symptoms. We measured the bacterial endotoxin concentration of the virus solution used for aerosolization as well as the concentration in the room air containing the aerosolized viruses. In addition, we measured how the bacterial endotoxin concentration of the sample was affected by different traditional virus purification procedures. Despite the purification, bacterial endotoxin concentration of the Phi6 was high (350 EU/ml in solution used for aerosols) with both (two) purification protocols. Bacterial endotoxins were also detected in aerosolized form, but below the occupational exposure limit of 90 EU/m³. Despite these concerns, no symptoms were observed in exposed humans when they were using personal protective equipment. In the future, purification protocols should be developed to reduce associated bacterial endotoxin levels in enveloped bacterial virus specimens to ensure even safer research use of surrogate viruses.

"I think we still do too little": measures to prevent violence and aggression in German emergency departments - a qualitative study

BACKGROUND

Healthcare workers employed in emergency departments (EDs) are particularly affected by physical and verbal violence. Violent assaults can be committed by both patients and their attendants. Research on interventions for violence prevention is limited and previous studies report that ED employees feel unprepared for violent incidents. Thus, the current study aims to explore ED staff's perceptions regarding available prevention measures, their effectiveness, barriers, and further needs in terms of violence prevention.

METHODS

In accordance with the qualitative study design, 27 semi-structured interviews were conducted via telephone with doctors and nurses working in direct contact with patients in German EDs. Main subjects were advantages and disadvantages of currently available measures, barriers regarding their implementation, their perceived effectiveness, as well as further needs concerning violence prevention. The transcribed interviews were analysed according to Mayring's qualitative content analysis.

RESULTS

Participants described environmental (e.g., alarm systems), organisational (e.g., security service), and individual-focused measures (staff training, verbal de-escalation). Measures perceived as effective were, for instance, communication and security service. Both demands and barriers were often related to financial constraints, e.g., staff shortage led to higher workloads and less time to consider violence prevention. In most cases, guidelines or standard operating procedures (SOPs) regarding violence prevention were missing, unknown, or not perceived as helpful in their current form. Furthermore, screening tools were not applied in any of the EDs.

CONCLUSIONS

The workload in EDs needs to be decreased in order to enable violence prevention, e.g., by reducing patient inflow or by increasing personnel. In addition, violence prevention guidelines tailored to the requirements of the respective ED need to be developed. Hospitals should supply ED staff with such guidelines, e.g., in the form of SOPs, but more importantly, prevention measures have to be practiced and communicated. Furthermore, there is a need for research on the implementation of screening tools for violent behaviour, so that the focus would shift from managing violence to preventing violence.

Field test of two mobile apps for commercial fishing safety: Feedback from fishing vessel captains

BACKGROUND

Unique hazards make commercial fishing a hazardous occupation. Effective safety measures exist, but numerous barriers hinder their adoption. Two mobile apps aim to make performing crucial safety practices easier: the Small Craft Motion Program (SCraMP), which provides vessel stability information, and FVdrills, which provides checklists for running safety drills.

OBJECTIVE

The purpose of this study was to obtain feedback from commercial fishing captains who tested SCraMP or FVdrills for its usefulness during typical fishing operations.

METHODS

A convenience sample of commercial fishing captains with iOS devices tested either FVdrills or SCraMP. After one month, participants provided feedback via online questionnaire. The main outcome variables were self-reported app use and perceived usefulness of the app.

RESULTS

Thirty-two participants who were asked to try FVdrills (n = 16) or SCraMP (n = 16) completed follow-up questionnaires. Twelve participants in the FVdrills group (75.0%) reported using the app. Of these 12, eight (66.7%) rated FVdrills "Very" or "Extremely" useful, and 11 (91.7%) agreed that FVdrills is "easy to use." Nine participants in the SCraMP group (56.3%) reported using the app. Of these nine, only one participant (11.1%) rated SCraMP "Very" or "Extremely" useful and only two (22.2%) agreed that SCraMP is "easy to use."

CONCLUSION

Commercial fishing captains who already own a smartphone or tablet may be willing to try a new mobile app addressing safety issues related to their work. App developers and safety professionals should conduct multiple rounds of formative evaluation, field-testing, and refinement to optimize ease of use and usefulness.

Traumatic injuries among Alaska's young workers: Linking cases from four data systems

BACKGROUND

Young workers (aged 15-24 years) experience higher rates of job-related injury compared with workers aged 25-44 years in the United States. Young workers may have limited or no prior work experience or safety training, which can contribute to their injury risk. In 2018, Alaska had the second highest work-related fatality rate and 14th highest non-fatal injury rate in the United States. This study aimed to characterize nonfatal and fatal occupational injuries among young workers in Alaska.

METHODS

To describe injury patterns among Alaska young workers from 2014-2018, we used data from four datasets: Alaska Workers' Compensation, Alaska Occupational Injury Surveillance System, Alaska Trauma Registry, and Alaska Fishermen's Fund. The datasets were merged two at a time and filtered by the worker characteristics (e.g., age and sex) and incident characteristics (e.g., date of injury). Duplicates were then manually identified between the datasets using the variables above. The injury narrative and Occupational Injury and Illness Classification System codes were used last to verify true duplicates. Descriptive analyses were performed after the duplicates were merged.

RESULTS

During the 5-year study period 2014-2018, young workers experienced 20 fatal and 12,886 nonfatal injuries. Residents of Alaska comprised 85% of nonfatal and 70% of fatal injuries. The top three major occupation groups with the highest number of injuries were production (1,391, 14%), food preparation (1,225, 12%), and transportation/material moving (1,166, 11%). The most common events leading to injuries were struck by object or equipment (2,027, 21%), overexertion involving outside sources (1,385, 14%), and struck against object or equipment (905, 9%). The most common nature of injuries were sprains/strains/tears (3,024, 29%), cuts/lacerations (1,955, 19%), and bruises/contusions (1,592, 15%).

CONCLUSION

Although progress has been made in reducing worker injuries, Alaskan young workers still experience injuries and fatalities frequently. Based on findings, there is a clear need for employers, researchers, public health professionals, parents, and young workers to prioritize young worker safety through an integrated approach, from education and training to adequate workplace supervision and support.

Have you met Angus? Development and evaluation of a social marketing intervention to improve personal flotation device use in commercial fishing

INTRODUCTION

Drowning is the leading cause of death among commercial fishermen in the United States. Approximately 30% of all commercial fishing fatalities are attributed to falls overboard. One of the simplest and most affordable ways to prevent these fatalities is for crewmembers to wear personal flotation devices (PFDs) while on deck. An examination of over 200 fatal falls overboard in the U.S. fishing industry revealed that none of the victims were wearing PFDs when they died. PFDs are not required to be worn by commercial fishermen in the United States, so this study was designed to encourage behavior change using targeted health communication and social marketing.

METHODS

This study developed, implemented, and evaluated a multi-media social marketing campaign featuring a fictitious, culturally-relevant spokesman designed to look, talk, and act like the target audience. The messages were crafted to address common barriers to PFD adoption and misconceptions about fleet-specific risks for fatalities from falls overboard. The campaign was evaluated over two seasons of fishing to look at message retention and intent toward action following exposure to the campaign materials.

RESULTS

Survey respondents indicated overall positive opinions about the spokesman and the messages. Results also show a reported change in behavior related to using PFDs while working on deck.

DISCUSSION

Targeted multi-media messaging can influence behavior of workers in high-risk occupations in remote locations. Safety message development should focus on occupational culture to create valid and authentic communication products for workers in high-risk industries.

Hygiene knowledge and practices and determinants of occupational safety among waste and sanitation workers in Bangladesh during the COVID-19 pandemic

Waste and sanitation workers provide essential services to society. In most low-and middle-income countries, they are often mistreated and lack access to necessary personal protective equipment (PPE) and hygiene facilities that ensure occupational safety in workplaces. COVID-19 has also imposed serious health risks upon these worker groups. This study explores factors associated with poor occupational health and safety based on a conceptual framework. We conducted 499 surveys with five categories of waste and sanitation workers across ten cities in Bangladesh. We performed descriptive analysis and used Firth's logistic regression model following the conceptual framework. The analysis revealed consistent distinctions between workers considered to be in "safe" versus "unsafe" working conditions. The result showed that workers had not been adequately trained, not provided with proper equipment, and many had an informal status that prevented access to hygiene facilities. The workers who received occupational training, knew how to prevent COVID-19 by wearing a face mask, hand washing, and maintaining social distance, maintained protective measures, and practiced proper disposing of PPEs were more likely to be in safe condition. Initiatives to improve the situation of the waste workers who work in unsafe work conditions are still inadequate. Therefore, we recommend supplying proper protective equipment, ensuring a regular supply of gender-specific PPEs, and providing functional facilities necessary to practice personal hygiene and occupational safety, such as handwashing stations, changing rooms, and disposal facilities of used PPEs at the workplace. We also urge increased institutional management procedures, infrastructure that facilitates hygiene practices, and social policies to reduce occupational hazards for the waste workers in Bangladesh during and beyond the COVID-19 pandemic.

Adapting, adopting, and advancing change: A framework for future research in the psychology of occupational safety

INTRODUCTION

While there are numerous reviews of the research on the psychology of occupational safety, these studies provide weak guidance on where the research should go next. Accordingly, we introduce a simple framework for thinking about future research in this area: the adapting, adopting, and advancing change framework. This framework summarizes how external, technological, and theoretical developments have driven research in the psychology of occupational safety and uses these observations as evidence to imagine ways in which they may continue to do so.

METHOD

We critically reviewed seminal research in the psychology of occupational safety using the adapting, adopting, and advancing change framework. Adapting to change means considering external changes such as the fluctuating nature of work and the labor market. Adopting change refers to incorporating the latest technological and technical advances to facilitate more robust research methods and analyses. Finally, advancing change refers to theoretical advances and how they will push psychology of occupational safety research forward.

RESULTS

We highlight several avenues for future research that emerge at the convergence of the framework's three themes, including developing the safety skill construct, assessing variation in demand appraisals on safety outcomes, distinguishing safety climate from related constructs, and examining safety constructs that are usually considered as outcomes (e.g., injuries) as predictors instead.

CONCLUSIONS

In doing so, we provide a clear structure to help researchers better identify the most effective directions for future research on the psychology of occupational safety.

The occupational safety implications of the California residential rooftop solar photovoltaic systems mandate

INTRODUCTION

A 2018 change to the California building code mandates that new residential construction in the state include rooftop solar photovoltaic power systems beginning in 2020. As residential construction (especially work on rooftops) is among the more dangerous occupations in the United States, this paper seeks to quantify the increased risks to workers as a result of this mandate.

METHOD

An analysis of the trends by occupation of nonfatal safety incident rates in the United States combined with a Monte Carlo simulation provide an estimate of the uncertain impact of this new mandate.

RESULTS

Recordable safety incidents are anticipated to increase by a total of 16.6 incidents (standard deviation = 1.0 incidents) over the 2020-2029 time period as a result of this policy change. However, lessons from Germany and other industries offer potential avenues to reduce the negative social impact of this mandate.

CONCLUSIONS

While it is not possible to increase employment in any sector without increasing the expected number of occupational injuries to some degree, these results indicate that risks could be considerably reduced by making solar PV system design decisions that increase worker productivity and reduce roof exposure time.

PRACTICAL APPLICATIONS

Changes such as eliminating work on roofs could decrease the expected number of recordable injuries over the 10-year period by 0.30 incidents per year (a reduction of 18%).

Safer tomorrow: Irish dairy farmers' self-perception of their farm safety practices

INTRODUCTION

Encouraging safe work practices (SWPs) is challenging in agriculture. Group-based social learning has effectively promoted SWPs and health behaviors in other occupations, and could be applied in agriculture (e.g., through farmer discussion groups (DGs)). In Ireland, dairy DG members are more likely to adopt novel technologies and practices, a relationship that might extend to SWPs. The extent of SWP adoption among Irish dairy farmers is unknown. This paper evaluates a 2018 baseline study of SWP implementation, conducted as part of a dairy DG-based intervention study.

METHOD

A paper-based survey of SWP implementation and safety self-perception was distributed to 1,220 farmers from 84 dairy DGs. For eight SWPs, associated with high-risk farm hazards (livestock, slurry, machinery, or tractors), farmers were asked how frequently they implemented these practices in the previous year, and how frequently they intended to do so next year (0: never, 1: rarely, 2: sometimes, 3: most of the time, 4: all of the time).

RESULTS

Surveys were completed by 460 farmers. For the previous year, three SWPs, related to slurry, machinery, and tractor hazards, scored a median frequency of four. Four SWPs, related to livestock, slurry, and machinery hazards, scored a median frequency of three. The lowest median score (two) was for tractor exit behavior. Median intention scores matched or exceeded past frequency for all SWPs, while 73% intended to increase implementation of at least one SWP. Most (96%) considered themselves a "safe farmer."

CONCLUSIONS

Farmers generally perceived themselves to be safe at work, which is reflected in their SWP implementation. Most farmers intended to increase SWP implementation, suggesting awareness of safety shortcomings and a desire to farm more safely.

PRACTICAL APPLICATIONS

This study can inform farm safety promotion initiatives. The disconnect between farmers' safety self-perception and SWP implementation merits further research.

The effect of an embargo, sanctions and culture on safety climate: A qualitative view from aviation maintenance in the MENA region

INTRODUCTION

Safety climate assessment is a key measure of organizational safety. A strong safety climate is integral to the high safety performance in aviation. Most survey instruments that purport to measure safety climate are derived from evidence obtained in developed countries in the west. It is rare for these studies to examine the influence of macro-environmental factors on safety climate, and rarer still in countries found in the Middle East and North Africa (MENA) region.

METHOD

The researchers conducted 28 semi-structured interviews with experienced aviation maintenance engineers from a national carrier in the region. The interview questions were derived from an extensive review of existing studies of safety climate. Data from interview transcripts were coded, creating a data structure using participant quotes for 1st order codes and arriving at three aggregate dimensions: organizational commitment to safety, organizational safety practices and social relationships and their consequences.

RESULTS

Commercial considerations influenced negatively organizational commitment to safety. Organizational safety practices were weak. There was a lack of safety training, a lack of resources to support safe working, poor safety communication, and a failure to report safety issues. Strong friendships were developed through working together in teams. This adversely influenced the reporting of errors and the punishment of violations.

DISCUSSION AND CONCLUSION

The apparently weak organizational safety climate reported here was attributed to financial constraints following the imposition of economic sanctions and embargos, and to the influence of Arabic cultural values that privilege family connections and the importance of maintaining harmony in social relationships that precludes punishment.

PRACTICAL APPLICATION

Financial constraints inevitably limit resources for safety and encourage prioritization of production. Arabic cultural values inhibit the development of a 'just' culture and a 'reporting' culture and challenge the universal adoption of approaches for promoting organizational safety developed in the West.

[Risk communication for protection against hazardous substances in the workplace]

Gefahrstoffe sind in der Arbeitswelt allgegenwärtig. Beschäftigte aus allen Branchen sind bei ihrer Arbeit mit Gefahrstoffen unterschiedlichen Risiken ausgesetzt. Dies betrifft auch Personen, die nicht unmittelbar mit Gefahrstoffen umgehen (Bystander). Risikokommunikation im Arbeitsschutz spricht verschiedene Zielgruppen an. Das Spektrum reicht vom Groß- zum Kleinunternehmer über Sicherheitsfachkräfte, Betriebsärzte, Betriebs- und Personalräte bis hin zu den Beschäftigten und der breiten Öffentlichkeit. Risikokommunikation im Arbeitsschutz hat das Ziel, entlang von Lieferketten Risikobewusstsein bei Herstellern, Arbeitgebern und den Beschäftigten zu schaffen, risikohaftes Verhalten zu vermindern und risikominderndes Verhalten zu bestärken.

In diesem Beitrag werden Instrumente der Risikokommunikation erläutert und bezüglich ihrer Wirksamkeit betrachtet. Das betrifft verbindliche Instrumente im europäischen Binnenmarkt wie das Gefahrenetikett oder das Sicherheitsdatenblatt (SDB). Auf Ebene der Gefahrstoffverordnung sind es die Technischen Regeln für Gefahrstoffe (TRGS), Grenzwerte, das Einfache Maßnahmenkonzept Gefahrstoffe (EMKG) und als kreatives Instrument die Objekte der „DASA Arbeitswelt Ausstellung“ in Dortmund. Der Beitrag zeigt, dass eine Anpassung der Instrumente besonders für kleine und kleinste Unternehmen notwendig ist, damit diese einen passenden Einstieg in die Risikobewertung finden. Oft sind diesen die vorhandenen Instrumente nicht bekannt, zu umfangreich oder schwer verständlich. Handlungsempfehlungen wären hier hilfreich. Vorliegende wissenschaftliche Studien konzentrieren sich eher auf die Defizite in der Risikobewertung als auf die Entwicklung von effizienten Wegen der Risikokommunikation. Hier sind weitere Analysen der Bedürfnisse unterschiedlicher Zielgruppen für eine adressatengerechte Risikokommunikation erforderlich.

Will the real relationship between lean and safety/ergonomics please stand up?

This paper provides a review of studies containing safety and ergonomic outcomes in lean manufacturing (LM) environments over the past 40 years. The aim is to identify effects from specific LM methods on specific safety/ergonomic outcomes, to understand the relationship in greater detail. One hundred and one studies containing one hundred and seventy outcomes were identified. Thirty-seven outcomes pertained to just-in-time (JIT) production, which contained twenty-three negative, eleven neutral, and three positive safety/ergonomic outcomes. Conversely, twenty-six outcomes pertained to 5S and consisted of twenty-four positive, two negative, and no neutral outcomes. The most common negative JIT outcome was stress and mental strain, while the most common positive 5S outcome was a tie between safety performance and hazard exposure. Studies containing other methods were fewer in number with more mixed outcomes. These findings suggest that individual LM methods, especially JIT and 5S, uniquely contribute to the safety/ergonomic outcomes attributed to LM.

Using a human factors-centric approach to development and testing of a face shield designed for health care workers: A COVID-19 case study for process and outcomes

Background

Face shields are a critical piece of personal protective equipment and their comfort impacts compliant use and thus protectiveness. Optimal design criteria for face shield use in healthcare environments are limited. We attempt to identify factors affecting face shield usability and to test and optimize a face shield for comfort and function in health care settings.

Methods

A broad range of workers in a large health care system were surveyed regarding face shield features and usability. Quantitative and qualitative analysis informed the development of iterative prototypes which were tested against existing shields. Iterative testing and redesign utilized expert insight and feedback from participant focus groups to inform subsequent prototype designs.

Results

From 1,648 responses, 6 key elements were identified: ability to adjust tension, shifting load bearing from the temples, anti-fogging, ventilation, freedom of movement, and durability. Iterative prototypes received consistently excellent feedback based on use in the clinical environment, demonstrating incremental improvement.

Conclusion

We defined elements of face shield design necessary for usability in health care and produced a highly functional face shield that satisfies frontline provider criteria and Emergency Use Authorization standards set by the Food and Drug Administration. Integrating human factors principles into rapid-cycle prototyping for personal protective equipment is feasible and valuable.

Promoting farming sustainability: The effects of age, training, history of accidents and social-psychological variables on the adoption of on-farm safety behaviors

INTRODUCTION

Occupational safety and health (OSH) have a remarkable impact on the sustainability of firms and organizations. However, the sustainability perspective has often focused primarily on environmental and economic concerns, leaving key social and workplace aspects, such as OSH, underemphasized. The link between all these aspects is particularly relevant in agriculture.

METHOD

In the present study we analyzed the paths by which the worker's age, participation in safety training, and previous history of accidents and near misses can influence the adoption of safety behaviors in agriculture through the mediation of attitudes towards safety and perceived behavioral control. Three hundred and ten Italian agricultural operators were administered an ad-hoc questionnaire.

RESULTS

Having attended safety training courses, having been exposed to previous accidents and near misses, and age showed a positive association with the adoption of on-farm safety behaviors, through the mediation of perceived behavioral control. In more detail, participation in training courses and age showed a positive association with perceived behavioral control, while the previous history of accidents and near misses showed a negative association with behavioral control. In turn, perceived behavioral control was positively associated with the adoption of safety behaviors.

CONCLUSIONS

The present study focused on the chain of events leading to the adoption of on-farm safety behaviors, which can prevent an accidents, pointing out the more critical variables and the level at which they intervene, identifying possible areas of targeted interventions. Practical applications: Implications for the development of targeted interventions may deal with: (a) training activities increasing farm operators' sense of control over their safety, (b) older farmers involvement in mentoring initiatives, and (c) systematic recording and use of previous history of accidents and near misses as inputs for training activities to discuss their implications for on-farm safety.

Characterizing accident narratives with word embeddings: Improving accuracy, richness, and generalizability

INTRODUCTION

Ensuring occupational health and safety is an enormous concern for organizations, as accidents not only harm workers but also result in financial losses. Analysis of accident data has the potential to reveal insights that may improve capabilities to mitigate future accidents. However, because accident data are often transcribed textually, analyzing these narratives proves difficult. This study contributes to a recent stream of literature utilizing machine learning to automatically label accident narratives, converting them into more easily analyzable fields.

METHOD

First, a large dataset of accident narratives in which workers were injured is collected from the U.S. Occupational Safety and Health Administration (OSHA). Word embeddings-based text mining is implemented; compared to past works, this methodology offers excellent performance. Second, to improve the richness of analyses, each record is assessed across five dimensions. The machine learning models provide classifications of body part(s) injured, the source of the injury, the type of event causing the injury, whether a hospitalization occurred, and whether an amputation occurred. Finally, demonstrating generalizability, the trained models are deployed to analyze two additional datasets of accident narratives in the construction industry and the mining and metals industry (transfer learning). Practical Applications: These contributions improve organizations' capacities to rapidly analyze textual accident narratives.

Analyzing occupational heat stress using sensor-based monitoring: a wearable approach with environmental ergonomics perspective

Occupational heat stress could impose a greater risk of heat-related morbidities among the exposed users, declining their work productivity and contributing to a financial burden. This necessitate the implementation of adequate preventive measures and control policies to improve the users' well-being and productive capacity. The emergence of modernistic sensors gives rise to workplace heat stress monitoring at a substantially lower cost than expensive conventional equipment. Present work unveils the productive role of sensor-based safety helmet, which could monitor the environmental variables, heat stress indices, and users' physiological variables as an indicator of heat strain. The proposed safety helmet was tested under three different work environments with users' engaged in specific work activities. Notable variations were perceived among the measured data under respective work conditions and physical activity performed. Higher heat risk exposures were attributable to the outdoor condition compared to indoor work conditions. For wet bulb globe temperature index, strong association (p-value < 0.01) was observed with fighter index of thermal stress (R ²-value = 0.959) followed by discomfort index (R ²-value = 0.899) and heat index (R ²-value = 0.867). Results revealed a rise in measured physiological parameters under the heavy workload activity (shoveling task; outdoor location) followed by hacksaw cutting task (indoor location), while least values were associated with light workload activity (drilling task; indoor location). The proposed design intervention could be considered an effective site-specific solution for monitoring heat stress exposures and keeping exposed users well aware of the prevalent thermal work conditions at the individual level.

Occupational vs. non-occupational equestrians: Differences in demographics and injury patterns

INTRODUCTION

Nineteen million people participate in horseback riding activities in the US, and the horse industry employs more than 460,000 full-time workers. Emergency department data suggest young female amateurs and male professionals are most at risk of death from horse-related injuries. However, there has been no investigation into factors that may increase severe injury and mortality risk in these populations. This study investigates demographics and injury pattern differences between occupational and non-occupational horse-related injuries in the US.

METHODS

The 2017 American College of Surgeons National Trauma Databank (ACS NTDB) was analyzed for horse-related injury using ICD 10 codes. Demographics, injury data, protective device use, and hospital procedures were analyzed. Occupational versus non-occupational injuries based on incident location (farm, sports, recreational, residential) were compared using ANOVA or Pearson's Chi-squared test.

RESULTS

Of 3911 incidents, the most common injury mechanism was falling from the horse, but occupational and non-occupational farm injuries showed higher incidence of being struck by a horse. One-third required surgery. Upper extremity injuries were most common. Occupational injuries more often affected upper extremities of working age, minority males with commercial insurance. Non-occupational injuries most often affected heads of women at the extremes of age. Helmet use was higher in occupational, non-occupational sports, and non-occupational recreation injuries, and severe head injury incidence was decreased in these groups. Complications and discharge dispositions were not different across groups.

CONCLUSIONS

In the largest trauma center study to date, we have shown equine-related trauma to be common and affect a predictable demographic that may permit injury prevention initiatives. Helmets may reduce severe head injury, but the efficacy of protective clothing remains to be validated.

On-site personal protective equipment signage and use by road construction workers in Ghana: a comparative study of foreign- and locally-owned companies

Background

Road construction work has specific risks and safety issues which have not been adequately addressed in most low- and middle-income countries, especially Africa. The objective of this study was to determine the prevalence of personal protective equipment (PPE) use during road construction activities by workers in foreign- owned against locally-owned road construction companies in Ghana.

Methods

An institution-based cross-sectional survey was undertaken during January – March, 2020 to study 389 road construction workers who were actively working on site. They were unobtrusively observed to capture whether or not they wore the appropriate PPE at the time of the survey. The PPE of interest were: hard hat, goggles, shoes, nose masks, hearing protection, gloves and reflective vests/apparel. On-site posted PPE signage was also checked.

Results

Majority of workers were males (96.9%) and labourers (53.5%). Similar numbers of workers in locally-owned (195) and foreign-owned (194) companies were studied. Use of PPE varied considerably by type: shoes (78.7%), reflective vest (44.5%), gloves (30.6%), hard hat (27.0%), nose mask (17.2%), goggles (11.3%) and hearing protection (10.8%). For all types of PPE, use was higher for workers in foreign-owned companies compared with locally-owned companies: goggles (Odds ratio [OR] 55.2), hearing protection (OR 52.0), gloves (OR 23.7), hard hat (OR 20.2), nose mask (OR 17.8), reflective vest (OR 5.3) and shoes (OR 4.1), (p<0.001 for all ORs). No site had any signage to promote PPE use.

Conclusions

Majority of workers used shoes. Less than half of workers used other types of PPE and use of some types (goggles and hearing protection) was minimal. Workers in foreign-owned companies were significantly more likely to use all the seven types of PPE than locally-owned companies. Although there is still room for improvement in foreign-owned companies, locally-owned companies should be able to attain similar PPE use to that in foreign-owned companies. Necessary PPE should be provided and site supervisors should encourage workers to wear PPE when on site.

The Impact of Adverse Employment and Working Conditions on the Risk of Workplace Injury in Canada

Background

Employment standards (ES) include having a regular payday, regular breaks, the right to paid sick or vacation time, and paid wages. Inadequate ES contribute to the labour market vulnerability of workers; however, they are not typically considered to be risk factors for workplace injury. In a sample of Canadian workers, we examine the risk of injury associated with inadequate ES, independent of, and combined with inadequate workplace protections from workplace hazards.

Methods

Data from 2,803 adults working 15 hours or more/week in workplaces with at least five employees were analysed. We explored associations between exposure to workplace hazards with inadequate protections [termed occupational health and safety (OHS) vulnerability] and inadequate ES on workplace injury (physical or mental injury; injury requiring time off). Additive interaction models were used to examine the independent and combined effects of these exposures.

Results

Occupational health and safety vulnerability and inadequate ES were independently associated with increased injury outcomes. Adjusted models showed an additive relationship for all injury outcomes between OHS vulnerability and inadequate ES. Statistically significant superadditive relationships were observed for physical injury risk with policy and procedure vulnerability plus inadequate ES [synergy index (S) 1.50, 95% CI: 1.13-2.00] and for overall OHS vulnerability plus inadequate ES (S 1.53, 95% CI: 1.16-2.02), suggesting a combined effect greater than independent effects.

Conclusion

Occupational health and safety vulnerability and inadequate ES are independently associated with workplace injury. For certain injury outcomes, the combined effect of OHS vulnerability and inadequate ES is greater than the independent effects of each individual exposure.

Systematic review of occupational hazards at postharvest grain operations

INTRODUCTION

Agriculture stands out in relation to the high number of occupational incidents and diseases. In this sense, grains postharvest operations, such as receiving, precleaning, drying, storage and shipping the grains, are highlighted in the number of injuries and fatalities.

AIM

To identify and extract qualitative and quantitative data related to the main occupational hazards present in grains postharvest operations at preprocessing and storage facilities.

METHODS

A systematic review was carried out in the databases of Science Direct, Scopus and Web of Science for papers published between 1980 and 2019. The abstract should have described a study related to any occupational hazard (physical, chemical, biological, ergonomic and mechanical) and at least one of the occupational hazards should be related to any postharvest operations.

RESULTS AND DISCUSSIONS

In total, 42% of 38 analysed papers were published between 2015 and 2019. Three journals were responsible for 45% of publications related to occupational hazards present in grains postharvest operations. The most part of analysed publications related to confined spaces, grain entrapment, machine entanglement and falls hazards are related to Purdue University's Agricultural Safety and Health Program which applied research in occupational safety at grains postharvest.

CONCLUSIONS

The creation of standardised internationals can collaborate to reduce occupational risks in grain storage units. It is suggested the development of monitoring technologies to obtain real-time information on noise, dust, gases and heat in postharvest operations and equipment. The use of intelligent algorithms can create prevention mechanisms for possible occupational risks and avoid injuries to employees.

Evaluation of the environmental contamination and exposure risk in medical/non-medical staff after oxaliplatin-based pressurized intraperitoneal aerosol chemotherapy

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a technique to directly deliver chemotherapeutic drugs in the abdomen for the treatment of peritoneal metastases. Pressurization improves the treatment efficacy but increases the risk of exposure for the medical/non-medical staff who can be exposed by dermal or ocular contact, or inhalation of aerosols containing the cytotoxic drugs. The aim of this study was to evaluate the risk of exposure for the medical/non-medical staff (nurses, surgeons, anaesthesiologists and cleaning personnel; n = 13) during PIPAC with oxaliplatin performed according to the protocol recommended in France. Blood samples were collected 1 h before and immediately after PIPAC, and urine samples 1 h before, and then 3 h and the morning after PIPAC. In the control, non-exposed group (n = 7), only one urine and blood sample were collected. Surface contamination in the operating room was assessed in water- and Surfanios-impregnated wipe samples. The total elemental platinum in each sample was quantified by inductively coupled plasma mass spectrometry, using a method adapted to quantify trace amounts (ng.L^-1) in very low volumes (100 μl). No surface contamination was detected. Although 25% of urine samples in the exposed group contained platinum, no statistical difference was observed in urine and plasma samples collected before and after PIPAC and with the control group samples. These findings suggest that the French PIPAC protocol does not increase the risk of exposure to platinum in all staff categories involved. This protocol could be considered in future occupational policies and consensus statements. Trial registration: NCT04014426.

Ergonomics of Endoscopy

Optimal endoscopic operations incorporate ergonomic principles into the endoscopy environment benefiting endoscopists, endoscopy unit personnel, and patients. A high prevalence of occupational musculoskeletal injuries is well established among endoscopists and gastroenterology nurses. Ergonomics can be integrated into all facets of the endoscopy unit including scheduling, endoscopy unit design, training programs, and investment in technology. Preprocedure, intraprocedure, and postprocedure areas should aim to deliver patient safety, privacy, and comfort, while also supporting endoscopists and staff with adjustable rooms and effective work flows. Team-wide educational initiatives can improve ergonomic awareness. These strategies help mitigate risks for musculoskeletal injuries and can lead to increased productivity. The COVID-19 area brings novel challenges to endoscopy.

Occupational Safety in Chemosensitivity Tests: A Method to Minimize the Risk of Contamination While Maximizing the Safety for the Examiner

In vitro chemosensitivity tests are a widely used and established method in research. In laboratory environments, work safety is particularly important when working with carcinogenic, mutagenic, or reprotoxic (CMR) substances. When working with cell cultures, minimizing the risk of contamination with CMR substances and protecting the experimenter must be in the foreground of the experimental setup since risk minimization and occupational safety when handling CMR substances are mandatory. To minimize any personnel risk, studies with solid CMR substances should be carried out in a closed system. However, publications on occupational health and safety in laboratory environments in which CMR substances are tested in cell cultures are rare. Therefore, this article presents an easily applicable and safe method for improving work safety for in vitro chemosensitivity tests when working with CMR substances while also taking cell culture hygiene into account. For this purpose, a risk assessment of the test design was carried out, and the steps that were decisive for safety were highlighted. Some user-friendly and easily reproducible elements are presented, which increase the occupational safety of in vitro chemosensitivity assays, especially by reducing the risk of personnel contamination.
