Personal protective equipment (PPE) use and its relation to accidents among construction workers

Prevalence of injury and utilization of personal protective equipment among building construction workers and associated factors in Bale and West Arsi Zones, southeast Ethiopia 2022

Introduction

The building construction industry is well known for being one of the most dangerous industries worldwide. Statistics show it is one of the most dangerous occupations in the world. The aim of this study is to assess the prevalence of injury, personal protective equipment usage among building construction workers, and associated factors in Southeast Ethiopia.

Methods

Institutional-based cross-sectional study was done among 406 selected construction workers in Southeast Ethiopia. Study participants were selected randomly. Data were collected by using a structured questionnaire. Descriptive statistics was used to summarize study variables. Binary logistic regression was utilized to investigate factors associated with injury among study participants. Accordingly, adjusted odds ratio along its 95% confidence interval were calculated and a p value of <0.05 was used to declare statistical significance. Generalized linear models were utilized to investigate factors associated with the use of personal protective equipment. Accordingly, an adjusted odds ratio with a 95% confidence interval was determined and a p value of <0.05 was used as a level to declare a significant statistical association.

Result and discussion

In this research 406 building construction workers were interviewed and 393 participants gave complete responses, yielding a 96.8% response rate. Of all participants included in this study, 27 (6.8%) drink alcohol and 26 (6.6%) chew khats. Uses of personal protective equipment among study participants was 133 (33.3%, with a 95% confidence interval of 28.3% to 37.7%). Of 393 participants in this study, 213 (54.2%) of them sustained at least one building work-related injury in the last year. The commonest type of injury that occurred among this population was abrasion 43.3% followed by muscular pain (13%). Not having orientation about personal protective equipment, without safety training, didn't use personal protective equipment, and rural residence were factors significantly associated with injury among building construction workers. Residence, age, monthly income, service year, orientation about personal protective equipment, safety training, and start using personal protective equipment immediately after the job offers were significantly associated with the uses of personal protective equipment by participants of this study. In general, this study has identified a relatively high prevalence of injury and low use of personal protective equipment in the study subjects and associated factors.

Evaluation of Personal Protective Equipment Usage Among Construction Workers in Erbil City, Iraq

Background and aim The construction industry is a high-risk environment where the use of personal protective equipment (PPE) is essential for worker safety. Despite the clear benefits of PPE, compliance rates among construction workers are often suboptimal. In response to these concerns, this study aimed to assess the knowledge and attitudes regarding PPE usage among construction workers in Erbil City, Iraq. Methods This cross-sectional study was conducted from December 15, 2022, to June 15, 2023, among construction workers in Erbil. Convenience sampling was used to collect data through a self-structured questionnaire. The questionnaire collected demographic information, as well as responses to a 15-item Knowledge Questionnaire and an 8-item Attitude Questionnaire. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 28 (Released 2021; IBM Corp., Armonk, New York). Frequency and percentage were used to describe qualitative variables, while mean and standard deviation were calculated for quantitative variables. Parametric tests such as the independent sample t-test and ANOVA were used, along with multinomial logistic regression, to assess the relationships between knowledge, attitude, and various demographic factors. Results A total of 280 workers participated in the study. The mean knowledge score was 13.56 ± 1.17, indicating a good level of knowledge, while the mean attitude score was 6.86 ± 1.11, reflecting a fair attitude toward PPE usage. A significant majority of the participants, 97.9% (274), were categorized as having good knowledge, while 68.2% (191) exhibited a fair attitude towards PPE usage. The analysis showed that demographic factors such as age, marital status, working hours, work experience, and employment type did not significantly affect knowledge or attitude, with all odds ratios (ORs) near 1 and P-values above 0.05. Conclusion The findings indicate that construction workers in Erbil generally have good knowledge but only a fair attitude toward PPE usage. These results suggest that healthcare providers and policymakers should implement targeted educational interventions to improve workers' attitudes toward PPE, aiming to boost compliance and enhance workplace safety. Additionally, these interventions should address practical barriers to PPE usage, such as discomfort or lack of accessibility. By fostering more positive attitudes and ensuring the availability of necessary resources, overall safety in the construction industry can be significantly improved.

Assessing personal protective equipment usage and its correlation with knowledge, attitudes, performance, and safety culture among workers in small and medium-sized enterprises

BACKGROUND

The use of personal protective equipment (PPE) should be a culture of a workplace, and deeply rooted in worker behavior and attitude during their practice. According to the recent studies only 64% of the workers use PPE properly. The present study aims to investigate the utilization of PPE among workers in small and medium-sized enterprises (SMEs), and its relationship with knowledge, attitude, performance, and safety culture among workers.

METHODS

This cross-sectional study was carried out using a questionnaire tool across SMEs in Kashan city in year 2023. The used tool included three questionnaires: demographic, safety culture, and knowledge, attitude and performance. Study papulation was 529 SMEs. Totally, the sample size was 369 persons and questionnaires were distributed among the workers of SMEs. Finally, SPSS software was used for statistical analysis and structural equation modeling. Various statistical tests including T-Test, ANOVA, RMSEA, CFI, TLI, and the chi-square ratio were employed.

RESULTS

The mean values (standard deviation) of age and work experience were 35.19 (12.33), and 15.60 (1.69) years, respectively. Among the 369 participants, 267 participants (72.4%) indicated that they use some PPE, although not all types. However, 102 individuals (27.7%) do not employ any PPE. The lowest score for safety culture dimension was attributed to safety training at 1.58. The results of the final model indicate that the assumed relationships between variables, as outlined in the study objectives, were well established, with all connections proving statistically significant.

CONCLUSION

It can be concluded that the missing of inadequate legal supervision for small industries exists. Therefore, it can be inferred that if supervision and regulation are enhanced for safety training and implementation that may lead to increased usage of PPE.

Occupational accidents and the use of PPE: a global meta-analysis

Occupational accidents, despite continuous safety updates, are still a scourge in the occupational and forensic spheres, constituting, among other things, the subject of a large share of litigation. Demographic data can help to understand the areas where the application of health surveillance is lacking. This meta-analysis sets out to analyse data from studies on accidents at work, focusing on the correlation between the areas in which accidents occur and whether or not personal safety equipment is used, in relation to the different regulations in force. For the selection of the data, a systematic review was carried out according to the PRISMA guidelines, with the primary objective of identifying the trend of occupational accidents in specific geographical areas, which differ in terms of the attention paid to preventive aspects. The data we highlighted showed, regarding the type of accident, substantial differences between low-income countries and industrialised countries (stratified according to the Human Development Index) and, an overall indifference as to whether or not individual safety devices were used, revealing that, despite the continuous normative evolution in the field of safety at work, even today, the investigative data on the actual application of the regulations, during accidents at work, is underestimated and little researched.

Evaluating the impact of different hard hats on the peripheral vision of construction workers

Construction safety is always an issue for construction workers. Hence, personal protective equipment plays a critical role in avoiding potential hazards on construction sites. Among these, hard hats protect against head contact with falling objects on construction sites. This study aims to examine the effects of hard hats with different peak lengths on the field of view at different angles in the upward part and to examine the effects of possible field of view losses caused by the hard hat on the reaction times of the workers. A questionnaire was designed and administered to the construction workers. Experiments were then conducted with a group of subjects to assess their peripheral vision level as well as reaction times. The study found that peripheral vision is affected by the peak size of hard hats. The study further revealed that there is a significant relationship between reaction times and hard hat peak size.

Prevalence and associated factors of occupational injuries in an industrial city in Ghana

BACKGROUND

Workers are exposed to workplace hazards which increase their risk of occupational injury. Data on occupational injuries and associated factors are important for planning and informing national policy regarding workplace health and safety. This study sought to estimate the prevalence and factors associated with occupational injuries among workers in an industrial city in Ghana.

METHODS

A community-based cross-sectional survey was conducted among 459 workers in the Tema industrial enclave in Ghana from 22nd December 2020 to 27th February 2021. Participants were recruited using a two-stage sampling technique. Eight communities were randomly selected from twenty-five communities in the first stage while households in each community were randomly selected in the second stage. Data on socio-demographic characteristics, occupational health and safety and occupational injuries were collected. Logistic regression was used to examine the relationship between occupational injuries and associated factors.

RESULTS

The mean age of the workers was 33.9 (±6.8) years with a range of 21-53 while over 18.1% of them were working at the Port and Harbour. The prevalence of occupational injury among the workers in the preceding twelve months was 64.7%. The mechanism of injury was mainly the use of working tools (45.8%) and hot surfaces, substances or chemicals (14.1%). Being a casual staff (AOR: 2.26, 95%CI: 1.04-4.92), working at Port and Harbour (AOR: 3.77, 95%CI: 1.70-8.39), no health and safety training (AOR: 2.18, 95%CI: 1.08-4.39), dissatisfaction with health and safety measures (AOR: 4.31, 95%CI: 2.12-8.78) and tertiary education (AOR: 0.03, 95%CI: 0.01-0.10) were significantly associated with occupational injuries.

CONCLUSION

The prevalence of occupational injuries in this study was high. Promoting machine tools' safety, health and safety training, and satisfaction with health and safety measures through rewarding workers who do not sustain injuries could be key to employees' health and safety.

Comprehensive factor analysis and risk quantification study of fall from height accidents

Working at heights poses frequent and significant risks, demanding scientific approaches for investigating fall-from-height (FFH) incidents and proposing preventive measures to enhance building safety. Nevertheless, ongoing research on analyzing the causal factors behind fall-from-height accidents lacks a comprehensive qualitative and quantitative assessment of the interplay between these factors. To bridge this gap, this study introduces an integrated risk analysis model. Utilizing incident reports and leveraging the multi-case rootedness theory, the model initially identifies influential elements. Subsequently, employing the Grey Decision Making Laboratory (Grey-DEMATEL) and Interpretive Structural Modeling (ISM) techniques, a hierarchical network is constructed, followed by the transformation of this hierarchical network model into a Bayesian Network (BN) model using GeNie2.0 software. Ultimately, the study was based on data from 420 accident cases and analyzed the causes and diagnosis of the accidents. The findings indicate that A5 (Low-security awareness) is the most significant factor contributing to falls from great heights and that the connection between the components is dynamic and non-linear rather than simply independent and linear. Furthermore, the study established a likelihood of occurrence of such incidents of up to 57 % and ranked the probability of occurrence of each contributing component in the case of a fall from height. This study presents a scientifically valid method for analyzing fall-from-height accidents. Experimental results confirm the model's applicability, empowering contractors to improve safety management by accessing precise risk information and prioritizing preventive measures against interrelated accidents. The model facilitates informed decision-making for contractors to effectively mitigate fall-from-height risks and establish a safer working environment.

A retrospective observational study of injury patterns associated with powered circular saw in subjects presenting to the emergency department of a tertiary care hospital

Background

Powered circular saw-related injuries (PCSRIs) are responsible for a sizable proportion of occupational injuries presented to the emergency department (ED). The present study portrays the mechanisms, injury patterns, epidemiological parameters, and outcomes among subjects presenting with PCSRI to the ED.

Methods

This retrospective observational study was conducted in the ED of a tertiary care hospital in eastern India. Clinical records of subjects with PCSRI from June 2019 to June 2022 were reviewed. Data pertaining to patients' demographic profiles and the patterns and mechanisms of injury were retrieved. The Modified Hand Injury Severity Score (MHISS) and the Injury Severity Score (ISS) were calculated. Statistical analysis was performed using R version 4.1.0.

Results

A total of 175 subjects' data were analyzed. The median age was 34.5 years, and all subjects were men. The mean year of experience of the subjects was 6.2. The most common job category was carpentry (n = 63 [36%]), followed by "do it yourself work" (n = 26 [14.8%]). One hundred twenty-two (69.7%) subjects had hand injuries (HIs), and the left hand was involved in 85 (69.6%) subjects. The index finger was involved in 36 (29.5%) subjects, followed by the thumb (n = 31 [25.4%]). Laceration (n = 155 [88.5%]) was the most common injury pattern. The subjects' mean ISS and mean MHISS were 8.52 and 45, respectively.

Conclusion

PCSRI is associated with moderate-to-severe HIs that are most common in occupational settings. Young male carpenters involved in wood and plywood work are more prone to injuries.

Influence of communication determinants on safety commitment in a high-risk workplace: a systematic literature review of four communication dimensions

Health, safety, and environment (HSE) are critical aspects of any industry, particularly in high-risk environments, such as the oil and gas industry. Continuous accident reports indicate the requirement for the effective implementation of safety rules, regulations, and practices. This systematic literature review examines the relationship between safety communication and safety commitment in high-risk workplaces, specifically focusing on the oil and gas industry. The review comprises 1,439 articles from 2004 to 2023, retrieved from the Scopus and Web of Science databases following the PRISMA comprehensive guidelines. This study considers safety communication, communication climate, and communication satisfaction to evaluate their influence on safety commitment under occupational health and safety. This study identifies safety commitment issues and their underlying factors, discussing measures for preventing and reducing accidents and incidents and highlighting preventive measures for future research. It also signifies the variables influencing accident and incident rates. The research underscores the importance of communication dimensions and the need for workers to possess adequate skills, knowledge, and attitudes regarding occupational safety and health procedures. Moreover, the study contributes to the industrial and academic domains by improving organizational safety commitment, promoting a safety culture, and developing effective communication strategies. Furthermore, practitioners may benefit from this comprehensive overview in developing, evaluating, and enhancing occupational safety.

Building Construction Artisans’ Level of Access to Personal Protective Equipment (PPE) and the Perceived Barriers and Motivating Factors of Adherence to Its Use

Background

Employers are required to supply personal protective equipment (PPE) to all employees in Ghana, and employees are required to wear the PPE provided. In Ghana, previous studies on health and safety in the construction industry that touched on PPE use did not explicitly demonstrate the reasons why many workers choose to use or not to use it, though they may be at risk of occupational hazards. The purpose of this study was to determine building construction artisans' level of access to PPE and the perceived barriers and motivating factors of adherence to its use. The contribution of this study lies in its examination of the perceived barriers and motivating factors underlying adherence and nonadherence to PPE use in the construction industry, particularly building construction, which is yet to be determined in Ghana.

Method

Data was collected from 173 frontline building construction workers using a structured questionnaire. The data was analyzed using a two-way multivariate analysis of variance (MANOVA) and one-way analysis of variance (ANOVA) to examine the effects of demographic variables on the perceived barrier and motivating factors of adherence to PPE use.

Results

The most common PPE that participants had access to was safety boots/shoes, with their main source being borrowing from colleagues. The majority of participants disagreed with the perceived barriers while agreeing with the motivating factors of adherence to PPE use. The results suggest statistically significant differences for years of working experience (Wilks = 0.77, F = 2.47; p ≤ 0.01) and form of employment (Wilks = 0.72, F = 3.25, p ≤ 0.01) for perceived barriers to adherence. For perceived motivating factors to adherence, significant differences were obtained for age group (Wilks = 0.84, F = 2.42, p ≤ 0.01), years of experience (Wilks = 0.85, F = 2.35, p ≤ 0.01), and form of employment (Wilks = 0.71, F = 5.22, p ≤ 0.01).

Conclusion

Age groups, years of experience, and form of employment were the main factors mediating adherence and nonadherence to PPE use by the construction workers. This study recommends safety training for workers if good safety management and performance concerning PPE use are to be achieved.

Differences in Workplace Risk Perception between Foreign-Born and First-Generation Mexican American Construction Workers

Risk perception is used to quantify risks in the industry and is influenced by different socio-demographic variables. This work aims to determine significant differences in the risk perception between Mexican American migrants and first-generation Mexican American construction workers. This study used a sample of 112 construction workers. A guided questionnaire was applied to collect socio-demographic information. For workplace risk behaviors, we used a 21-item questionnaire adapted from the previous instrument. Each question asked the participant's perception of the frequency with which they carried out risky activities during routine work activities and the severity of the possible injuries, using a five-level Likert scale. Then, an inferential analysis was carried out using analysis of variance (ANOVA). The main results highlight that time of residence in the United States had a significant influence (p = 0.012) on risk perception in the surveyed construction workers. On the other hand, the age and time they have been working for the organization did not significantly influence risk perception. Finally, risk perception can vary in construction workers according to different variables. It is essential to investigate the factors that influence it, to prevent risky behaviors that can lead to accidents.
