Occupational Exposure on Board Fishing Vessels: Risk Assessments of Biomechanical Overload, Noise and Vibrations among Worker on Fishing Vessels in Southern Italy

Investigating the Relationship Between Environmental and Cognitive Ergonomics with Work-Related Musculoskeletal Disorders: A Case Study in an Automobile Industry

BACKGROUND

Cognitive and environmental parameters are among the most important influencing factors in the prevalence of WRMSDs, which have been studied less compared to physical ergonomic in automobile industry.

OBJECTIVE

This study was conducted with the aim of investigating the relationship between environmental and cognitive ergonomics with the prevalence of WRMSDs in an automotive industry.

METHODS

This study was conducted in 2023 in an automobile company. The sample size was 740 workers. The prevalence of WRMSDs was assessed using the Cornell Musculoskeletal Discomfort Questionnaire. Occupational stress, mental workload, sleep quality, and cognitive failure were assessed by Job Content Questionnaire, NASA-TLX Questionnaire, Pittsburgh Sleep Quality Index, and Cognitive Failure Questionnaire, respectively. Noise were measured by KIMO-DB300 sound analyzer. The intensity of lighting was measured using a Hanger Screen Master illuminance meter. Heat stress was measured by Wet Bulb Globe Temperature (WBGT).

RESULTS

72.58% reported the musculoskeletal disorders in at least one of their body parts during the past 12 months. The average values of occupational stress, mental workload, sleep quality, and cognitive failure among workers with WRMSDs were higher than the participants without WRMSDs (p-value < 0.05). There was a significant difference between the values of all studied physical harmful factors between the two investigated groups, except thermal stress (p-value < 0.05).

CONCLUSION

Findings from this study highlight the critical need for a holistic approach that considers both the external work environment and internal cognitive processes to effectively prevent and manage WRMSDs among automobile industry workers.

Occupational noise exposure at sea: A socio-legal study on fish harvesters' perceptions in Newfoundland and Labrador, Canada

Introduction

Noise is a significant health hazard for fish harvesters. Chronic exposure to hazardous noise levels of 85 dB (A) for an 8-h work shift can have adverse health impacts, including both auditory and non-auditory health problems such as noise-induced hearing loss, stress, hypertension, sleeping disorders, and impaired cognitive performance.

Methods

A review of legislation and policies governing workplace noise exposure, as well as qualitative, semi-structured interviews, were conducted to assess how fish harvesters in Newfoundland and Labrador (NL) manage onboard occupational noise exposure and perceive noise-induced health problems, as well as the barriers and challenges associated with preventing and controlling noise exposure.

Results

The legal review shows no compulsory noise preventive measure at the fishing vessel design stage in Canada. Limited implementation of Occupational Health and Safety (OHS) regulations to control and prevent onboard noise by employers in Newfoundland and Labrador. Fishers reported that their workplace is noisy. Over time, fish harvesters adapted to the environment and learned to tolerate loud noise, displaying fatalistic behavior. Fish harvesters reported avoiding using hearing protection onboard due to navigation safety concerns. Fishers reported hearing loss as well as other non-auditory health problems. Inadequate noise control measures adopted by employers, a limited supply of hearing protection onboard, and a lack of regular hearing testing, training, and education were identified as the main barriers to preventing and controlling noise exposure.

Conclusion

Proper implementation of NL OHS regulations and the development of hearing conservation initiatives by employers are necessary. All stakeholders, including the federal and provincial governments, WorkplaceNL, and not-for-profit fishing organizations in the province, are strongly recommended to initiate training and education campaigns to help fish harvesters understand noise exposure and adopt preventive measures.

Epidemiology of occupational hazards and injuries among fishermen at Tanji fishing site in The Gambia: an analytical cross-sectional study design

Fishing is a well-known industry, and there are certain risks of work-related diseases and accidents, occupational hazards and safety issues. This study aimed at examining the determinants of occupational hazards and injuries among fishermen at Tanji fishing site, a major fish-landing site in the Gambia, West Africa. An analytical cross-sectional design was conducted in August to October 2019. Structured questionnaires were administered to fishermen at Tanji fishing site. A simple random sampling method was used to select fishermen in this study. Data entry and processing for preliminary data analysis was done using Stata version 15. Descriptive and bivariate analysis using chi-square/fisher exact test as well as binary logistics regression analysis were used. The adjusted risk ratios (aRRs) and confidence intervals of 95% were calculated. A P-value < .05 was considered for statistical significance. The proportion of occupational hazards were 95%, while reported injuries were 85%. Ergonomics, physical, and environmental/climatic hazards formed the majority at 25%, 23%, and, 21%, while muscle strains and falling formed the majority for types of injuries at 19% and 17%, respectively. Fishermen who used PPE (aRR: 0.12and 95% CI: 0.01-0.99) were less likely to have occupational hazards relative to those who did not use PPE. In terms of injuries, fishermen who were smokers (aRR: 3.18, 95% CI: 1.32-7.66), had chemical hazards (aRR: 3.14, 95% CI: 1.26-7.86) and had no fishing safety rules (aRR: 2.81, 95% CI: 1.15-6.85) were more likely to sustained injuries relative to other categories after controlling for confounders. This research found a high prevalence of OSH hazards and injuries among fishermen, highlighting the critical nature of strengthening safety regulatory services for this workforce.

Seafarers' Perception and Attitudes towards Noise Emission on Board Ships

Noise has long been neglected as an environmental pollutant and impairment health factor in maritime transport. Recently, acoustic pollution indicates the highest growth in transport external cost unit values. In 2020, questionnaires were submitted to seafarers to examine their noise exposure and perception on board and attitudes towards noise abatement measures. Responses of 189 participants were processed using descriptive statistics and Likert scale valuation, while their consistency was tested with indirect indicators using linear regression and correlation test. Results show that more than 40% of respondents do not consider noise as a significant environmental problem. The negative perception among respondents with ≥10 years of work experience was much lower (23.53%). Most are aware of the onboard noise harmful effects that can influence their health. Despite that, they use personal protection equipment only sometimes. A higher positive perception was recorded in groups of respondents with a university degree (90%), work experience longer than ten years (82.35%), and monthly income higher than 4000 € (70%). Respondents are not strongly motivated to participate in funding noise mitigation measures, and such a viewpoint is not related to their monthly incomes. The low awareness and motivation regarding acoustic pollution generally shown by the surveyed seafarers should be watched as a threat by the company managers. Better education and awareness are likely to be crucial to change the current state of affairs.

Analysis of Metrological Requirements in Occupational Health and Safety Regulations Related to the Emerging Risk of Exposure to Vibrations

In occupational exposure to vibration, the risk assessment process is defined through a regulatory framework that presents some relevant metrological problems. This framework considers methods based on estimation and on measurements. Estimation methods could employ existing information that is provided for each manufacturer to each individual tool or application to carry out such estimation. The use of estimation methods has some problems, such as substantial uncertainty. When using measurement methods, some metrological aspects are not fully defined. Therefore, a new and emerging risk appears due to certain methodologic limitations. Consequently, the variation between the estimated and the actual values could overestimate the level of occupational exposure to vibrations. Thus, with this paper, a critical analysis of this emerging metrological problem is provided. For this, a critical analysis of the metrological requirements regarding European standards is developed. To this end, the estimation method and measure method are investigated, considering, in both cases, the main factors related to uncertainty, reliability, and traceability. With this structure, a set of metrological limitations have been identified, thus pointing towards future lines of research that allow the improvement of the process of assessing the level of occupational exposure to vibrations.
