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.

Occupational noise exposure and health impacts among fish harvesters: a systematic review.

BACKGROUND: Occupational noise exposure has been identified as a significant risk factor for fish harvesters. Chronic noise exposure causes hearing and other health problems and undermines the quality of life and well-being. This review paper aims to highlight noise-related auditory and non-auditory health effects among fish harvesters. MATERIALS AND METHODS: A systematic literature search approach was adopted using the following databases: PubMed, Embase, SCOPUS, Web of Science, Google Scholar, and by exploring grey literature. The literature search was conducted in 2020 (between October 15 and November 30). Relevant articles were explored by reviewing title, keywords, and abstract based on the inclusion and exclusion criteria. The full-text critical review of selected papers was made and finalized the most relevant studies. RESULTS: Initial 1,281 records were identified, exploring various databases and additional sources using relevant keywords. Duplicate articles were removed and retrieved 746 articles. After that, a screening of 746 research papers was done based on the selection criteria and finalised 28 articles for full-text review. Finally, articles were filtered based on the study's aim and extracted 17 papers for the final review. CONCLUSIONS: Noise-induced hearing loss was considered a significant health risk to fish harvesters across the studies, affecting physical and emotional well-being. The prevalence of hearing loss was observed from 6% to 80%. Other health problems, such as headache, dizziness, annoyance, stress, fatigue, elevated blood pressure, sleep disturbances, and impaired cognitive performance, were also reported. Further research is needed to validate the non-auditory health effects among fish harvesters.
