Background and Objective: The fisheries industry is complex and dangerous in terms of occupational risk due to the large number of active workers, diverse working conditions, and environment. The present study aimed to identify and evaluate the risks, occupational hazards, and injuries caused by them to help improve the safety and health of employees of sturgeon farms.
Materials and Methods: A total of 180 fisheries science engineers and sturgeon farm workers were selected for interviews, and their demographic characteristics were studied in three provinces of Iran: Gorgan, Mazandaran, and Gilan. The identified risks were divided into five categories: physical, chemical, biological, ergonomic, and psychosocial. Moreover, the risks were identified based on the Occupational Safety and Health Administration (OSHA) technique. The assessment of potential occupational risk hazards in sturgeon farms was conducted using the Job Hazard Analysis (JHA) method. Some factors, such as the probability of occurrence, severity, and frequency of exposure to hazardous agents, were evaluated to determine the risk number.
Results: Physical hazards accounted for the highest risk among other hazards in all three provinces. Respiratory issues were the most common injuries caused by chemical hazards for farm workers. Moreover, psychosocial risks were the most frequent (70%) in Golestan Province. The statistical results indicated that there was no significant difference between the identified risks for each risk (P>0.05); however, chemical risks were significantly different from other risks (P<0.05). The highest risk priority number for physical consequences related to slips and falls was 448, while the inhalation of chemical vapors had the highest risk priority number (224) for chemical consequences. Stress was identified as having the highest likelihood of occurrence for psychosocial risks (252), and skin infections had the highest risk probability number (294) for biological hazards.
Conclusion: The present study indicated that aquaculture workers are at increased risk of various occupational injuries in the relevant environments. The results indicated that workers in the sturgeon fishing industry in northern Iran are exposed to physical, biological, and chemical hazards, with physical injuries being the most prevalent. Slips and falls were among the physical consequences, while lower back pain and shoulder pain represented the most significant ergonomic consequences. Therefore, identifying and raising awareness among workers regarding occupational hazards is essential for their health and safety.
