Risk assessment of health, safety and environmental (HSE) hazards based on system life cycle in an aquaculture industry, Hormozgan province

This study aimed to assess the risk of health, safety, and environmental (HSE) hazards based on the system's life cycle using Fuzzy Failure Mode and Effects Analysis (FFMEA) in an aquaculture industry in Hormozgan province.

Materials and Methods:

Identification of HSE hazards by system life cycle stage, including (1) construction and preparation of pools, (2) construction of feed production and preparation plant, (3) pumping and filling the pools, (4) maintenance and breeding of aquatic animals and (5) catching and transporting the aquatic animals was carried out by five HSE experts using the FMEA worksheet. Then, the risk of identified hazards was assessed by the FFMEA method (with the range of risk priority number [RPN] of 1-634). All the ethical issues were considered in this study.

In the life cycle of the aquaculture industry, a total of 343 HSE hazards were identified, of which 38.8% had high risk, 44.6% had medium risk, and 16.6% had low risk. About 86% of the HSE hazards were in the health and safety field and 14% of them were in the field of environment. The construction of feed production and preparation plant (having 46% of the HSE hazards) was determined to be the most hazardous phase of the life cycle of aquaculture.

The FFMEA risk assessment method based on the life cycle by taking into account the uncertainty in the risk components and identifying and prioritizing the HSE hazards in the entire life stages of a system can be used as an efficient and effective tool for assessing the risk of HSE hazards in different industries.
