Evaluation of OHS practices based on work accident risk analysis using HIRA, FTA, and WISE methods (Case study: Plastic recycling business X)

Abstract

The lack of OHS implementation is particularly notable in Small and Medium Industries (SMI), primarily due to limited knowledge and motivation concerning OHS application in their work systems. SME X, a plastic recycling business, has experienced several work accidents and necessitated hazard identification and OHS implementation for hazards with high and extreme risks. The HIRA method was employed to assess the extent of risk posed by various types of hazards. After identifying these hazards, the root causes of high and extreme-risk hazards were determined using FTA. Subsequently, measures were taken to mitigate the risks associated with high and extreme-risk hazards through WISE. The results revealed 28 potential hazards, with improvements focused on six high and extreme-risk categories. Proposed WISE interventions include the provision of Personal Protective Equipment (PPE), the use of ramps, the utilization of wheeled aids, and other enhancements to techniques and methods at each workstation.
