Analysis of Health and Safety Risk using HIRARC and FTA Methods on Finishing Machines at PT. XYZ

Abstract

This research is motivated by the numerous risks of work accidents that occur in the finishing unit 1 of PT. XYZ. Without adequate evaluation, potential hazards in the work environment are not identified, so workers are at risk of experiencing other work accidents. The purpose of this study is to identify potential hazards in line 1 machines, conduct risk assessments by considering the likelihood and consequences scale, determine the root causes of the highest risks, and formulate control recommendations. The Hazard Identification, Risk Assessment, and Risk Control method is used to identify hazards, assess risk levels, and formulate appropriate risk controls. The HIRARC method is supported by the use of a second method, namely Fault Tree Analysis (FTA), to determine the root causes of the highest risks, thereby enabling a deeper understanding of the causes of these risks. Data collection was carried out through observation, interviews, and distributing questionnaires to 16 production operators in shift A. The results show that there were 64 hazard risks in 6 finishing machines. In the 15 HIGH category hazard risks, FTA processing was carried out, indicating 81 root risks. Control recommendations were made using a hierarchy of control with administrative, engineering, and PPE efforts.
