Occupational Health and Safety Risk Analysis with The Fault Tree Analysis Method

Abstract

Construction projects are often the most significant contributor to workplace accidents. Many things can happen during construction activities that can cause work accidents. This research aims to identify hazards, find the highest risk that can occur, and determine the primary event using the Fault Tree Analysis Method at Abdurrahman Saleh Air Force Hospital in Malang Regency. This research uses qualitative methods with data collection using questionnaires, interviews, and observations. The questionnaire was distributed to 12 selected respondents based on recommendations from the QHSE Officer. The results of the study were physical, chemical, and psychological hazards. There are 12 low-risk category variables, nine medium-risk, and two high-risk variables. The highest risk variables occurred in the production of rebar & fabrication and plastering work; workers were exposed to electric shock when cutting iron due to high voltage and falling from a height during outdoor plastering work. Basic events are lack of coordination, lack of enthusiasm, lack of motivation, lack of skills, lack of work experience, joking, lack of concentration, fatigue, rushing, lack of OHS members, limited monitoring time, messy work environment, lack of lighting, little workspace, extreme weather, slippery footing, high voltage electricity, tools/machines not functioning correctly, no warning, lack of safety equipment, limited PPE, and workers are not comfortable using PPE
