Risk assessment for occupational health and safety of Soekarno-Hatta international airport accessibility project through HIRARC method

Abstract

Statistic based on BPJS data in 2019 have shown that the number of work accident recorded 77.295 cases and the construction sector is still the highest contributor to work accident cases in comparison to other sectors. Soekarno-Hatta International Airport accessibility project connects the northern perimeter road with the southern perimeter road with a total length of 4 km. This study focuses on the flyover construction, considering that is the highest risk on construction activities. Risk assessment tool on this research using HIRARC method. In general, there are three major steps of HIRARC; hazard identification, risk assessment and risk control. Identifying hazard is a process to determine the risks of hazards that occure in construction work. Assessing risk of construction work calculated using likelihood and severity index. Then, the result of hazard identification and risk assessment, risk control are taken to mitigate the hazard risk. This study instrument used interviews and observations both used risk assessment sheet which filled by safety officers, safety supervisors, site engineers and site supervisors. There were 45 hazards identified for five construction work which are, (i) survey (ii) land clearing, (iii) excavation work, (iv) pilling work, and (v) bored pile work. The conclusion that can be drawn is that there are seven extreme risk at this project, i.e. (i) Workers fall into lake; (ii) Workers get hit by road users; (iii) The operator is exhausted; (iv) Crane wire rope failure; (v) Vibro hummer failure; (vi) Workers pinched by bracket formwork and (vii)Workers injured by pieces concrete pile cutting.
