Hazard and Risk Analysis Using Hirarc and Hazop Methods on Erection Girder Work

Abstract

Superstructure work of the toll flyover construction is one of the works that have a high level of risk, especially when the erection girder work passes over the existing toll road. This study aims to identify hazards on erection girder work using the HIRARC and HAZOP methods. Using these two methods requires the implementation of questionnaire and surveying, using at least 30 respondents with 34 respondents is successfully gathered. The results showed that there were 36 possible hazards where 11 hazards were identified as moderate risk and 25 hazards identified as low risk. Then an interview was conducted with occupational health and safety (OHS) experts on site to validate the results of this research. Efforts are being made to carry out inspections of heavy equipment before use, only operators who have SIO that are appropriate and competent to do, conduct toolbox meetings, install warning signs, use PPE, and coordinate and cooperate with existing toll owners.
