Identification and Classification of Risk Factors in Municipal Engineering Based on JHA

Municipal engineering has always been an important part of the construction industry. Due to the lack of research on the classification of risk factors earlier, safety accidents in municipal engineering are not uncommon and have not been effectively contained. This paper introduced the JHA method of risk management theory. It was carried on of the risk identification and classification of the road traffic engineering project and the underground pipeline engineering in the typical municipal engineering. It was found that the risks of the two projects have common points, including unsafe behaviors of personnel, unsafe conditions of machinery and equipment, poor operating conditions, and complex external environments. However, they both have different risk factors. Road traffic projects have more risk points than underground pipeline projects. The former's safety management is stronger than the latter. This implied that the risk factor categories of municipal engineering also need to be further refined.
