从发生事故的可能性、暴露于危险环境的频繁程度、事故产生的后果三方面分析了桥梁防腐蚀施工作业条件的3个危险性因素,介绍了危险性分值与危险程度的关系,通过对危险源的辨识和评价,确定重大危险源,并对重大危险源采取适当的控制方案,以将危险性降到最低。
The three risk factors of bridge anti-corrosion construction operation conditions are analyzed from the probability of accidents, the frequency of exposure to dangerous environment and the consequences of accidents. The relationship between the risk scores and the degree of danger is introduced. Identification and evaluation of hazards, identification of major hazards and appropriate control of major hazards to minimize risks.
