基于事故发展与控制的隐患分级方法

为使隐患管理工作更加科学,对隐患与事故的关系进行研讨,提出隐患的根本属性是能够促使事故发生或发展。通过预估促使和控制(阻碍)事故发展的因素,来揭示隐患在事故过程中的作用机制。根据发生作用的时间将隐患分为第1类隐患和第2类隐患。在风险评估过程中,解决了具体隐患风险分级的问题,提出隐患暴露频率、其他条件的可能性、隐患纠正系数、事故后果初始分值、人员防护修正系数、人员暴露修正系数、应急处理与事故控制修正系数和财产损失修正系数等评价指标。通过隐患致因事故风险的计算,评估隐患的最终风险。

Risk Classification Method for Accident Potential Based on Development and Control Measures of Accident

For the purpose of making the management of accident potential more scientific,the relationship between accident potential and accident was discussed and studied.The fundamental property of accident potential was brought forward that it can make the accident happen or develop.The mechanism whereby accident potential functions in the accident was revealed clearly,by predicting the impelling and inhibiting factors in the accident process.The accident potential was classified into two types(the first type of accident potential and the second type of accident potential) according to the different time they work.In the risk assessment,the problem of specific accident potential grading was resolved.By introducing the assessment indexes of accident potential exposure frequency,possibility of other factors,corrective actions,the initial value of the consequences of the accident,the correction factor of personnel protection,the correction factor of personnel exposure,the correction factor of emergency measures,the correction factor of property loss,an assessment index system was established.By calculating the risk of accident potential-causing accident,the real risk of accident potential was assessed.
