摘　　要：以荷兰应用科学院(TNO)基于网格法的毒性气体个人风险定量计算为基础,介绍个人风险计算网格的划分原则,失效事件的选取,气象等级和风向的联合分布概率、引发事件发生频率的确定方法,死亡概率的计算模型和个人风险值的计算步骤。以煤气管道发生CO泄漏为实例,进行个人风险计算。Based on the quantitative calculation of personal risk of toxic gases based on grid method by the Netherlands Academy of Applied Sciences (TNO),the dividing principle of the grid of personal risk calculation,the selection of failure events,and the methods for determining the joint distribution probability of meteorological grade and wind direction and the frequency of events are introduced. The calculation model of death probability and the calculation steps of personal risk value are also introduced. Taking the CO leakage of gas pipeline as an example,the personal risk calculation is carried out.
