危险与可操作分析（HAZOP）方法作为定性的危害分析方法，难以实现残余风险的量化，在此基础上引入安全完整性等级（SIL ）分析技术，并对以下内容进行了简介：安全仪表系统（SIS ）、SIL ，以及SIL分析的两个步骤，即SIL定级和SIL验算；SIL定级的3种方法，如风险矩阵、风险图和保护层分析（LOPA）方法；开展SIL验算工作的重点；选取在役装置的一个联锁系统，以实例方式简单介绍了开展SIL定级和SIL验算的过程，并对最终结果进行分析。最后，对开展SIL分析工作的注意事项进行了简单梳理。

Hazard and operability analysis (HAZOP ) method , as a qualitative hazard analysis method ,is difficult to quantify the residual risk .On the basis of that ,safety integrity level (SIL) a‐nalysis techniques are introduced and briefly described ,w hich include the safety instrumented system (SIS) ,SIL ,and the two steps of SIL analysis :SIL classification and SIL verification .Then ,three methods ,such as risk matrix ,risk map and layers of protection analysis (LOPA ) ,of SIL classifica‐tion are introduced ,as well as the key points of SIL verification .Besides ,choosing an interlocking system of in‐service device ,the process of SIL classification and SIL verification are carried out by ex‐amples ,and the final results are analyzed .In the end ,the article combed the precautions of carrying out the SIL analysis .
