摘　　要：功能安全评估是石油、化工、电力、冶金等高危生产行业使用较多的开展保障安全生产的技术分析方法之一,评估过程包含多个环节,应用在装置全生命周期的不同阶段,分析的方法、过程、内容、目的及作用也截然不同,且各环节环环相扣,因此如何在正确的阶段给出适应的分析十分关键。本文针对功能安全评估中典型的HAZOP分析、LOPA分析、SRS编制及SIL验证等环节的开展阶段及流程进行综述。Functional safety assessment is one of the technical analysis methods used to ensure safe production in many high-risk production industries such as petroleum,chemical industry,electric power and metallurgy.The assessment process includes multiple links,which are applied in different stages of the whole life cycle of the device.The analysis methods,processes,contents,purposes and functions are also different,and each link is linked.Therefore,how to give an appropriate analysis at the correct stage is very critical.The paper summarizes the development stages and processes of typical HAZOP,LOPA,SRS organization and SIL verification in functional safety assessment.
