Companies use metrics to monitor their process safety performance. Process safety metrics may relate to any aspect of a process safety program but many metrics are developed for individual process safety elements, such as process hazard analysis (PHA). Traditional metrics for PHA mostly address aspects of managing PHA studies, such as the timely completion of corrective actions. However, there are other types of metrics that are of interest, specifically those that characterize the level of safety achieved for a process and the level of quality achieved in a study. This article describes the use of such metrics in PHA and provides examples of their use.

过程危害分析的安全和质量指标

公司使用指标来监控其过程安全绩效。过程安全指标可能与过程安全计划的任何方面有关，但许多指标是针对各个过程安全要素开发的，例如过程危害分析 (PHA)。PHA 的传统指标主要涉及管理 PHA 研究的各个方面，例如及时完成纠正措施。然而，还有其他类型的指标值得关注，特别是那些表征过程实现的安全水平和研究中实现的质量水平的指标。本文介绍了 PHA 中此类指标的使用，并提供了使用示例。
