Due to the number of serious Process Safety incidents that have occurred from the implementation of the Process Safety Management Standard, US Occupational Safety and Health Administration has implemented National Emphasis Programs to audit process safety compliance at refineries and chemical processing plants. Both the Refinery and the Chemical National Emphasis programs identified Mechanical Integrity as the element with the largest number of compliance gaps. An overview of the techniques used to identify the scope of an Asset Integrity System will be provided. Learning from incidents, including outside the Chemical Processing Industry, that have occurred will be reviewed to illustrate the importance of smaller, often overlooked, items that became root causes of incidents. The goal of this paper is to provide the reader with guidance on identification, determination of inspection frequency, documentation and deficiency resolution of critical equipment that not only satisfies the regulatory requirements but also includes all items, including small, often overlooked items.

没有什么是永恒的：预防性维护系统中缺少的项目

由于实施过程安全管理标准发生了许多严重的过程安全事故，美国职业安全与健康管理局实施了国家重点计划，以审核炼油厂和化学加工厂的过程安全合规性。炼油厂和化工国家重点计划都将机械完整性确定为合规差距最大的要素。将提供用于识别资产完整性系统范围的技术的概述。将审查已发生的事件，包括化学加工行业以外的事件，以说明成为事件根本原因的较小但经常被忽视的项目的重要性。
