报警系统是大型现代工业设施操作员界面的重要组成部分。它们通过警告操作员需要注意的情况，为操作员提供重要支持，并在预防、控制和减轻异常情况的影响方面发挥重要作用。自1999年首次出版以来，EEMUA 191已成为全球公认的、领先的警报系统各方面良好实践指南。该出版物由报警系统用户根据GB健康与安全执行机构的输入开发，为设计、管理和采购有效的报警系统提供了全面指导。其目的是在工厂建设或报警系统翻新期间帮助改进现有系统和开发新设施。 过程工业报警系统管理的两项国际标准，即国际自动化学会的ISA 18.2和IEC 62682:2015，均与EEMUA 191一致。新版第三版已全面更新，包括在实践中实施警报管理理念的指南；地理分布过程中的应用；以及绩效指标和KPI。EEMUA 191主要关注为操作工业流程的人员提供的报警系统。其中包括化工、发电、油气开采和精炼等行业的报警系统。然而，大部分指南是通用的，经过适当的解释，可以应用于其他部门。 例如，该指南已成功地用作铁路和运输部门、核工业和其他领域培训的基础。

Alarm systems form an essential part of the operator interfaces to large modern industrial facilities. They provide vital support to the operators by warning them of situations that need their attention and have an important role in preventing, controlling and mitigating the effects of abnormal situations. Since it was first published in 1999, EEMUA 191 has become the globally accepted and leading guide to good practice for all aspects of alarm systems.The publication, developed by users of alarm systems with input from the GB Health and Safety Executive, gives comprehensive guidance on designing, managing and procuring an effective alarm system. It is intended to help in improving existing systems and in developing new facilities during plant construction or during alarm system refurbishments. Both of the international standards for the management of alarm systems for the process industries, ISA 18.2 from the International Society of Automation and IEC 62682: 2015, are aligned with EEMUA 191. The new Third Edition has been comprehensively updated and includes guidance on implementing the alarm management philosophy in practice; applications in geographically distributed processes; and performance metrics and KPIs. EEMUA 191 is primarily concerned with alarm systems provided for people operating industrial processes. These include alarm systems in industries such as chemical manufacture, power generation, oil and gas extraction and refining and others. However, much of the guidance is generic and with appropriate interpretation can be applied in other sectors. For example, the guide has been used successfully as a basis for training in the rail and transport sectors, in the nuclear industry, and elsewhere.
