Introduction

Purpose

This document addresses the development, design, installation and management of alarm systems for the process industry. Alarm management includes the whole life cycle of the alarm system

Several workflows. This document defines the terms and models for developing alarm systems and proposes effective maintenance of alarm systems throughout their life cycle.

recommended workflow.

This document is derived from ANSI/ISA-18.2-2009, "Management of Alarm Systems in Process Industries" is an International Society of Automation (ISA) standard,

Appropriate reference is also made to other guidance documents developed in the industry. In major process accident investigation reports, ineffective alarm systems are often identified as

factors that cause the accident. The purpose of this document is to provide a set of methods that can improve safety in the process industry.

The terms and practices associated with an effective alarm system are not defined for the first time in this document..1999, Engineering Equipment and Materials Users Association

(EEMUA) released the 191st edition of the publication. Guidelines for Design, Management and Procurement of Alarm Systems..2003, Process Control for Chemical and Pharmaceutical Industries

The Association of Technical Users (NAMUR) has published Worksheet NA102.Alarm Management.

In developing this document, we have tried to align as much as possible with the terminology and practices used in the previous work of these organizations and committees.

This document specifies the relevant requirements for alarm management and alarm systems. It is intended to provide guidance to the following relevant individuals and organisations.

a) manufacture or implement embedded alarm systems;

b) manufacture or implement third party alarm system software;

c) design or install an alarm system;

d) operate and/or maintain alarm systems; and

e) Review or evaluate the performance of the alarm system.
