EEMUA 191: Alarm systems - a guide to design, management and procurement

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. Developed by users of alarm systems with input from the GB Health and Safety Executive, EEMUA 191 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.
