EEMUA Publication 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.

  • Providing clear guidance for both existing and new alarm systems
  • Written by alarm systems experts working on high hazard sites
  • Informed by real-world process safety experiences
  • Acknowledged as good practice by leading regulators
  • Aligned with international standards
  • Contributing to plant safety, efficiency and compliance
  • Globally applicable across a wide range of industry sectors


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.

EEMUA Publication 201 Control rooms: a guide to their specification, design, commissioning and operation

This third edition of EEMUA 201 was produced in response to changes in technology and good practice across industry. EEMUA 201 provides a comprehensive guide to the design of control rooms including the control building, physical aspects of the control room, working environment, console design, and control system graphics. Emerging issues are covered such as devices used outside of the control room, security and there is a stronger focus on human factors. The aim of the new edition is to provide improved guidance to people involved in the design of control rooms, both during new-build and modification projects as well as evaluating existing control rooms.

EEMUA 201 relates to human-computer interface (HCI) systems provided for people operating industrial processes and activities on facilities such as chemical plant, power stations and oil refineries. HCI systems are one of a number of key areas that can influence – and optimise – human performance in the area of a centralised control room, so important in maintaining process and major hazard safety.

EEMUA 201 gives guidance on: the factors to take into account when designing an HCI; display hierarchies; screen display format design; and control room design attributes which affect HCIs. It is for use by engineers and managers in both user and contracting organisations. The objective is not only to make plants more operable, efficient and able to avoid abnormal situations, but to be able to better manage such situations should they occur.

EEMUA 201 is not a standard and is not intended to replace any. Designers will be expected to identify and adhere to any standards and regulations and any company and project specifications. The intention is that EEMUA 201 will provide guidance on how this can be achieved in the most effective way.
