COMAH Public Information Northern Ireland

The Public information relates to operational establishments which are subject to the 2015 Regulations because certain dangerous substances are present at or above the qualifying thresholds in the Regulations.

The information tells you about the type of business and the controls in place to minimise the likelihood of a major accident. You may take reassurance from the fact that many COMAH establishments have existed for a number of years and their operators understand the requirements placed on them to operate safely.

Although the substances used or stored at COMAH establishments can be dangerous, the establishments are strictly regulated under the COMAH Regulations 2015 and have to manage their activities in a way which reduce risks to workers and the public. Operators must take all measures necessary to prevent major accidents and to limit their consequences for people and the environment. This is achieved through appropriate plant design, process control, mitigation measures and emergency procedures.

In Northern Ireland the regulations are enforced by the Competent Authority which comprises jointly the Health and Safety Executive Northern Ireland (HSENI) and the Northern Ireland Environment Agency (NIEA).

There are two types (tiers) of establishment which are subject to COMAH, known as ‘Upper Tier’ and ‘Lower Tier’ depending on the quantity of dangerous substances they hold. Upper Tier establishments will hold greater quantities of dangerous substances meaning that additional requirements are placed on them by the Regulations.
