Control of Major Accident Hazard (COMAH) Regulations
The Control of Major Accident Hazard (COMAH) Regulations applies mainly to the chemical industry, but also to some storage activities, explosives, nuclear sites and other industries where the threshold for quantities of dangerous substances identified in the Regulations are stored or used.
To ensure the safety of the community, Cheshire West and Chester Council, as the Local Authority, has a statutory duty to write and test an external plan for sites covered by these Regulations.
To ensure the community are aware what actions to take in the event of a major accident on the site, a safety letter and information is sent out every 5 years to the community around the site. This is known as the Public Information Zone (PIZ).
