Under the Control of Major Accident Hazards (COMAH) Regulations 2015, operators are required to demonstrate that all major accident hazards (MAHs) have been identified. MAH identification is commonly carried out against a list of guidewords, or deviations, intended to identify all potential initiators of MAHs at an establishment.
Included in these guidewords are often a smaller number of environmental initiators, capturing extremes of temperature and weather. However, assessment is typically conducted on current weather patterns, on equipment often designed to older standards. Details here.
