The Control of Major Accident Hazards (COMAH) Regulations 2015 and registration requirements came into effect on 1 June 2015. COMAH are the enforcing regulations within the United Kingdom of the Seveso II Directive devised in Brussels following the Seveso disaster.
They are applicable to any establishment storing or otherwise handling large quantities of industrial chemicals of a hazardous nature. Types of establishments required to register include chemical warehousing, chemical production facilities and some distributors. The principal aim of the regulations is to reduce the risks of potential major accidents, such as the Flixborough disaster, that are associated with the handling of hazardous substances.
COMAH regulations operate on two hazard levels based on each establishment's inventory and associated risk status; 'Lower Tier’ and 'Upper Tier'. Tier level is indicated in the dataset along with each establishments geocode (x,y and latitude longitude geo-reference).
