The Health and Safety Executive (HSE) has statutory responsibilities in the regulation of onshore major hazards, some of which are delivered by the Major Hazards Risk Assessment Unit, within our Chemical Explosives and Microbiological Hazards Division (CEMHD). The Unit’s responsibilities include:
• Contributing to the regulation of onshore major hazard sites, with a focus on assessing major hazard risks;
• Working with other parts of Government, including in Scotland and Wales, to deliver statutory advice on development around existing major hazard installations and major accident hazard pipelines to local authorities, duty holders, developers and the public at large; and
• Providing statutory advice on plans to develop new businesses holding significant quantities of flammable or toxic substances.
Maintaining public safety assurance in the land use planning system in relation to major hazards is central to the activities of the unit. Our advice helps to prevent major accidents, and if they were to occur to mitigate the consequences. The Unit undertakes these statutory activities on over 3000 major hazard onshore installations (including pipelines) under the following provisions:
• Hazardous Substances Consents (HSC) Regulations 2015, which relate to considering whether the presence of a significant quantity of hazardous substance is acceptable in a given location;
• Control of Major Accident Hazard Regulations 2015 (COMAH); and
• The Town and Country Planning (Development Management Procedure) (England) Order 2015, which covers development control around major hazard sites.
