Who enforces COMAH
Control of Major Accident Hazards regulation 2015 is enforced in Great Britain by the COMAH competent authority (CA). This comprises five public bodies working in partnership;
- Environment Agency (EA)
- Scottish Environmental Protection Agency (SEPA)
- Natural Resources Wales (NRW)
- Health & Safety Executive (HSE)
- Office for Nuclear Regulation (ONR)
This Regulations implement the Seveso III Directive (2012/18/EU).
Where does this regulation apply
It applies when a site has more than a threshold quantity of dangerous substances present (Lower Tier). Sites are subject to more stringent controls if the quantities of substances present are above a higher threshold (Top Tier). Lower tier sites are required to prepare a Major Accident Prevention Policy while top tier sites prepare the more detailed Safety Report.
This regulation was a response to a serious industrial accident which occurred on 10th July 1976 in the town of Seveso in the Lombardy region of Italy where 1kg of 2, 3, 7, 8-tetrachlorodi-benzo-p-dioxin (TCDD) into the environment. This accident resulted to:
- Dead of over 3,000 animals
- 80,000 more slaughtered to prevent the dioxin entering the food chain.
- Approximately 500 cases of the skin disease chloracne reported.
- Financial cost rose to about $150 million.
The result of this accident led to the Seveso III Directive which led to the “Control of Major Accident Hazards Regulations”.
The course covers all aspects of the COMAH Regulations, including information on creating a Major Accident Prevention Policy (MAPP), and provides learners with an understanding of their responsibilities under the latest Seveso III Directive which applies to all COMAH establishments from 1st June 2015.
