The Control of Major Accident Hazards (COMAH) Regulations 2015 came into effect on 1 June 2015 and replace the 1999 COMAH Regulations which have been revoked. The HSE has also published new guidance on the COMAH Regulations 2015 (L111, Third edition) which applies from 1 June 2015. 

The 2015 Regulations contain some new or changed duties including:

  • the list of substances covered by the Regulations has been updated and aligned to the CLP Regulation (Classification, Labelling and Packaging)
  • some definitions have been changed
  • there are transition arrangements for safety reports
  • for emergency planning, there is a new requirement for co-operation by designated authorities (Category 1 responders, as defined in the Civil Contingencies Act 2004) in tests of the external emergency plan
  • stronger requirements for public information including a duty for lower-tier establishments to provide public information. There are provisions for electronic access to up-to-date public information
  • the domino effects duty is broader, including a duty for members of a domino group to co-operate with neighbouring sites to share relevant information
  • stronger requirements for the competent authority on inspection
  • local authorities must now inform people likely to be affected following a major accident.
  • The Guidance can be found on the HSE website.
