COMAH - Demystifying COMAH - A Basic Introduction


This course is about the principles behind the Control of Major Accident Hazards Regulations 2015 (COMAH) and the duties the regulations impose.  It has been designed to provide duty-holders with an understanding of COMAH and in doing so it removes the veil of mystery that at times appears to shroud these regulations.  This course identifies the COMAH duties for Lower and Upper Tier establishments and what needs to be done to comply with them. It also explains the duties that fall to the Competent Authority (CA) and Local Government. The course introduces the concept of 'compliant demonstration' and provides an overview of what the COMAH Competent Authority is looking for.  It will also explain the remodelled COMAH regulatory regime and the national strategic inspection topics.  The course is particularly targeted at lower tier COMAH operators but will also provide valuable background for upper tier operators.

The course will cover:

  • An introduction to major accident hazards and the major hazards regulatory regime
  • COMAH application, including the aggregation rules, duties and notification to the CA
  • The Major Accident Prevention Policy, what it should and should not contain
  • Understanding your risk profile
  • Controlling your risks
  • Roles and responsibilities for compliance
  • What to expect from inspections
  • COMAH guidance and sources of information

Who should attend?

Managers, supervisors and safety professionals who have responsibilities within companies for managing or implementing major accident controls at existing establishments who want to  refresh their understanding of COMAH. It is also suitable for managers/supervisors of establishments newly brought within scope of COMAH 2015 who may be involved in dealing with the COMAH Competent Authority during inspections.
