This Delivery Guide (DG) is part of the COMAH Competent Authority’s (CA)
strategy for encouraging strong leadership and preventing major accidents
in major hazard industries. It underpins the CA’s programme for ensuring
effective major hazard leadership in preventing, controlling and mitigating
major accidents.
- The guide covers the background and arrangements for inspection and
investigation of leadership. A separate Major Hazard Leadership
Intervention Tool provides the principles to use when engaging with senior
leaders. - This guidance sets out a framework for:
a) inspecting aspects of major hazard leadership (MHL) at senior
levels in companies; and
b) investigating leadership failures at senior levels following a major
accident.
