What it contains

This guidance note advises operators of major hazard facilities (MHFs) how to demonstrate that the facility operates safely. It outlines:

  • how to develop a demonstration for a Safety Case
  • which demonstrations to use and when to involve employees and health and safety representatives
  • how MHFs show they have reasonably reduced risks
  • how examples, industry codes and standards are used in demonstrations
  • how a safety management system supports control measures

At the end of this guide, there are examples of the risk criteria used by MHFs nationally and internationally.
