This guide helps major hazard facilities (MHF) operators prepare a safety case for their MHF. The regulator will ask for this when the operator applies for an MHF license. 

A safety case is written information about the hazards and risks that could lead to a major incident at an MHF. 

It should show how the operator can control the hazards and risks, or how they will control them. The safety case needs to prove that the controls will allow the facility to operate safely. 

The guide tells operators: 

  • the steps to prepare the safety case  

  • what content needs to be in a safety case 

  • how the safety case can prove that they have done everything possible to reduce hazards and risks. 

This is one of 9 guides to help MHF operators understand Chapter 9 – Major hazard facilities in the model WHS Regulations.
