What is a Principal Hazard?
- Something that has the potential to result in multiple deaths in a single incident or a series of recurring incidents.
WHS MP Reg Cl4 Definition,
* An activity, process, procedure, plant, structure, substance or situation relating to the carrying out of mining operations that have the reasonable potential to result in multiple deaths in a single incident or series of recurring incidents.
WHS (MPS) Regs Section 27 - Identification of Principal Hazards and Conduct of Risk Assessments
WHS (MPS) Regs Section 27 - Identification of Principal Hazards and Conduct of Risk Assessments
* Must identify all principal hazards
* Must carry out a risk assessment for all identified PH’s
