What is a Principal Hazard?
multiple deaths in a single incident or a series of recurring incidents
WHS MPS Cl 27
Identification of Principal Hazards and Conduct of Risk Assessments
The operator must identify all principal hazards
Must carry out a risk assessment for all identified PH’s
Must use a suitable technique to investigate and analyse
Must consider the individual and cumulative risks
WHS MPS Cl 28
Preparation of PHMP’s
The operator must -
Prepare a PHMP for each identified hazard
Must be readily understandable
Must describe the nature and how it relates to other PH’s
Must describe the analysis methods used
Must include latest RA
Must describe all control measures
Describe the arrangements for providing I.T.I
Refer to design, engineering and tech standards
Set out the reasons for adopting/rejecting controls
Must consider matters in Sch1 and any other relevant matters
Must ensure no mining operations take place before plan is in place
WHS MPS Cl 29
Review of PHMP
The operator must -
ensure a PHMP is reviewed and revised if a control measure is revised under WHS Regs Cl 38 or WHS MPS Regs Cl 29
