Unit Descriptor

Unit descriptor 

This unit describes the performance outcomes, skills and knowledge required to conduct a formal risk assessment comprising analysis and evaluation of occupational health and safety (OHS) risk. It has been designed to be consistent with the Australian Standard, AS/NZS 4360: 2004 Risk management.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement.

Application of the Unit

Application of the unit 

This unit addresses the knowledge, processes and techniques necessary to analyse and evaluate OHS risk as part of the risk management process.

OHS risk analysis involves defining the range of consequences, assessing the effectiveness of existing controls and deciding the likelihood of each consequence, and combining these in some way to obtain a level of risk. Risk evaluation is the comparison of pre established criteria for tolerance and the subsequent ranking of risks requiring control.

The situation to be analysed and evaluated may involve a single task or a process comprising a series of tasks.

Application of this unit must be consistent with the pertinent sections of the Australian Standard, AS/NZS 4360: 2004 Risk management.

Licensing/Regulatory Information

Not applicable.
