    Why conduct a riskassessment

    Human factors save life, stop workplace injures,illnesses and increase staff morale.

    Legal factors meet legislative requirements,OHS&W and WorkCover.

    Financial factors decrease the risk of prosecution

    and fines incurred, lower WorkCoverlevies, reduceabsenteeism, increase potential for gainingshareholders and increase productivity.

    Introduction to HIRARC

    Principles used in workplace to managesafety and health.

    Section 15 (2)(a) of OSHA 1994:which reads the provision andmaintenance of plants and systems of

    Quantitative Risk Assessment

    In cases where hazards are numerousand complex

    eg; Chemical process plantShould have Job Safety Analysis (JSA)- describe job in less than 10 steps

    - List things that can go wrong- eg; Changing a Car Wheel
