  1. A) HAZARD GROUPS



    Ø Physical

    Ø Chemical

    Ø Biological

    Ø Psychological

    Ø Electrical

    Ø Mechanical

    Ø Machinery

    Ø Ergonomics

    Ø Radiation

    Ø Material depreciation, failures and changes

    Ø Human error

    Ø Environmental factor



    B) RISK MATRIX TABLE



    CONSEQUENCES
    LIKELIHOOD

    Very Likely (4)
    Likely (3)
    Unlikely (2)
    Highly Unlikely (1)

    Fatality (4)
    High (16)
    High (12)
    High (8)
    Medium (4)

    Major Injuries (3)
    High (12)
    High (9)
    Medium (6)
    Medium (3)

    Minor Injuries (2)
    High (8)
    Medium (6)
    Medium (4)
    Low (2)

    Negligible Injuries (1)
    Medium (4)
    Medium (3)
    Low (2)
    Low (1)




    RISK = CONSEQUENCES x LIKELIHOOD



    Description of likelihood



    Ø Very likely : Could happen frequently

    Ø Likely : Could happen occasionally

    Ø Unlikely : Could happen but only rarely

    Ø Highly unlikely : Could happen but probably never will



    Description of consequences



    Ø Fatality

    Ø Major injuries : Normally irreversible injury or damage to health

    Ø Minor injury : Normally reversible injury or damage to health

    Ø Negligible injury : First aid



    C) HIERARCHY OF CONTROL MEASURES



    Ø Elimination

    Ø Substitution

    Ø Isolation

    Ø Engineering control

    Ø Administrative control

    Ø Personal protective equipment
