Step 1: Hazard Identification:
 
When must you identify hazards?
  • Before setting up and using a workplace
  • When planning work processes
  • Before installing, commissioning or erecting plant
  • Whenever changes are made to the:
    • Workplace
    • System or method of work
    • Plant used
    • Chemicals used
  • Whenever new information regarding work processes becomes available

  

Step 2: Risk Assessment
 
This is a 2 step process, involving:
  • Inherent Risk the level of risk that exists WITHOUT controls in place
  • Residual Risk looks at the quality of the controls in place and calculates the risk employees are actually exposed to

We usually assess:

  • Likelihood
  • Consequence
