3. Application of a JSA

On completion of the JSA, the supervisor is required to review and sign off the JSA where appropriate. If a job is considered to be 'high risk' by the supervisor or the team (during personal prestart checks), a formal risk assessment as appropriate other than a JSA should be conducted by an appropriate team.

The below figure illustrates a suggested JSA flow chart.

Appropriate training, competency and understanding of the task is required for the supervisor to determine the level of risk a job attracts. In general, a JSA should only be applied to a job when:

  • The hazards and potential or resultant risks are known to be low
  • There is no procedure or SWI developing, modifying or reviewing a procedure of SWI (where appropriate).

A JSA should not be conducted as the primary tool to identify hazards and controls where the job:

  • Has the potential for serious injuries, illness, equipment damage or environmental harm
  • Is new and has not been conducted before
  • Is of a long duration (that is over one shift)
  • Involves multiple work teams
  • Is known to have had a history of accidents or near misses
  • Is unusual or complex
  • Involves the use of new equipment, tools, or chemicals
  • Involves interaction with many interdependent systems (such as electrical, mechanical or hydraulic systems).

It should also not be used as the primary tool for jobs where there is a new regulatory requirement in place or where there is a change in the process of performing a job.

  • Suspended loads
  • Contaminated air
  
  • Disease organisms
  • High stress levels
  • Fatigue
  • Extreme or inclement weather
  • Holes or drop-offs
