When should a job safety analysis (JSA) be done?
To ensure hazards, unwanted events and potential risks are properly captured and addressed, a job safety analysis (JSA) should be performed at the job site prior to carrying out the job.
During the assignment of a job that has inadequate or no procedures, the work team (with or without the participation of the supervisor) should complete a JSA.
At the completion of the JSA process, the supervisor should review and sign off the JSA where appropriate.
In general, a JSA should only be applied to a job when:
- the potential risks are known to be low
- there is no safe work procedure (SWP) or similar document
- developing, modifying or reviewing an SWP or similar document.
When should a JSA not be done?
If a job is considered to be ‘high risk’ by the supervisor or the team, a formal risk assessment (other than a JSA) should be conducted by an appropriate team.
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 (i.e. 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).
The JSA process can be summarised under the following steps:
- document the activity - assemble those involved in the activity and, using a JSA worksheet, write down the tasks that make up the activity, step by step
- identify the hazards - for each task, identify what part of the task may cause injury to those doing the work or to anyone else nearby
- document the control measures - for each hazard identified, list the measures that need to be implemented to eliminate or minimise any likely risk of injury to those involved
- identify who is responsible - document the name of the person responsible for implementing the control measure
- monitor and review - ensure the activity is supervised to confirm the documented process is being followed, and review the JSA when
- a documented activity changes
- there is a change of personnel
- after an appropriate length of time.
Appropriate training, competency and understanding of the task is required for the supervisor to:
- determine the level of risk associated with a job attracts
- know when to recommend carrying out a more appropriate risk assessment than a JSA.
