Job Safety Analysis (JSA) is a safety management tool in which the risks or hazards of a specific job in the workplace are identified, and then measures to eliminate or control those hazards are determined and implemented.

More specifically, a job safety analysis is a process of systematically evaluating certain jobs, tasks, processes or procedures and eliminating or reducing the risks or hazards to as low as reasonably practical (ALARP) in order to protect workers from injury or illness.

The JSA process is documented and the JSA document is used in the workplace or at the job site to guide workers in safe job performance.

The JSA document is also a living document that is adjusted as conditions warrant.

The JSA process begins with identification of the potential hazards or risks associated with a particular job.

Once the hazards are understood, the consequences of those hazards are then identified, followed by control measures to eliminate or mitigate the hazards.

A more detailed JSA can be performed by breaking the job into steps and identifying specific hazards and control measures for each job step, providing the worker with a documented set of safe job procedures. Some JSA processes also include a risk assessment that lists the probability of each hazard occurring and the severity of the consequences, as well as the effectiveness of the control measures.

The purpose of a conducting and writing a JSA is to better understand the hazards of a particular procedure, so you can take steps to mitigate them.

When performed correctly, JSAs also promote better safety communication and engagement among management and employees.

how to conduct a JSA into 6 simple steps, with added tips on how to make your JSAs more effective.

Step 1: Choose the Procedure

The first step in performing a JSA is to identify which procedures you’ll focus on.

High-priority areas should include procedures associated with:

• A history of past injuries or a high frequency of safety incidents.

• High potential to cause an injury.

• Potentially high severity of incidents.

• Infrequent use and low hazard awareness.

• New processes or equipment, including recently changed processes.

 

Step 2: Break the Job Into Steps

The second step is to take the job procedure under analysis and break it into steps.

The best way to do this is to observe an employee as he or she is doing the job, and some people even find it helpful to take video for review.

Your goal should be to break it down into manageable chunks.

You don’t want it to be so general that you’re omitting key steps, and yet you also don’t want to get so granular that you have too many steps. The general rule of thumb is 10 or fewer steps.

Step 3: Identify Hazards

At this point, you need to look at each step and pinpoint what could go wrong at each point. Ask yourself questions such as:

• Do moving objects or equipment pieces pose a hazard?

• Is any lifting, pushing or pulling required that might cause strain?

• Could the employee slip, trip or fall?

• Are environmental hazards like extreme temperatures, lighting or noise a concern?

• Are harmful substances such as chemicals, dust or fumes involved?

 

Step 4: Implement Solutions

For each hazard, you should identify controls that mitigate the risk of a safety incident. In the following order of preference, look for ways to:

• Eliminate the hazard: This strategy is the most effective. Potential measures include using a different process altogether, modifying the process or tools, substituting materials and adapting the work environment (such as improving ventilation).

• Contain the hazard: If you can’t eliminate the hazard, controls such as machine guards or work booths may help contain the hazard.

• Revise your work procedures: Whenever possible, you should look for ways to modify the procedure to lower its risk. This could mean adding steps or changing them around.

• Reduce job frequency: If you can’t do any of the above, you should look for ways to minimize how often employees perform a certain job.

 

Step 5: Communicate the Findings

All the work you’ve done to this point is useless if you’re just filing your JSA away in a binder somewhere. The entire purpose is to help people understand how to work more safely, so make sure to:

• Distribute copies of the JSA to all affected employees.

• Include safety measures identified in the JSA in employee training programs.

• Make the JSA easily accessible to workers, whether with hard copies or on your EHS Software.

• Use the JSA to inform refresher training for infrequent jobs.

 

Step 6: Review and Update

A JSA should be a dynamic document that management and employees collaborate on to review and update regularly. Areas to focus on here include:

• Periodic follow-up: A manager or supervisor should observe the procedure and compare it to the JSA on a monthly basis.

• After an incident: Part of the incident investigation process should be a comparison of what happened against JSA procedures.

This can help you identify whether you have a gap in the JSA, or whether an employee needs additional training.

•Process or equipment changes: Whenever you introduce new equipment or processes, or if you revise processes, you need to take a look at the relevant JSAs.

 

When all is said and done, a JSA is only as good as the effort you put into it.

If you just check the box, you’re not likely to get results. Follow these steps, however, and you’ll be on a more reliable path to safe work.
