Detailing your JSA

Take a deeper look into developing a job hazard analysis.

A question; Is it a job hazard analysis or a job safety analysis? Hazards are to be eliminated and safety is to be promoted. Whatever you call it the end result is beneficial to the folks doing the job.

Okay, now you want to begin to develop my JSA, which jobs should you start with?

Here is where you can prioritize the jobs tasks.
• Consider the jobs that create the most exposure or there is a history of injuries.
• What about jobs without a history but have the potential of a serious injury?
• A new piece of equipment or
• A rewritten procedure.

Be a hazard detective and find the answers to these kinds of questions:.
• What can go wrong?
• What are the consequences?
• What are other contributing factors?
• How likely is it that the hazard will occur?

Where do you begin?
You should assemble all of the resources you’ll need to begin your assessment. As was mentioned in an earlier article, the workers that do this work regularly have a great deal of knowledge and insights to the job are an excellent resource.

You can take a look at your incident and accident history that may show you a trend of occurrences in specific areas. If you track the ‘near-misses’ and close calls, those will show a need for improvement in hazard control.

Also consider a review of equipment failures or losses that have been documented. A JSA can organize the steps that need to be performed in a certain order to reduce any equipment failures.

Now with your histories and personnel in place, begin brainstorming all of the steps with the task. Don’t be too concerned with order of operation at this time, you can organize those later. For now concentrate on any of the individual steps, big and small. You may realize an important step was missed as your work your way through the process.

The tasks will have some sort of associated hazard involved to be listed. Then consider the control measure to be used. There may be a possibility of multiple hazards and controls for a task. As you are developing your JSA you may discover an imminent hazard exists. Don’t wait, correct it immediately.

When you start to list the steps in order, ask what the hazard at this step is and how can it be prevented. For instance,
• the task: place 2X10 into lathe,
• the hazard: hand injury from splinters, (one of multiple hazards)
• the control: wear leather gloves

Remember to list important steps and potential “nip-points” that may cause an injury, but don’t overload your JSA. Avoid having your JSA so detailed it becomes a burden to read, but don’t leave it so broad that you miss an important detail. You want to have the workers be reminded of the hazards that can occur at specific steps when they review the JSA.

Also, think of your JSA as a living document that can be revised as necessary.

Nearly every job can be broken down into job tasks or steps. If you are creating a new job task you may discover gaps in the JSA as you put it into place. If you are revising an existing JSA you may want to watch an employee perform the job and list each step as the worker takes it. Record enough information to describe each job action without getting overly detailed. If you observe a job task be sure that the worker knows you are observing the job, not the workers performance of that job.

When you have enough data to create your JSA there are different styles or formats you can use. Some JSA’s will have photographs of the step pointing out a particular hazard, others reference the OSHA standard. It is all up to you. Just remember to list the task, the steps involved, the hazards of doing the step, and what control measures are used to eliminate the hazard.

The useful analysis gives the worker a good understanding of the potential hazards of the job task and how to avoid it..
