Job Safety Analysis (JSA): A Simple Step-by-Step Guide With Example

Hey there. I’m Zain, and welcome to today’s video from Zain HSE, where we’re breaking down Job Safety Analysis, or JSA — a simple but powerful tool to help keep workplaces safe.

Whether you are a safety professional, supervisor, or simply looking to improve workplace safety, this step-by-step guide will walk you through the entire process, complete with a practical real-world example.

So, let’s get started.

What Is Job Safety Analysis?

What if you could prevent workplace accidents before they happen?

That’s exactly what a Job Safety Analysis, or JSA, helps you do.

A JSA is a systematic way to identify hazards in a task and control risks before someone gets hurt.

Think of it like a recipe for safety:

Break down the job, spot the dangers, and add safeguards.

When you conduct a JSA, there are several important steps you need to follow.

Let me walk you through them.

Step 1: Select the Job to Analyze

This is where you choose which task needs to be examined for safety risks.

Focus on tasks that are high-risk, have caused incidents or near misses, or are new to your team.

For example, operating machinery, working at heights, or even routine jobs like changing a flat tire.

That’s what we’ll use as our example.

Why?

Because a simple tire change can lead to crushed fingers, back injuries, or worse if it is done unsafely.

Step 2: Break the Job into Steps

Now, take that task and divide it into smaller, manageable actions.

Keep it simple. Aim for around five to ten steps, depending on the job.

Let’s take our flat tire example.

First, park safely on level ground.

Then turn on the hazard lights and set the parking brake.

Gather the required tools, such as the jack, lug wrench, and spare tire.

Loosen the lug nuts before lifting the vehicle.

Then position the jack correctly and lift the vehicle.

And so on.

Breaking the job down helps us see hidden risks.

Step 3: Identify Hazards for Each Step

Here’s where safety gets proactive.

Ask yourself:

What could go wrong with each step?

For example, when parking the vehicle, it could roll if it is not on level ground or the parking brake is not properly applied.

When loosening the lug nuts, the wrench could slip and cause a hand injury.

When lifting the car, the jack could fail or be positioned incorrectly, causing the vehicle to fall and potentially crush someone.

When removing the tire, heavy lifting might cause a back strain or other manual-handling injury.

Every hazard you spot is a chance to prevent an accident.

Step 4: Develop Control Measures

Now, solve those risks.

Controls can include eliminating the hazard where possible, reducing the risk, and using appropriate PPE.

For example, instead of using a jack where a suitable vehicle lift is available, a lift may provide better control for certain maintenance activities.

To reduce the risk of vehicle movement, use wheel chocks and the parking brake.

For personal protection, wear suitable gloves and use proper lifting techniques.

For a tire change, park on level ground, apply the parking brake, and use wheel chocks where appropriate.

When lifting the vehicle, never place any part of your body underneath a vehicle that is supported only by a jack.

For tire handling, use proper lifting techniques and lift with your legs rather than putting unnecessary strain on your back.

Small changes can make a big difference to safety.

Step 5: Document and Implement the JSA

A JSA only works if everyone knows it and follows it.

Document it in a simple table showing the job steps, hazards, and control measures.

Then communicate the JSA to your team and make sure they understand the hazards and required controls before starting the job.

One important point is that a JSA should not just be completed and forgotten.

Review it when the job, equipment, process, or working conditions change, and also after a relevant incident or near miss.

Safety isn’t one and done.

JSA Example: Changing a Flat Tire

Let’s apply this to our example.

We’re changing a flat tire.

We’ve broken the job into steps, identified risks like vehicle rollaway, jack failure, hand injuries, and back injuries, and added controls such as using wheel chocks, the parking brake, the correct jack, and proper lifting techniques.

Simple, right?

But these small steps can prevent serious injuries.

And that’s your complete guide to Job Safety Analysis.

By breaking down tasks, spotting risks, and adding controls, you’re not just complying with rules.

You’re helping prevent accidents and protect people.

Remember, the purpose of a JSA is not just to fill out a form.

The real purpose is to understand the job, identify what could go wrong, and put controls in place before someone gets hurt.

Frequently Asked Questions

What is Job Safety Analysis?

Job Safety Analysis, or JSA, is a systematic process used to break a job into steps, identify hazards associated with those steps, and establish control measures to reduce the risk.

What are the five steps of JSA?

The five basic steps are:

1. Select the job to analyze.
2. Break the job into steps.
3. Identify hazards for each step.
4. Develop control measures.
5. Document and implement the JSA.

Why is JSA important?

JSA helps identify hazards before work starts and allows workers to put appropriate controls in place before an accident happens.

When should a JSA be reviewed?

A JSA should be reviewed when there is a change in the job, equipment, process, or working conditions, and after a relevant incident or near miss.

Who can conduct a JSA?

A JSA should involve people who understand the job and its hazards, such as safety professionals, supervisors, workers, engineers, or other competent personnel.
