The whole idea is in the top line: Look at the job. Find the hazards. Control the risks.

What is JSA?

JSA is a simple, proactive process you do before, during and after a job to make sure nothing hurts people, equipment, or the environment.

It's also called JHA - Job Hazard Analysis. Same thing. You don't wait for an accident to learn, you break the job down in advance and ask "what could go wrong here?"

Why is it important?

The poster lists 4 reasons:

Prevents accidents and injuries

Controls risks before they become incidents

Improves awareness and communication - everyone knows what they are doing and why

Helps everyone work safely and efficiently

In short: Safe jobs save lives, and safe people = successful jobs.

The 6 Steps to Conduct a JSA

This is the heart of it:

1. Select the Job: Choose which task you want to analyze. Prioritize jobs with high injury history, high severity potential, or new jobs.

2. Break Down the Job: Divide the job into key steps in the correct sequence. Not too broad, not too detailed. Usually 4-6 steps.

3. Identify Hazards: For each step, look for potential hazards related to people, equipment, materials, and environment. A hazard is anything that could cause harm.

4. Assess the Risks: For each hazard, determine the level of risk - High, Medium, or Low. Risk is about how likely it is to happen and how bad it would be.

5. Implement Controls: Put measures in place to eliminate or reduce the risk. The poster reminds you of the hierarchy: engineering controls, administrative controls, PPE.

6. Review and Communicate: Share the JSA with the team, make sure everyone understands it, and review it regularly. It's a living document.

Motto here: Plan the job, work it safely! and Think Ahead - Identify. Assess. Control.

The Example at the Bottom

Task: Changing a light bulb at height (on a ladder)

This shows you how it works in practice:

| Step | Job Step | Potential Hazards | Risk Level | Control Measures 

| 1 | Set up ladder and position at work area | Ladder on uneven ground, Poor positioning, Falls | High | Check ground is level and firm, Use a proper ladder of right height, Barricade the area / keep others away 

| 2 | Climb the ladder to reach the light fixture | Fall from height, Loss of balance, Dropped tools | Medium | Wear full body harness if required, Keep 3 points of contact, Use tool bag / secure tools 

| 3 | Remove old bulb and install new bulb | Electrical shock, Hot surfaces, Broken glass | Medium | Isolate power if required, Use insulated gloves, Handle glass carefully / use eye protection 

| 4 | Test the light and clean up | Electric shock, Slips/trips, Dropped materials | Low | Ensure power is off before testing, Clean and remove waste, Store tools and ladder safely |

Notice how the risk goes from High to Low as you put controls in place. That's the goal of JSA - it turns risks into safe actions.

In your field, you'd want the actual workers doing the job involved in creating the JSA, not just the HSE officer writing it in an office. They know the shortcuts and the real hazards. 🏗️🦺🚥🚧🗼🌡️
