Job Hazard Analysis (JHA) is the cornerstone of proactive occupational safety. At its core, a JHA is a structured process that breaks down a job into individual tasks to identify potential hazards and apply controls before work begins. This approach doesn’t just help in meeting regulatory compliance—it saves lives.
JHA is especially important in high-risk environments like construction, manufacturing, warehousing, and oil and gas, but it’s beneficial for all industries.
From a safety culture perspective, JHAs demonstrate a company’s commitment to protecting workers and preventing incidents.

What is Job Hazard Analysis (JHA)?
Job Hazard Analysis (JHA), also known as Job Safety Analysis (JSA), is a proactive method to identify hazards associated with job tasks. It involves observing a job, breaking it down into steps, assessing the risks of each step, and recommending preventive or corrective measures.
Each JHA results in a document that serves as a reference tool for training, audits, and daily pre-task safety meetings.
Why is Job Hazard Analysis (JHA) Important?
Without a structured hazard identification process like JHA, many risks may go unnoticed until an incident occurs. Here’s why JHA is essential:
- Prevents Injuries: Recognizing and eliminating hazards reduces the chance of worker injuries.
- Improves Training: JHAs act as detailed guides for training new or transferred workers.
- Meets Compliance: Regulatory bodies like OSHA (DoFollow) and CCOHS (DoFollow) require hazard assessments in many jurisdictions.
- Builds a Safety Culture: Workers actively participating in JHA build stronger safety awareness.
Steps to Conducting a Job Hazard Analysis (JHA)
The process of developing a JHA follows a logical sequence. Here’s how it works:
1. Select the Job to Be Analyzed
Focus on jobs with:
- A high injury rate
- Complex procedures
- History of near misses
- New or infrequently performed tasks
2. Break Down the Job into Steps
Use observation and worker input to divide the task into 5–10 clear, sequential steps. Each step should describe what is done, not how it is done.
3. Identify Hazards in Each Step
Examine each step for potential risks such as:
- Struck-by or caught-in hazards
- Slips, trips, and falls
- Electrical exposure
- Chemical or biological hazards
4. Determine Preventive Measures
Apply the Hierarchy of Controls:
- Elimination
- Substitution
- Engineering controls
- Administrative controls
- PPE
5. Document and Communicate the JHA
Ensure the completed JHA is:
- Reviewed by supervisors
- Communicated to all workers involved
- Stored for training and reference
Example: Job Hazard Analysis for Ladder Use
| Job Step | Potential Hazard | Recommended Control |
|---|---|---|
| Inspect ladder | Defective equipment | Use a pre-check list, remove unsafe ladder |
| Set up ladder | Tip-over risk | Ensure firm footing, 4:1 ratio, secure top |
| Climb ladder | Fall hazard | Maintain 3-point contact, face the ladder |
| Use tools while on ladder | Dropping tools, overreaching | Use tool belt, reposition ladder frequently |
When Should a JHA Be Reviewed or Updated?
You should revisit your JHA when:
- A near-miss or incident occurs
- New equipment is introduced
- Tasks change or are modified
- After an audit recommendation
Regular review is key to keeping your hazard controls effective and relevant.
Integrating JHA with Other Safety Practices
Job Hazard Analysis (JHA) works best when integrated into a broader safety program. Combine it with:
- Daily Toolbox Talks
- Behavior-Based Safety Observations
- Routine Safety Audits
- Permit to Work Systems
Internal tools like OHSE.ca’s free JHA templates (DoFollow) can streamline the process and ensure your team follows consistent formatting.
Common Mistakes in Job Hazard Analysis
Avoid these errors when conducting JHAs:
- Skipping steps or rushing through the process
- Failing to involve frontline workers
- Not updating the analysis when work conditions change
- Treating JHA as a paperwork exercise instead of a living document
Engagement is key. Workers must feel the JHA is there to protect them, not punish them.
Digital Tools to Improve JHA Efficiency
Today’s safety professionals can use apps and software like:
These tools help with faster documentation, mobile inspections, and cloud storage—making JHA creation and sharing seamless.
Conclusion: Job Hazard Analysis (JHA) is Your Safety Backbone
Job Hazard Analysis (JHA) isn’t just a form—it’s a mindset. By proactively breaking down tasks and planning for risks, workplaces can drastically reduce injuries, boost productivity, and foster a strong culture of safety.
Whether you’re in construction, healthcare, logistics, or labs, a well-done JHA is your best safety insurance.
Start your next shift with a JHA—and finish it without incident.
