What is Job Hazard Analysis (JHA)?

Job Hazard Analysis (JHA), also known as Job Safety Analysis (JSA), is a process used to identify potential hazards associated with a specific job or task and implement controls to eliminate or reduce risks. It involves breaking down a job into individual steps, assessing each step for hazards, and determining engineering controls, administrative measures, or personal protective equipment (PPE) needed to minimize risks.

Why is JHA Important?

Work-related injuries, illnesses, and fatalities occur daily. Many of these incidents can be prevented by systematically identifying and addressing hazards through JHA. A well-implemented JHA helps organizations:

• Reduce workplace accidents and injuries
• Ensure compliance with OSHA and other regulatory standards
• Improve employee safety awareness and engagement
• Enhance operational efficiency and productivity
• Lower workers’ compensation costs
• Promote a proactive safety culture

Key Steps in Conducting a Job Hazard Analysis

A Job Hazard Analysis (JHA) is a structured process designed to identify, evaluate, and mitigate potential hazards associated with a specific job or task. Conducting a JHA involves systematically breaking down a job into its components, identifying hazards at each stage, and implementing effective control measures.

Here are the key steps involved in conducting a Job Hazard Analysis (JHA):

1. Select the Job or Task for Analysis

Not every job requires immediate analysis. Prioritize jobs based on risk factors, such as:

• Jobs with a high injury or near-miss rate.
• Tasks involving hazardous materials, machinery, or extreme conditions.
• New or modified jobs that introduce unknown risks.
• Tasks that require a work permit, such as confined space entry, electrical work, or hot work.
• Infrequently performed jobs that may pose unfamiliar risks.

🔹 Tip: Start with jobs that have the greatest potential for accidents or serious injuries.

2. Break the Job into Individual Steps

A JHA requires breaking down a job into individual steps to analyze each phase for hazards. This process involves:

• Observing a worker perform the job in a real-world setting.
• Listing each step in sequence, ensuring clarity and accuracy.
• Avoiding excessive detail (the steps should be clear but not overly complex).

Example – Welding Task:

1. Set up the welding area.
2. Put on personal protective equipment (PPE).
3. Inspect the welding machine and materials.
4. Begin welding.
5. Turn off the machine and clean up the area.

3. Identify Hazards in Each Job Step

Once the job is broken down, identify potential hazards for each step. Consider:

• Physical hazards: Moving parts, falling objects, sharp tools, confined spaces.
• Chemical hazards: Toxic fumes, spills, explosions, inhalation risks.
• Electrical hazards: Exposed wiring, power surges, electrocution risks.
• Ergonomic hazards: Repetitive motions, awkward postures, lifting strain.
• Environmental hazards: Heat stress, cold exposure, noise levels, radiation.
• Human errors: Improper handling, lack of experience, fatigue.

Example – Welding Task Hazards:

• Step 1: Setting up the welding area → Risk of fire due to flammable materials.
• Step 3: Inspecting welding equipment → Risk of electric shock if wires are damaged.
• Step 4: Welding → Eye damage from UV rays, burns from hot surfaces.

4. Determine and Implement Hazard Control Measures

After identifying hazards, apply effective control measures using the Hierarchy of Controls:

Hierarchy of Controls (Best to Least Effective)

1. Elimination – Remove the hazard entirely (e.g., replacing a toxic chemical with a safer one).
2. Substitution – Use a less hazardous alternative (e.g., using water-based paint instead of solvent-based).
3. Engineering Controls – Modify the environment or equipment to reduce hazards (e.g., machine guards, exhaust ventilation).
4. Administrative Controls – Change work policies or procedures (e.g., job rotation, safety training).
5. Personal Protective Equipment (PPE) – Use protective gear (e.g., gloves, helmets, respirators).

Example – Welding Task Hazard Controls:

5. Train Workers on Hazard Controls

• Explain the JHA findings to employees who perform the task.
• Provide training on new procedures and safety measures.
• Ensure employees understand and properly use PPE.
• Conduct demonstrations or practical exercises to reinforce safe work practices.

Example: If a new welding shield is introduced, ensure workers are trained on its use, limitations, and maintenance.

6. Review and Update the JHA Regularly

JHAs should not be static documents—they need regular updates based on:

• Changes in work processes or equipment.
• New hazards introduced by materials or conditions.
• Incident reports, near-misses, or workplace injuries.
• Feedback from employees performing the tasks.

🔹 Example: If a new robotic welding machine is introduced, update the JHA to address potential new hazards like automated equipment malfunctions or pinch points.

A Job Hazard Analysis (JHA) is a proactive approach to identifying and mitigating risks in the workplace. By following these six key steps, organizations can reduce injuries, improve compliance, and foster a strong safety culture.

2. Focus on High-Risk Jobs First

Some jobs pose greater risks than others. Prioritizing high-risk tasks ensures critical hazards are addressed before they lead to injuries.

Best Practices:

• Start with jobs that have a history of injuries or near-misses.
• Analyze tasks involving hazardous chemicals, heavy machinery, or high-risk environments.
• Include new or modified jobs where risks are not yet fully understood.
• Review OSHA regulations to identify jobs that require hazard assessments.

Example: Confined space work should be prioritized due to risks like low oxygen, toxic gases, or entrapment.

3. Use a Structured JHA Form

A consistent format ensures that hazards, risks, and control measures are clearly documented, easy to understand, and actionable.

Best Practices:

Use a JHA template with structured sections:

• Job steps (break the task into individual actions)
• Hazards associated with each step
• Control measures to eliminate or mitigate hazards
• Make the form easy to read and accessible to all employees.
• Digitize the form for faster updates and sharing.

Example JHA Template:

4. Conduct On-Site Observations

Observing a job in action reveals hidden hazards that may not be apparent in written procedures or theoretical discussions.

Best Practices:

• Watch workers perform tasks to see actual hazards.
• Take photos or videos (where permitted) to analyze movements and potential risks.
• Look for improper work habits, missing PPE, or unsafe conditions.
• Compare documented procedures with real-world execution.

Example: While observing a factory worker, you may notice unguarded machine parts that weren’t listed as hazards in previous assessments.
