What Is a Job Hazard Analysis (JHA)?
A job hazard analysis (JHA) is a structured, step-by-step technique for identifying the hazards associated with each step of a job and determining the best way to control those hazards before they cause injury or illness. Also called a job safety analysis (JSA) or task hazard analysis, the JHA breaks a task into its individual steps, identifies the potential dangers at each step and then prescribes specific preventive measures. It is one of the most effective proactive safety tools available - and one of the most underused.
OSHA does not mandate a specific JHA format, but the agency strongly recommends the practice in its publication Job Hazard Analysis (OSHA 3071). Regulatory bodies in Canada, Australia and the UK similarly endorse JHAs as a core element of workplace risk management. When done properly, a JHA does more than satisfy a compliance checkbox - it fundamentally changes how workers think about the tasks they perform every day.
Why Job Hazard Analyses Matter
The value of a JHA lies in its preventive nature. Most workplace incidents are not caused by a single catastrophic failure. They result from a chain of small oversights - a skipped step, a missing guard, an assumption that "it will be fine." A thorough job hazard analysis interrupts that chain before it forms.

- Reduced injury and illness rates. Organizations that integrate JHAs into their safety management systems consistently report fewer recordable incidents. By identifying hazards before work begins, you eliminate exposures rather than react to them.
- Improved worker engagement. When frontline employees participate in the JHA process - as they should - they develop a deeper understanding of the risks they face and take greater ownership of safe work practices.
- Stronger regulatory compliance. OSHA inspectors look for documented evidence of hazard identification. A library of current JHAs demonstrates that your organization takes a systematic approach to safety.
- Better training material. A completed JHA doubles as a training document. New employees can study the analysis before performing a task for the first time, accelerating their competence and confidence.
- Lower costs. Fewer incidents mean lower workers' compensation premiums, less downtime and reduced legal exposure. The return on a well-executed JHA program is measured in multiples.
How to Conduct a Job Hazard Analysis: Step-by-Step
The JHA process is straightforward, but it demands attention to detail and genuine worker involvement. Rushing through it - or worse, completing it from behind a desk without observing the actual work - defeats the purpose entirely.
Step 1: Select the Job to Analyze
You cannot analyze every task simultaneously, so prioritize. Start with jobs that have:
- A history of frequent or severe injuries
- The potential for serious harm, even if incidents have not yet occurred
- New or modified processes, equipment, or materials
- Tasks performed infrequently, where workers may not maintain proficiency
- Complex operations requiring multiple workers or energy sources
OSHA recommends reviewing your injury and illness logs, near-miss reports and workers' compensation data to guide your selection. High-risk tasks such as working at heights, confined space entry, energized electrical work and heavy equipment operation should always be near the top of the list.
Step 2: Break the Job into Steps
Observe the task being performed by an experienced worker. Document each step in sequence - not so broadly that you miss hazards and not so granularly that the analysis becomes unwieldy. Most jobs can be effectively captured in 8 to 15 steps.
For example, a job titled "Changing a Flat Tire on a Company Vehicle" might break down as follows:
- Pull vehicle to a safe location and activate hazard lights
- Retrieve spare tire, jack and lug wrench from the trunk
- Place wheel chocks behind the opposite tires
- Loosen lug nuts on the flat tire
- Position the jack and raise the vehicle
- Remove lug nuts and flat tire
- Mount spare tire and hand-tighten lug nuts
- Lower the vehicle and torque lug nuts to specification
- Store equipment and flat tire; remove wheel chocks
Step 3: Identify the Hazards at Each Step
For every step, ask: "What could go wrong?" Consider all categories of hazards:
- Struck-by or struck-against: Passing traffic, falling tools, shifting loads
- Caught-in or caught-between: Pinch points from jacks, machinery, or equipment
- Falls: Slippery surfaces, uneven ground, elevated work
- Overexertion: Heavy lifting, awkward postures, repetitive motion
- Exposure: Chemical, electrical, thermal, noise, or biological hazards
- Environmental: Weather, lighting, confined spaces, traffic
Do not limit yourself to the obvious. A worker loosening lug nuts on a roadside faces the hazard of passing traffic just as much as the hazard of a slipping wrench. Both must be documented.
Step 4: Determine Preventive Measures
For each hazard, determine how to eliminate or control it. Follow the hierarchy of controls:
- Elimination: Remove the hazard entirely (e.g., use roadside assistance instead of manual tire changes)
- Substitution: Replace the hazardous element with something safer
- Engineering controls: Install guards, barriers, ventilation, or mechanical aids
- Administrative controls: Implement procedures, training, signage, or job rotation
- PPE: Provide personal protective equipment as a last line of defense
The best JHAs combine multiple levels of control. Relying solely on PPE - the weakest control - is a common and dangerous shortcut.
Job Hazard Analysis Template
Use the following structure for your JHA documentation. This format aligns with OSHA guidance and is widely accepted across industries.
| Job Step | Potential Hazard(s) | Preventive Measure(s) |
|---|---|---|
| 1. Pull vehicle to safe location | Struck by passing traffic; vehicle rollback on slope | Use flat, level surface away from traffic lanes; activate hazard lights and deploy reflective triangles; engage parking brake |
| 2. Retrieve equipment from trunk | Overexertion from lifting spare tire; back strain from awkward posture | Use proper lifting technique (bend at knees, keep load close); request assistance if tire exceeds comfortable lift weight |
| 3. Place wheel chocks | Vehicle rollback; chocks displaced on loose gravel | Place chocks firmly against both sides of the tire diagonal from the flat; verify chocks are seated on solid ground |
| 4. Loosen lug nuts | Wrench slippage causing hand/knuckle injury; vehicle shift | Use correct size wrench; push rather than pull; wear work gloves; verify parking brake is set |
| 5. Position jack and raise vehicle | Jack failure; vehicle collapse; pinch points | Use jack on designated lift point only; never place any body part under the vehicle while on jack alone; check jack condition before use |
Your completed JHA should also include: the job title, the date of analysis, the names of the analyst and participating workers, required PPE, required training and a review/approval signature. Store JHAs in a centralized document management system where they can be easily accessed, updated and tracked.
JHA Examples by Industry
Construction: Scaffold Erection
Job steps typically include: inspecting scaffold components, assembling base plates on firm footing, erecting standards and ledgers, installing platform boards, securing guardrails and conducting a final inspection. Key hazards involve falls from height, falling objects striking workers below, caught-between hazards during assembly and structural collapse from improper bracing. Controls include fall protection (harness tied off above), exclusion zones below, competent person supervision and adherence to manufacturer specifications.
Manufacturing: Lockout/Tagout on a Conveyor Belt
This JHA covers the steps for isolating energy, verifying zero-energy state, performing maintenance and restoring the machine to service. Hazards include unexpected startup, stored energy release (hydraulic, pneumatic, capacitive), electrical shock and pinch points during reassembly. Controls follow the OSHA 1910.147 standard: individual locks and tags, try-start verification and a formal removal sequence.
Warehousing: Operating a Forklift in a Loading Dock
Steps include pre-operation inspection, approaching the dock, loading/unloading pallets and securing the dock area. Hazards range from pedestrian strikes and tip-overs to falls from the dock edge and trailer creep. Controls include operator certification, dock locks or wheel chocks on trailers, designated pedestrian pathways and load capacity adherence.
Common Mistakes to Avoid
Even experienced safety professionals make avoidable errors when conducting JHAs. Watch for these pitfalls:
- Completing the JHA without observing the work. Desk-based JHAs miss critical hazards that only become apparent during actual task performance.
- Excluding workers from the process. The people who perform the job know its hazards better than anyone. Their input is not optional - it is essential.
- Writing vague controls. "Be careful" is not a preventive measure. "Use a Class II safety harness anchored to the overhead beam rated for 5,000 lbs" is.
- Failing to review and update. A JHA written three years ago for a process that has since changed is worse than useless - it provides false assurance. Schedule reviews at least annually or whenever a process, equipment, or material changes.
- Filing it away and forgetting it. The JHA should be a living document used during training, pre-job briefings, and workplace inspections. If workers have never seen it, it serves no protective function.
How to Integrate JHAs Into Your Safety Program
A JHA is most powerful when it is connected to the rest of your safety management system, not sitting in isolation. Here is how to integrate it effectively:
- Link JHAs to toolbox talks. Review relevant JHAs during pre-shift safety briefings to reinforce hazard awareness.
- Reference JHAs during inspections. Auditors and supervisors should verify that workers are following the controls specified in the JHA. Digital inspection tools make it easy to cross-reference JHAs in real time.
- Attach JHAs to permits. Hot work permits, confined space permits and excavation permits should reference the applicable JHA.
- Store JHAs in a central, accessible location. Paper binders in the safety office are not accessible to the worker on the shop floor. A cloud-based document management platform ensures every team member can pull up the relevant JHA on their phone or tablet, anywhere, anytime.
- Track completion and review dates. Knowing which JHAs are current and which are overdue is critical. Automated reminders prevent analyses from going stale.
Frequently Asked Questions About Job Hazard Analysis
What is the difference between a JHA and a JSA?
There is no functional difference. Job hazard analysis (JHA) and job safety analysis (JSA) refer to the same process. Some organizations and regulators prefer one term over the other, but the methodology - breaking a job into steps, identifying hazards and prescribing controls - is identical. The terms are used interchangeably across OSHA publications and international safety standards.
How often should a JHA be reviewed?
At a minimum, review each JHA annually. However, you should also review and update a JHA whenever: a process, equipment, or material changes; an incident or near miss occurs during the task; a worker identifies a new hazard; or regulatory requirements change. Treat the JHA as a living document, not a one-time exercise.
Who should be involved in conducting a JHA?
The analysis should involve the workers who actually perform the job, a supervisor familiar with the task and a safety professional or competent person who can ensure the analysis is thorough. Worker involvement is critical - they have firsthand knowledge of the hazards, shortcuts and difficulties that may not be visible to an observer.
Does OSHA require a JHA?
OSHA does not have a specific standard mandating JHAs by name. However, the General Duty Clause (Section 5(a)(1) of the OSH Act) requires employers to provide a workplace free from recognized hazards. Additionally, many specific OSHA standards - such as those for permit-required confined spaces (1910.146), process safety management (1910.119), and construction (29 CFR 1926) - require hazard assessments that are effectively JHAs. Conducting JHAs is considered an industry best practice and demonstrates due diligence.
Can JHAs be completed digitally?
Yes and they should be. Digital JHAs offer significant advantages over paper: they are easier to update, distribute and track. Workers can access them on mobile devices at the point of work. Supervisors can monitor completion rates in real time. And audit trails are automatic. Safety management platforms like Make Safety Easy allow you to create, assign and manage JHAs alongside your inspections, incident reports and training records - all in one place.
Take the Next Step
A job hazard analysis is only as effective as the system that supports it. If your JHAs are buried in filing cabinets or scattered across spreadsheets, they are not protecting anyone. Make Safety Easy gives you a centralized platform to create, manage and track JHAs alongside your inspections, documents and safety records - so every worker has instant access to the information they need to go home safe.
