Job hazard analysis: from hazard identification to risk reduction

According to the Occupational Safety and Health Administration (OSHA), a job hazard analysis (JHA), sometimes referred to as a job safety analysis, is a systematic method of studying and documenting each step of a job.

Across the United States, employers use JHAs to identify existing and potential hazards, including environmental, health, and safety (EHS) risks, and determine the safest way to perform work. This process aligns with the OSHA General Duty Clause, Section 5(a)(1), and supports compliance with federal and state workplace safety regulations.

A JHA is especially valuable for identifying hard-to-detect hazards that may only surface through a detailed review of each task. While OSHA does not mandate JHAs, they are strongly encouraged by federal and state occupational safety and health agencies as a best practice for preventing workplace injuries and illnesses.

Why it matters for U.S. employers

For organizations operating in the United States, a JHA strengthens your overall EHS program and creates a structured approach to hazard identification and control.

It also supports:

OSHA compliance and inspection readiness
Employee involvement in workplace safety
Risk reduction across operations

 Benefits of performing a job hazard analysis

A job hazard analysis delivers measurable business and safety outcomes. It helps organizations:

Prioritize corrective actions to reduce or eliminate hazards
Avoid OSHA and EPA violations, citations, and penalties
Reduce injury and illness rates among employees
Improve morale and strengthen a positive safety culture
Decrease absenteeism and workers’ compensation claims
Increase productivity by standardizing work processes
Support regulatory compliance under OSHA standards
Lower insurance costs by preventing incidents and property damage

Which jobs should you analyze first?

Ideally, all jobs should be analyzed. Every role, including office-based work, carries some level of risk.

OSHA guidance suggests prioritizing the following:

Jobs with high injury or illness rates
Jobs with a history of near misses
New jobs or newly assigned tasks
Jobs with recent process or procedural changes
All remaining jobs, as resources allow

How to perform a job hazard analysis

A structured, team-based approach delivers the best results.

Step 1: Assemble a JHA team

Include employees who perform the job, supervisors, safety professionals, and maintenance personnel. Provide training on hazard recognition, evaluation, and control, including the hierarchy of controls and PPE requirements.

Step 2: Break down the job

Document each step of the job in sequence using a standardized template tailored to your workplace.

Step 3: Identify hazards

Evaluate each step for potential risks. Ask:

Could a worker be caught in moving machinery?
Is there a risk of flying objects or eye injuries?
Could employees be exposed to falls, struck-by hazards, chemicals, noise, or heat?

Step 4: Evaluate hazards

Assess risk severity and likelihood:

How serious is the potential outcome?
Are existing controls adequate?
What additional controls are needed?

A best practice in U.S. safety programs is to apply a risk assessment method, such as a risk matrix that considers both severity and probability. This allows organizations to prioritize hazards based on risk level rather than treating all hazards equally.

This approach is consistent with ANSI/ASSP Z10 principles and widely used in modern EHS management systems across industry.

Step 5: Reduce or eliminate hazards

Apply practical control measures:

Modify how the job is performed
Improve workstation design and ergonomics
Substitute safer materials
Introduce mechanical solutions
Upgrade tools and equipment
Provide appropriate PPE
Strengthen training programs

Step 6: Obtain approvals and implement

Review the JHA with employees performing the work. Document training, incorporate feedback, and assign responsibility for program management. Maintain records to support OSHA compliance and audits.

Step 7: Review and update regularly

OSHA recommends updating JHAs when:

An injury, illness, or near miss occurs
New equipment, materials, or processes are introduced
Procedures change
Employees raise safety concerns

Periodic reviews, such as annually or biannually, help ensure continued effectiveness.

The takeaway for EHS leaders

Developing job hazard analyses for all jobs is a foundational element of an effective workplace safety and health program in the United States.

A JHA is not just a documentation exercise. It is a proactive, systematic method for identifying hazards, engaging employees, and preventing injuries before they occur.

Organizations that integrate JHAs into daily operations, training, and continuous improvement efforts are better positioned to meet OSHA expectations, reduce risk, and build a sustainable safety culture.

If JHAs are not yet a core part of your program, they should be. Few tools offer the same level of practical impact in protecting workers and strengthening compliance.
