OSHA hazard assessment requirements: PPE, certification, and what inspectors check
Key takeaways
- A hazard assessment is a prerequisite to PPE selection — you cannot pick PPE correctly without first evaluating the hazards.
- The assessment must be certified in writing, identifying the workplace, the certifier, and the date.
- OSHA does not require a separate form per employee, but it does require evidence the evaluation actually occurred.
- Hazard assessments feed multiple programs — PPE, respiratory protection, and hearing conservation all depend on a defensible exposure evaluation.
What does OSHA require in a hazard assessment?
Under 29 CFR 1910.132(d)(1), the employer must assess the workplace to determine whether hazards are present, or are likely to be present, that necessitate the use of personal protective equipment. If such hazards exist, the employer must select and require appropriate PPE, communicate the selection decisions to affected employees, and select PPE that properly fits each affected employee.
A defensible assessment walks the actual work areas, considers each task, and evaluates impact, penetration, compression, chemical, heat, harmful dust, light radiation, and other hazard categories. It is a process, not a checkbox — the output drives every downstream PPE decision.
What must the written certification include?
1910.132(d)(2) requires the employer to verify that the required workplace hazard assessment has been performed through a written certification. That certification must identify the workplace evaluated, identify the person certifying that the evaluation has been performed, and give the date(s) of the hazard assessment.
OSHA does not prescribe a specific form. A single document covering multiple areas is acceptable as long as it contains all three required elements and accurately reflects the spaces and tasks that were evaluated.
How does the hazard assessment connect to other standards?
The hazard assessment is foundational. Respiratory Protection (1910.134) depends on a determination of airborne hazards; the Occupational Noise standard (1910.95) depends on exposure monitoring; and substance-specific standards such as Hazard Communication (1910.1200) require evaluation of chemical hazards. A weak hazard assessment cascades into weak programs across the board.
For industrial-hygiene exposures, qualitative walkthroughs are often only the starting point — air sampling, noise dosimetry, or other quantitative monitoring may be needed to defensibly characterize the exposure and select controls.
What do inspectors look for first?
Inspectors typically ask to see the written certification and then test whether it matches the floor. If the certification names work areas that have changed, omits a process that obviously requires PPE, or cannot identify who performed the evaluation, the assessment is treated as not having been properly performed.
The most common finding is not the absence of PPE but the absence of a documented assessment justifying the PPE in use — or the use of PPE that the assessment never actually evaluated.

Frequently asked questions
Does OSHA require the hazard assessment to be in writing? +
The assessment itself need not follow a prescribed format, but 29 CFR 1910.132(d)(2) requires a written certification that the assessment was performed. That certification must identify the workplace, the person certifying the evaluation, and the date(s) it was conducted.
Do I need a separate hazard assessment for every employee? +
No. One assessment can cover a workplace or job category. However, PPE must properly fit each affected employee, so fit and individual exposure still have to be accounted for even when the documented assessment is area- or task-based.
How often should a hazard assessment be updated? +
OSHA does not set a fixed interval in 1910.132, but the assessment must reflect current conditions. Reassess whenever processes, equipment, chemicals, or work areas change — and document the reassessment so the certification stays accurate.
