Definition of Personal Protective Equipment (PPE)

Personal protective equipment (PPE) is equipment worn to minimize a worker's exposure to hazards that cause serious injuries and illnesses. It includes eye and face protection, hard hats, gloves, safety footwear, hearing protection, respirators, high-visibility apparel, arc-rated clothing, chemical suits and personal fall protection.

PPE sits at the bottom of the hierarchy of controls. It protects only the person wearing it, and only when it is the right equipment, fits properly and is worn and maintained correctly. It doesn't remove the hazard, so it is used alongside, or until, more effective controls are in place.

Key Facts About PPE

  • OSHA's general PPE requirements are in 29 CFR 1910 Subpart I, with construction requirements in 1926 Subpart E.
  • Employers must perform a PPE hazard assessment and certify it in writing.
  • Employers must generally provide required PPE at no cost to workers.
  • Workers must be trained on when PPE is needed, how to wear and adjust it, its limitations and how to care for it.
  • PPE must fit each worker; OSHA requires that it be available in sizes that fit, including for women and smaller workers.
  • Common standards include ANSI Z87.1 for eyewear, ANSI Z89.1 for hard hats and ASTM F2413 for safety footwear.

Example of Personal Protective Equipment

A worker handling corrosive cleaning chemicals wears chemical-resistant gloves, splash goggles and a face shield. These are in addition to the room's ventilation system, an engineering control that already reduces fume exposure, and a written procedure that limits how much chemical is decanted at once.

How to Manage a PPE Program

  1. Assess hazards and consider elimination, substitution and engineering controls first.
  2. Select PPE rated for the specific hazards and suited to the work and the worker.
  3. Fit and issue PPE, including fit testing for tight-fitting respirators.
  4. Train workers and check that PPE is worn correctly.
  5. Inspect, clean, store and replace PPE, and review the program when tasks or hazards change.

Personal Protective Equipment (PPE) Frequently Asked Questions

Why is PPE considered the "last line of defense"?

Because it only protects the person wearing it, and only works if selected correctly, worn properly and maintained. Engineering controls reduce the hazard for everyone in the area regardless of individual behavior, which is why the hierarchy of controls prioritizes them first.

Who is responsible for paying for PPE?

Under OSHA's PPE standard, employers are generally required to provide and pay for required PPE at no cost to employees, with limited exceptions such as ordinary safety-toe footwear and prescription safety eyewear that workers may wear off the job.

How often should PPE be replaced?

It depends on the type and usage. Disposable respirators and gloves are single-use or shift-use, while hard hats, harnesses and safety glasses are replaced when damaged, worn or past the manufacturer's recommended service life, whichever comes first.

Does wearing PPE guarantee protection from a hazard?

No. PPE only provides its rated protection when it is the correct type for the hazard, properly fitted, used correctly and in good condition. A poorly fitted respirator or a damaged glove can give a false sense of security.

What is PPE fit testing and when is it required?

Fit testing verifies that a tight-fitting respirator forms an adequate seal on a worker's face. OSHA requires it before first use, whenever a different respirator is used and at least annually for workers who wear tight-fitting respirators.

Can workers be disciplined for not wearing PPE?

Yes. Employers are expected to enforce PPE rules. Effective programs pair enforcement with comfortable, well-fitting equipment and coaching, since PPE that's uncomfortable or interferes with the work is less likely to be worn.
