What Is PPE? Personal Protective Equipment Explained
Header image: NIOSH
Quick Answer
Personal protective equipment (PPE) is gear a worker wears to reduce exposure to hazards that can cause serious injury or illness, such as hard hats, safety glasses, earplugs, gloves, respirators, safety boots, and hi-vis vests. OSHA treats PPE as the last line of defense, used when engineering and administrative controls cannot remove the hazard. Employers must assess hazards, select PPE that fits, train workers to use it, and in most cases pay for it.
What Does PPE Stand For?
PPE stands for personal protective equipment. OSHA describes it as equipment worn to minimize exposure to hazards that cause serious workplace injuries and illnesses, whether those hazards are chemical, radiological, physical, electrical, mechanical, or something else. The key word is personal: PPE protects the person wearing it, not the area around them. A guardrail protects everyone near an edge. A harness protects only the worker clipped into it.
The Main Types Of PPE
Most PPE falls into eight categories, each with its own performance standard. When you buy PPE, the standard marking on the product or label is how you confirm it was built and tested for the job.
| Body area | Common PPE | Standard to look for |
|---|---|---|
| Head | Hard hats and safety helmets | ANSI/ISEA Z89.1 (Type I or II, Class G, E, or C) |
| Eye and face | Safety glasses, goggles, face shields | ANSI/ISEA Z87.1 |
| Hearing | Earplugs and earmuffs | Noise Reduction Rating (NRR) on the label |
| Respiratory | Dust masks (filtering facepieces), half-face and full-face respirators | NIOSH approval |
| Hand | Cut, chemical, impact, and insulated gloves | ANSI/ISEA 105 (cut levels A1 to A9) |
| Foot | Safety-toe boots, metatarsal guards | ASTM F2413 |
| Body and visibility | Hi-vis vests and jackets, coveralls, FR clothing | ANSI/ISEA 107 for hi-vis |
| Fall protection | Full-body harnesses, lanyards, self-retracting lifelines | OSHA 1926.502 and ANSI/ASSP Z359 |

Where PPE Fits In The Hierarchy Of Controls
Safety professionals rank hazard controls from most to least effective. This is the hierarchy of controls used by NIOSH and OSHA:
- Elimination: remove the hazard. Build the wall on the ground and tilt it up instead of working at height.
- Substitution: swap in something less hazardous, such as a lower-toxicity coating.
- Engineering controls: isolate people from the hazard with guardrails, machine guards, ventilation, or water on a saw.
- Administrative controls: change how people work through procedures, training, signage, job rotation, and scheduling.
- PPE: protect the individual when the hazard is still there.
PPE sits at the bottom because it depends on every worker wearing the right gear correctly, every time, and because it does nothing to the hazard itself. OSHA says employers must provide PPE when engineering, work practice, and administrative controls are not feasible or do not provide enough protection. In practice, most jobs use several layers together. A crew can have guardrails, a dropped-object plan, and still need hard hats.
What Employers Must Do
OSHA's general PPE rule for general industry is 29 CFR 1910.132, and the construction version is 29 CFR 1926.95. Together they boil down to five duties:
- Assess the hazards. In general industry, employers must survey the workplace for hazards that call for PPE and document it in a written certification listing the workplace, the person who did the assessment, and the date.
- Select PPE that protects and fits. PPE must be of safe design for the work and, in both general industry and construction, selected to properly fit each affected worker. The construction fit language was added effective January 13, 2025.
- Train every user. Workers must know when PPE is needed, what PPE is needed, how to put it on, adjust, wear, and take it off, its limitations, and how to care for, maintain, and dispose of it. Workers must show they understand before they start the work, and they must be retrained when the job or the equipment changes.
- Keep it in good condition. Defective or damaged PPE must not be used.
- Pay for it. With limited exceptions, required PPE must be provided at no cost to workers.
Who Pays For PPE?
The employer, in almost every case. Under 1910.132(h) and 1926.95(d), PPE used to comply with OSHA standards is provided at no cost to employees. The main exceptions:
- Non-specialty safety-toe boots and non-specialty prescription safety glasses, if the employer lets workers wear them off the job.
- Everyday clothing such as long pants, long-sleeve shirts, and normal work boots.
- Ordinary weather gear such as winter coats, rain gear, and ordinary sunglasses.
Replacement PPE is also on the employer, unless a worker lost or intentionally damaged it.
Fit, Comfort, And Compliance
PPE that does not fit does not protect. OSHA notes that poorly fitting PPE can make the difference between being covered and being exposed. A helmet that slides, gloves that bunch, or glasses that fog all get taken off, and a hard hat on the dashboard protects nobody. Comfortable, well-fitted gear that suits the work is one of the most reliable ways to raise compliance. Our article on increasing PPE compliance covers the rest.
Fit includes the full workforce. Stock multiple sizes, including smaller sizes for women and smaller-framed workers. Make sure gear works together: safety glasses under a face shield, earmuffs with a helmet, and gloves that still allow fine motor work.
Caring For And Replacing PPE
- Inspect before each use. Look for cracks, cuts, fading, stretched elastic, and missing parts.
- Follow the manufacturer's service life. Helmets, hi-vis garments, harnesses, and respirator cartridges all have replacement guidance. See when to replace a safety helmet and when to replace a hi-vis vest.
- Retire gear after a hit. A helmet that took an impact or a harness that arrested a fall comes out of service.
- Store it right. Heat, sunlight, and chemicals break down plastics and fabrics. A dashboard is not storage.
PPE Basics Checklist
- Walk the job and list the hazards.
- Try to engineer the hazard out before you rely on PPE.
- Pick PPE marked to the right standard for each hazard.
- Fit-test or size every worker. Stock real size ranges.
- Train, confirm understanding, and document it.
- Inspect, clean, store, and replace on schedule.
PPE Key Facts
Last line of defense: PPE ranks below elimination, substitution, engineering, and administrative controls.
29 CFR 1910.132 and 1926.95: OSHA's general PPE rules for general industry and construction.
No cost to workers: employers pay for required PPE, with narrow exceptions for everyday safety-toe boots, prescription safety glasses, and ordinary clothing.
Fit is required: PPE must be selected to properly fit each worker in general industry and in construction.

Frequently Asked Questions About PPE
Q: What are examples of PPE?
A: Hard hats and safety helmets, safety glasses and goggles, face shields, earplugs and earmuffs, respirators, gloves, safety-toe boots, hi-vis vests, coveralls, and fall protection harnesses.
Q: Why is PPE the last line of defense?
A: It leaves the hazard in place and works only if each worker wears the right gear correctly. Eliminating or engineering out the hazard protects everyone without depending on individual behavior.
Q: Do employers have to pay for PPE?
A: Yes, for PPE required by OSHA, with narrow exceptions such as non-specialty safety-toe boots and prescription safety glasses that workers can wear off the job.
Q: Is a face mask PPE?
A: A NIOSH-approved respirator, such as an N95 filtering facepiece, is respiratory PPE. A cloth or basic surgical mask is not a respirator and does not protect against airborne hazards like silica dust.
