Personal Protective Equipment (PPE)

PPE is your last line of defense when a hazard can't be removed — and it's required.

Head to toe

• Head — hard hat (protects from falling/flying objects and bumps).
• Eyes & face — safety glasses, goggles, or a face shield for grinding/cutting.
• Hearing — earplugs or muffs around loud tools and equipment.
• Hands — gloves matched to the task (cut, chemical, impact).
• Feet — sturdy, often steel/composite-toe boots.
• High-visibility clothing near traffic and equipment.
• Respiratory — respirators for dust (silica), fumes, and confined spaces.

Rules of thumb

Wear it correctly, inspect it, and replace damaged gear. PPE only protects you if you actually use it.

Going Deeper (Intermediate)

PPE is the last line of defense — and only works if it's the right type, fitted, and worn. The standards behind each:

• Head: hard hats to ANSI Z89.1 — Type I (top impact) vs Type II (top + lateral); Class E (electrical, 20kV), G (general, 2.2kV), C (conductive, no electrical protection).
• Eyes: ANSI Z87.1 safety glasses; goggles/face shield for splash/grinding.
• Hearing: required above an 8-hr TWA of 85 dBA; plugs/muffs rated by NRR.
• Feet: ASTM safety-toe; Hi-vis: ANSI/ISEA 107 Class 2/3 by road speed.

Advanced / Pro-Level

The PPE that needs a program, not just a purchase:

• Respirators (1926.103 / 1910.134) require medical evaluation → fit test → training before use, annually. Voluntary use still needs Appendix D. Match the cartridge to the hazard (an N95 does nothing for vapors).
• Fall-arrest harness (Subpart M): inspect before every use; retire after any fall; mind the D-ring, shock pack, and rated anchor.
• Cut/chemical gloves selected by hazard (ANSI cut levels A1–A9; permeation charts for chemicals).
• Maintenance: PPE that's cracked, expired, or wrong-sized is "PPE theater." Inspect, fit, replace.

Practice Challenge

A worker will use a half-mask respirator for silica dust. List the three things OSHA requires before they put it on. (Answer: a medical evaluation, a fit test for that make/model/size, and training — plus the correct particulate filter (N/P100); voluntary use still triggers Appendix D.)

In Practice

A grinder throws a metal shard straight at a worker's face — and his safety glasses stop it cold. PPE is boring right up until the second it saves your eyesight.

Common Mistakes to Avoid

• Skipping PPE for 'quick' tasks
• Wearing damaged or wrong-rated PPE
• Not matching gloves and protection to the hazard

Takeaway: PPE is your last line of defense — wear it correctly head to toe, inspect it, and replace anything damaged.
