Under OSHA regulations (29 CFR 1910.132), employers must: conduct a workplace hazard assessment, select PPE that properly fits each affected worker, provide PPE at no cost to employees, and train workers on proper use, care, and limitations. Common PPE includes: hard hats, safety glasses/goggles, hearing protection, respirators, gloves, steel-toed boots, high-visibility vests, and fall protection harnesses. PPE is considered the last line of defense in the hierarchy of controls — engineering and administrative controls should be implemented first.
