360 Training OSHA 30hr Practice Test

PPE stands for Personal Protective Equipment and refers to the protective gear workers wear to create a barrier between themselves and hazards. It’s a safeguard used when hazards cannot be fully eliminated or reduced enough by other means, and it acts as the last line of defense in the hazard control hierarchy. PPE includes items like gloves, safety glasses or face shields, respirators, hearing protection, hard hats, and protective footwear. The key idea is that PPE protects the worker, but it doesn’t remove the hazard itself or reduce exposure at the source; the hazard remains, just mitigated at the wearer. Other approaches aim to change the work environment or processes—administrative controls change how people work (training, procedures, rotation), substitution replaces the hazard with something less dangerous, and engineering controls modify the workplace to remove or reduce the hazard (guards, ventilation).
