Head protection, typically in the form of hard hats or helmets, shields against falling objects, impact from bumping into stationary objects, or electrical hazards. Face shields and safety goggles provide defense against flying debris, chemical splashes, or other airborne particles that could cause eye injuries. Respirators offer respiratory protection by filtering out harmful gases, vapors, or airborne contaminants, ensuring safe breathing in hazardous environments. Ear protection, such as earplugs or earmuffs, guards against loud noises that could cause hearing damage or loss.
