Protective Clothing and Equipment

means of protecting workers from unhealthy environmental conditions —for example, dust, gases, vapors, intense ultraviolet and infrared radiation, bright flashes of light, high levels of radio-activity, noises, vibrations, toxic chemicals, and bacterial preparations. Special protective clothing (uniforms, overalls, underwear, aprons, and gauntlets) made of natural and synthetic fabrics can be easily laundered, decontaminated, and rendered harmless. Protective footwear (boots, shoes, and galoshes), gloves, and sleeves are made of leather, rubber, plastic, and tarpaulin. Casques, helmets, hats, kerchiefs, and little caps are worn to protect the head from injuries and burns. The eyes are protected by goggles, half-masks, and head or hand shields. The respiratory organs are protected by filters—antidust and antigas respirators—and insulating devices, such as hoses, pneumatic helmets, pneumatic suits, and individual oxygen-supply units. Protection from the harmful effects of noise is provided by antinoise devices, such as earplugs and earmuffs covering the helix. Protective clothing and equipment are selected for either permanent or temporary use, depending upon working conditions and the types of operations taking place.
