Gowning refers to wearing special garments to enter controlled environments and avoid contamination. It aims to protect workers from chemicals and products from contamination. Gowning can cover the head, beard, face, torso, legs, feet and hands. Proper preparation includes showering, shaving, brushing teeth, selecting non-shedding clothing and removing jewelry. The gowning process involves washing hands, changing into factory gowns, inspecting oneself, and following personnel routes. Degowning involves removing disposable items and reusable garments, washing hands and changing back into street clothes.
