An Air mist shower is a contamination control equipment for respiratory protection from inhalation hazards to the operator during the de-gowning process. When a person removes his/her protective clothing he/she also removes primary personal protection (respirator ). The mist air shower is used to reduce the possible deposition of the particulate in the operators breathing zone. Air mist shower also reduces contamination in the de- gowning areas. Air mist shower works by wetting the surface of operators gowning with fine mist causing the powder to stick to the gowning surface instead of becoming airborne contamination.
