CDC laboratorian dons an older-model PPPS before entering a Maximum Containment lab, or “suit lab”.<unk> s (PPPS) — or<unk>  pressure protective<unk> s, informally known as "space<unk> s", "moon<unk> s", "blue<unk> s", etc. — are highly specialized, totally encapsulating, industrial protection garments worn only within special biocontainment or maximum containment (BSL-4) laboratory facilities. These facilities research dangerous pathogens which are highly infectious and may have no treatments or vaccines available. These facilities also feature other special equipment and procedures such as airlock entry, quick-drench disinfectant showers, special waste disposal systems, and shower exits. The PPPS is a sophisticated variety of personal protective equipment (PPE), a type of hazmat<unk> , which is air-tight and designed for<unk>  pressure to prevent contamination to the wearer even if the<unk>  becomes damaged. BSL-4 cabinets and "Suit Laboratories" have special engineering and design features to prevent hazardous microorganisms from being disseminated into the outside environment. These biosafety<unk> es, where PPPSs are used, are<unk> es of laboratory rooms which are essentially equivalent to large Class III biosafety cabinets in which the interiors of the PPPSs serve as the "outside" environment for workers. Examples include the biocontainment<unk> es at the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) at Fort Detrick, Maryland and the Maximum Containment Facility (MCF) of the Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia.
