OSHA demonstrates several aspects of hospital infection control and<unk>  engineering controls (dedicated air ductwork), PPE (N95 respirators), warning signs and labels (controlled entry), dedicated disposal container, and enhanced housekeeping practices. In health care facilities,<unk> represents one of several measures that can be taken to implement in infection control: the prevention of communicable diseases from being transmitted from a patient to other patients, health care workers, and visitors, or from outsiders to a particular patient (reverse<unk> . Various forms of<unk> exist, in some of which contact procedures are modified, and others in which the patient is kept away from all other people. In a system devised, and periodically revised, by the U.S. Centers for Disease Control and Prevention (CDC), various levels of patient<unk> comprise application of one or more formally described "precaution".<unk> is most commonly used when a patient is known to have a contagious (transmissible from person-to-person) viral or bacterial illness. Special equipment is used in the management of patients in the various forms of<unk>  These most commonly include items of personal protective equipment (gowns, masks, and gloves) and engineering controls (positive pressure rooms, negative pressure rooms, laminar air flow equipment, and various mechanical and structural barriers). Dedicated<unk> wards may be pre-built into hospitals, or<unk> units may be temporarily designated in facilities in the midst of an epidemic emergency.<unk> should not be confused with quarantine or biocontainment. Quarantine is the compulsory separation and confinement, with restriction of movement, of individuals or groups who have potentially been exposed to an infectious microorganism, to prevent further infections, should infection occur. Biocontainment refers to laboratory biosafety in microbiology laboratories in which the physical containment (BSL-3, BSL-4) of highly pathogenic organisms is accomplished through built-in engineering controls. When<unk> is applied to a community or a geographic area it is known as a cordon sanitaire. Reverse<unk> of a community, to protect its inhabitants from coming into contact with an infectious disease, is known as protective sequestration.
