25/10/2001· Interim Recommendations for the Selection and Use of Protective Clothing and Respirators Against Biological Agents The approach to any potentially hazardous atmosphere, including biological hazards, must be made with a plan that includes an assessment of hazard and exposure potential, respiratory protection needs, entry conditions, exit routes, and decontamination strategies.

When dealing with biological hazards at this level the use of a positive-pressure personnel suit, with a segregated air supply, is mandatory. The entrance and exit of a Level Four biolab will contain multiple showers, a vacuum room, an ultraviolet-light room, autonomous detection system, and other safety precautions designed to destroy all traces of the biohazard.
