BSL 2 / BSL 3 Lab
BSL 2/ BSL 3 indicates laboratories for containment for agents of moderate potential hazards to personnel and the environment where laboratory personnel have specific training in handling pathogenic agents and are supervised by scientists competent in handling infectious agents and associated procedures. The access to the laboratory is restricted when work is being conducted; and all procedures in which infectious aerosols or splashes may be created are conducted in BSCs or other physical containment equipment. Immunization or antibiotic treatment may be available for organisms handled in these labs.
Whereas primary barriers in any laboratory are the personal protective equipment used as part of work practice control, the laboratory infrastructure forms the equally important secondary barrier. Hence the importance of a good lab design cannot be overstated.
