Biosafety Cabinet Biosafety Level 3 Laboratory Design

Date laboratory location responsible individual queries are based on the biosafety level 3 section of the biosafety in microbiological and biomedical laboratories 5th edition 2007 circle the response that best describes the laboratory in which work will be performed.

Biosafety cabinet biosafety level 3 laboratory design.

Basic laboratory design for biosafety level 3. Biosafety level 3 bsl 3 is the recommended containment for work with agents or toxins that may cause serious or potentially fatal disease through inhalation exposure. Table 1 describes the risk groups table 2 relates them to the laboratory designations and table 3 summarizes the requirements at the four biosafety levels. Hepa filtered exhaust air from a class ii bsc can be safely recirculation back into the laboratory environment if the cabinet is tested and certified at least annually and operated according to manufacturer s recommendations.

For more information on other aspects of the biosafety levels please see the rest of the biosafety section for a general overview. Laboratory containment for human pathogens. Preferably this is a class ii biosafety cabinet or equivalent containment device for work with agents and an autoclave or other suitable method for decontamination within the lab. Class ii a2 biosafety cabinets 3 ft.

The biosafety officer in collaboration with the institutional biosafety committee must approve the location and design of any bsl 3 facility and has final authority to authorize the commencement of bsl 3 work the biosafety level 3 facility design and operational procedures must be documented. The assignment of a biosafety level to a particular work process is made through a protocol driven risk assessment. Width international models biohazard cabinets with advanced ergonomic design excel in user comfort and functionality. The facility must be tested for verification that the design and operational parameters have been.

Bscs can also be connected to the laboratory exhaust system. Biosafety level 1 biosafety level 4 facilities. Laboratories covers all design requirements for biosafety level 1 laboratory work areas. Thimble or canopy connection with partial recirculation to the laboratory space e g for class ii type.

Work at bsl 3 requires enhanced facility design operational controls and special practices which will be outlined in this section. Please see biosafety level 3 guidelines for bsl3 laboratories. A readily available eyewash station is needed. Basic laboratory design for biosafety levels 1 and 2.

Facilities as basic biosafety level 1 basic biosafety level 2 containment biosafety level 3 and maximum containment biosafety level 4. This section focuses primarily on the biosafety considerations for a biosafety level 2 laboratory.
