Biosafety Cabinet Biosafety Level 3 Laboratory Design

Basic laboratory design for biosafety level 3.

Biosafety cabinet biosafety level 3 laboratory design.

Laboratories covers all design requirements for biosafety level 1 laboratory work areas. Bscs can also be connected to the laboratory exhaust system. The facility must be tested for verification that the design and operational parameters have been. Bscs are designed to be connected to the laboratory exhaust system in one of two ways.

Basic laboratory design for biosafety levels 1 and 2. Work at bsl 3 requires enhanced facility design operational controls and special practices which will be outlined in this section. A readily available eyewash station is needed. Biosafety level 1 biosafety level 4 facilities.

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. This section focuses primarily on the biosafety considerations for a biosafety level 2 laboratory. Selfclosing lockable doors and biohazard warning signs are also required at all access points. Class ii a2 biosafety cabinets 3 ft.

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. 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. Supply air must be provided in such a manner that prevents positive pressurization of the cabinet. 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.

Please see biosafety level 3 guidelines for bsl3 laboratories. 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. Thimble or canopy connection with partial recirculation to the laboratory space e g for class ii type. Width international models biohazard cabinets with advanced ergonomic design excel in user comfort and functionality.

Laboratory containment for human pathogens. The assignment of a biosafety level to a particular work process is made through a protocol driven risk assessment.
