The air is changed at a minimum of 8 to 10 times per hour. The exhaust is passed through a HEPA filter. All liquid wastes and effluents are inactivated by the thermal disinfection unit consisting of three vessels. Contaminated material is inactivated in the pass-through autoclaves before leaving the laboratory area for disposal. Access is restricted to authorized personnel only by means of an electronic code card security lock system.
Personnel accesses the laboratory area via an airlock system equipped with a shower.
The lock system control can be programmed to enforce mandatory showering. For sterile operations, such as cell culture routine handling, and to ensure operator protection class II biological safety cabinets are used. This cabinet completely isolates the operator from the work area by providing sealed thick rubber gloves.
