Biosafety cabinet classification can be a delicate thing. This is not something that can be done quickly or without great care. When biological safety cabinet testing
is needed, it means that some complex work will be happening that is entirely dependent on the right conditions being present in the atmosphere of the new cabinet. In order to commission such a space, the following requirements must be in place.
Secure HVAC Systems
This is the most important aspect to check out. The HVAC system for the entire building will not be secure enough to work with these biosafety zones. You will need a separate system in order to make things work well. There can be no contamination whatsoever with the air coming to and from other non-secure areas in the building. New testing should be done on this system regularly to ensure there is no crossover happening.
