Air currents can disrupt the effective operation of biological safety cabinets.

Locate cabinets:

• away from doors and windows that can be opened
• heavily traveled laboratory areas, and
• potential disruptive equipment such as fans, air conditioners, and ventilation systems  

Biological safety cabinets should be installed in such a manner that fluctuations of the room supply and exhaust air do not cause the cabinet to operate outside its containment parameters.
