Class III Biological Safety Cabinets, a special type of glovebox, are designed to provide maximum protection for laboratorians from highly infectious biological agents (BSL-3 and BSL-4) and procedures that generate large quantities of bio-aerosols. They are frequently installed in maximum containment laboratories that have access controls and special ventilation. Class III Biological Safety Cabinets are engineered to provide maximum protection for the operator by using a gas-tight enclosure that is completely sealed while giving visibility of the product through a viewing window. There is always a physical barrier between the researcher and the work. Long heavy duty gloves are attached in a gas tight manner to allow the researcher maximum protection and prevent direct contact with the hazardous materials. Access to the interior of the cabinet can be accomplished through a double-door pass-through "interchange" box that can be decontaminated between uses and/or a dunk tank that is accessible through the cabinet floor. Other transfer devices include integrated double-door autoclaves and Rapid Transfer Ports. Class III Biological Safety Cabinet have supply and exhaust air that is HEPA filtered with the exhaust air passing through two HEPA filters (or a HEPA filter and an air incinerator before discharge to the outdoors). The air flow and negative differential pressure is typically maintained by a dedicated independent exhaust system exterior to the cabinet which keeps the cabinet and all associated ducting under negative pressure.
