Biological Safety Cabinets, Chemical Fume Hoods and Other Primary Barrier Equipment
The Technical Assistance Branch of the Division of Occupational Health and Safety provides various services regarding certification, maintenance, and decontamination of specific primary barrier equipment. Chemical fume hoods and other ventilation systems known as local exhaust ventilation systems or LEVs (down draft tables and sinks, slot hoods, and canopy hoods) are certified when installed and on an annual basis. The certification of these systems includes inspection, adjustment, and verification of air flow velocities and direction.
Another type of primary barrier equipment is the biological safety cabinet. Most types of these cabinets at the NIH provide product, environmental, and personnel protection. Biological safety cabinets are maintained and certified according to the National Sanitation Foundation Standard 49, which is the accepted standard for the biological safety cabinet industry. Various tests are performed to verify air flows, air filter integrity, containment of contaminated cabinet air, and that the cabinet is safe to operate regarding other cabinet operational features. Whenever cabinets are to be moved, internal repairs are to be made, or when filters are to be replaced, these' cabinets must be decontaminated. To arrange for decontamination contact the DOHS Technical Assistance Branch at (301) 496-3353 or (301) 496-3457.
Services are provided for other types of primary barrier equipment, such as, vertical clean benches, cage change stations, animal racks, and animal isolators.
