Biological Safety Cabinet Moving and Maintenance Guidelines

Laboratory personnel and Department Business Managers should note that before a biological safety cabinet (BSC) is moved or maintenance is perform, decontamination may be required.

The Centers for Disease Control and Prevention (CDC) and National Institutes of Health (NIH) publication entitled Biosafety in Microbiological and Biomedical Labs found at says:

"BSCs that have been used for work involving infectious materials must be decontaminated before HEPA filters are changed or internal repair work is done"


"Before a BSC is relocated, a risk assessment considering the agents manipulated within the BSC must be performed to determine the need and method for decontamination." 

NSF/ANSI Standard 49 Class II (Laminar Flow) Biosafety Cabinetry states in Appendix G,

"Cabinets potentially contaminated with biological agents should be suitably decontaminated before they are moved to another location."

Therefore, Site Support/Physical Plant/Operations will not/should not work on a BSC until decontamination occurs, nor will they move a BSC unless a risk assessment is performed (by the EHSO) to determine the need for decontamination. Alternatively, the need for decontamination can be presumed.

The University has a contract in place for BSC certification and decontamination. The current vendor on this contract is ENV Services  (1-800-690-3368).

If you have any questions, contact your campus EHSO.
