Approved by the President, March 11, 2002
To define the University of Maryland, Baltimore policy on certification of biosafety cabinets (BSC) and clean air benches (CAB).
- All ventilated cabinets must be performance tested or certified in accordance with manufacturer specifications at least annually. The certifications will follow the NSF-49 Standard (for biosafety cabinets) or the Federal Standard 209E (for clean air benches).
- Frequency of testing is not limited to once a year. Ventilated cabinets used for specialized activities must be certified every six months.
- Performance tests/certifications must be conducted only by contractors authorized by the University of Maryland, Baltimore.
- Ventilated cabinet installations associated with new construction or renovation project specifications should include the statement that, after installation, each ventilated cabinet must be performance tested to the appropriate performance standard (NSF or 209-E) and be certified to the manufacturer's design performance specifications.
- Performance testing or certification must be performed:
- Before initial use;
- After moving a BSC or CAB from one location to another;
- After replacement of high efficiency particulate air (HEPA) filter(s);
- At least annually;
- After possible BSC or CAB damage;
