Provisions to assure proper safety cabinet performance and air system operation must be verified. BSCs should be certified at least annually to assure correct performance. To request service or certification contact the EHS at 517-355-0153.
The functional operation and integrity of each BSC should be certified to NSF Standard 49 at the time of installation and annually thereafter by qualified technicians. Certification includes tests for cabinet integrity, HEPA filter leaks, downflow velocity profile, face velocity, negative pressure/ventilation rate, air-flow smoke pattern, and alarms and interlocks. Optional tests for electrical leaks, lighting intensity, ultraviolet light intensity, noise level and vibration may also be conducted. Special training, skills and equipment are required to perform these tests. Annual certification is required for BSCs that are used for work with human pathogens, recombinant DNA or human derived materials (e.g., cell lines, blood, etc.).
