NSF 49 Biosafety Cabinets Field Certifier Accreditation Program

Allometrics is now an NSF approved testing site!

What is NSF 49 Biosafety Cabinets Certifier Program?


The NSF’s biosafety cabinets accreditation program is the gold standard credential for individuals who certify Class II biosafety cabinets in laboratories, hospitals, and research facilities in North America.

The program requires candidates to complete both written and practical examinations along with continued education. Students desiring to test for certification will also need to complete a 12-month apprenticeship class.

The hands-on exam evaluates a candidate’s ability to perform tests detailed in Annex F of NSF/ANSI 49.

Following initial accreditation, field certifiers must provide pertinent equipment calibration documentation at the beginning of each year.

Reaccreditation is needed every five years. The process can be done either through the accumulation of enough requalification units (continuing education) or through re-examination.
