NEBB’s Fume Hood Performance Testing program provides certification of firms and individuals that meet the criteria established by NEBB.

As more facilities are using fume hoods in their research laboratories, there is a demand for certified, competent firms to make sure a facility's fume hoods are operating effectively. Certification in Fume Hood Testing (FHT) will offer hospitals, laboratories, and educational facilities proof of technical knowledge, skills and instrumentation to test fume hoods for effectiveness.

Fume Hood Testing Certification Requirements for Firms

In order to become NEBB Certified in Fume Hood Testing, a firm must:
  • Enjoy a reputation for integrity and responsible performance. Six letters of endorsement, five from consulting engineers, architects or building owners and the sixth may be from a contracting firm. All should reflect work that the applicant firm has completed. Firms who are already NEBB Certified in another discipline will not need these letters.
