Ventilation Fume Hood Testing & Certification in the Midwest

Lab Inspection Services Keep Your Facility ANSI/ASHRAE, IEST, ISO & NSF-Compliant

Fume Hood Velocity TestingOur laboratory testing and certification experts are trained and equipped to ensure your lab facility maintains or exceeds regulatory compliance. Compliant labs create a workplace which is both ecologically responsible and adheres to rigorous safety standards for your employees.

We service research and industrial laboratories throughout the Midwest and Great Lakes regions of the United States.

If your facility is outside of these states, certification and testing services are still available during the installation process. Contact one of our project managers for more information.

PSA offers testing and certification services for laboratory containment devices, including the following:

Chemical Fume Hood Certification

We recommend all new hood installations be tested on-site as mandated by the ANSI/AIHA/ASSE Z9.5-2012 Standard for laboratory ventilation. In addition to new types of fume hoods, we also recommend hoods which have never been performance tested undergo benchmarking to ensure optimal performance.

PSA uses the ANSI/ASHRAE 110-1995 Test Method to evaluate chemical fume hood function. This test is recommended for originally commissioning a new hood, verifying functionality of never-tested hoods, or when major mechanical changes are made to a hood or the lab in which the hood operates. ANSI/ASHRAE 110-1995 is a quantitative test using tracer gas to measure hood containment ability in parts per million (ppm).

After testing, PSA will provide a performance report for each fume hood.

Following the initial ANSI/ASHRAE 110-1995 evaluation, a less rigorous test can be used for required annual evaluations. This comprehensive annual inspection ensures the hood is providing the same level of protection as found during the original inspection.

Biological Safety Cabinet Inspections

To ensure proper function, biosafety cabinets must be certified at equipment installation and annually thereafter. The certification procedure as outlined by NSF International's Standard 49 ensures proper air balance and leak-free filters. PSA holds an NSF Accreditation for Class II Biosafety Cabinet Field Certification (certificate number C0106671-02).

Snorkel Fume Hood CertificationPrimary Testing

Secondary Testing

Laminar Flow Hood Certification

Laminar flow benches, also known as Unidirectional Flow Clean Air Devices, are to be certified at installation and annually thereafter. PSA follows IEST-RP-CC002.3 and ISO14644-7 as the recognized standards.

This certification ensures the laminar flow devices are operating at the correct airflow and the filters are sealed to provide particulate-free air to the work area. PSA's technicians have the latest factory-calibrated equipment and training.

Clean Room Ventilation Standards Testing

High Performance Fume Hoods in Midwest Lab

Like all laboratory safety equipment, clean rooms must be commissioned at startup and validated annually thereafter. In addition to using regularly-calibrated testing equipment, PSA holds membership in the Controlled Environment Testing Association (CETA).

PSA's thorough testing includes:

A Wide Variety of Fume Hood Types and Designs

We have the following types of fume hoods available:

High Performance Perchloric Acid Snorkel Exhaust
Airfoil Bypass Radioisotope Canopy
Add Air Walk-In Variable Air Volume (VAV)
Low Bench Demonstration Thin Wall
