We offer testing, certification, and maintenance of fume hoods. Our testing is performed to comply with the standards set by OSHA, ANSI, ASHRAE, and other regulatory bodies. Our reports are left on-site the same day.
Under OSHA Standards, fume hoods should be tested on an annual basis at a minimum to ensure products are working properly. New fume hoods should be tested prior to be used for the first time. Whenever changes are made to the equipment, a re-evaluation should be performed.
