Chemical Fume Hood Testing

Fume hoods in mission critical environments must comply with guidelines set forth in OSHA, ANSI, NFPA and ASHRAE in terms of performance and wide lab design. 

A well-balanced face velocity flow is crucial to ensure efficient chemical removal whilst at the same time not over ventilating the air space. Lab fume hood testing entails testing the hood performance for airflow control, face velocity control and draft performance to ensure effective containment and operator safety.

Periodic Inspection

Testing should be performed annually, immediately following suspected damage or after notable changes have been made to the operation characteristics of the fume hood.

Frequent testing can be a good indicator of the status of the hoods and will ensure they are operating as expected under all anticipated conditions.
