Now that you have an understanding of how to work in the fume hood, please
review the suggested maintenance schedule and the common service operations
necessary to maintain your fume hood for peak performance.

Only trained and experienced certification technicians should
perform some of the service operations after the fume hood has
been properly decontaminated. DO NOT attempt to perform
these operations if you are not properly trained. The wrench
icon precedes the service operations that require qualified
technicians.

Routine Maintenance Schedule


Weekly

• Using ordinary dish soap to clean the surface inside of the fume hood, and

the work surface.

• Using an appropriate glass cleaner, clean the sash and all glass surfaces.

• Operate the fume hood blower, noting the airflow velocity through the

hood using a source of visible smoke.


Monthly (or more often as required)

• Determine the actual face velocity through the sash opening of the hood

where the average reading should be at the specified velocity. (Use
calibrated thermal anemometer or other approved apparatus).

• Using a damp cloth, clean the exterior surfaces of the hood, particularly

the front of the hood, to remove any accumulated dust.

• Check all service valves, if so equipped, for proper operation.
