Weekly

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)

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

of the hood, particularly the front of the hood, to
remove any accumulated dust.
• Check all service valves, if so equipped, for
proper operation.
• The hood baffles should be checked for
blockages behind them to ensure that the hood is
maintaining proper airflow.
• All weekly activities.

• Have the fume hood recertified by a qualified
certification technician. See Certifying the
Fiberglass 30 Fume Hood in Chapter 3.
• All monthly activities.
Biannually
• The sash assembly should be checked to ensure
proper operation and to make sure there are no
signs of abnormal wear on the sash pulleys,
cables and clamps.
