Routine Maintenance Schedule

Weekly

Wipe down the interior surfaces of the enclosure with a disinfectant or

cleaner, depending upon the usage of the unit and allow to dry.

Using a damp cloth, clean the exterior surfaces of the enclosure,

particularly the front and top to remove any accumulated dust.

Operate the exhaust system, noting the airflow velocity through the

enclosure using a source of visible smoke. Airflow monitors are
recommended for constant monitoring.

Monthly (or more often as required)

Determine the actual face velocity through the sash opening of the

enclosure where the average reading should be at the specified velocity.
(Use calibrated thermal anemometer or other approved apparatus). Airflow
alarms are recommended for constant monitoring.

The enclosure rear baffle should be checked for any blockage to ensure that

the enclosure is maintaining proper airflow.

All weekly activities.

Check face velocity. Increase speed control or change HEPA filter when

face velocity of the enclosure drops below the recommended speed for your
facility or if the airflow alarm monitor alerts you. Airflow monitors are
recommended.

While the enclosure is filled with the contaminant, test filter condition on

Odor Control carbon filters using the appropriate gas detector tube at
intervals of 20% of the total estimated time. The exception to the 20%
recommendation is formaldehyde or any carcinogen or suspected
carcinogen. These hazardous chemicals must be checked at least every
10% of the total estimated time. Gas detector tubes for the specific
chemicals that are being used in the enclosure can be obtained from your
laboratory supply dealer.

Replace Odor Control carbon filters when chemical breakthrough is

indicated by odor, time, detector tube, or for some chemicals, analytical
instrumentation. See “Replacing Odor Control Carbon Filters” section of
this manual in Chapter 6.

Annually

Replace the fluorescent lamps.

Have the enclosure validated by a qualified certification technician. See

Certification and Recertification in Chapter 6.

All monthly activities.
