Chapter 5: Using Your Filtered Enclosure and Appropriate Application

Arrange for minimal disruptions, such as room traffic or entry into the room while the enclosure is in use.

Start-up

Turn on exhaust system and accessory light. Turn off the UV light, if equipped.

Only raise the sash for loading and cleaning.

Check the baffle air slots for obstructions.

Allow the enclosure to operate unobstructed for 1 minute.

Wear a long sleeved lab coat and rubber gloves. Use protective eyewear. Wear a protective mask if appropriate. Consult your Safety Officer for additional personal protective equipment recommendations.

Loading Materials and Equipment

Load only the materials required for the procedure. Do not overload the enclosure.

Do not obstruct the air foil, or rear baffle slots.

Large objects should not be placed close together and should be elevated above the work surface to permit airflow to sweep under the equipment.

After loading, wait one minute to purge airborne contaminants from the work area.

Work Techniques

Keep all materials inside the lower air foil, and perform all contaminated operations as far to the rear of the work area as possible.

Segregate all clean and contaminated materials in the work area.

Avoid using techniques or procedures that disrupt the airflow patterns of the enclosure.

Final Purging

Upon completion of work, the enclosure should be allowed to operate for two to three minutes undisturbed, to purge airborne contaminants from the work area before shutting down the blower.

If equipped, turn on the UV light to decontaminate the work area as determined by your Safety Officer.
