Planning
Thoroughly understand procedures and equipment required before
beginning work.
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 if so equipped.
Only raise the sash for loading.
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
Only load 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.
