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 off the blower.
Unloading Materials and Equipment

Objects in contact with contaminated material should be surface
decontaminated before removal from the enclosure.

All open trays or containers should be covered before being removed from
the enclosure.

Suitable Applications
NIOSH (National Institute for Occupational Safety and Health, USA) has
established guidelines for chemical cartridge and HEPA filtered respirators.
Suitable applications for the carbon filtered enclosures are based on these
guidelines. As with respirators, chemical contaminants are adsorbed or treated by
carbon.
