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.
Unloading Materials and Equipment

Objects in contact with contaminated material should be surface
decontaminated before removal from the enclosure.

All open trays, weigh vessels or containers should be covered before being
removed from the enclosure.
Shutdown

Turn off the exhaust system and light.
ULPA Filter Applications, Suitability and Guidelines

Weighing and handling of powders.

Release of nonvolatile particulates appropriate for use with a ULPA filter.

The ULPA filtered enclosure provides personal and environmental protection
from particulate matter, hazardous powders and biohazardous materials.
Because room air is drawn through the enclosure during operation, this
enclosure should not be used for operations requiring sample protection from
environmental contamination.

ULPA filters are only effective for entrapment of particulate matter, hazardous
powders and biohazardous materials. Manipulations that generate gases or
vapors, i.e., toxic chemicals or radionuclides, require ventilation to the outside of
the building. The surface of the filter is fragile and should not be touched. Care
must be taken to avoid puncturing the ULPA filter during installation. If you
suspect that a ULPA filter has been damaged, DO NOT use the enclosure. See
Chapter 6 for replacing the ULPA Filter or using a Bag-In/Bag-Out Disposal Bag.

The ULPA filter will gradually accumulate airborne particulate matter from
the room and from work performed in the enclosure. The rate of accumulation
will depend upon the cleanliness of the room air, the operating time, and the
nature of work being performed.

Each Nano Enclosure is provided with a ULPA filter. For powders and
particulates follow the ULPA Filter Bag-In/Bag-Out procedure in Chapter 6
for disposal instructions. For biohazardous materials, follow the
Decontamination Procedure in Chapter 6 for disposal instructions.
