14. Avoid the use of flammable gases or solvents in the enclosure if possible.
Care must be taken to ensure against the concentration of flammable or
explosive gases or vapors. Use of an open flame should be avoided in the
enclosure. Open flames may disrupt the airflow patterns in the cabinet,
burn the HEPA filter and damage the filter’s adhesive. Gases under high
pressure should not be used in the enclosure as they may disrupt the airflow
patterns of the cabinet.
15. HEPA filters are only effective for entrapment of particulate matter.
Manipulations that generate gases or vapors from toxic chemicals or
radionuclides, must be evaluated carefully from the standpoint of buildup
to dangerous levels, the decontamination of the enclosure and compliance
with applicable regulations.
16. The surface of the HEPA filter is fragile and should not be touched. Care
must be taken to avoid puncturing the HEPA filter during installation or
normal operation. If you suspect that a HEPA filter has been damaged DO
NOT use the enclosure; contact a local certification agency or Labconco.
17. The HEPA filter in the enclosure 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 amount of time the enclosure is operating and the nature
of work being done in the enclosure.
18. Ensure that the TXE is connected to an electrical service in accordance
with local and national electrical codes. Failure to do so may create a fire
or electrical hazard. Do not remove or service any electrical components
without first disconnecting the filtered enclosure from electrical service.
19. Increase the face velocity by adjusting the speed control of the motorized
impeller on the TXE or change the HEPA filter when the face velocity falls
below acceptable limits established by your Safety Officer.
20. HEPA filters are disposed as hazardous waste. The user is responsible for
recording the chemicals adsorbed or treated by the filters and disposing
properly. HEPA filters should be disposed using the disposal bag on the
TXE.
21. Ensure only trained operators use the enclosure. New users should review
the User’s Manual and become familiar with the operation of the enclosure.
22. Proper operation of the enclosure depends largely upon the enclosure
location and the operator’s work habits. The enclosure should be located
away from traffic patterns, doors, fans, ventilation registers, fume hoods,
and any other air-handling device that could disrupt its airflow patterns.
Consult Chapter 2: Prerequisites and Chapter 3: Getting Started sections of
this manual for further details.
23. Leave the blower on for at least one minute after work in the enclosure has
been completed.
