11. The use of safety goggles, protective clothing, gloves and any other

personal protective equipment recommended by your safety officer should
be used.

12. The sash must remain in the down position while using the enclosure.

13. Proper performance of the enclosure depends largely upon its location and

the operator’s work habits. Consult the references in Appendix D.

14. The enclosure should be recertified whenever it is serviced or at least

annually thereafter.

15. The HEPA filter provides personnel and environmental protection from

particulate matter. Because room air is drawn over the work surface during
operation, this enclosure should not be used for operations requiring
product protection from environmental contamination.

16. 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.

17. 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.

18. 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.

19. 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. With normal usage, the HEPA filters
will last two to five years before requiring replacement.

20. Ensure that the filtered enclosure 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.

21. Use of an open flame must be avoided with the enclosure. Open flames

may disrupt the airflow patterns in the enclosure and cause a fire hazard
with volatile solvents.
