Chapter 4: High Performance Features and Safety
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.
