4. Always work with your hands as far back into the enclosure as possible.
5. Do not work in this enclosure without the exhaust system running.
6. General acid use, as well as perchloric acid use in this enclosure is prohibited.
7. High-level radioisotope materials are prohibited in this enclosure. Consult
your Safety Officer.
8. Avoid cross drafts and limit traffic in front of the enclosure. Air
disturbances created may draw chemical vapors out of the enclosure.
9. The use of safety goggles, protective clothing, gloves and any other personal
protective equipment recommended by your safety officer should be used.
10. Care must be taken to ensure that the concentration of gases or vapors do
not reach flammable or explosive limits. Use of an open flame must be
avoided in the enclosure.
11. Applications that generate gases or vapors from toxic chemicals must be
evaluated carefully so that buildup to levels above the TWA of the
chemical does not occur. Do not work with chemicals having a TWA
below 100 ppm.
12. Ensure that the enclosure is connected to 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 enclosure from electrical service.
13. Dispose of carbon filters as hazardous waste. The user is responsible for
recording the chemicals adsorbed or treated by the filters and disposing properly.
14. Ensure only trained operators use the enclosure. New users should review
the User’s Manual and become familiar with the operation of the enclosure.
15. If the enclosure is to be used in a confined space, make sure the space is
well ventilated and the concentration of chemical vapors cannot accumulate
greater than the TWA.
16. Only chemicals that can be safely adsorbed and treated with specific
carbon-based filters are appropriate for use in this enclosure. Contact
Labconco for chemical assessment.
17. The warning properties (i.e., odor, taste) of the volatile organic compounds
or other material being used in the enclosure must be adequate to provide
an early indication that the carbon filters may be saturated or inadequate.
Contact Labconco for help with chemical assessment.
18. Use the smallest possible quantity of chemical(s) within the enclosure and
never exceed the amount that can be effectively adsorbed by the carbon
filters before breakthrough. Consult Chapter 6 for filter life estimates.
19. Leave the blower on for at least one minute after work in the enclosure has
been completed.
20. If a chemical is spilled on the work surface, DO NOT switch off the
blower until all traces have been removed.
