20. If the work station is to be used in a confined space, make sure the space is
well ventilated and the concentration of toxic contaminants cannot
accumulate greater than the TWA.
21. 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.
22. Only chemicals that can be safely adsorbed and treated with specific carbon
based filters are appropriate for use in this enclosure. Two carbon filters
must always be used. Contact Labconco for chemical assessment.
23. 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.
24. 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.
25. For all procedures, adjust face velocity between 60 and 100 FPM for
effective operation.
26. Leave the blower on for at least one minute after work in the enclosure has
been completed.
27. If a chemical is spilled on the work surface, DO NOT switch off the
blower until all traces have been removed.
28. Tag the enclosure with appropriate warning if filters have been removed for
service.
29. If the blower fails during use, processes should cease and the area should
be vacated and ventilated.
30. Always refer to the NIOSH Pocket Guide to Chemical Hazards before
proceeding (See Appendix E). For additional help with filter and chemical
selection contact Labconco at 1-800-821-5525 or 1-816-333-8811.
