Chapter 4: High Performance Features and Safety
28. Only nuisance powders, biohazardous and particulates
removed by HEPA filters and trace chemicals which can be
safely adsorbed and treated with specific carbon based
filters are appropriate for use in this enclosure.
29. 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 filter may be saturated or inadequate.
Contact Labconco for help with chemical assessment.
30. Use the smallest possible quantity of chemical(s) within the
enclosure and never exceed the amount, which can be
effectively adsorbed by the Odor Control carbon filter
before breakthrough.
31. Adjust face velocity to fall between 75 and 105 FPM for
biological procedures.
32. Leave the blower on for at least one minute after work in
the enclosure has been completed.
33. If a chemical, powder or particulates are spilled on the
work surface, DO NOT switch off the blower until all
traces have been removed.
34. Tag enclosures with appropriate warning, if filters have
been removed for service.
35. If the blower fails during use, processes should cease and
the area should be vacated and ventilated.
36. Always refer to the NIOSH Pocket Guide to Chemical
Hazards before proceeding.
