17. Increase the face velocity by adjusting the speed control of the motorized
impeller on the XPert Nano Enclosure. Change the filter when the face
velocity falls below acceptable limits established by your Safety Officer.
18. Exhaust ULPA filters are disposed as hazardous waste. The user is
responsible for recording the material and disposing properly. Filters
should be disposed using the disposal bag on XPert enclosures.
19. Ensure only trained operators use the enclosure. New users should review
the User’s Manual and become familiar with the operation of the enclosure.
20. 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 (see
references in Appendix D).
21. For weighing procedures, adjust face velocity between 60 and 100 FPM for
effective operation.
22. Leave the blower on for at least one minute after work in the enclosure has
been completed.
23. If a chemical, powder or particulates are spilled on the work surface, DO
NOT switch off the blower until all traces have been removed.
24. Tag enclosures with appropriate warning, if the enclosure has been disabled
for service.
25. If the blower fails during use, processes should cease and the area should
be vacated and ventilated.
