Chapter 4: High Performance Features & Safety Precautions
15. 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. Gases under high pressure
should not be used in the enclosure as they may disrupt the airflow
patterns.
16. Manipulations that generate gases or vapors from toxic chemicals
or radionuclides must be evaluated carefully from the standpoint of
buildup to dangerous levels above the TWA of the chemical.
17. Ensure that the work station 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 work
station from electrical service.
18. Carbon filters are disposed as hazardous waste. The user is
responsible for recording the chemicals adsorbed or treated by the
filters and disposing properly.
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. 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.
