Labconco Type C1 Biosafety Cabinet Models 30468 - Manual (Page 43)

Product Service 1-800-522-7658 43
Service Line Requirements
All utility service lines should be ¼ inch O.D., brass, copper, or stainless
steel, and equipped with an easily accessible shut-off valve. If the service
line pressure exceeds 40 PSI, it must be equipped with a pressure regulator
to reduce the line pressure.
Note: The use of flammable gases or solvents should be avoided in the
biosafety cabinet. Open flame in the cabinet will disrupt the laminar airflow
in the cabinet and may damage the HEPA filters. Flammable gases or
solvents may reach explosive concentrations in the cabinet or ductwork. If
you feel that the procedure requires the use of an open flame or flammable
materials, contact the institution’s safety office.
The use of air or gases under high pressure should be avoided as they may
seriously disrupt the airflow patterns in the cabinet.
