Mark cylinders clearly so there is no doubt as to their contents.
Use only approved regulators and connections.
Use only connector tubing that is chromatographically clean (Varian part
number 0391832600) and has a pressure rating significantly greater than
the highest outlet pressure from the regulator.
GC Safety Practices
Exhaust System
No special exhaust ducting is necessary for GC detectors installed in a well-ventilated
room except when the detectors are used to test hazardous chemicals. If you do install
ducting:
Use only fireproof ducting.
Install a blower at the duct outlet.
Locate duct intakes such that their vibration or air movement does not
affect detector operation.
Check periodically for proper operation of the duct.
Ensure proper ventilation in lab area.
Radioactive Source Detectors
Read carefully and comply with all NOTES, CAUTIONS, and WARNINGS
in the Ni63 ECD manual.
Perform the tests for removable radioactive contamination described in
the Ni63 ECD manual.
Comply with leak test schedules and procedures.
Burn Hazard
Heated or cryogenically cooled zones of gas chromatographs can remain hot or cold for a
considerable time after instrument power is turned off. To prevent painful burns, ensure
that all heated or cooled areas have returned to room temperature or wear adequate hand
protection before you touch potentially hot or cold surfaces.
