• Do not heat the cylinders or expose them to direct sunlight.
The cylinders may rupture at high temperatures.
• Do not mutilate cylinders.
• Do not drag or roll cylinders. Large cylinders should only be
moved on carts designed for compressed gas cylinders. Do
not move cylinders without the valve protection cap in
place.
• Always secure cylinders before removing the cylinder valve
protection cap. Always secure the calibration gas cylinder
before connecting the regulator and adapter tubing.
• Use only the specified regulator for the carrier and
calibration gas cylinders.
• Never plug, obstruct or tamper with safety relief devices.
• Wear safety glasses and ear protection when working with
compressed gases.
• When using hydrogen or methane, special care must be
taken to avoid the buildup of explosive gas mixtures in the
GC oven.
• Ensure that all hydrogen line couplings are leak-free and do
not allow hydrogen to be vent inside the oven.
Regulators for Compressed Gases—Use only approved regulators
for gas supply lines and observe the following:
• Use only the specified regulator for carrier and calibration
gas. Confirm regulator type and material with your specialty
gas supplier.
• Mark each regulator with its intended service and never use
a regulator for more than one service. Do not change gas
service, or adapt equipment without consulting your gas
supplier.
• Ensure regulator construction materials are compatible with
the gas, and that the cylinder pressure gauge will withstand
the cylinder pressure.
• Never use the regulator as a shut-off valve. Close the
cylinder valve when it is not in use.
• Do not subject the regulator to an inlet pressure greater than
recommended.
