Introduction
Regulators for Compressed Gases
When connecting a regulator to a large cylinder:
•
Ensure cylinder valve and regulator connection match.
•
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 shut­off valve. Close the cylinder
when it is not in use.
•
Do not subject the regulator to an inlet pressure greater than
recommended.
•
Do not move or detach the regulator when it is pressurized or
when it is in use.
•
Before connection, ensure the gas cylinder valve and the
regulator CGA connection are clean.
•
Turn the pressure control valve on the cylinder all the way out
(close the cylinder). Turn the regulator outlet to off. Open the
gas cylinder valve slowly and check for leaks. Adjust the
delivery pressure and then open the regulator outlet valve.
Hydrogen Gas
Hydrogen gas is a fire and explosion hazard when exposed to heat
or flame. The lower explosive limit (LEL) is 4%. The lower
explosive limit is the minimum concentration of gas or vapor in air
that will ignite in the presence of a source of heat or sparks.
Refer to the Material Safety Data Sheet (MSDS) before handling
this gas. You will receive the MSDS from your gas supplier when
you order the gas.
