Always secure cylinders before removing the cylinder valve protection cap.
Do not drag or roll cylinders. Use a cylinder hand truck to move large cylinders.
Wear safety glasses when working with compressed gases.
Store cylinders in an upright position.
Do not store cylinders in a hazardous location.
Store cylinders away from possible sources of ignition.
Keep regulators and related equipment in the same gas service. Do not change service or adapt
equipment without consulting your gas supplier.
Refer to local shipping regulations for hydrogen supply cylinder shipping instructions.
Regulators for Compressed Gases
When connecting a regulator to a large cylinder:
Ensure the cylinder valve and regulator connection match.
Ensure the 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.
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
The MicroFID II detector uses a hydrogen flame to ionize samples and produce Total Volatile Organic
Compound (TVOC) readings. The quality and purity of the Hydrogen gas is very important to the
accuracy of the detector.
WARNING
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.
The MSDS will be provided by the gas supplier when the gas is ordered.
