General Safety 

Never refill CALGAZ cylinders.

• Always use safety glasses when working with high pressure gases and regulators.

• Familiarize yourself with the material safety data sheets (MSDS) before use.

• Do not be lulled into complacency because of the convenient small size of CALGAZ cylinders. The cylinders are high pressure containers and may injure you if not handled with care.

• Protect CALGAZ cylinders from exposure to weather. Moisture can cause surface rust and enter the valve stem resulting in contamination of the gas mixture during engagement of the regulator.

• Always hold the gauge and regulator away from your face during engagement with the cylinder.

• Do not store CALGAZ cylinders with the regulator engaged in the valve. The regulator is not designed as the primary sealing mechanism.

• Before attaching a regulator to the 8AL or 2AL cylinder, ensure that the regulator is in the on position. Once the regulator is fully engaged in the cylinder, turn the regulator on/off knob to the off position until ready to sample. This procedure will help prevent air from being introduced into the cylinder and contaminating the reactive gas mixture.

• Do not over tighten the regulator when turning the regulator off. It will take a few seconds for the flow of gas to stop because of pressure being relieved in the regulator body. Over tightening will damage the regulator's seat.

• Keep your sampling system short and use compatible materials in the gas system. Teflon tubing works well in the majority of applications.

• Use properly maintained and specified regulators for the cylinders and gases in use. Avoid adapters to change gas service. Use only those accessories rated for proper pressure and gas service.
