Compressed gases are used throughout the 91Ö±²¥ÊÓƵ for both academic and trades purposes. Pure gases and gas mixtures are used in research as reactants, carriers and in lasers. Welding and refrigeration charging are typical industrial applications involving compressed gases.
Requirements for Compressed Gas Cylinders
- Cylinders must be handled as high-energy sources. Always transport cylinders with the safety cap installed and use a cylinder cart. Do not roll them by hand along the floor or transport them on forklifts.
- Always store cylinders upright and secure them using an approved lock-down device.
- Always use the correct pressure regulator for the specific gas.
- Do not store cylinders or lecture bottles with the regulator in place. If the regulator fails, the entire contents of the cylinder may be discharged.
- CGA fittings differ for inert gases (e.g., He, Ar, N2), flammable gases (e.g., H2) and oxidizers (e.g., O2, N20)
- Compressed gas cylinders, which contain acutely toxic gases, must be stored in a designated area
- All compressed gas cylinders must be clearly marked with the correct chemical name
- All cylinders should be labeled to indicate if the container is full or empty.
Propane Cylinder Safety
- Do not breathe the gas.
- Keep cylinders away from heat or ignition sources. Keep readily ignitable material at least 10 ft. away.
- Cylinder temperatures should not exceed 125 degrees F.
- Close the cylinder valve after each use and when empty.
- Secure cylinders to prevent from falling.
- Store and use in an upright position.
- Connect regulator with a properly sized wrench – do not use pliers
- Always turn the cylinder valve off after grill/heater burners have been shut off.
- Do not store cylinders indoors or in enclosed areas. Always store and use with adequate ventilation – outside of buildings.
- Avoid transporting cylinders in enclosed vehicles.
- Keep cylinder valve outlet plugged when not connected for use.
- Propane is heavier than air. Choose storage and use locations carefully so that if a leak occurs, gas will not settle in a low-lying area.
- There is no storage distance required from buildings if less than 125 lb. container.
