What is a compressed gas?
A gas that is under more than one atmosphere of pressure.

Hazard/Danger

explosive danger - gases under pressure

container could explode if heated/impacted

explodes if struck or heated; puncture/broken valve stem can turn cylinder into a “missile
frostbite (cryogenic) - gases have very low temperatures when released from cylinder
some gases have other hazardous properties:
- corrosive (ammonia)
- toxic (chlorine)
- flammable (acetylene, propane)
- asphyxiant - displaces oxygen (nitrogen)

Read all information on the label & the MSDS.
Check with your supervisor before using any new gas.
Inspect cylinder & valve stem for damage, leaks.
Keep cylinders in proper carriers - upright and secure.
Keep the protective cap on cylinders until ready to use.
Set regulator to correct setting for gas and application.
Store cylinders in cool, dry, ventilated place that is fire resistant and away from heat sources/high temperatures (>51.50C.)
Store cylinders of different gases separately.
Store empty cylinders separately from full cylinders & mark with “M.T.” or tag from supplier

Know safe operating procedures for the gas being used.
If using compressed gas cylinders - crack open cylinder valve slowly - stand to side of the regulators when opening the valve.
Close cylinder valve/regulator when not using.
Use in well ventilated areas.
