The GAS CYLINDER pictogram is used to represent GASES UNDER PRESSURE. All compressed gases are hazardous because of the high pressures inside the storage cylinders. Gas can be released deliberately by the opening the cylinder valve, or accidentally from a broken or leaking valve. There have been many cases in which damaged cylinders have become uncontrolled flying projectiles, causing severe injury and damage.

The FLAME pictogram is used to represents FLAMMABLE gases, liquids, aerosols and solids. FLAMMABLE describes any solid, liquid, vapor, or gas that will ignite easily and burn rapidly.
