Gas Cylinder Colour Code Chart
The gas cylinder colour code is indicative of the gas contained in the cylinder.
The gas cylinder colour code chart is designed to provide an instant visual cue identifying the contents for practical and safety reasons.
For example, without the cylinder colour code someone could accidentally misidentify a cylinder and give a medical patient an inert gas instead of oxygen, which could cause Inert Gas Asphyxiation.
Breathing any inert gas, like helium (Brown), nitrogen (Pewter) or argon (Peacock Blue), creates a dangerous absence of oxygen.
This could even be fatal. The gas cylinder colour code helps prevent this.
The gas cylinder colour codes also help prevent fuel gas (like acetylene) accidents that could result in fire or explosion.
