The correct filling of the dewar canister and lng gas cylinder is one of the keys to ensure the safe use of gas cylinders. Improper filling of the dewar canister can often cause explosion accidents. The most dangerous and common accident is the mixing of oxygen and combustible gas. Or excessive gas filling.
The mixing of oxygen and combustible gas is often because when filling, the dewar can not be replaced, cleaned, etc., the original cylinder with combustible gas is used to fill oxygen, or the original cylinder containing oxygen When the combustible gas is filled, the combustible gas in the bottle reacts with oxygen chemically, generating a large amount of heat, which causes the pressure in the bottle to rise sharply, and the gas bottle breaks and explodes.
