What is used in the acetylene tank to prevent it from exploding?

Acetone in acetylene cylinders helps stabilize the gas making it non-reactive within the cylinder. In this process, acetylene is dissolved in liquid acetone under high pressure.

What makes acetylene unstable?

Acetylene by nature is an unstable gas that has limitations. Acetone is added to acetylene cylinders to help stabilize the gas. The reduction of acetone can cause the cylinder to become unstable and dangerous.

Is it safe to lay an acetylene bottle on its side?

Do not lay acetylene cylinders on their sides. If an acetylene tank has accidentally been left on its side, set it upright for at least one hour before it is used.

At what PSI does acetylene become explosive?

Acetylene can also be explosive if the regulated pressure exceeds 15 psi (Pounds per Square Inch). Mixing acetylene with air, liquefying, compressing or heating the gas can also cause potential hazards.

Can you store oxygen and acetylene together?

Oxygen storage. Oxygen cylinders shall not be stored near highly combustible material, especially oil and grease; or near reserve stocks of carbide and acetylene or other fuel-gas cylinders, or near any other substance likely to cause or accelerate fire; or in an acetylene generator compartment.

Can oxygen bottles be laid down?

Liquid oxygen tanks should never be laid on their sides. Portable cylinders can be laid on their sides, but valves must be protected from collision. Tanks should never be placed in a tightly closed space like a trunk.

Which is safer propane or acetylene?

The flammability limit of acetylene in the air is 2.5\% to 82\%, whereas that of propane is 2.1\% to 9.5\%. This may lead to a conclusion that acetylene is more dangerous than propane; however, the same is not true. Acetylene’s specific gravity 0.9 so it is lighter than air. If gas leaks out it will rise.

Can acetylene tanks freeze?

d. Acetylene cylinders should always be stored upright, with the valve end in the upward position. In freezing temperatures, the pressure may drop within the cylinder to nearly zero and when flowed, acetone may leak from the cylinder resulting in clogging of downstream equipment such as a regulator.

Why are oxygen tanks explosive?

Due to the presence of oxygen, the fires burn very quickly and appear explosive. When the oxygen tank is opened, minuscule bits of debris get blasted up into the regulator with such force that they are heated to the point of ignition.
