- Acetylene cylinders must not be placed on their sides, since the acetone and binders will have dislodged.
- The result may be formation of an acetylene “pocket” that is subject to polymerization and the possibility that liquid acetone will be released into the regulator.
Thus, Can you 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. Do not try to refill a cylinder or mix gases in a cylinder.
Additionally Which is safer propane or acetylene? Acetylene will ignite at mixtures from 2.5 percent to 82 percent, while the range for propane is 2.1 percent to 9.5 percent. Based off of these numbers, it’s easy to argue that propane is much safer to use than acetylene. However, keep in mind that these are both flammable gases, and both need to be handled with care.
What happens when acetylene goes over 15 psi? Acetylene will not explode under low pressure at normal temperatures. However, it becomes unstable and spontaneously combustible when compressed to a pressure over 15 psi. Beyond 29.4 psi, it becomes self explosive, and a slight shock may cause it to explode even in the absence of air or oxygen.
Can you transport acetylene in a car? Use a well-ventilated vehicle to transport acetylene. Many acetylene cylinders are collected and transported in unventilated vehicles. In the event of a leak – no matter how minor – gas can build up in an unventilated vehicle and result in a fire or explosion. This risk rises over prolonged storage periods.
How long does acetylene need to be upright?
Acetylene cylinders must be transported and stored vertically. If acetylene cylinders have been found laying on their side, allow them to stand in an upright position for at least 30 minutes before use. Acetylene cylinders contain a porous mass and liquid acetone that dissolves the gas.
Can you use acetylene without oxygen?
Decomposition is a chemical reaction whereby acetylene breaks down into its constituent elements, carbon and hydrogen. This reaction gives out a great deal of heat, which can cause the gas to effectively ignite without the presence of air or oxygen.
What can be used instead of acetylene?
Propane and Apachi: this is used in oxy-propane cutting and brazing. It is often used as an alternative to acetylene when high cutting speeds and efficiencies are not required. Oxy- propane is widely used for preheating components.
What burns hotter propane or acetylene?
Acetylene releases almost 40% of its heat in the inner flame cone. Therefore, acetylene is better for cutting than propane. While temperature wise acetylene is hotter than propane the fact is that people are using propane for cutting incorrectly.
Is acetylene more explosive than oxygen?
oxidizer – oxygen or air. source of ignition – spark or high heat.

| Fuel Gas | “Lower Explosive or Flammable Limit” (LEL/LFL) (% by volume of air) | “Upper Explosive or Flammable Limit” (UEL/UFL) (% by volume of air) |
|---|---|---|
| Acetone | 2.6 | 12.8 |
| Acetonitrile | 3 | 16 |
| Acetyl chloride | 7.3 | 19 |

What happens when you lay an acetylene tank on its side?
Acetylene cylinders must not be placed on their sides, since the acetone and binders will have dislodged. The result may be formation of an acetylene “pocket” that is subject to polymerization and the possibility that liquid acetone will be released into the regulator.
Which gas is most explosive?
Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.
What is the most flammable gas?
1) Chlorine Trifluoride is the most flammable gas Of all the dangerous chemical gases, chlorine trifluoride is known to be the most flammable. It is a colorless and extremely reactive gas that can burn through concrete and gravel.
How safe are acetylene tanks?
Acetylene is highly unstable. High pressure or temperatures can result in decomposition that can result in fire or explosion. Acetylene cylinders must never be transported or stored in a closed vehicle.
Is it OK to lay down acetylene bottles?
Never store acetylene cylinders in an unventilated vehicle. Acetylene cylinders must be transported and stored vertically. If acetylene cylinders have been laying on their side, allow them to stand in an upright position for at least 30 minutes before use.
Can you haul acetylene tanks laying down?
Acetylene cylinders contain a porous mass and liquid acetone that dissolves the gas. If a cylinder has been transported or stored horizontally, it must be left to settle in an upright position for at least 30 minutes before use.
What is used in the acetylene tank to prevent it from exploding?
To prevent explosion acetylene gas is dissolved in liquid acetone for safe storage and usage. The cylinders are also filled with porous material that helps to suppress decomposition processes.
Do you turn off oxygen or acetylene first?
We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel.
