Acetylene is an unstable explosive gas that is stabilised in the cylinder by dissolving it in acetone within a porous mass. The direct cause of the incident was a combination of an initiation event and the failure of the charcoal porous mass / acetone system to suppress that initiation.

Jan 29, 2007 · A demonstration of the explosive potential of even a small amount of acetylene mixed with the right amount of oxygen. Carleton University, Ottawa, Canada.

Feb 19, 2025 · Yes, acetylene gas is highly explosive and requires careful handling due to its chemical properties. Its use requires strict safety protocols that prevent potentially dangerous situations. In this guide, we explain what makes acetylene so highly explosive.

Flame and explosion limits for gases like propane, methane, butane, acetylene and more. The Flammable Range (also called Explosive Range) is the concentration range of a gas or vapor that will burn (or explode) if an ignition source is introduced.

Jun 1, 2006 · This paper considers the explosion of an acetylene gas cylinder, which occurred in 1993 in Sydney. The failure caused severe fragmentation of the cylinder and resulted in a fatality and property damage.

Nov 18, 2014 · Research was carried out into how ventilation in the rear of enclosed vans affects the build-up of acetylene gas. This provides essential information to those assessing the risk of carrying...

Although acetylene will not undergo combustion at concentrations above the UFL, it can undergo an explosive decomposition reaction, even at concentrations of 100%. NEVER USE ACETYLENE OR ITS EQUIPMENT IN ANY WAY NOT CONSISTANT …

5 days ago · The explosion of an acetylene pressure cylinder in an enclosed space exhibited a rapid sequence of physical explosions followed by a chemical explosion of the acetylene-air mixture. In the enclosed space, the explosion occurred as a volumetric explosion, generating a pressure wave on open surfaces. Part of the mixture burned outside the ...

Mar 19, 2025 · There was a small explosion and fire when crew were working on an oxy-acetylene system. What happened? Two engineers were setting up a new oxygen and acetylene cylinder for testing. They installed a flash arrestor and hoses on the cylinder, ensuring they were free from oil and grease.

Acetylene gas poses an additional hazard to other flammable gases as it is also reactive. Under certain conditions, even in the absence of any air or oxygen, it can decompose explosively into its...
