AVENUE DES ARTS 3 … If a cylinder explodes it can cause: Travelling fireballs; Projectile hazards; Structural damage to near by buildings This paper considers the explosion of an acetylene gas cylinder, which occurred in 1993 in Sydney. [48] Information on safe storage of acetylene in upright cylinders is provided by the OSHA, [49] [50] Compressed Gas Association, [45] United States Mine Safety and Health Administration (MSHA), [51] EIGA, [48] and other agencies. Acetylene is an inflammable gas commonly used for welding in small-scale industries. Copyright © 2005 Elsevier Ltd. All rights reserved. Bonfire tests with fully loaded cylinders with 8.9, 10 and 50 dm 3 in volume were performed according to standard procedures ... Acetylene cylinders exposed to radiation from a remote fire. Fragments were found up to 200 m away (Fitzpatrick, 1993). Its lower and upper explosive limits in air are 2.5% and 93%, respectively. We present a case of a 34-year-old male welder who died following injuries sustained from explosion of an acetylene gas-welding cylinder. Acetylene is called D.A.— Dissolved Acetylene. The force of the blast caused damage to buildings and nearby equipments. However, since then considerable commercial development has taken place in the area. The Acetylene Gas Cylinder Explosion I 1993n., a n ex­ plosion occurre idn a suburb of Sydney causing the deat ohf a driver of a truck who was loading acetylene and oxygen cylin­ The force of the blast caused damage to buildings and nearby equipment. This combination thwarts decomposition, which generates heat and can lead to ignition and explosion. 1, Shane Wakefield. Flame or high temperature impinging on a localized area of the cylinder of this product can cause the cylinder to explode without activating the cylinder’s relief devices. Acetylene Storage. If a cylinder is involved in fire, the risk of explosion can last for up to 24 hours after the fire has been extinguished. The accident caused 23 deaths and 22 injuries. Carrying acetylene in vehicles Acetylene has an unusually wide explosive limit which means that even a small leak in an enclosed space can cause an explosive atmosphere to build up.

Acetylene gas expands to about 25 times of its own volume. Acetylene poses unique hazards based on its high flammability, instability and unique storage and transportation requirements. The cylinder is heated accidentally. Acetylene cylinders are a separate, dedicated and special type of cylinder that is used to store and transport the gas above pressures of 5 psi (.3 bar). Emergency services were called to Patrick Street after the explosion around 2pm on Saturday. There is any sign of smoke; There is an unusual smell with gas discharged. Protection Systems Against Explosions in the Gas Cylinder. Ignition can travel towards the cylinder but is normally stopped by the flash-back arrestor, which prevents decomposition of the acetylene or an explosion. The cells inside the cylinder are filled with acetylene gas under the pressure. CODE OF PRACTICE . If a cylinder has been transported, it must be left to settle in an upright position on arrival. The acetylene cylinder was not fully closed and began to leak. IF. Finely divided /cobalt/ metal decomposes and polymerizes acetylene on contact, becoming incandescent. result in fire or explosion. It consists of a steel shell containing a porous mass. Safety plug is provided to avoid explosion (Fig. The largest part shot through window and traveled One curious discovery of acetylene is on Enceladus, a moon of Saturn. Construction of Acetylene Cylinder. Due to the carbon-to-carbon triple bond, acetylene gas is fundamentally unstable, and will decompose in an exothermic reaction if compressed to any great extent. Fragments were found up to 200 m away. The acetylene cylinder was lying on its side and was feeding a mixture of liquid acetone and acetylene gas to the burner head. The acetylene gas cylinder explosion In 1993, an explosion occurred in a suburb of Sydney causing the death of a driver of a truck who was loading acetylene and oxygen cylinders at a transport yard. The acetylene cylinder valve should only be opened with a specific wrench and should be kept in place whenever the cylinder is in use. Acetylene is normally dissolved in a solvent, typically acetone, at pressures up to 19 barg (275 psig) at 20°C (68°F). Use a well-ventilated vehicle to transport acetylene. Many acetylene cylinders are collected and transported in unventilated vehicles. The contents gauge shows a pressure higher than 2750 kPa. Chemical Properties of Acetylene 3. Serious Injuries are Common Following Acetylene Explosions An acetylene explosion causes injury and even death to people and their pets from the force of the blast, falling or flying debris or shrapnel, and the flame. �p��dt This risk is magnified over prolonged storage periods. Natural acetylene is believed to form from catalytic decomposition of long-chain hydrocarbons at temperatures of 1,700 K (1,430 °C; 2,600 °F) and above. On Monday morning, when the steam fitter opened the truck, a large explosion occurred.
