Burning his face and damaging his ear drum. This gives the liquid acetone time to return to its correct place in the porous mass. 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. We present a case of a 34-year-old male welder who died following injuries sustained from explosion of an acetylene gas-welding cylinder. The acetylene cylinder valve should only be opened with a specific wrench and should be kept in place whenever the cylinder is in use. The oxygen and acetylene cylinders were located on the quayside with the hoses rigged to the vessel. The plant was built in the 1920s when it was in quite a remote location. Acetylene is an inflammable gas commonly used for welding in small-scale industries. The experiment was carried out for three acetylene cylinders. I made an acetylene explosion in a 25 mL plastic graduated cylinder by dropping calcium carbide pieces into household hydrogen peroxide. 13, No. Acetylene can explode with extreme violence if the pressure of the gas exceeds about 100 kPa (≈14.5 psi) as a gas or when in liquid or solid form, so it is shipped and stored dissolved in acetone or dimethylformamide (DMF), contained in a metal cylinder with porous filling (Agamassan), which renders it safe to transport and use. Acetylene cylinders must never be transported or stored in a closed vehicle. 1, John Hodges. It consists of a steel shell containing a porous mass. Phil Hooker. Acetylene poses unique hazards based on its high flammability, instability and unique storage and transportation requirements. The characteristics of the failure morphology, which is entirely ductile, are discussed. The paper describes the failure and the circumstances surrounding it, examines the nature of the explosion which occurred and seeks an explanation of the events. This paper considers the failure of an acetylene gas cylinder which occurred under extreme loading conditions resulting in severe fragmentation of the cylinder. Accident Allert :Acetylene cylinder explosion A n operator was lighting an oxy/acetylene cutting torch. The incident occurred when the welder was ready to ignite the cutting torch head. Decomposition is caused by: Exposure to intense heat; Reaction to incompatible substances such as copper or brass 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). A member has reported an incident in which a sub-contractor’s oxygen and acetylene cutting hose burst and caught fire. Chemical Properties of Acetylene 3. If user experiences any difficulty operating cylinder valve discontinue use ... Assess the risk of potentially explosive atmospheres and the need for explosion-proof equipment. CODE OF PRACTICE . Acetylene is called D.A.— Dissolved Acetylene. Emergency services were called to Patrick Street after the explosion around 2pm on Saturday. The largest part shot through window and traveled Acetylene is an inflammable gas commonly used for welding in small-scale industries. There are several documented explosions that have occurred due to the buildup of acetylene vapors inside of a vehicle that were triggered by a spark from the vehicle’s electrical system. Acetylene Cylinder Risks. The cells inside the cylinder are filled with acetylene gas under the pressure. Its lower and upper explosive limits in air are 2.5% and 93%, respectively. Over the weekend the acetylene accumulated inside the truck. gaseous acetylene could collect. �p��dt Revision of IGC Doc 123/12 with editorial corrections. Acetylene and Its Uses 2. An explosion of the cylinder only three minutes after a flashback is extremely rare. Every year, fire and rescue services attend hundreds of fires and incidents involving acetylene cylinders. [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. A subcontractor was preparing to use an oxy-acetylene torch on the back deck of a vessel. Acetylene is so volatile it has to be dissolved in a solvent and stored with a porous mass to keep it stable. 2. The article describes a recent scene where the area around a farm had to be evacuated because it was discovered that there was an acetylene cylinder in a burning barn on the property. 1, Bill Geary. Fragments were found up to 200 m away (Fitzpatrick, 1993). IF. A gas cylinder at Greenock's Ocean Terminal exploded yesterday. Price, John William Howard. The contents gauge shows a pressure higher than 2750 kPa. At approximately 14.50hrs on Thursday 7th January 2010, an acetylene cylinder exploded whilst an employee was working on the filling racks at a dissolved acetylene (DA) bottling plant. If a cylinder is involved in fire, the risk of explosion can last for up to 24 hours after the fire has been extinguished. 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. 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. Because of the risk of explosion a hazard zone of 200 metres radius is set up every time these cylinders are in danger of exploding at a fire. Acetylene reacts with active metals (e.g., copper, silver, and mercury) to form explosive acetylide compounds. 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. There is no other recorded failure of this type in the modern history of acetylene cylinder traffic. Acetylene is normally dissolved in a solvent, typically acetone, at pressures up to 19 barg (275 psig) at 20°C (68°F). The failure caused severe fragmentation of the cylinder and resulted in a fatality and property damage. 705 - 715. If warmed in air or oxygen, or on impact, copper acetylides may explode in subsequent contact with acetylene. This combination thwarts decomposition, which generates heat and can lead to ignition and explosion. The paper presents results of experimental explosions of acetylene cylinders subjected to the impact of heat in a simulated fire. There are several There is any sign of smoke; There is an unusual smell with gas discharged. Use a well-ventilated vehicle to transport acetylene. The oxygen cylinder was nearly empty and the regulator had a cracked diaphragm. Hazards of acetylene cylinders There are a number of incidents each year where a flashback into an acetylene cylinder triggers decomposition, leaving the cylinder in a dangerous, unstable condition. This paper considers the explosion of an acetylene gas cylinder, which occurred in 1993 in Sydney. We present a case of a 34-year-old male welder who died following injuries sustained from explosion of an acetylene gas-welding cylinder. A too fast withdrawal may carry over solvent, leaving gaseous acetylene at high pressure or may cause static electricity sparks. The force of the blast caused damage to buildings and nearby equipments. Acetylene cylinders contain a porous mass and liquid acetone that dissolves the gas. Figure 3 Explosion of an acetylene cylinder . AVENUE DES ARTS 3 … All acetylene cylinders should be checked, using a soap solution, for leakage at the valves and safety fuse plugs. Acetylene is a moderately common chemical in the universe, often associated with the atmospheres of gas giants. Many acetylene cylinders are collected and transported in unventilated vehicles. Porous filler(8-10), Acetone(42), Acetylene gas(36), Reserve volume-70o F … Broken bones, missing fingers and limbs, as … Dissolved acetylene should not be withdrawn from the cylinder at an hourly rate greater than a value depending on the type of the cylinder and in particular its diameter. The cylinder is maroon-coloured; Oxygen (commercial) is contained in a black coloured cylinder. The largest part shot. Construction of Acetylene Cylinder. The characteristics of the failure morphology, which is entirely ductile, are discussed. There was a flashback to the acetylene cylinder, which started to vibrate. IF. The acetylene gas in the cylinder is dissolved in acetone which is absorbed by the porous mass. Three minutes later the cylinder exploded. Paper presented at the First International Conference on Engineering Failure Analysis (Lisbon, Portugal, 12–14 July 2004).

Instantly, there was a bang and flames were seen coming from a coil of oxygen and acetylene hoses on the deck. This produced acetylene and oxygen at the same time. Since there is no physical evidence remaining of how the failure occurred, the analysis concentrates on an evaluation of the most probable cause of the incident. Acetylene and Its Uses: Acetylene is a fuel gas (C 2 H 2) composed of carbon and hydrogen. A total of 13 bonfire tests were performed, as to provide data for the model validation. 2.2). 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 2006 ; Vol. Acetylene cylinders do not hެZ]o��+| result in fire or explosion. The incident occurred when the welder was ready to ignite the cutting torch head. The first is that the acetylene is mainly dissolved in liquid acetone, which at 15°C and 1.5 MPa can absorb 554 g of acetylene per kg of acetone. Specific and immediate action is required with any acetylene cylinder. IGC Doc 123/13/E . The cylinder becomes unduly warm. Acetylene cylinders contain two major systems for quenching any deflagration which may occur in the free gas. This video is of a scientific nature its purpose is to show and encourage to obey safety when handling gas cylinders. High pressure or temperatures can result in decomposition that can result in fire or explosion. 1, Shane Wakefield. There was a flashback to the acetylene cylinder, which started to vibrate. However, flash-back can occur when a flammable mixture remains in the blowpipe or hoses when the torch is lit. Acetylene cylinders must never be transported or stored in a closed vehicle. Decomposition of the acetylene is triggered by heat, eg when it is: The actual cause of this incident could not be established. Eight acetylene cylinders were exposed to a workplace fire and were assessed for pre-explosion leaks and metallurgical defects. The effectiveness of water cooling as a measure to prevent the burst of the cylinder is analyzed. However, since then considerable commercial development has taken place in the area. An explosion in Invercargill that left one man seriously injured was probably caused by a leaking acetylene gas cylinder that came into contact with an ignition source. I did it outside and the wind blew out my burning splint. Every year, fire and rescue services attend hundreds of fires and incidents involving acetylene cylinders. This paper considers the explosion of an acetylene gas cylinder, which occurred in 1993 in Sydney. A standard acetylene cylinder has a length of 30” (76.2 cm) and has a 10” (24.4 cm) diameter. The acetylene valve on the quad was slowly opened; the welder then opened up the oxygen and acetylene valves on the cutting head and ignited the tip. d�!��$ � 2 Health and Safety Executive, Redgrave Court, Merton Road, Bootle L20 7HS . ACETYLENE. The accident caused 23 deaths and 22 injuries. The cylinder is heated accidentally. The. If a cylinder explodes it can cause: Travelling fireballs; Projectile hazards; Structural damage to near by buildings This failure is outstanding in two respects: the violence of the failure which occurred and the fact that the explosion occurred where there were no apparent ignition sources present and several days, possibly weeks after filling. Once the fire has been extinguished, dissolved acetylene cylinders which have been involved in the fire need to be cooled for a total of 24 hours. Many acetylene cylinders are collected and transported in unventilated vehicles. According to Derby Telegraph, an acetylene cylinder explosion can create a "fireball of up to 25 metres and throw shrapnel up to 200 metres." Introduction The Acetylene Gas Cylinder Explosion. The accident caused 23 deaths and 22 injuries. The failure caused severe fragmentation of the cylinder and resulted in a fatality and property damage. The force of the blast caused damage to buildings and nearby equipments. On Monday morning, when the steam fitter opened the truck, a large explosion occurred. This risk is magnified over prolonged storage periods. 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 cylinder split into two parts. Acetylene can explode with extreme violence if the pressure of the gas exceeds about 100 kPa (≈14.5 psi) as a gas or when in liquid or solid form, so it … Acetylene Cylinder Risks Acetylene is so volatile it has to be dissolved in a solvent and stored with a porous mass to keep it stable. Acetylene gas may decompose explosively at elevated temperatures and pressures. EUROPEAN INDUSTRIAL GASES ASSOCIATION AISBL . 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 cylinder split into two parts. Finely divided /cobalt/ metal decomposes and polymerizes acetylene on contact, becoming incandescent.
