“…Dla porównania temperatura samozapłonu LPG sięga 287°C, a gazu ziemnego mieści się w przedziale 480-630°C. W przypadku zastosowania acetylenu w otoczeniu czystego tlenu temperatura płomienia wzrasta nawet do 3,300°C, a spalanie jest całkowite i zupełne (Jones, 1996;Leite, Ferreira i Carvalho, 1996;Jones, 1999;Ferrero, Beckmann-Kluge, Schmidtchen i Holtappels, 2010).…”

The purpose of this article is to present fire and explosion properties of acetylene, the requirements for storing and transporting this gas, and to present the results of tests conducted on single acetylene cylinders and on cylinder bundles. Hazardous area coverage during rescue operations involving acetylene cylinders in open areas should be at least 300 m. Care must be taken when handling rescue operations and all available safety measures should be used.

“…If the single acetylene cylinder is cooled for one hour and controlled for another hour without any signs of internal process, the destruction of the cylinder has not occurred. Results are described in the detail by Ferrero et al [15,16]. Attention has also been dedicated to the acetylene pressure cylinder in Poland.…”

Uncontrolled and Controlled Destruction of Acetylene Pressure Cylinders

The risk of physical destruction of a pressure cylinder increases with increasing temperature load. Acetylene is a significant hazardous gas in cylinders. If the destruction pressure is reached, the cylinder is torn into two or more pieces, followed by the gas release to the environment. The presence of ignition sources could lead to the formation of the fireball phenomenon. This phenomenon generally reaches approximately ten meters in diameter and can be accompanied by a blast wave and a spread of the cylinder’s fragments or surrounding objects. The consequences of this type of fire could be fatal. Shooting through the cylinder shell may lead to the mitigation, if not elimination, of the effects of the uncontrolled destruction mentioned above. As a result of the review of relevant publications, several states commonly use this method as a standard procedure. Internal gas is released through the resulting hole, the pressure drops down and the gas creates a fire jet or disperses to surroundings. This study is based on a large-scale experiment where acetylene cylinders were placed inside a prepared woodpile and exposed to fire. In the fire condition, the cylinders exploded and created fireballs, or were penetrated via shooting and created fire jets. The results from these tests were compared, focusing on the shooting procedure, then analyzed and discussed.
