The equipment used today is safe, but every year, hundreds of employees are injured or die as a result of improper use. Knowledge and precautions can prevent fires and violent explosions. Gas Pressure: One cause of fires and explosions is high acetylene pressure. When more than 15 pounds of pressure is used, acetylene becomes unstable and decomposes explosively.

Nineteenth century examples of dry and wet types of flashback arrestors, for use with oxy-hydrogen. Flashback arrestors with different size and flow rate, and different connections A flashback arrestor or flash arrestor is a gas safety device most commonly used in oxy-fuel welding and cutting to stop the flame or reverse flow of gas back up into the equipment or supply line. It protects the user and equipment from damage or explosions. These devices are mainly used in industrial processes where oxy-fuel gas mixtures are handled and used. Flashback arrestors as safety products are essential to secure the workplaces and working environment. In former times wet flashback arrestors were also used.
Flashback Arrestors / Flame Arrestors
Fuel gases should not be used unless proper safety procedures have been understood and applied. Through the combination of established safety elements, flashback arrestors provide protection against flashbacks and backfire. The main reasons for flashbacks and backfire Very often the main reasons for flashbacks and backfire: faulty torch assemblies and incorrect gas pressures being used. In a backfire the flame burns back into the torch with a cracking sound. Either the flame is extinguished, or it is reignited at the nozzle opening.
