Oxy-acetylene torches have been used for many years for cutting, welding, brazing, and heating metals. 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. 

If your oxygen cylinder is low or empty, a reverse flow of gas may occur. The fuel gas, being at a higher pressure, can travel up the oxygen line and mix with gas in the hose, regulator, and cylinder. If you light your torch without purging the lines, a burn back may occur with explosions in the hose, regulator, or cylinder.

The flashback arrestor provides protection against backfire, flashbacks, and explosive mixtures in the gas supply.
