What device prevents the flame on an oxyfuel torch from flowing back to the bottles?

Flame Arrestor
Flash Arrestor
Blowoff Valve
Fume Hood

The correct answer is: Flash Arrestor

The device that prevents the flame on an oxyfuel torch from flowing back to the bottles is known as a flash arrestor. This important safety component is designed to stop flames that might accidentally travel back through the hoses and into the gas cylinders, where they could potentially cause explosions or other dangerous situations. Flash arrestors work by using metal mesh or baffles that cool down the flame and extinguish it before it can reach the source of the gas. Understanding the function of a flash arrestor is crucial for anyone working with oxyfuel systems, as it directly contributes to safe operation when cutting, welding, or brazing. Proper installation and maintenance of this device are essential to ensure that it effectively performs its intended function, helping to protect both the operator and the surrounding environment from fire hazards associated with pressurized gases.
