What are flashback arrestors used for?

Flashback arrestors are crucial safety devices used in oxyfuel cutting operations to prevent flames from traveling back into the gas supply line. This function is vital because if a flashback occurs, it can lead to dangerous situations such as explosions or fires that can endanger the operator and damage equipment.

Flashback arrestors contain a flame trap, typically composed of a fine mesh or baffle that extinguishes the flame, as well as check valves that prevent the backflow of gases. They help maintain the integrity of the gas supply systems and provide a protective barrier, ensuring that the flames generated during cutting do not ignite in the gas supply lines.

In comparison, other options focus on enhancing operational characteristics, such as cutting speed or quality, but they do not address the primary safety function of flashback arrestors, which is the prevention of backfire hazards. Cooling down the cutting area is also unrelated to the primary purpose of these devices. Therefore, the use of flashback arrestors is essential for safe oxyfuel cutting practices.
