What is a flashback?

• A flashback is an ignition of mixed gases in an oxy-fuel cutting and welding system.
• Are flashback arrestors and check valves the same?
• No. A check valve stops the reverse flow of gas; a flashback arrestor extinguishes a flashback fire.
• Smiths flashback arrestor with built-in check valve does both.
• Why do I need a flashback arrestor?
• Mixed gas explosions and flashback fires can result in damage to equipment and/or severe personal injury or death.
• Smith flashback arrestors with built-in check valves help prevent accidents caused by the reverse flow of gases and flashback fires.
• What is the minimum pressure required to allow gas to flow through the flashback arrestors?
• The built-in check valve requires a minimum of 2 psi to open allowing gas to flow through.
