Flashback arrestors used with oxyacetylene equipment are installed in which parts of the system?

Flashback arrestors stop flame from traveling back through hoses toward the gas sources, protecting regulators and cylinders from ignition. Since a flashback can occur on either the acetylene or the oxygen side, protection is needed on both lines to prevent flame from moving upstream in the system. Placing arrestors on both lines, typically right after each regulator or at the first hose connection, provides full protection and reduces the risk of damage or explosion if a flash occurs.
