Gas welding equipment. Safety devices - Incorporating a flame (flashback) arrestor Ingestion-build-98192 Why should you use BSBS EN 730 1 specifies the general requirements and tests for safety devices for fuel gases and oxygen or compressed air incorporating a flame (flashback) arrestor used downstream of manifold, cylinder and (or) pipeline outlet regulators, and upstream of blowpipes for welding, cutting and allied processes. This standard does not specify the location of these devices in the gas system. Nor does it include requirements for safety devices which do not
