Summary
An oxygen–acetylene cutting hose burst and burned during torch ignition, without injuries. Inspection found brittle, perished hoses; an inoperative non-return valve was suspected, and connections had not been leak checked. The flash explains flashback hazards and recommends suitable leak detection, equipment inspection, correct lighting procedures and flashback arresters.
