Two engineers setting up oxygen and acetylene cylinders experienced a small explosion and hose fire, leaving one with first-degree burns. The flash identifies inadequate flashback protection, bent hoses, faulty crimps, absent hot-work authorisation and unsuitable protective equipment. Lessons address arrestor placement and checking components after a flashback.
