Summary
During recovery of an inflated lift bag aboard a vessel, an oxygen regulator broke off at the high-pressure bottle nipple. The king valve was closed and no harm occurred. Recommendations cover suitable fittings, protective framing and positioning regulators away from work areas wherever possible, with job safety analyses addressing bottles that must remain there.
