Summary
A shipboard oxygen hose exploded and caught fire when a cylinder valve was opened for cutting work. The replacement was a hydraulic oil hose, unsuitable despite its pressure rating. Adiabatic compression and residual oil were suggested as the cause. Lessons address hose specifications, oxygen-service cleanliness and slow valve opening.
