Crash involving a Hydrogen Tube Trailer
Due to the road accident there was the formation of a fire that involved the hydrogen tube trailer and some other vehicles (involved in the incident).Moreover due to the crash there was the formation of a hydrogen jet-fire from one cylinder of the tube trailer (in proximity of the valve of the lowest cylinders) and a long longitudinal crack (about 10 cm) formed along one cylinder near the tube trailer back wheels.

Event Nature
Emergency Action
The rescue team cooled the tube trailer and extinguished the fire by a safe position (shielded by the guard-rail).Then the Chemical Fire Brigade Team used a thermo-camera to evaluate the presence of jet-fire from cylinders (it was noticed a jet-fire in proximity of the valves of the lowest cylinders) and to evaluate the temperatures and the possible deformations of the cylinders (it was noticed a long longitudinal crack, about 10 cm, along one cylinder near the tube trailer back wheels.The rescue team then decided to cool the deformation point with the maximum priority.
