Fire on a Hydrogen Tube Trailer Truck (1025)
A fire developed on a tube trailer transporting 330 kg of compressed hydrogen, while travelling on a highway. The fire was due to a pressure relief valve of a tube releasing hydrogen. The flames reached 10 to 20 m. The fire brigades were able to extinguish the file in 30 minutes.The truck had left a plant of hydrogen production and storage to deliver to a refuelling station. The probable origin of the incident is a fire on the tyres of the truck, which caused the overheating of the tubes, the increase of the internal pressure and the consequent opening of the pressure relief valve.
