On a highway, a truck loaded with 400 gas cylinders crashed at night for an undetermined cause against a concrete wall and overturned. It slipped 150 m, before several 200 litre cylinders of hydrogen caught fire and set the truck on fire as well. The police stated that it was a large fire with detonations. The 400 gas cylinders were connected together and many of the cylinders had fallen out of their racks. In order to reduce the danger of further explosions, the fire-brigade cooled the gas cylinders with water for two hours. The highway remained closed for eight hours.

A hydrogen leak took place on a trailer carrying compressed hydrogen, located inside the fenced perimeter of a hydrogen station. According to the company managing the hydrogen delivery and refuelling station, the leak did not pose any risk to people or the environment. A preliminary assessment identified a faulty valve s source of the leak, but t was unclear a that time if it was a single defect or a systemic (i.e. design) problem.

A pick-up truck pulling a trailer carrying compressed hydrogen crashed in Ohio yesterday. The hydrogen leaked and ignited, producing flames ten metres into the air. The hydrogen quantity transported was 450 kg.

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.

A truck-trailer transporting 4,000 pounds (1800 kg) of compressed hydrogen burned to ground, including the driver cabin. The driver was able to get out before it got fully engulfed. 3- to 4-feet of flames were seen coming from the hydrogen tanks, the confinement of which, however, was not completely lost.Despite the absence of factual evidence due to the total loss, the authorities suspected that the initial fire feveloped in the engin. The heat of the engine fire impinged on the trailer, and caused the pressure release system to relase hydrogen.

The incident occurred on a highway. The truck would have tried to avoid an obstacle fallen on the road. It so left the road, collided with the central guardrail and tipped over on the other side. The tractor caught fire, then a leak on one of the bottles containing hydrogen (approximately 20 tubes) ignited and the fire propagated.A security perimeter was set up by fire fighters / authorities. The road, as well as the parallel roads, was cut in both ways of traffic. A diversion was organized. It was necessary to let the hydrogen burn and extinguish by controlling the fire.

A hose of a hydrogen tanker parked in at a specialised company ruptured. The released hydrogen ignited and exploded, followed by a fire probably fed by the continuously leaking hydrogen. The local fire rescue team rushed to the scene after receiving the alarm call. The fire was quickly brought under control and extinguished. Firefighters continued to cool the tank to avoid further problems. There were no casualties at the scene. There were two hydrogen trailers parked at the accident site. The other truck was not affected.

The tanker crashed into the guardrail on a ring ramp leading to a highway. The tanker overturned, and the tank unit plunged more than 20 meters onto a road below.Witnesses reported multiple explosions which could be heard up to two kilometres away. (Taiwan English News of 30 September 2020.)

The hydrogen leak occurred on a lorry travelling on a motorway. According to Highways England the vehicle was carrying nine cylinders of gas, one of which had a crack and was leaking. The only way to allow it to safely disperse was to let it vent.An exclusion zone was set up around it and the road closed. The incident led to delays of up to 90 minutes during rush hour.

A detonation was heard and the hydrogen supply of the site was automatically shut down by the safety devices.The fire was caused by a hydrogen leak and led to the formation of a fireball at the end of a hose at the conditioning station. A plant employee had just disconnected the hose sued for the filling of a semi-trailer. He did so to be able to change a non-return valve which was vibrating noisily. The hydrogen supply had been stopped, the automatic system had been switched to manual mode and the hose had been drained and disconnected.
