At least one person was injured in an explosion at a theatre building. The investigation concluded that the accident has been caused by hydrogen entering the sprinkler room from the sprinkler piping, during maintenance of the building's sprinkler system. Together with indoor air, it formed a flammable mix of hydrogen gas and air. it is known that hydrogen forms in pipes due to corrosion of the pipe internal zinc coating by oxygen and water. The investigation could not identify the exact cause of the ignition.

The tanker truck was carrying nearly 13,000 gallons of liquid hydrogen. it hit the base of a light pole in the parking lot of a local grocery store as the driver was attempting to turn around. Hydrogen gas then began leaking out of it. This resulted in a valve on the truck to become damaged and could have caused the liquid hydrogen to be released from the truck, a very serious situation for nearby residents and businesses. Nobody was physically harmed by the incident.

A lorry loaded with gaseous hydrogen cylinders caught fire and shut a motorway.No one has been injured.

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 truck overturned and lost vacuum insulation. The hydrogen boiled and vented, but there was no ignition. The potential for fire or explosion, however, led to precautions that did cause considerable disruption: the interstate highway where the accident occurred was closed and nearby homes and businesses were evacuated.

This incident occurred in a unit processing vegetable oils and fats. A fire-brigade from the involved town was at the scene in a few minutes and was assisted by the Fire Department of a bigger city. Approximately one hour later the fire was extinguished. An employee of a contractor was injured when he fell from a scaffold, and two truck drivers were examined as outpatients. The results of the internal investigation is not publicly available.

The safety cabinet with compressed hydrogen was located in a laboratory and used to supply hydrogen to an experimental facility. The safety cabinet was equipped with exhaust extraction. Due to a leak, technical assistance had been requested from the fire department. The head of laboratory shut off the electrical supply to the laboratory. Measurements showed that there was no potentially explosive atmosphere in the laboratory room.

The explosion and fire happened in a diesel hydro-treatment unit used to desulfurise raw diesel be means of hydrogen.The facility was expected to begin full commercial operations later in 2020.

The event occurred at manhole cover of a of a pilot plant reactor where hydrogenation had been performed in a hydrochloric aqueous solution. The reactor had been flushed three times with nitrogen (i.e. nitrogen injecting at 3.2 bars and then relieving). An employee opened the manhole cover of the reactor to take a sample of the reagent. . After opening it, a minor detonation occurred.According to the DECHEMA database, the investigations found out these following causes:1.

An explosion and fire occurred at a 3000-gallon (approx. 11400 l) reactor, part of the production process of linear alkyl benzene (LAB), Process materials released from the various vessels and piping fuelled a subsequent fire that took approximately 2 hours to extinguish.As reported by Ali Reza (Ali Reza et al., 2007, see References), before the explosion, the bottom of the reactor was plugged with approximately 180 gallons (approx. 800 l) of a sludge-like mixture of coarse aluminum powder, aluminum chloride and various hydrocarbons.
