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 leakage caught fire in the hydrogen compressor area of the continuous reforming unit. The reforming unit and the hydrocracking unit were immediately stopped. The hydrogen flow was cut off, a protective combustion was carried out and the fire was completely extinguished after approximately 20 minutes, with no casualties. The cause of the accident is being investigated.

The incident occurred at company producing specialised products for aerospace and aeropwer applications. An employee was operating an induction brazing machine under hydrogen atmosphere when an explosion occurred.

a gas leakage (approximately 70% hydrogen, 21% nitrogen and the rest carbon monoxide and other impurities) occurred at the connection between a temperature measurement casing and a flange in the carbonization workshop cleaning tower. The leakage was reported to the plant leader, who issued the request to the workers to use iron cards and rubber plates to plug the leak. The operation failed and the leakage continued. At 17:00, at the request of the plant leader, the workers used a tire inner tube to wrap the leak.

In a residual-oil hydrotreatment unit (also called residual oil hydrogenation) plant, a hydrogenation unit caught fire with a huge bang, followed by a fireball in the form of a mushroom cloud. Black smoke began to billow up in the sky and was clearly visible from several kilometres away

An explosion of unknown cause occurred at a hydrogen manufacturing plant. The explosion occurred on the second floor of the building, used by employees as a cafeteria and offices. The company where the accident occurred mainly produces industrial hydrogen gas and supplies it in cylinders and trailers, as well as through pipe-line. The building was damaged and three people were seriously injured. The explosion shook the ground and caused nearby workers to evacuate.

An explosion occurred while inflating a balloon with hydrogen gas. The News reported the involvement of the hydrogen bottle.

Around 60 people gathered in a small theatre at a shopping centre to watch an array of scientific experiments, including a "small hydrogen explosion."Several children suffered second degree burns with children aged between five and 13 rushed to the nearest hospital.It remains unclear which chemicals were used in the experiments, with some reports claiming both hydrogen and alcohol-based chemicals were used.However a statement released by the Russian investigative committee examining the case said the science show had used "liquid nitrogen".The "flammable" substance was then ignited by the gas

An explosion and fire occurred at a hydrogen production plant serving the hydrocracker and the diesel hydroteater of a nearby refineryNo injuries were reported among the employees.According to the plant owner, the incident occurred in the collection manifold, also referred to as a collection header or a transfer line, due to the failure of an external carbon steel pipe of the collection manifold.
