HIAD Nature Event - Ignition Source: Unknown
The event occurred during the decommissioning of a nuclear power plant. It involved a tank containing 100 kg of residual sodium from the decommissioned experimental nuclear reactor which was using…
The event occurred in a silicon hydride (SiH) emulsion production process inside an enclosed production building. The process generated a flammable gas cloud gas ignited, which later ignited causing…
Leaking hydrogen ignited at a plant that processes bitumen from oil sands.
During chlorine-alkali electrolysis an accident occurred in which chlorine was released due to a chlorine-hydrogen explosion. The person charged with the control of the measurements was informed by…
A deflagration occurred during shutdown of a reactor used for ammonia synthesis. It was followed by a jet fire. The hydrogen leak was probably due first to the lower seals, followed by another leak…
The explosion occurred while restarting the ammonia reactor. Synthetic gas (70% H2) was released at the flange of the relief valve of the turbo-compressor. The explosion was followed by a jet fire.…
The incident occurred at a fuel cells manufacturing plant. The tanker was preparing to transfer liquid hydrogen to the company hydrogen bulk storage tank. During backing, it impacted an industrial…
A gaseous mixture of hydrogen (H2), methane (CH4) and ethane (CH3-CH3) at 54 bar was cooled in a heat exchanger upstream of a hydrogen purification system. The accident started with a double…
At the time of the incident, the desulfurization unit was shut down for scheduled cleaning of a cooling tower with reintroduction of a gas mixture into the system at a high hydrogen content. The…
The explosion occurred in a Litol benzene unit, when it was being restarted following a scheduled shutdown for maintenance. The explosion followed the release of about 30 kilograms of hydrogen gas…
The incident occurred in the hydrogenation Unit of a non-further specified chemical plant. Before the occurring of the event, a growing leak had been discovered in the vicinity of a circulation pump…
Explosion, with consequent fire, in chemicals production plantThe accident occurred in the organo-metallic compound production unit, on a transport container for aluminum alkyls, which exploded…
A fire in an oil refineryThe fire broke out together with an explosion noise from the heavy oil direct desulfurization system of the height of about 20 m. The fire burned a part of the system…
A violent explosion occurred at a blast furnace. The explosion occurred while the blast furnace was being cleaned at the end of casting. For this purpose, worker poured the contents of a casting…
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…
The event occurred at a de-sulfurisation reactor unit. Hydrogen leaked into the reactor causing an explosion. The Fire spread rapidly.
A hydrogen-cooled electricity generator exploded inside a coal-fired power plant killing two workers and injuring fifty others. An investigation into the incident found that a hydrogen gas leak may…
An explosion at a refinery started a fire that was fueled by diesel and hydrogen.
The accident occurred in the cracking unit and in the sulfur recuperating system, more exactly in a 90 curve of a 8" piping. Due to the crack of the curve a mixture of flammable gases was released…
The accident started with a leakage of distilled petroleum intermediate and hydrogen in the desulfurization unit of the distilled intermediate. Both substances ignited and exploded, with a later…
