HIAD Nature Event - Ignition Source: Unknown

The vent occurred outside a fuel cells manufacturing facility. While preparing for transfer of liquid hydrogen from tanker truck to storage tank, a release of hydrogen occurred, which vaporized into…

A hydrogen leak occurred on the hydrogen line of a hydro-desulfurization unit, followed by ignition . The failure was located on a supply manifold of the unit at a support beam. The unit was shut…

Hydrogen leaked from an analyser and ignited .On-site staff isolate the leak. As the leak was very quickly isolated, the amount of hydrogen released was negligible. Event no. 35501 of the French…

Three workers were working in the sulfur recovery unit (SRU), trying to restore the hydrogen flow. The workers were trying to isolate the cause of a flow problem: hydrogen was entering the…

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…

The fire occurred around 13:20 on three cells of the chlorine manufacturing unit. A leak of hydrogen in the electrolysis room was at the origin of the fire; the ignition of the H2 cloud caused a…

The fire occurred on a flange of a hydrogen supply line to a desulfurization reactor unit of diesel, which leaked and ignited (30 cm flame) The leak was stopped by isolating the part of line…

A hydrogen fuel tank release caused a fire at an AC Transit fuel station, prompting authorities to, as a precaution, evacuate several businesses and a high school and to close a number of…

A hydrogen gas leak at an oil refinery ignited

A leaking hydrogen line exploded at an oil refinery.

The event occurred in a desulfurisation unit for heavy oil (hydro-cracking, Isomax process). The hydrogen release took place from one of the heat exchanges, after the restart of the unit. The reason…

Hydrogen leaked and ignited on a cell in the sodium chlorate (NaClO3) workshop of a chlorinated products plant.There were no victims and no damage to the environment. On-site firefighters controlled…

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…

A hydrogen tank exploded and caught fire at a chemical plant.

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…

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.…

A lorry crashed into a hydrogen tube trailer with considerable speed on the highway A1 near Cologne. The lorry driver was killed. Gas escaped from tubes and valves of three of the nine tanks and was…

An implosion/explosion occurred on a furnace in a company of copper metallurgy. The incident occurred at the end of the production cycle, when the furnace bell is lifted at the end of the cooling…

The fire took place during maintenance works in one out of the three gas extractors of the coke process line. Main cause was displacement of a flange which allowed the entrance of flammable mixture…

The laboratory works with soil bacteria that cannot survive in the presence of oxygen. As a result, research work is conducted inside a plastic chamber in which the chemical constituents in the air…
