On 17 February 2000, THOR EMILIE was lost. The ship had been chartered by a Swiss company to carry about 2,000 tonnes of oxide zinc ore in bulk from Dunkerque in France to Porto Vesme on Sardinia.…
A short circuit developed in the wiring of a fire eye system on one of two 600 psig boilers serving a refinery. This triggered a rapid sequence of events that resulted in a one week shutdown of much…
In a plant producing calcium carbide (CaO + 3C -> CaC2 + CO), a dust collector clogged, probably due to the failure of the cleaning device (nitrogen nozzles) which allowed the dust to build a…
It was a small incident in a heat-electric power plant. The alarm was registered at 11:26 and the fire was extinguished at 12:03. The incident took place during tests using the reserve power…
A small hydrogen leak occurred during routine maintenance on an oil refinery unit not in operation.
Static electricity ignited hydrogen in a rising advertising balloon.
The event occurred just after that start-up steam was introduced into the reformer furnace inlet. At this moment an very high pressure and a single loud bang was reported by the operations personnel…
On may 23, 1984 between 8:50 and 8:55 pm, employee #1, a dye beam operator, was drawing concentrated sulfuric acid into a plastic pail. He added to this pail the contents of a "drip pail" which had…
An empty 100-m reservoir of sulfuric acid (H2SO4) exploded at 9:15 am at a chemical site. Installed directly above its retention basin at a height of several metres, this reservoir was projected and…
To repair a corroded flange on a 4500 liter sulfuric acid bowser outlet pipe, an angle grinder was being used to prepare the surface for welding. Within a few seconds of starting work there was a…
Syngas explosion at a university laboratoryThe university lab affected was investigating generation of hydrogen and methane from biomass (wooden chips). The experimental furnace was a concrete…
There was a small leak of syngas (a mixture mainly consisting of hydrogen and carbon monoxide) resulting in a localized fire at a bolted flange joint on the outlet carbon steel pipework of the High…
The leak occurred at the ammonia reactor after a technical shutdown of 4 days. When the production was resumed and the syngas compressor restarted 14 hours later, a jet-fire occurred. The Internal…
Following a trip caused by the safeguarding of an ammonia production line, the syngas released into the atmosphere and ignited.
The event occurred while re-starting the ammonia production unit after a technical stop, a synthesis gas (50% hydrogen, 17% ammonia, methane and nitrogen) leak ignited on a flange located just after…
A 24" pipe carrying synthesis gas (Hydrogen = 43.5%, Nitrogen = 14.08%, Methane = 0.2%, Carbon Dioxide = 12.3%, Water = 29.3% by volume) ruptured. About 60 kg of hydrogen contained in the gas…
Fire caused by leakage from tank. Gaseous hydrogen release in generator caused by turbine vibrations
3 workers were injured in the hydrogen explosion
The release of a blast furnace gas occurred at a section of pipework, due to the rupture of valve seal. The gas did not ignite and the fire service attended as a precaution. The gas was both…
Traffic accident with heavy rain.Four persons were killed when a pickup track collided head-on with a liquid hydrogen tanker in heavy rain.
Transport collision between hydrogen trailer and car, without hydrogen release. (R. G. Zalosh and T. P. Short, COMPARATIVE ANALYSIS OF HYDROGEN FIRE AND EXPLOSION INCIDENTS, Quarterly Report No. 2…
A truck conventional truck moved to another lane and did not see the FCEV. The collision caused a total loss to the latter.
Truck moving backwards hit a hydrogen and fuel cells bus and damaged its side mirror.
A vertical cylindrical hydrodesulfurisation reactor charge heater was being started up with hydrogen flow only rather than hydrogen plus oil as in normal operation. As a result of the low heat load…
A gaseous tube trailer gone off road in a countryside area and landed on one side. All cylinders were loaded to a pressure of 200 bars. The impact with the ground has caused the rupture of a high…
Two hydrogen explosions occurred at a boiling water reactor (BWR). The first explosion occurred at 9:30 a.m. and was mostly confined to the off-gas system. Damage was relatively minor.The second…

Employee #2 was using a torch to cut a U-bolt on the bypass piping next to a brine surge tank that potentially contained hydrogen gas in a vapour space in the upper portion of the tank. His job was…
At 17:30 on 5 may 2019, the pipeline operator was notified by a third party that there was a possible leak on its hydrogen pipeline, as identified by sound. Operator personnel arrived on the site at…
In the collective treatment plant of a chemical platform, the truck tank of 25 m containing hydrochloric acid (HCl) rose in pressure at 11 am; leakage of acid solution and gas evolution occurred in…
