HIAD Quality Indicator: 2

A rollover accident involving a tanker truck carrying 12,000 gallons of liquid hydrogen forced the evacuation of nearly 50 homes.

Ejection of rotor wedge material lead to vibration induced failure of components, including hydrogen seals. Serious fire resulted from hydrogen leakage, which subsequently lead to an oil fire.…

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…

A severe fire in a hydrogen compressor building in a unifier unit of an oil sands refinery reportedly started in a 1,500 psi lube oil system. Fire fighting was difficult because of 40 degrees F…

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…

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.

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…

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…

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…

Fire caused by leakage from tank. Gaseous hydrogen release in generator caused by turbine vibrations

3 workers were injured in the hydrogen explosion

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…
