HIAD Nature Event - Release Substance: Hydrogen

A researcher was conducting an experiment that involved sawdust being heated at pressure using hydrogen gas in an laboratory-scale autoclave.The gas leaked from the autoclave during the experiment…

The last flight of the Space Shuttle Challenger ended 73 seconds after the launch in an explosive burn of hydrogen and oxygen propellants that destroyed the External Tank and exposed the Orbiter to…

An explosion occurred on a hydrogen compressor due to an air ingress.The explosion projectiles damaged an ammonia storage tank with consequent ammonia release (domino effect) Three people were…

A crack occurred in a storage tank (300 kg of hydrogen) releasing gaseous hydrogen to atmosphere. The vapour cloud exploded with an apparent centre of explosion 9 m above ground, with a energy…

Hydrogen gas leaking from a tanker truck came in contact with a spark, causing an explosion at a semiconductor plant.

In an electricity production plant, a hydrogen leak from a tank explodes forming a fireball. The explosion was in a turbine of one of the electric units (800MW each). The Unit is damaged.

There was a massive explosion at one of the generator-turbine units of a coal-based power station. Undetected hydrogen leak from the generator was identified as a major trigger.According to the news…

The event started when a gasket in a water pump was blown out. The water pump was situated inside a 100 m long, 10 m wide, and 7 m high building. The pump was feeding water to a vessel containing…

The release and fire occurred during what appeared to be a normal operation in a reactor section of a Residue Hydrotreater Unit, when an eight-inch pipe connected to a heat exchanger failed at the…

A catastrophic failure of the low pressure turbine followed by fire and flooding severely damaged the generator. The main turbine automatically tripped due to an erroneous mechanical over speed…

Workers were connecting a compressed hydrogen cylinder, when a release of hydrogen occurred within a safety-box for flammable gases. During the emergency response procedures, the explosive atmosphere…

The event occurred during the disconnection of the hydrogen compressor for maintenance.Two deaths and three injured workers were the consequences. The cause(s) of the event are unknown.

A ruptured hydrogen line caught fire at a commercial gas plant.

The explosion occurred at a hydrogen fuel plant mainly serving hydrogen forklift fleets. The explosion damaged several nearby homes and could be felt nearly 10 miles away.Police and firefighters…

Two successive fires broke out in an interval of few minutes in four cells in the electrolysis room of a chlorine production plant. The technicians brought the fire under control using the fire-…

The fire started in a electrolysis cell. The fire originated from a hydrogen leak in the hydrogen over pressure control system of the cell and an unidentified ignition source. The ARIA report (sew…

A fire occurred in a hydrogen and catalyst loading lines of heavy oil unit. The most likely cause was that a hydrogen purge pipeline failure allowing hydrogen to escape. This mixed with hot oil…

At a nuclear power plant, a fire occurred in the station's hydrogen storage facility while the plant was operating at 100% power. The fire was reported to the control room by a non-licensed operator…

A technical failure in the High-Pressure turbine blades caused high vibrations in lubricating oil pipes. Some pipes broke off and the oil leak caught fire from hot surfaces. Also the generator's…

A small quantity of hydrogen gas leaked out of a pipe and caught fire. The danger of an explosion was averted by the safety crew who put out the fire and switched the gas flow to an alternative line.
