The pressure vessel in a chlorine separation system exploded after the corrosion of the steel process equipment allowed chlorine and hydrogen to mix and form a volatile mixture. The chlorine…
The accident happened in an anhydrous ammonia plant, commissioned in March 1977. Hydrogen accumulated inside a Benfield solution (hot potassium) storage tank and was ignited by a static charge, which…
This incident occurred at the hydrogen production and storage unit of (probably) a power plant using hydrogen as a coolant of the turbine-generator system. Hydrogen was produced probably by water…
Hydrogen gas cylinders exploded at the same time in three industrial locations, when the opening valve was opened. The overpressure generated by the explosion caused the walls of the hydrogen…
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…
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 failure of a high pressure hydrogen-based synthetic gas feed line to the ammonia converter produced a sudden explosion followed by a severe fire. One of the operators was fatally injured. The…
The cracking happened in an ammonia plant, started up in 1970, on the pipe leading hot synthesis gas from the synthesis convertor to the first heat exchanger. This pipe was affected by six cracks and…
Hydrogen enrichment of the gaseous phase in a rail tanker initiated an exothermic reaction between hydrogen and chlorine which in turn triggered fire of iron chloride.
In an chlorine production plant, vented chlorine and hydrogen, auto ignited when the hydrogen concentration was allowed to exceed 5% and the mixture mixed with air.
An isolation failure in starter coil of the high voltage generator induced an electric arc to the hydrogen supply line, with consequent fire and melting of the line.
The hydrogen release of a defect valve ignited due to an unknown cause. The fire caused the melting of soldered joint with consequence additional release of hydrogen at 6.2 bar, which contributed the…
The accident happened in a refinery unit, constructed ten years before. A pigtail ruptured in a steam reformer for the production of hydrogen, and caused a major fire, which destroyed most of the…
Due to the failure of a exhaust system, compressed hydrogen leaked into an area containing electrical components, with consequent fire.Leakage was allowed when exhaust system failed
The boat was performing a drive test when one of the 280 lead gel batteries exploded and took fire. The local fire brigade was able to extinguish the fire but the above deck section of the boat was…
Furnace tube leak caused excessive heat on H2 tube causing rupture
An accident occurred prior to the performance of a hydrogen-oxygen balloon demonstration, seriously injuring the demonstrator, who suffered painful second-degree burns to his right forearm and had to…
[NOTE: the sources are not completely clear in describing the system involved in this incident ; the following is the most plausible option according to HIAD validator]The explosion happened in two…
The event occurred in a support building at a test stand complex. The explosion destroyed two support buildings and severely damaged a large amount of equipment. No one was injured.Gaseous hydrogen…
The hydrogen buffer tanks that exploded were part of an experimental facility experimenting generation of renewable hydrogen from a water electrolyzer coupled to solar panels.The three hydrogen tanks…
