HIAD Nature Event - Flame Type: Other
The event occurred during the decommissioning of a nuclear power plant. It involved a tank containing 100 kg of residual sodium from the decommissioned experimental nuclear reactor which was using…
Heavy rains (more than 600 mm in 1 day) had flood a factory manufacturing calcium core electrical conductors. The power supply was cut off. The water came into contact with the calcium stored in 150…
The event occurred in a silicon hydride (SiH) emulsion production process inside an enclosed production building. The process generated a flammable gas cloud gas ignited, which later ignited causing…
The event occurred at one of the unit producing iron powder, consisting of a furnace with a running belt for the powder, kept under hydrogen atmosphere to reduce and purify the metal. The hydrogen…
A gaseous mixture of hydrogen (H2), methane (CH4) and ethane (CH3-CH3) at 54 bar was cooled in a heat exchanger upstream of a hydrogen purification system. The accident started with a double…
Explosion, with consequent fire, in chemicals production plantThe accident occurred in the organo-metallic compound production unit, on a transport container for aluminum alkyls, which exploded…
The event occurred at a de-sulfurisation reactor unit. Hydrogen leaked into the reactor causing an explosion. The Fire spread rapidly.
on a Sunday morning, in a ceramic factory, a leak on a 100 m tank containing 370 kg of hydrogen caused an explosion. The generated pressure wave causes significant damage to exterior buildings (…
A hydrogen leak occurred on the a coolant pipe of an electrical generator located in the turbine building, at 200 m from the reactor. Because of the welding works ongoing at that moment on the pipe…
The event started at the effluent pipe of one of the hydro-cracking reactors, which broke and released a mixture of hydrogen, light gases (methane, butane), light gasoline; heavy gasoline; gas oil.…
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 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…
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…
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.
Employees were refilling a rack of 15 hydrogen cylinders that were connected together on a steel pallet with railings. A leak developed at a valve and the pressurized hydrogen ignited. Operations…
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…
A short circuit occurred in a bus bar system in a transformer building, causing a fire in adjacent switches. This was followed by the tripping out of the three refinery turbo-alternators, cutting off…
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 accident occurred on the hopper fine powders from a pair of cyclones (the hopper is the bottom conical part of the cyclone collecting the powder/dust separated from gas phase). A bursting disc…
