HIAD Nature of the Consequences: Fire

A malfunction in the turbine generator resulted in a fire and caused the operators to manually shut the reactor. The turbine generator transforms steam into electricity and hydrogen is used as a…

A hydrogen leak occurred on the hydrogen line of a hydro-desulfurization unit, followed by ignition . The failure was located on a supply manifold of the unit at a support beam. The unit was shut…

Hydrogen leaked from an analyser and ignited .On-site staff isolate the leak. As the leak was very quickly isolated, the amount of hydrogen released was negligible. Event no. 35501 of the French…

The hydrogen jet fire a pipe have been detected by a night operator which was making rounds in a solvent production unit. The unit's emergency response team managed the fire in minutes. Operators…

Three workers were working in the sulfur recovery unit (SRU), trying to restore the hydrogen flow. The workers were trying to isolate the cause of a flow problem: hydrogen was entering the…

A detonation was heard and the hydrogen supply of the site was automatically shut down by the safety devices.The fire was caused by a hydrogen leak and led to the formation of a fireball at the end…

The fire occurred in the hydrogen treatement unit of hydrodesulfurisation plant.

The fire occurred around 13:20 on three cells of the chlorine manufacturing unit. A leak of hydrogen in the electrolysis room was at the origin of the fire; the ignition of the H2 cloud caused a…

The fire occurred on a flange of a hydrogen supply line to a desulfurization reactor unit of diesel, which leaked and ignited (30 cm flame) The leak was stopped by isolating the part of line…

The incident occurred at a power generator during the shutdown of one reactor unit. Hydrogen leaked from the cooling circuit of the generator due to damaged sealing. The hydrogen ignited. The fire…

On February 3, 1994, a control room operator at Surry Power Station, Unit 1, observed pressure spikes on the pressurizer level instruments. At the same time, a loud rumbling sound was heard in the…

A hydrogen gas leak at an oil refinery ignited

A hydrogen jet fire occurred on a 25m3 tank while transferring a catalyst to a buffer tank. The constabulary created an area of safety around the plant while the staff extinguishes the fire by…

Due to unsealing of flange connection in a heat exchanger, hydrogen leaked and ignited. At 20 m height, under pressure of 0,25 MPa.

A hydrogen leakage caught fire in the hydrogen compressor area of the continuous reforming unit. The reforming unit and the hydrocracking unit were immediately stopped. The hydrogen flow was cut off…

Hydrogen leaked from the hydrogen compressor and ignited. The compressor was part of the desulfurization unit of a refinery. It had just been delivered and was under commissioning testing. The fire…

Leaking hydrogen gas ignited causing a fire at a power plant.

A fire was sparked by a hydrogen leak at a Goodrich plant around 9:50 a.m. Friday, safety officials said. "Apparently the hydrogen caused a fire when it hit the air," said Chief Alex Rodriguez of the…

In a hydrodesulfurization unit of a refinery, a leak on a hydrogen line ignited and damaged the surrounding lines, including one with acid gas. The weather conditions (fog and very little wind)…

Following the first flight of the Montgolfier brothers, the first severe accident with hydrogen on a Montgolfier-balloon occurred in 1785, when trying to cross the Channel from France to England. Two…
