HIAD Causes: Material/Manufacturing Error

The event occurred in the continuous casting of hot metallic melt of the plant.Cooling water leaked through a crack in the cooling water inlet pipe of a secondary cooling line and directly into the…

The explosion occurred when an operator opened a valve on the hydrogen network of the plant. The operator suffered from a burn in the forearm and two other employees are shocked by the pressure wave…

Failure of a strainer allowed sand from brine filters to get into mercury cells in a chlorine plant. It appears that the sand obstructed flow and caused excessive hydrogen generation. An explosion…

The incident took place in compression room of methanol synthesis manufactory of ZAO Azot in Severodonetsk. As a result of pipeline destruction mixture of pressurized gases (mostly hydrogen) filled…

The sodium chlorate production unit had restarted after a maintenance shutdown phase. The mercury cells had been under nitrogen flushing since the beginning of the shutdown to avoid the presence of…

Hydrogen fire at a chlorine chemical production plant (Seveso-classified)Hydrogen ignited in a chlorine electrolyzer unit. The facility was shutdown. The staff of the unit, present on site, triggered…

A hydrogen leak sparked a fire at a power plant, burning a 30-foot hole in the roof. Only one of the plants four turbines were shut down.

A 2-inch line carrying hydrogen gas at approximately 2,800 psi (approximately 19.3 MPa) failed at a weld, resulting in a high pressure hydrogen fire. The fire resulted in flame impingement on the…

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…

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…

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…

A hot oil line (8-inch) in the hydro-desulfurisation (HDS) unit failed due to fatigue cracking. Hot oil at 50 bar and 343C sprayed across the roadway into the hydrogen units where ignition occurred.…

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…

A hydrogen fuel tank release caused a fire at an AC Transit fuel station, prompting authorities to, as a precaution, evacuate several businesses and a high school and to close a number of…

A hydrogen gas leak at an oil refinery ignited

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 leak occurs in a manufacture of steel pipes. The leak is detected and the alarm is triggered.

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

While making preparation for operation of a compressor supplying hydrogen to a heavy oil desulfurization unit, an operator got injured as the checking cover of a crank room came off, emitting a hot…

The event occurred in a bus garage when carrying out the purging process of the hydrogen cylinders. This process was executed via an electronic control system, but it was found that one cylinder…
