The naphtha and hydrogen gas leaked out from the gasoline reformer at the Southwest Petroleum as the relief-valve was operated after its repair.Although the source (Asian database ADRC) does not…
Explosion in condenser area two hours after the unit tripped (due to a stator earth fault). The stator earth fault had damaged two hydrogen cooler tubes, which allowed hydrogen to pass from the…
In a residual-oil hydrotreatment unit (also called residual oil hydrogenation) plant, a hydrogenation unit caught fire with a huge bang, followed by a fireball in the form of a mushroom cloud. Black…
A 7 inch thick reactor of a wide range hydrocracking unit being operated by computer at 2500 psi failed explosively due to localised heating. The blast caused widespread damage over a 300 yard radius…
Employees #1 - #3 were machinists that were in the process of trouble shooting a compressor which had hydrogen in the lines. No actual work was in process. They were only listening for obvious noises…
Two employees were working on a electric furnace under hydrogen atmosphere that had jammed. The furnace exploded. The employees sustained flash burns to their faces and were taken to the hospital,…
An explosion of unknown cause occurred at a hydrogen manufacturing plant. The explosion occurred on the second floor of the building, used by employees as a cafeteria and offices. The company where…
The explosion occurred at the hydrogen producing unit of a refinery.A solution of potassium carbonate was being drawn off from an absorption tower to a temporary storage tank for a turnaround…
On September 1, 1992, an explosion in this facility occurred due to an accidental release of hydrogen at the Institute of Energy Conversion, University of Delaware, US. Hydrogen gas was used in…
Fire in bulk hydrogen storage compound. Pressure gauge shut off valve spindle blown out (could be completely unscrewed and removed). The subsequent leak ignited by unknown source. No injuries…
A contained explosion in a hydrogen tank occurred at the thermal generation plant
Employee #1, a maintenance worker, was killed by a hydrogen blast while working inside a batch hydrogenation unit.
Hydrogen gas explosion blew the lid off a heavy container at a heat treatment and brazing plant, crushing one workers hand.
The day before the incident, the outlet pipe connected to methanation reactor started leaking gas, which contains hydrogen. The leak was temporarily eliminated by a pressurised plug. On the day of…
The event occurred in the steam condensing line of the residual heat removal system the nuclear reactor. Radiolysis generated hydrogen and oxygen which then accumulated in high concentration in the…
A hydrogen explosion had ruptured a pipe in the core spray system at the Brunsbttel BWR in Germany. Although the control room instrumentation had at the time indicated a leak of radioactive steam,…
A gas mixture (25% nitrogen, 73% of hydrogen, 2% methane) leaked, due to the ejection of the check valve from its connection with the inlet pipe. A large amount of the gas mixed with air and ignited…
An explosion at a refinery Hydrotreater plant involving a furnace and hydrogen caused by faulty operation. Source of ignition was furnace.
Explosion accident while testing liquid water turbo-pump - A fire occurred during testing of a turbine pump which is a part of a rocket engine. On the day of the incident, seven seconds after the rpm…
At a rubber factory, an explosion occurred inside a lubricant container filled with 18 tonnes of tri-(nonylphenyl) phosphite (TNPP or TNPA). This tank was typically stirred and maintained at 45C.…
An explosion and fire occurred at a chemical plant applying silicone coatings. The blast occurred when some polymethyl hydrogen siloxane was accidentally fed into a reactor, together with the correct…
One employee was injured in an explosion in a chemical plant storage area containing ammonia, acetone, and hydrogen.
Explosion at styrene plant during start-up. A manhead flange failed in a light oil hydrogenation unit releasing 30 kg of hydrogen in a compressor shed. Ignition occurred in 10 to 15 secs.…
An explosion occurred at testing facility of a space rocket engine. The incident occurred when executing a test studying the performance of a hydrogen gas flow measuring system for fuel feeding…
This incident occurred when subcontractor two workers were widening air vents on the roof of a building hosting a tank containing hydrogen chloride solution. This intervention was necessary to to…
The explosion was followed by a fire. Eyewitnesses reported seeing a "huge gush of fire". The local fire and rescue team brought the fire under control.According to the company, the explosion was…
This incident occurred at the electrolyzer of a refuelling station. An employee of the electrolyzers manufacturer was on-site to conduct a reset of the plant power breaker system and to restart gas…
Explosion due to hydrogen gas leakage from an abraded pipe: A hole was made in a pipeline used for catalyst regeneration at an aromatics plant, ejecting catalysts and hydrogen gas which ignited.…
The event occurred at a de-sulfurisation reactor unit. Hydrogen leaked into the reactor causing an explosion. The Fire spread rapidly.
A hydrogen-cooled electricity generator exploded inside a coal-fired power plant killing two workers and injuring fifty others. An investigation into the incident found that a hydrogen gas leak may…
