At least one person was injured in an explosion at a theatre building. The investigation concluded that the accident has been caused by hydrogen entering the sprinkler room from the sprinkler piping…
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…
An explosion occurred in a electrolyzer cell, the vent blew up and caused a pipe rupture on the low pressure chlorine pipeline. The event occurred when two operators were improving the tightness of…
The explosion occurred while starting up for the first time a hydrogenation reactor.The reactor was being commissioned, by performing tightness tests under hydrogen atmosphere at very high pressure.…
A tank receives, after a negative reactivity test with the bottom supernatant of the tank, 20 m of methyl hydro-dichloro-silane, then 24 m of a mixture of oil and tar (negative reactivity test) and…
The explosion occurred in a plant for the production of butter. It was due to the rupture of a hydrogen tank, during a sterilization process at high temperature (so-called UHT treatment). Two…
A frontal road collision between a truck transporting pressurised hydrogen gas and a carBoth vehicles were projected into the fields, on each side of the road. No leakage of hydrogen gas was observed…
This near miss occurred at metal smelting unit of a foundry. At 9:45 a.m., due to a power outage, the cooling pumps of two furnaces containing nickel and chromium stopped. One of the two furnaces…
In a chlorine electrolysis facility, a mixture of oxygen and hydrogen in one of the electrolyzer cells a short-circuit ignited causing a deflagration. The cover of the cell was a thin plastic film…
The safety cabinet with compressed hydrogen was located in a laboratory and used to supply hydrogen to an experimental facility. The safety cabinet was equipped with exhaust extraction. Due to a leak…
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…
An explosion and fire occurred at around at a solid hydrogen storage company. The accident occurred while a press used to compact magnesium hydride and natural graphite into pellets was being…
A violent explosion occurred at a blast furnace. The explosion occurred while the blast furnace was being cleaned at the end of casting. For this purpose, worker poured the contents of a casting…
An explosion occurred at a chlorine production plant during the restart of the installation. An hydraulic syphon had probably been blocked by fire extinguishing products following a previous fire on…
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…
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…
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…
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.…
