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…
An explosion occurred caused by a leak of hydrogen from a reactor on a fertilizer plant. The blast hurled the head of a hydrogen gas converter 150m and sent it crashing through reinforced-concrete…
The accident occurred during the first phase of the batch synthesis of tricarbonyl compound (methylcyclopentadienyl) manganese (TMCM), while the reaction mixture in the reactor consisted of more than…
Employees were trying to open the manhole cover (600 mm diameter) of a hydrofluoric acid tank with a grinder, when an explosion occurred. The explosion was probably caused by the presence of hydrogen…
In a graphite purification workshop, the cooling circuit of an electric furnace leaks, the water decomposes in contact with materials heated to a temperature of 1,800C; the gas mixture (hydrogen,…
The boat was a 6.5 m semi-rigid electric-powered inflatable canoe, mainly used for greeting and directing pleasure boaters in harbour.It exploded without a flame shortly when an employee of the…
A fire occurred in a hydrogen and catalyst loading lines of heavy oil unit. The most likely cause was that a hydrogen purge pipeline failure allowing hydrogen to escape. This mixed with hot oil…
A deflagration occurred at a chemical plant during a synthesis operation involving sodium tri-acetoxy-borohydride inside a 5,300-litre reactor. Around 5:30 pm, the technician observed that the acetic…
The fire, 1 m high fire occurred in a pipe at the inlet of the hydrodesulfurisation unit of a refinery. The fire was caused by the leak of the pipe content, hydrogen and diesel fuel. According to the…
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…
A potentially explosive situation was reported by safety inspectors at a nuclear waste tank. The waste slurry had formed a thick crust which was trapping hydrogen being continuously generated…
A series of explosions at an oil refinery reformer unit caused by a rupture to an 8 inch naphtha and hydrogen feed pipe. The large number of injuries was due to the close proximity of a construction…
The operator detected a leak of aerosol hydrocarbons (diesel, hydrogen and hydrogen sulfide) in the diesel desulfurisation unit, causing a release of hydrogen and hydrogen sulfide at the top of the…
In a plant producing calcium carbide (CaO + 3C -> CaC2 + CO), a dust collector clogged, probably due to the failure of the cleaning device (nitrogen nozzles) which allowed the dust to build a…
In the collective treatment plant of a chemical platform, the truck tank of 25 m containing hydrochloric acid (HCl) rose in pressure at 11 am; leakage of acid solution and gas evolution occurred in…
