HIAD Causes: Management Factors

On 17 February 2000, THOR EMILIE was lost. The ship had been chartered by a Swiss company to carry about 2,000 tonnes of oxide zinc ore in bulk from Dunkerque in France to Porto Vesme on Sardinia.…

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…

The event occurred just after that start-up steam was introduced into the reformer furnace inlet. At this moment an very high pressure and a single loud bang was reported by the operations personnel…

On may 23, 1984 between 8:50 and 8:55 pm, employee #1, a dye beam operator, was drawing concentrated sulfuric acid into a plastic pail. He added to this pail the contents of a "drip pail" which had…

To repair a corroded flange on a 4500 liter sulfuric acid bowser outlet pipe, an angle grinder was being used to prepare the surface for welding. Within a few seconds of starting work there was a…

Syngas explosion at a university laboratoryThe university lab affected was investigating generation of hydrogen and methane from biomass (wooden chips). The experimental furnace was a concrete…

The leak occurred at the ammonia reactor after a technical shutdown of 4 days. When the production was resumed and the syngas compressor restarted 14 hours later, a jet-fire occurred. The Internal…

The event occurred while re-starting the ammonia production unit after a technical stop, a synthesis gas (50% hydrogen, 17% ammonia, methane and nitrogen) leak ignited on a flange located just after…

3 workers were injured in the hydrogen explosion

Transport collision between hydrogen trailer and car, without hydrogen release. (R. G. Zalosh and T. P. Short, COMPARATIVE ANALYSIS OF HYDROGEN FIRE AND EXPLOSION INCIDENTS, Quarterly Report No. 2…

Two hydrogen explosions occurred at a boiling water reactor (BWR). The first explosion occurred at 9:30 a.m. and was mostly confined to the off-gas system. Damage was relatively minor.The second…

Employee #2 was using a torch to cut a U-bolt on the bypass piping next to a brine surge tank that potentially contained hydrogen gas in a vapour space in the upper portion of the tank. His job was…

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…

Fire of drums containing lithium metal powder: Spontaneous combustion took place at drums containing lithium metal powder which were charged with argon gas for experiments. While lithium metal powder…

Fire following vapour explosion at a plant making titanium sponge due to design errors: A vapour explosion, followed by a fire, occurred at a drier in a plant making titanium sponge. When titanium…

The incident occurred during the verification operation of a new high pressure hydrogen generator. The electrolysis cell burned down, the pipes of the oxygen circuit burst and the peripheral…

Release from a welding of a hydrogen transmission pipeline At 12:45 pm the operation control centre (OCC) recognised that a customer flow and pressure dropped significantly. At 13:28 the OCC made the…
