HIAD Nature Event - Flame Type: Other
The event occurred on vent stack of an ammonia synthesis unit. The release of the gas was more specifically on the water purge line or the hydraulic guard of the vet stack. The process gas…
a hydrogen recycle compressor shut down unexpectedly, resulting in flaring activity with visible smoke.
A release of hydrogen occurred during the filling of a 28 bottles rack. A worker decided to move the rack from one station to another, due to works ongoing nearby. This movement, even though the hose…
A man was burned when a fire broke out as a hydrogen cylinder was being changed in a governmental research centre. It was reported that the fire was started by a spark from a wrench. The sprinkler…
During the isomerization of wax in a lube oil plant, the high pressure reactor ruptured, releasing its contents. The released gas ignited and a fire developed in the plant area where operators and…
A diesel and gas leak (H2, H2S, CH4) occurred in a hydrodesulfurization unit (2,200 t/d). The leak location was on one of the boiler valves of the stabilization column. The released mixture (390 C /…
An explosion and fire occurred at a reciprocating recycle hydrogen compressor during commissioning of a new Diesel hydrotreatement Unit. It happened during the reactor pre-sulphidisation step, when…
A shift supervisor received severe burns and later died after a flexible hose used to transfer hydrogen to the catalytic reformer was over-pressurised and caught fire.Hydrogen is supplied from three…
The fire broke out in the acid etching tank of the ferric chloride manufacturing unit of a SEVESO-classified chemical plant. In this tank, the attack reaction of the iron metal with hydrochloric acid…
The plant was operating at 92% power when a ground fault on a land steam exhauster caused the supply breaker to a motor control centre (MCC) to trip. This supply breaker could not be reclosed. The…
A hydrogen leak occurred on the hydrogen line of a hydro-desulfurization unit, followed by ignition . The failure was located on a supply manifold of the unit at a support beam. The unit was shut…
Hydrogen leaked from an analyser and ignited .On-site staff isolate the leak. As the leak was very quickly isolated, the amount of hydrogen released was negligible. Event no. 35501 of the French…
The event occurred in a desulfurisation unit for heavy oil (hydro-cracking, Isomax process). The hydrogen release took place from one of the heat exchanges, after the restart of the unit. The reason…
Hydrogen leaked and ignited on a cell in the sodium chlorate (NaClO3) workshop of a chlorinated products plant.There were no victims and no damage to the environment. On-site firefighters controlled…
The fire took place during maintenance works in one out of the three gas extractors of the coke process line. Main cause was displacement of a flange which allowed the entrance of flammable mixture…
An explosion or fire occurred in a hydro-treatment unit which was processing Fluid Catalytic Cracking feedstock. It was caused by a failure in a pipe downstream from a separator, resulting in the…
A severe fire in a hydrogen compressor building in a unifier unit of an oil sands refinery reportedly started in a 1,500 psi lube oil system. Fire fighting was difficult because of 40 degrees F…
