HIAD Nature of the Consequences: Fire

Fire on a filter of an autoclave. The event occurred in a plant for the production of plastics. After catalytic synthesis of amines, the filter of the autoclave was taken out for cleaning. During…

In a high pressure gas plant, hydrogen gas leaked through a flange on a non return valve located on a hydrogen inlet of a reactor. The leaking gas ignited.

The event occurred in an alkylation reactor. Due to the rupture of a pipe (probably due to material failure), a power failure took place and the plant was automatically put in hot-stand-by mode. This…

Follow a leak in a seal of a heat exchanger (metal-covered asbestos) a fire occurred in a reforming process. The hydrogen-rich mixture caused spontaneous inflammation. The fire lasted 30 minutes. The…

Firefighters used thermal imaging cameras to locate and extinguish a hydrogen fire at a silicon manufacturing plant.

The accident happened in a refinery unit, constructed ten years before. A pigtail ruptured in a steam reformer for the production of hydrogen, and caused a major fire, which destroyed most of the…

A short circuit occurred in a bus bar system in a transformer building, causing a fire in adjacent switches. This was followed by the tripping out of the three refinery turbo-alternators, cutting off…

Due to the failure of a exhaust system, compressed hydrogen leaked into an area containing electrical components, with consequent fire.Leakage was allowed when exhaust system failed

The accident took place in a tank-type pressurised separator on the synthesis gas line of an ammonia production plant. The pressurised separator operates at nominal values of 25 bar and 5C. It…

In a fertiliser plant, an ammonia synthesis unit stopped following the malfunction of an alternator (due to a thunderstorm). The safety features were operating normally, yet the synthesis gas (N2 /…

Fire in an ammonia plantA fire broke out in the hydrogen section of ammonia plant.

The fire was in a polyamide production chemical plant classified SEVESODuring maintenance of an isolated unit producing a polyamide monomer (LACTAME), a fire developed on the ground floor of the unit…

A fire broke out at a flange of a heat exchanger used in the catalytic reforming unit of a refinery. This exchanger makes it possible to heat the load of heavy oil and hydrogen by recovering the heat…

A fire occurred at an oil factory during maintenance work. On the day of the incident, a distillation unit was shutdown for a steam air tightness test. Cooling equipment on the distillation unit was…

A sudden fire started in the refinery's hydrocracking unit at the hydrogen compressor of re refinery (India).

A hydrogen skid was placed into service in a nuclear power plant, outside the controlled area. This skid, like seven others, was located in a gas cylinder storage facility. It was supplied by several…

An explosion occurred in the hydrogen washing tower of a chlorate plant caused by the breaking of the rupture diaphragms on the tower cover. The discharged hydrogen ignited, causing a minor leakage…

A fire started on the primary hydrogenation reactor of a chemical plant synthesizing alcohols and acids by reactions between olefins and a H2 / CO gas mixtures. The alcohols are synthesised in 3…

The accident originated in the isomerisation unit and propagated to the benzene saturation unit. The accident source was a mechanical rupture of one of the two compressors used to transfer hydrogen…

Severe hydrogen ingress into the stator coolant system resulted in a fire in the stator coolant head tank, ignition source unknown. No injuries to personnel. Minimal damage to plant.
