HIAD Facility - Location Type: Confined

The fire occurred in the hydrogen treatement unit of hydrodesulfurisation plant.

The fire occurred around 13:20 on three cells of the chlorine manufacturing unit. A leak of hydrogen in the electrolysis room was at the origin of the fire; the ignition of the H2 cloud caused a…

The incident occurred at a power generator during the shutdown of one reactor unit. Hydrogen leaked from the cooling circuit of the generator due to damaged sealing. The hydrogen ignited. The fire…

[NOTE: the attribution to hydrogen formation as cause of the explosion is 'probable 'but not fully demonstrated].Two explosions in two different sprinkler systems occurred, wit the same assumed cause…

Hydrogen leaked from the hydrogen compressor and ignited. The compressor was part of the desulfurization unit of a refinery. It had just been delivered and was under commissioning testing. The fire…

In a plant manufacturing chlorate products, a hydrogen leak occurred via the water drainage outlet onto the factory floor. Pressure in the hydrogen line increased because the hydrogen pipes were…

The event occurred in a bus garage when carrying out the purging process of the hydrogen cylinders. This process was executed via an electronic control system, but it was found that one cylinder…

Hydrogen release and explosion due to a leak in a high pressure hydrogen storage tank, during first start-up of plant.

A 50-litre standard hydrogen gas cylinder was temporarily placed and used in a laboratory. The hydrogen gas was used for a flame ionization detector (FID) in gas chromatography (GC) instrument. The…

Hydrogen release from a road truck transporting liquid hydrogen

At a linear accelerator site, a hydrogen retort exploded during ignition of burn-off gas. One employee experienced hearing loss in one ear and a shoulder injury from being blown into a cabinet. A…

The event occurred at a hydrogen tank, causing a flare and a displacement of air that threw the contract workers against the refinery's metal structure.The workers were using an electric rotary…

This resulted in the destruction of the building where the explosion occurred and claimed the lives of two people. The triggering event was a blowing out of a gasket in a water pump situated in a 100…

The laboratory works with soil bacteria that cannot survive in the presence of oxygen. As a result, research work is conducted inside a plastic chamber in which the chemical constituents in the air…

A hydrogen leakage occurred in the ammonia workshop of a plant manufacturing nitrogen products and fertilizer (classified SEVESO high threshold). It was detected by an operator in charge of safety…

The incident consisted of a leakage of potassium hydroxide solution (KOH) from an alkaline electrolyzer in a renewable hydrogen production plant. One webpage news reported that smoke formation…

A chemical mobile intervention unit intervened in the faculty to neutralize in an envelope sealed an experimental device likely to release hydrogen. The faculty was evacuated during the intervention.

The incident occurred during a temporary shutdown of the distillate hydro-treatement unit. The crude oil distillation units main column overhead product was pumped to a gasoline storage tank via the…

In a paper plant, an explosion occurs in a paper pulp tank while 2 workers were carrying out pipes cutting with a grinder on the roof of the tank. Detailed analysis of the event was performed by two…

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…
