HIAD Nature Event - Ignition Source: Static Electricity
The event occurred at one of the unit producing iron powder, consisting of a furnace with a running belt for the powder, kept under hydrogen atmosphere to reduce and purify the metal. The hydrogen…
An explosion followed by a fire occurred at a tar precipitator of gas treatment of a coke oven. The extractors were manually activated. Ten minutes later, the operator activates the internal…
An explosion occurred at a chlorine production plant during the restart of the installation. An hydraulic syphon had probably been blocked by fire extinguishing products following a previous fire on…
Hydrogen ignition during the (illegal) filling of a balloon.Two men had decided to fill in a weather balloon with hydrogen in a storeroom located in the basement of a block of flats. Their idea was…
The incident occurred in a catalytic reforming unit. At 13:41, a leak occurred at the 90 elbow of a pressure pipe containing a mixture of hydrogen and naphtha. This pipe was located between the pre-…
The incident occurred at a tank of the chlorine electrolyzer of a water treatment plantThe plant products were sodium hypochlorite as a disinfectant for water treatments. The production process used…
The loss of control of a reaction caused a fire in a pharmaceutical plant caused a reaction runaway and the rupture of a 6 m reactor. A cloud containing sodium borohydride and hydrogen was emitted.…
Hydrogen gas cylinders exploded at the same time in three industrial locations, when the opening valve was opened. The overpressure generated by the explosion caused the walls of the hydrogen…
This incident occurred at a linear alkylbenzene manufacturing plant. It affected dehydrogenation reactor of normal paraffin, during the operation of catalyst exchange in the reactor. This is usually…
Two mechanic workers had picked up a work permit for the removal of filters from a hydrogen line. An operator also visited the scene and answered the mechanics question as to whether the line should…
The accident occurred in a plant producing synthesized active ingredients for the pharmaceutical industry. An explosion and a fire occurred in one of the workshops of the plant. The chemical reaction…
An accident occurred prior to the performance of a hydrogen-oxygen balloon demonstration, seriously injuring the demonstrator, who suffered painful second-degree burns to his right forearm and had to…
A hydrogen car caught fire at a hydrogen fuelling station. During refuelling of a H2-fueled car the owner heard an abnormal noise and opened the fuel filler door to investigate. A small fire then…
In a laboratory, tests with hydrogen as aerospace rocket propellants were carried out. One of the experiments consisted in the generation of a vertical jet (turbulent regime) to determine the sound…
In a chemical plant (SEVESO), corrosion on the water side of a cooling exchanger caused water to enter the sulfuric acid and attack the steel in the tank. This reaction produced hydrogen that…
This accident happened on the SS66 road and involved a trailer transporting compressed hydrogen cylinders. The 50 l cylinders were in packages of 16 cylinders each. Due to the breaking of fixing…
