HIAD Causes: Job Factors

This incident occurred at the hydrogen production and storage unit of (probably) a power plant using hydrogen as a coolant of the turbine-generator system. Hydrogen was produced probably by water…

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…

A section of effluent piping ruptured on the Hydrocracker Reactor of a Refinery. A mixture of light gases (methane, butane), light and heavy gasoline, gas oil and hydrogen was released from the pipe…

The accident occurred in a disposal storage for contaminated waste, consisting in a 65-metre shaft flooded with seawater. At the origin of the explosion was the reaction with water of at least two…

The accident occurred in the Reactor 6 used to carry out the hydrogenation of a pharmaceutical intermediate.The operation of the plant was organized in two shifts. Since the hydrogenation at Reactor…

Workers were connecting a compressed hydrogen cylinder, when a release of hydrogen occurred within a safety-box for flammable gases. During the emergency response procedures, the explosive atmosphere…

The accident occurred during the maintenance of a sulfuric acid storage tank in an industry for the fertilizers production. The maintenance works consisted in cutting operations (to remove some…

Hydrogen gas leaking from drain pipes in a hydrodesulfurization plant: There was a hydrodesulfurisation plant which had a recycle hydrogen compressor fitted with a suction rectifier. Hydrogen gas…

During repairs of a heat exchanger in a benzene plant, a mixed gas (methane and hydrogen) contained in the cold box attached to the exchanger leaked and caught fire from a welding spark. The…

The fire started as a result of an explosion in the process section of a refinery. An open structure of steelwork protected with reinforced concrete housed the usual furnaces, reactors, heat…

A hydrogen leak occurred from a low temperature valve on an acetic acid plant. The leak ignited and the resulting fire burned for about an hour. There was considerable media attention, particularly…

At a nuclear power plant, a fire occurred in the station's hydrogen storage facility while the plant was operating at 100% power. The fire was reported to the control room by a non-licensed operator…

Lightning caused fires at plant near Hamburg after igniting a hydrogen mixture release through a ventilation pipe

A fatality occurred after a flexible hose used to transfer hydrogen to the catalytic reformer was over-pressurised and caught fire.On June 9, 1997, No. 1 and No. 2 hydrogen modules were connected to…

A jet flame occurred in a diesel distillation unit. It was caused by the release and ignition of hydrogen from the low-pressure (60 bar) section of a the unit. It occurred during maintenance works…

a gas leakage (approximately 70% hydrogen, 21% nitrogen and the rest carbon monoxide and other impurities) occurred at the connection between a temperature measurement casing and a flange in the…

A leak occurred on a 4 inch hydrogen main gas line which ran along a pipe bridge at the east end of a first stage compression plant building, ignited.The source of ignition was hot welding sparks…

A tube in a hydrorefiner heater ruptured resulting in an extensive fire inside and outside the furnace. The main fire in the furnace was extinguished within 15 minutes and the escaping gas / vapour…

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…

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…
