HIAD Classification of the Physical Effects: Hydrogen Release And Ignition

The pressure vessel in a chlorine separation system exploded after the corrosion of the steel process equipment allowed chlorine and hydrogen to mix and form a volatile mixture. The chlorine…

Huge explosion of liquid chlorine mixed with hydrogen took place on pulp and paper plant in Arkhangelsk. More than 50 tons of liquid chlorine exploded.

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-…

During agricultural drainage work carried out by a farmer, an explosion occurred on a hydrogen pipeline located in a field. Flames several meters high were visible and two houses were evacuated. A…

A tank "filled with low-pressure hydrogen" exploded at a food manufacturing plant, killing three workers. The accident occurred when the workers were welding inside the tank after clearing hydrogen…

The 10 m3 hydrogen storage tank at the hydrogen station belonging to the oxygen plant exploded during production operation. The hydrogen storage tank was installed and used by the plant in 1995, with…

The event started at the effluent pipe of one of the hydro-cracking reactors, which broke and released a mixture of hydrogen, light gases (methane, butane), light gasoline; heavy gasoline; gas oil.…

The boat was a 6.5 m semi-rigid electric-powered inflatable canoe, mainly used for greeting and directing pleasure boaters in harbour.It exploded without a flame shortly when an employee of the…

The balloon had a 3.5m external diameter envelope made of anti-tear fabric (same techniques used in full sized balloons of the same company). The inner balloon was a meteorological balloon made of…

The accident happened in an anhydrous ammonia plant, commissioned in March 1977. Hydrogen accumulated inside a Benfield solution (hot potassium) storage tank and was ignited by a static charge, which…

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…

A researcher was conducting an experiment that involved sawdust being heated at pressure using hydrogen gas in an laboratory-scale autoclave.The gas leaked from the autoclave during the experiment…

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 serious chemical accident occurred at chemical industry producing olephins and phenols. The accident resulted in injuries to several workers and extensive damage to the plant, as well as minor…

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 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.…

3 people were killed when 18 hydrogen gas cylinders exploded.

The event occurred at a company producing machines for water treatment for the food industry.A pressurized tank exploded killing two workers and shaking windows and ceilings at neighbouring companies…

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…

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…
