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…

The tanker crashed into the guardrail on a ring ramp leading to a highway. The tanker overturned, and the tank unit plunged more than 20 meters onto a road below.Witnesses reported multiple…

The incident occurred on a highway. The truck would have tried to avoid an obstacle fallen on the road. It so left the road, collided with the central guardrail and tipped over on the other side.…

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…

A release of a mixture of hydrogen, nitrogen and ammonia ignited and exploded in the ammonia synthesis unit. The release occurred on a flange of the heat exchanger. and was due to a crack on the…

An implosion/explosion occurred on a furnace in a company of copper metallurgy. The incident occurred at the end of the production cycle, when the furnace bell is lifted at the end of the cooling…

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 mixture of mainly carbon monoxide and hydrogen was released from a pipeline transferring process gases in a not further specified unit of a chemical plant, generating a flammable mixture which…

A 9000 gal (34 m3) LH2 storage tank exploded during repair of the vent stack. Few days before the explosion, the tank had been filled with LH2, but later on the hydrogen released and ignited at the…

A hydrogen explosion happened at a chemical plant in Cheshire, UK where 18 tons of hydrogen gas went up. The firefighters were on the scene tackling the fire quickly and efficiently.

A number of minor explosions occurred in the interrupter pot on a chlorine cell. No injuries or damage were reported.No previous explosion shad occurred which was taken to indicate that hydrogen…

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…

A series of explosions at an oil refinery reformer unit caused by a rupture to an 8 inch naphtha and hydrogen feed pipe. The large number of injuries was due to the close proximity of a construction…

A pipe rupture occurred in a steam condensing line of a residual heat removal system at the Hamaoka Nuclear Power Station Unit-1 (Hamaoka-1) during operation at rated power. The reactor was manually…

The nuclear plant was a boiling-water reactor with an output of 0.54 million kW. The component affected was a steam piping (inside diameter: 15 cm; thickness: 1.1 cm) of a heat exchanger used for…

The fire broke out on a worm ("vis sans fin") supplying a conveyor of aluminum. The ignition of the powder on the ground was caused by the flame cutting operation on the worm shell which generated…

The vessel affected by the incident was a gas storage used for the desulfurisation process. The desulfurization gas had high hydrogen content. The vessels had cracks in the upper transverse fillet…

In a chemical plant , a process gas leak (4% ammonia and 88% hydrogen) occurs during a purge operation. The cloud of gas ignites and explodes. An employee is killed.

A vertical cylindrical fired heater was used on the charge to a hydrodesulfurisation reactor. The flow was two phase at the heater inlet (hydrogen and hydrocarbon). The distribution of flow to the…
