Explosion at Shreveport refinery involving hydrogen injured a worker

Release from pressure bottle followed by ignition and perhaps fast deflagration. Nine people affected, including the operator of the bottle.

The explosion occurred when an operator opened a valve on the hydrogen network of the plant. The operator suffered from a burn in the forearm and two other employees are shocked by the pressure wave…

Failure of a strainer allowed sand from brine filters to get into mercury cells in a chlorine plant. It appears that the sand obstructed flow and caused excessive hydrogen generation. An explosion…

The incident took place in compression room of methanol synthesis manufactory of ZAO Azot in Severodonetsk. As a result of pipeline destruction mixture of pressurized gases (mostly hydrogen) filled…

A hydrogen leak sparked a fire at a power plant, burning a 30-foot hole in the roof. Only one of the plants four turbines were shut down.

A hydrogen leak occurred on the hydrogen line of a hydro-desulfurization unit, followed by ignition . The failure was located on a supply manifold of the unit at a support beam. The unit was shut…

Hydrogen leaked from an analyser and ignited .On-site staff isolate the leak. As the leak was very quickly isolated, the amount of hydrogen released was negligible. Event no. 35501 of the French…

A detonation was heard and the hydrogen supply of the site was automatically shut down by the safety devices.The fire was caused by a hydrogen leak and led to the formation of a fireball at the end…

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 fire occurred on a flange of a hydrogen supply line to a desulfurization reactor unit of diesel, which leaked and ignited (30 cm flame) The leak was stopped by isolating the part of line…

A hot oil line (8-inch) in the hydro-desulfurisation (HDS) unit failed due to fatigue cracking. Hot oil at 50 bar and 343C sprayed across the roadway into the hydrogen units where ignition occurred.…

A hydrogen gas leak at an oil refinery ignited

Ignition of hydrogen produced by washing slag in a tank for chlorosulfonic acid.

A hydrogen jet fire occurred on a 25m3 tank while transferring a catalyst to a buffer tank. The constabulary created an area of safety around the plant while the staff extinguishes the fire by…

A leak of hydrogen gas, followed by an explosion, occurred when an engine was loaded with air, oxygen, and hydrogen, and then started for a preliminary ramjet engine combustion test. The engine was…

Due to unsealing of flange connection in a heat exchanger, hydrogen leaked and ignited. At 20 m height, under pressure of 0,25 MPa.

A hydrogen leakage caught fire in the hydrogen compressor area of the continuous reforming unit. The reforming unit and the hydrocracking unit were immediately stopped. The hydrogen flow was cut off…

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…
