HIAD Quality Indicator: 2
An explosion in oil from a coal plant occurred as a gas unit which turns methane into carbon monoxide and hydrogen was being reactivated.
The naphtha and hydrogen gas leaked out from the gasoline reformer at the Southwest Petroleum as the relief-valve was operated after its repair.Although the source (Asian database ADRC) does not…
Explosion in condenser area two hours after the unit tripped (due to a stator earth fault). The stator earth fault had damaged two hydrogen cooler tubes, which allowed hydrogen to pass from the…
In a residual-oil hydrotreatment unit (also called residual oil hydrogenation) plant, a hydrogenation unit caught fire with a huge bang, followed by a fireball in the form of a mushroom cloud. Black…
A 7 inch thick reactor of a wide range hydrocracking unit being operated by computer at 2500 psi failed explosively due to localised heating. The blast caused widespread damage over a 300 yard radius…
Employees #1 - #3 were machinists that were in the process of trouble shooting a compressor which had hydrogen in the lines. No actual work was in process. They were only listening for obvious noises…
An explosion of unknown cause occurred at a hydrogen manufacturing plant. The explosion occurred on the second floor of the building, used by employees as a cafeteria and offices. The company where…
Fire in bulk hydrogen storage compound. Pressure gauge shut off valve spindle blown out (could be completely unscrewed and removed). The subsequent leak ignited by unknown source. No injuries…
A contained explosion in a hydrogen tank occurred at the thermal generation plant
Employee #1, a maintenance worker, was killed by a hydrogen blast while working inside a batch hydrogenation unit.
Hydrogen gas explosion blew the lid off a heavy container at a heat treatment and brazing plant, crushing one workers hand.
A gas mixture (25% nitrogen, 73% of hydrogen, 2% methane) leaked, due to the ejection of the check valve from its connection with the inlet pipe. A large amount of the gas mixed with air and ignited…

One employee was injured in an explosion in a chemical plant storage area containing ammonia, acetone, and hydrogen.
Explosion due to hydrogen gas leakage from an abraded pipe: A hole was made in a pipeline used for catalyst regeneration at an aromatics plant, ejecting catalysts and hydrogen gas which ignited.…
The event occurred at a de-sulfurisation reactor unit. Hydrogen leaked into the reactor causing an explosion. The Fire spread rapidly.
This incident occurred unit at a demonstration of a new technology for the catalytic cracking of vacuum residual oil. An oil storage tank failed due to high pressure. The overpressure in the tank was…
An explosion at a refinery started a fire that was fueled by diesel and hydrogen.
