HIAD Facility - Application: Unknown
Employee used a small industrial vacuum cleaner on an unnamed process. During this process, hydrogen gas built up from a reaction between sulfuric acid and aluminum swarf. When the vacuum cleaner…
A large explosion happened in the contractor amenities area. The explosion was thought to be caused by an explosive mixture of air and hydrogen which existed in the pipes. The force of the explosions…
Explosion in generator area, thought to be hydrogen leak as a result of radial lead seal failure. Extensive plant damage.
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…
Hydrogen exploded in a compressor unit at a chemical plant, causing a fire.
In an electricity production plant, a hydrogen leak from a tank explodes forming a fireball. The explosion was in a turbine of one of the electric units (800MW each). The Unit is damaged.
A process operator was working in the collaring/ decollaring area of a mechanical workshop. An electric cross cut saw was used to make two diagonal cuts in the collar of a hydrogen cylinder before…
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…
Unit tripped on-load due to serious fire between alternator and number 12 bearing. Fire extinguished by fire brigade. No injuries. Serious site damage was sustained to in CT chamber and alternator…
A fire broke out on a heat exchanger in a hydrocarbons plant. The cause of the fire was leakage of hydrogen.
Lightning caused fires at plant near Hamburg after igniting a hydrogen mixture release through a ventilation pipe
This incident occurred at a linear alkylbenzene manufacturing plant. It affected dehydrogenation reactor of normal paraffin, during the operation of catalyst exchange in the reactor. This is usually…
A small quantity of hydrogen gas leaked out of a pipe and caught fire. The danger of an explosion was averted by the safety crew who put out the fire and switched the gas flow to an alternative line.
Weld failure caused a fire involving a hydrogen pipe at a fertilizer ammonia plant. Source of ignition was autoignition.
The accident occurred on the hopper fine powders from a pair of cyclones (the hopper is the bottom conical part of the cyclone collecting the powder/dust separated from gas phase). A bursting disc…
Severe hydrogen ingress into the stator coolant system resulted in a fire in the stator coolant head tank, ignition source unknown. No injuries to personnel. Minimal damage to plant.
A hydrogen generator overheated during testing and started a small fire in a power plant.
A man was burned when a fire broke out as a hydrogen cylinder was being changed in a governmental research centre. It was reported that the fire was started by a spark from a wrench. The sprinkler…
