HIAD Causes: Management Factors

An explosion in oil from a coal plant occurred as a gas unit which turns methane into carbon monoxide and hydrogen was being reactivated.

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…

Two employees were working on a electric furnace under hydrogen atmosphere that had jammed. The furnace exploded. The employees sustained flash burns to their faces and were taken to the hospital,…

The explosion occurred at the hydrogen producing unit of a refinery.A solution of potassium carbonate was being drawn off from an absorption tower to a temporary storage tank for a turnaround…

On September 1, 1992, an explosion in this facility occurred due to an accidental release of hydrogen at the Institute of Energy Conversion, University of Delaware, US. Hydrogen gas was used in…

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…

Employee #1, a maintenance worker, was killed by a hydrogen blast while working inside a batch hydrogenation unit.

The day before the incident, the outlet pipe connected to methanation reactor started leaking gas, which contains hydrogen. The leak was temporarily eliminated by a pressurised plug. On the day of…

The event occurred in the steam condensing line of the residual heat removal system the nuclear reactor. Radiolysis generated hydrogen and oxygen which then accumulated in high concentration in the…

A hydrogen explosion had ruptured a pipe in the core spray system at the Brunsbttel BWR in Germany. Although the control room instrumentation had at the time indicated a leak of radioactive steam,…

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…

At a rubber factory, an explosion occurred inside a lubricant container filled with 18 tonnes of tri-(nonylphenyl) phosphite (TNPP or TNPA). This tank was typically stirred and maintained at 45C.…

An explosion occurred at testing facility of a space rocket engine. The incident occurred when executing a test studying the performance of a hydrogen gas flow measuring system for fuel feeding…

This incident occurred when subcontractor two workers were widening air vents on the roof of a building hosting a tank containing hydrogen chloride solution. This intervention was necessary to to…

The event occurred at a de-sulfurisation reactor unit. Hydrogen leaked into the reactor causing an explosion. The Fire spread rapidly.

A hydrogen-cooled electricity generator exploded inside a coal-fired power plant killing two workers and injuring fifty others. An investigation into the incident found that a hydrogen gas leak may…

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…

The incident affected at an indirect oil desulfurization unit, and originated at a piping at the outlet of a heat exchanger. The exchanger was located in the furthermost downstream of the reactor.…

The accident occurred in the cracking unit and in the sulfur recuperating system, more exactly in a 90 curve of a 8" piping. Due to the crack of the curve a mixture of flammable gases was released…

An explosion occurred a the Lurgi electrolysis unit of a chemical factory. The plant suffered extensive damage and one man died. The electrolysis plant produced hydrogen for process use and oxygen as…
