HIAD Causes: Installation Error
A hydrogen leak occurred on a sintering furnace in a manufactory of uranium pellets. The event happened during the restart phase after a period of maintenance. The hydrogen ignited at the location…
The boat was performing a drive test when one of the 280 lead gel batteries exploded and took fire. The local fire brigade was able to extinguish the fire but the above deck section of the boat was…
Around 4 a.m., a major leak occurred at the outlet of the diesel hydrodesulfurization furnace in a refinery. The goal of this unit is to lower the sulfur content of diesel fuels produced in other…
A fire occurred on a valve of a hydrodesulfurisation unit in a refinery. A cable gland was modified. Steaming wreaths are permanently installed.
Overpressure caused a cylinder head of a gas compressor to fail causing release of hydrogen followed by a fire during the start-up of the compressor after maintenance.
[NOTE: the sources are not completely clear in describing the system involved in this incident ; the following is the most plausible option according to HIAD validator]The explosion happened in two…
A shift supervisor received severe burns and later died after a flexible hose used to transfer hydrogen to the catalytic reformer was over-pressurised and caught fire.Hydrogen is supplied from three…
The event occurred in a support building at a test stand complex. The explosion destroyed two support buildings and severely damaged a large amount of equipment. No one was injured.Gaseous hydrogen…
An open backed truck was delivering various industrial gases to sites. At the site of the explosion a rack of argon gas bottles was being delivered to a laboratory in the building adjacent to the…
Release from pressure bottle followed by ignition and perhaps fast deflagration. Nine people affected, including the operator of the bottle.
In a laboratory, tests with hydrogen as aerospace rocket propellants were carried out. One of the experiments consisted in the generation of a vertical jet (turbulent regime) to determine the sound…
The event early on a Saturday morning, when the plant was thus practically empty. Nevertheless, the chronology of the accident can be reconstructed from the testimonies of the few operators who were…
A 2-inch line carrying hydrogen gas at approximately 2,800 psi (approximately 19.3 MPa) failed at a weld, resulting in a high pressure hydrogen fire. The fire resulted in flame impingement on the…
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…
Following the first flight of the Montgolfier brothers, the first severe accident with hydrogen on a Montgolfier-balloon occurred in 1785, when trying to cross the Channel from France to England. Two…
Early in the morning of (3:00 AM), the personnel on one of the companies on site reported a potential pipeline leak just south of the valve station. The potential leak was discovered due to bubbling…
A hydrogen release and subsequent fire occurred at meter station of a pipeline transporting hydrogen to a refinery. Local refinery emergency response team responded and secured the area. The pipeline…
A leak occurred on a relief valve of a high pressure hydrogen storage tank. No explosion or fire occurred.
A hydrogen leak occurs at on the hose connection of a tank truck being loaded into an industrial gas company. Alerted by the noise, the driver of the vehicle gave the alert. Firefighters from the…
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…
