A conventional truck drove into a FCEV. The left rear side was damaged. There were no injuries and no hydrogen released. The car body needed to be repaired and the receptacle and the hydrogen tube…

The truck was carrying cylinders of nitrogen (N2), oxygen (O2), hydrogen (H2) and acetylene on a national road. It struck the right protection, then the concrete-reinforced central division, and…

Due to the road accident there was the formation of a fire that involved the hydrogen tube trailer and some other vehicles (involved in the incident).Moreover due to the crash there was the formation…

The HRS canopy was lower than the forecourt canopy. heavy duty vehicles were not noticing the issue and hitting the HRS canopy assuming same height.The canopy has now been repaired twice, and the…

A deflagration occurred during shutdown of a reactor used for ammonia synthesis. It was followed by a jet fire. The hydrogen leak was probably due first to the lower seals, followed by another leak…

In a chlorine electrolysis facility, a mixture of oxygen and hydrogen in one of the electrolyzer cells a short-circuit ignited causing a deflagration. The cover of the cell was a thin plastic film…

The safety cabinet with compressed hydrogen was located in a laboratory and used to supply hydrogen to an experimental facility. The safety cabinet was equipped with exhaust extraction. Due to a leak…

One of the two dispensers at a refuelling station for buses shutdown at a refuelling station. The dispenser company were called and confirmed there was an issue with the dispenser. The station…

This entry refer to a series of events occurred before the date given, which corresponds to the publication of the evidences at the Int. Conference on Hydrogen Safety 2015. The nozzle/receptacle…

This near miss occurred at a CHP plant operation with a SOFC. During the heating phase, the SOFC stopped due to the opening of the mainpower switch.This was due to a contact problem inside the SOFC…

The incident aoccurred ina biogas-fed Solid Oxide Fuel Cell Stationary system, working in CHP mode.A sudden stop of the biogas feeding line caused the safety shutdown of the plant (SOFC module).The…

A number of hydrogen-filled balloons burst into flames at a secondary school. About 1,500 small balloons to be used for the opening ceremony of a sport event exploded unexpectedly and caught fire at…

During the polymerization of ethylene in a 750 liters pressurized reactor, an exothermic runaway decomposition occurred and ethylene and its decomposition products were released through the two…

The explosion occurred while restarting the ammonia reactor. Synthetic gas (70% H2) was released at the flange of the relief valve of the turbo-compressor. The explosion was followed by a jet fire.…

The incident affected the raw material buffer tank (design pressure 0.38 MPa) of a diesel hydrogenation unit in a refinery. This buffer tank is located between the hydrogenation reactor and the raw…

The event occurred at one of the unit producing iron powder, consisting of a furnace with a running belt for the powder, kept under hydrogen atmosphere to reduce and purify the metal. The hydrogen…

Following the breakdown of a piston rod, a mixture of hydrogen and light hydrocarbons was released from the fresh hydrogen compressor of an oil refinery. The rod broke down because of stress…

An explosion followed by a fire occurs in a refinery, originated by a hydrogen release at the hydrogen compressor.

Plant own emergency response team was activated, assisted from local fire and emergency Services and regional Police. No one was injured during the incident and flames were brought under control…

A gaseous mixture of hydrogen (H2), methane (CH4) and ethane (CH3-CH3) at 54 bar was cooled in a heat exchanger upstream of a hydrogen purification system. The accident started with a double…
