A car was overtaking the bus and damaged its rear-left side

A hydrogen compressor had a major malfunction resulting in serious cavitations, vibrations and dead heading of the 1st stage. The incident resulted in 5 of the 8 lower head bolts on the first stage…

An employee was preparing a batch of glycol stearate emulsifier in a vessel. Upon completion of product, the quality control lab reported that the pH was too high and the product needed to be…

The incident occurred in a pharmaceutical plant. A disk ruptured on the vent of a reactor and the reaction mixture was projected onto a frontage of the synthesis workshop. It caused a spill of 700 l…

During chlorine-alkali electrolysis an accident occurred in which chlorine was released due to a chlorine-hydrogen explosion. The person charged with the control of the measurements was informed by…

The passenger car rolled down the road without driver and hit the hydrogen bus.

The driver of a hydrogen bus reversed into a post.There was some small material damage to the bus. No leakage of hydrogen (or other gases) occurred.

The bus drove into the garage and collided with a folded-out safety barrier. The upper corner of the roof was damaged. Also the first hydrogen tank was affected by the collision but without any…

high pressure spherical vessel, stress corrosion stressing by hydrogen, leakage along the weld, release of H2-CH4 mixture

Discharge pressure of a hydrogen compressor on a chloride plant fell to alarm level without any prior warning and simultaneously three bumps were heard.Smoke was seen coming from the hot motor…

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…

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…
