An explosion occurred in a electrolyzer cell, the vent blew up and caused a pipe rupture on the low pressure chlorine pipeline. The event occurred when two operators were improving the tightness of…

The explosion occurred while starting up for the first time a hydrogenation reactor.The reactor was being commissioned, by performing tightness tests under hydrogen atmosphere at very high pressure.…

The soldiers of the Royal Prussian Air Ship Division stored large amounts of hydrogen gas. They kept some 1000 cylinders in a shed. On 25 May 1894 about 400 of them burst without apparent reason.…

The explosion occurred in a plant for the production of butter. It was due to the rupture of a hydrogen tank, during a sterilization process at high temperature (so-called UHT treatment). Two…

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…

(WARNING, UNCLEAR IF H2 WAS INVOLVED)The explosion occurred in a chemical reactor tank of a plant (SEVESO low level) manufacturing products for medical imaging. According to the investigation, the…

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…

This near miss occurred at metal smelting unit of a foundry. At 9:45 a.m., due to a power outage, the cooling pumps of two furnaces containing nickel and chromium stopped. One of the two furnaces…

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 event occurred at the chlorine drying towers. The towers, made of PVC, exploded suddenly and violently in a mercury amalgam cell chlorine plant. Because of failure of the electrical power system…

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 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…

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…

The explosion occurred in the compressors unit of the plant. Witnesses reported a cloud of yellow smoke and a fire ball at its bottom. This first event has been followed by a fire fed by a hydrogen…
