A factory was evacuated after a tank began leaking hydrogen. No injuries were reported

An explosion at a hydrogen recovery plant resulted in the injury of 10 people.

A hydrogen tank exploded and caught fire at a chemical plant.

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.

The event occurred while starting a new production cycle. The production supervisor issued specific instruction on a new production cycle to a technician. The technician did not follow them in the right sequence as indicated in the verification instructions before staring production: to save time when pressurizing the device at 9 bar of nitrogen, he simultaneously made several adjustments and carried out several checks (opening the manual H2 valves of the storage tank, the emergency shutdown valve just in front of the workshops, etc.).
