The explosion was followed by a fire. Eyewitnesses reported seeing a "huge gush of fire". The local fire and rescue team brought the fire under control.According to the company, the explosion was caused by a problem with a pipe that led to a fire involving a mixture of gases including hydrogen, nitrogen and ammonia. The two injured members of staff were treated for shock.

Following a trip caused by the safeguarding of an ammonia production line, the syngas released into the atmosphere and ignited.

The event occurred on vent stack of an ammonia synthesis unit. The release of the gas was more specifically on the water purge line or the hydraulic guard of the vet stack. The process gas consisting in 75% hydrogen, ignited. The fire could be extinguished the by the emergency decompression of the unit and the automatic shutdown of the synthetic gas turbocharger.

Fire in a ammonia plant.The accident starts with a leak of a hydrogen-nitrogen mixture at the suction flange of a compressor. The mixture ignites on contact with air and the fire spreads to an oil bath

An explosion occurred on a hydrogen compressor due to an air ingress.The explosion projectiles damaged an ammonia storage tank with consequent ammonia release (domino effect) Three people were injured.

The failure of a high pressure hydrogen-based synthetic gas feed line to the ammonia converter produced a sudden explosion followed by a severe fire. One of the operators was fatally injured. The failure of the feed line was characterized by a sudden rupture. There was no leakage prior to rupture. Portions of the piping shattered in a brittle fracture, which was produced due to a severe hydrogen attack. Extensive blisters were observed on the inside surface which failed.The initial crack probably originated at one of two small nozzles provided for temperature measurements.

In a chemical plant, a fire broke out on a hydrogen column of an ammonia manufacturing unit. The internal security service extinguishes the fire with powder and nitrogen injection. The unit was cooled with water.

Hydrogen leakage occurred on a pipe flange in an ammonia synthesis unit. A fire started immediately, which was taken under a control before the arrival of firefighters.

In an ammonia production unit, a 350-bar leakage of synthesis gas (ammonia + hydrogen) occurred in the compressor room. The leak was the result of the failure of a weld on a line (2") at the outlet of the compressor. A flammable cloud formed in the room (15 m x 105 m), 30 to 45 s later.

In a chemical plant , a process gas leak (4% ammonia and 88% hydrogen) occurs during a purge operation. The cloud of gas ignites and explodes. An employee is killed.
