An explosion occurs during testing of the hydrogen feeding of an engine in the Spatial Agency Centre.

The rupture disk installed on a liquid hydrogen tank failed, in a plant producing organic chemicals, during the weekly shut down. The hydrogen ignited at the exit of the exhaust chimney. The fire and the gas release were stopped by simply closing a valve.

A leak occurred on the safety valve of a train wagon transporting liquid hydrogen wagon. The train was composed of 10 wagons. The train was stopped on the railway several hours to allow depressurization of the wagon. Train circulation was interrupted. A safety zone is set up and two gate-keepers are evacuated. Travelers travelled further by buses.

A liquid hydrogen leak occurs in a steel plant on a 42000 l tank of liquid hydrogen. A sealing coupling was installed to stop the leak.

A tank of liquefied hydrogen felt down in a chemical plant.The tank, containing 100 m of liquid hydrogen, was installed on a concrete plate, which failed. The hydrogen started leaking from the valve at the bottom of the tank. The operator declared the state of emergency and installed a safety perimeter. The emergency responders used a resin to close the leak, after which they defrosted and closed the valve.

An accident involving a truck hauling liquid hydrogen closed an interstate highway for two hours.

A road tanker carrying 125,000 cubic feet of liquid hydrogen caught fire when the tankers vent stack malfunctioned.The area within a one-mile radius was evacuated. No one was injured in the incident.

A tanker carrying liquid hydrogen overturned without rupturing. Traffic on an interstate highway was closed throughout the afternoon and evening.

A rollover accident involving a tanker truck carrying 12,000 gallons of liquid hydrogen forced the evacuation of nearly 50 homes.

The release occurred after the collision between a truck containing liquid hydrogen and a truck containing manganese dioxide on a highway.Due to the release, the traffic was interrupted for 4 hours and the safety system of the truck repaired.
