The leak occurred on a 44 m vehicle of liquid hydrogen during a delivery to the unloading station of a steel plant. The truck drivers had connected the tank container to the fixed storage managed by a subcontractor, carried out a nitrogen sweep of the hose before cooling it, and were pressurizing the H2 before unloading when they saw a white cloud. The drivers closed the bottom valve of the container and the upstream and downstream valves of the heater before evacuating the area and sounding the alarm.

A liquid hydrogen leak occurs on one of the cylinders that a truck was carrying. After the leak was stopped, the vehicle was escorted by the fire brigade and taken to a laboratory for inspection.

A 40,000-litre capacity tanker lorry carrying liquid hydrogen tipped over into a ditch on a curve in an intersection while travelling on a municipal road at the edge of town. The lorry had just left a SEVESO-rated industrial gas production plant.The cistern was retained by an electrical tower and did not completely overturn. A whitish cloud dispersed through the degassing chimney on top of the cistern. First responders set up a 200-m safety perimeter and evacuate the neighbours. The containers internal pressure remains at approximately 0.1 relative bar.

At 11:15 pm, an explosion followed by fire occurred in the vicinity of the measurement transformer on an isolated 90,000 V electrical oil transformer at a plant manufacturing technical polymers. Plant personnel placed the installations in safe operating mode, while the backup line and 15,000 V transformer were activated, in coordination with the electric grid operator to keep the sites supply lines open. The risk of falling electrical cables led to closing the adjacent departmental highway, and the emergency crew installed a protective fire hose.

An explosion occurred at testing equipment of a fuel-feeding system for a space rocket engine. According to the original source of this event, now lost, the test envisaged a 42 MPa high-pressure hydrogen gas flow system, an exhaust gas duct outlet was damaged and hydrogen blew out and exploded. High-pressure hydrogen was flowing during the test, and burned not in the burner (a gas generator), but in a silencer tower after flowing through an exhaust gas duct.

A road transportation incident. A road tanker of hydrogen overturned and caught fire.

A fire occurred on a plant. The fire resulted from an escape of liquid hydrogen from a joint between an isolating block valve and a relief valve on one of the separation column preheater. The relief valve had been under repair and was being brought back onto line when the incident happened.An investigation team was appointed. The first task was to confirm that it was safe to resume operation in the section of the plant.

On February, 20, 1987, the Vogtle nuclear power plant reported a hydrogen leak inside the auxiliary building. This plant was recently licensed, had never been critical, and was in cold shutdown at the time of the event. The discovery of this problem was as a result of an unrelated event involving the activation of a chlorine monitor in the control building. When additional samples indicated no chlorine gas, the shift supervisor ordered further investigation into other plant areas.

A dual phase hydrogen tanker was expected to refil the storage of arefulein gstation for buses. Due to the failure of the a bolt of the tanker pump, the fefeulling could not take place. This resulted is that buses were unable to fuel for 3 days and loss of operations during this window. The faulty bolt was replaced.

To repair a corroded flange on a 4500 liter sulfuric acid bowser outlet pipe, an angle grinder was being used to prepare the surface for welding. Within a few seconds of starting work there was a bang and an eruption of white, or grey-yellow, smoke from the outlet pipe. The injured person (IP), who was angle grinding the pipe at the time, suffered deep burns to his right inner thigh. The IP was wearing shorts at the time of the incident. It appears the tanker had been used exclusively for the movement of 77% sulfuric Acid in the past.
