When filled with air, a tyre of a car suddenly exploded, and the car was burned out. The car illegally carried the hydrogen cylinders. Hydrogen leaked from the cylinders and was thought to be ignited by the static.

A minor fire broke out following a gas leak from hydrogen cylinders. A truck was returning to the base company after offloading hydrogen cylinders at a factory. The driver lost control and crashed against a pillar on a bridge over a river and overturned. Police brought a crane from to right the vehicle but as the lift started, the truck rolled backwards, the crane's wire rope snapped, damaging the valves on several cylinders and leaking hydrogen then caught fire. Fire and Rescue Service Personnel took more than an hour to extinguish the fire. The road was blocked for about six hours.

30 bottles with compressed hydrogen fell from a truck at a junction, because of speeding. The bottles started releasing hydrogen. Emergence team was called, and leak was stopped.

a hydrogen recycle compressor shut down unexpectedly, resulting in flaring activity with visible smoke.

A man was burned when a fire broke out as a hydrogen cylinder was being changed in a governmental research centre. It was reported that the fire was started by a spark from a wrench. The sprinkler system put out the fire within minutes. A four litre (one US gallon) container of hydrochloric acid was broken during the incident, but caused no injuries. Several containers of methanol in the same area were not affected. The building was evacuated. Canberra makes nuclear instruments.

A tank "filled with low-pressure hydrogen" exploded at a food manufacturing plant, killing three workers. The accident occurred when the workers were welding inside the tank after clearing hydrogen to install a hydrogen measuring device. The tank, seven metres high and two and half metres wide, was destroyed by the explosion. Police investigated the exact cause of the accident and suspected the sparks from the welding work caused the explosion with the remaining hydrogen inside the tank as the employees failed to completely remove the hydrogen before conducting the work.

The event occurred at a de-sulfurisation reactor unit. Hydrogen leaked into the reactor causing an explosion. The Fire spread rapidly.

An explosion or fire occurred in a hydro-treatment unit which was processing Fluid Catalytic Cracking feedstock. It was caused by a failure in a pipe downstream from a separator, resulting in the release and ignition of hydrogen and hydrocarbons in the unit area.

The fire occurred in the hydrogen treatement unit of hydrodesulfurisation plant.

A hydrogen leak occurred from a low temperature valve on an acetic acid plant. The leak ignited and the resulting fire burned for about an hour. There was considerable media attention, particularly from local radio. It was surmised that deterioration of the valves may have taken place shortly before the incident.
