Fire on a Bus While Refueling (1087)

The fire developed on a hydrogen bus during filling, and was detected due to the development of smoke and a smell of burned materials.The power cable of the compressor had overheated. Two are the possible causes: (1) the cable had been wrongly installed or fixed, or (2) the electrical system had caused too high current in the cable. The corrective actions have been:(a) To ship the affected component to the manufacturing company for inspection(b) To replacement of the affected component with a new one. (c) To perform an inspection of the system on all the other buses in function.

Manual isolation valves were shut to close in the segment and it was manually blown down. At 08:52 on of the day after the operator determined that the incident met reportable criteria and called the national response centre at 09:22.

Release from a Hydrogen Truck (1055)

A hydrogen leak took place on a trailer carrying compressed hydrogen, located inside the fenced perimeter of a hydrogen station.
