- Description
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 fuel cells system had overheated.- Event Initiating system

- FCEV bus
- Failure mode
- fire (generic)
- Initiating cause
- conventional component failure (electricity, power)
- Root CAUSE analysis
The INITIATING cause was the overheating of an electrical cable during refuelling.
Two possible causes were proposed:
(1) the cable had been wrongly installed or fixed, or
(2) the electrical system had caused too high current in the cable.- Root causes
