- Description
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.
- Event Initiating system
- Classification of the physical effects
- Unignited Hydrogen Release
- Nature of the consequences
- leak no ignition
- Macro-region
- Asia
- Date
- Component involved
- valve (generic)
- Failure mode
- rupture, no ignition
- Initiating cause
- impact, rollover, crash
- Root CAUSE analysis
The INITIATING cause was the high speed of the truck.
Although this seems to suggest a human error (not respecting of the speed limit for the application), the event could be also classified as an operation cause: why the safety design had not considered this anomalous event and provided preventing measures?- Root causes
