- Description
A tube trailer carrying compressed hydrogen tubes was hit by car, without consequences.
- Event Initiating system
- Classification of the physical effects
- No Hydrogen Release
- Nature of the consequences
- Macro-region
- North America
- Country
- United States
- Date
- Component involved
- CGH2 tube (trailer)
- Failure mode
- damage, no release
- Initiating cause
- impact, rollover, crash
- Root CAUSE analysis
The INITIATING CAUSE was a traffic accident (collision).
ROOT CAUSE was a human error when driving.
This is a near miss. The collision did not cause any damage to the hydrogen system, because of sturdy construction of the trailer- Root causes

Zalosh et al (see references), concluded their analysis of hydrogen transportation accidents till 1978 with the following conclusions:
"Finally, an encouraging aspect of the transportation incident compilation is that 71% of the hydrogen releases did not lead to an ignition. ... The relatively few ignitions may be due to either to lack of ignition sources or to the rapid dispersal of hydrogen into the atmosphere. In any event, the accident data provide further incentive to transport , transfer and store hydrogen outdoors away from occupied areas."
