- Root causes
- Root CAUSE analysis
- The INITIATING CAUSE was a small collision causing a damage to a valve.
The ROOT CAUSE was the fact that the driver was not sufficiently careful in approaching the LH2 system fill point.

Lesson Learnt
- Lesson Learnt
- An operative procedure should consider the risk of collision and prohibit the backing the truck into position.
Physical barriers are required, to protect the pipes from damages, such as the ones coming from collisions.
