- Root CAUSE analysis
The INITIATING CAUSE was rupture of a valve on one of the tube of a tube trailer. The ROOT CAUSE was the loss of control of the vehicle. The text in the source is unclear regarding the sequence of the incident following the development of a fire on one of the tube. Was the hydrogen release from the other tubes a manual intervention of the first responders, or automatically triggered by the increase of temperature due to the fire?
