- Description
- A CGH2 tube-trailer lost control, left the roadway, and went into a 1 1/2 foot ditch, traveling approx. 50 feet in the ditch. The soft ground in the ditch caused the trailer to over turn, sliding approx. 10 feet and causing damage to 5 individual tube safety valves. The escaping hydrogen ignited, assumed due to the friction of the gas flow with the wall of valves. The fire engulfed the trailer, causing a total loss of the tractor and severe damage to the trailer. The total hydrogen content of the trailer was consumed by the fire.
