- Description
- A compressed hydrogen trailer released accidentally hydrogen which ignited producing a hissing 60 jet flame.
It triggered the evacuation of a one-mile stretch. It was estimated that the tanker burned off about 32,000 cubic feet of hydrogen (ca. 75 kg) over a 2.5-hour period before the flame was extinguished.
The tanker contained about 100,000 cubic feet (ca. 230 kg) in 10 separate tubes. Firefighters climbed on the tanker truck during the incident to shut off the other nine tubes so their contents would not burn off as well. - Event Initiating system
