The front passenger part of the semi-trailer was severely damaged, the co-driver was sent to the hospital for treatment, the driver was not injured. Nothing is known on the consequences of the hydrogen trailer.
- Emergency action
The situation risk of escalation was high, due to the possibility of explosion of the explosion of the hydrogen tanks. The fire rescue personnel first did a good job of on-site vigilance, using a water cannon to extinguish the fire of the semi-trailer, and at the same time keeping cool the hydrogen tanks . After about 1 hour of on-site monitoring and disposal, there was no explosion risk.
