At 6 o'clock on May 9th, a Steyr semitrailer full of 23 tons of liquid ammonia reached the 1229KM+300M section of the Baiyang section of the Zhijiang National Highway No. 318 in Hubei Province. This was caused by improper handling of the car by the driver. After hitting the big tree next to the road, it fell off from the tank and the tank turned sideways in the middle of the road. Liquid ammonia loaded in the tank leaked at any time. After receiving an alert, the Zhijiang City Public Security Fire Brigade in Hubei Province quickly mobilized the force to rescue and rescue.

A large amount of diesel oil has leaked from the road surface, and a large number of detached steel plates are seen on the ground. After reconnaissance and inquiry, it was found that 23 tons of liquid ammonia was loaded in the tank and no leakage occurred. However, at this time, during the peak period of traffic, once it is hit and there is an open fire on the site, the liquid ammonia loaded in the tank will have the danger of leakage and explosion at any time, and the danger is imminent.
