Most crash reports will only have space for recording one hazardous material. If there is a situation where a vehicle is transporting more than one hazardous material by class and/or Identification number, record the information on the material based on the following hierarchy.
- If there is a release, record the information on the material that was released.
- If there are hazardous materials from Table 1 and Table 2, record the material from Table 1.
- If there are multiple materials from Table 2, record the material that is present in the greatest quantity.
