Evaluation of Small Quantities of Class 3 and Class 9 Hazardous Materials in Transportation

TRB's Hazardous Materials Cooperative Research Program (HMCRP) Web-Only Document 3: Evaluation of Small Quantities of Class 3 and Class 9 Hazardous Materials in Transportation identifies the commodities comprising Class 3 (Packing Group II and III) and Class 9 liquid hazardous material (HAZMAT) (UN 3082) to determine the risks of transportation of the HAZMAT in commerce by motor carriers. The research analyzes incident databases to discover patterns in the datasets, categorizes the failure causes of incidents and determines incident frequency, builds risk matrices for damages, and provides standard practices and procedures to reduce the likelihood and consequence of incidents involving Class 3 (Packing Group II and III) and Class 9 liquid HAZMAT.
