A rail carrier may accept and transport a hazardous material only if it is packaged, marked, labeled, placarded and documented as the HMR require, and must retain the shipping paper at the origin for one year. Part 174 requires inspection of placards and car condition at acceptance and at interchange (174.9), limits the handling of leaking packages, sets loading and unloading rules (174.55 to 174.67, including the attendance, brake and securement rules for tank cars during loading and unloading, and the 174.67 tank car unloading procedure), the train placement and segregation requirements (174.81 to 174.86, including the Subpart D segregation table), the rules for explosives (Subpart E) and for Class 2 and 3 tank cars and Class 7 (Subparts F to K), and the 174.14 movement of hazmat within 48 hours of acceptance. Carriers must also comply with the 172.820 routing duties.
