9.1 – The Intent of the Regulations
9.1.1 – Contain the Material
Transporting hazardous materials can be risky. The regulations are intended to protect you, those around you and the environment. They tell shippers how to package the materials safely and drivers how to load, transport and unload the material. These are called "containment rules."
9.1.2 – Communicate the Risk
To communicate the risk, shippers must warn drivers and others about the material's hazards. The regulations require shippers to put hazard warning labels on packages, provide proper shipping papers, emergency response information and placards. These steps communicate the hazard to the shipper, the carrier and the driver.
