The glossary at the end of this section gives the meaning of the word “bulk.” Cargo tanks are bulk packaging permanently attached to a vehicle. Cargo tanks remain on the vehicle when you load and unload them. Portable tanks are bulk packaging which are not permanently attached to a vehicle. The product is loaded or unloaded while the portable tanks are off the vehicle. Portable tanks are then put on a vehicle for transportation. There are many types of cargo tanks in use. The most common cargo tanks are MC306 for liquids and MC331 for gases.
You must display the identification number of the hazardous materials in portable tanks and cargo tanks and other bulk packaging (such as dump trucks). Identification numbers are in Column 4 of the Hazardous Materials Table. The rules require black 100-mm (3.9-inch) numbers on orange panels, placards, or a white, diamond-shaped background if no placards are required. Specification cargo tanks must show re-test date markings.
Portable tanks must also show the lessee’s or owner's name. They must also display the shipping name of the contents on two opposing sides. The letters of the shipping name must be at least 2-inches tall on portable tanks with capacities of more than 1,000 gallons and 1-inch tall on portable tanks with capacities of less than 1,000 gallons.
The identification number must appear on each side and each end of a portable tank or other bulk packaging that holds 1,000 gallons or more, and on two opposing sides if the portable tank holds less than 1,000 gallons. The identification numbers must still be visible when the portable tank is on the motor vehicle. If they are not visible, you must display the identification number on both sides and ends of the motor vehicle.
Intermediate bulk containers (IBCs) are bulk packages but are not required to have the owner’s name or shipping name.
When hauling bulk hazardous materials, describe what a cargo tank is:
You must display the _______ of the hazardous materials in portable tanks and cargo tanks and other bulk packaging
The identification number must appear __________ of a portable tank or other bulk packaging that holds 1,000 gallons or more
Remember, greater than 1,000 gallons = all four sides. Less than 1,000 gallons = two opposing sides
