Talk to other people.

Attend hazardous materials training courses.

Guess.

Ask a police officer.

While the manual contains all of the information needed to pass the written exam for a hazardous materials endorsement, it does not contain all of the information necessary to do the job safely. You can learn more by attending hazardous materials training courses.

Roll the containers.

Load the containers by hand.

Use the vehicle’s emergency brake.

Ask someone to help you.

Containers of corrosive materials should be kept in their correct upright positions. They should not be dropped or rolled.

3 . Shippers must label hazardous materials. If an item is smaller than its label, how should the item be labeled?

The item may be tied together with other hazardous materials and labeled with a sheet of paper on the outside of the bundle.

The label may be attached to a tag that is securely attached to the package.

The item may be marked with a large orange dot.

The item may be placed in a box displaying a warning label.

Shippers must place diamond-shaped hazard warning labels on most packages of hazardous materials. If the label won't fit on the package, it can be placed on a tag that is securely attached to the package.

4 . When a driver is not in their vehicle, hazardous materials' shipping papers should be:

Kept on the driver's person.

Kept on the driver’s seat.

Kept under the passenger’s seat.

Placed on the dashboard.

Shipping papers for hazardous materials should always be easily accessible. When a driver is not in their vehicle, hazardous materials' shipping papers should be left on the driver's seat.

5 . When approaching a railroad crossing while transporting chlorine:

You must stop before crossing the tracks.

You must reduce your speed before crossing the tracks.

You can proceed without stopping if no warning lights are flashing.

You can proceed without stopping if no other vehicles are within sight.

If transporting any amount of chlorine, a driver must always stop at a railroad crossing 15 to 50 feet from the nearest track.

6 . If you are transporting explosives and your vehicle breaks down, you may notify other drivers:

With flares.

With electric lights.

By standing on the roadway and waving your arms.

By keeping the driver's side door open.

If your vehicle breaks down on the road while you are transporting explosive materials, you must warn other drivers. Put out warning signals like reflective triangles or electric lights if you are carrying Division 1.1, 1.2, or 1.3 explosives. Do the same if you are driving a tank used to transport Class 3 flammable liquids or Division 2.1 flammable gases, even if the tank is empty. If transporting flammable materials, do not use warning signals that could cause your cargo to catch fire.
