This is a question from page 64 - click here to look up the answer

Quote From Page 89 Of The Illinois CDL Manual:

Placards are used to warn others of hazardous materials. Placards are signs put on the outside of a vehicle that identify the hazard class of the cargo. A placarded vehicle must have at least four identical placards. They are put on the front, rear and both sides of the vehicle. Placards must be readable from all four directions. They are 10 3/4-inches square, square-on-point, in a diamond shape. Cargo tanks and other bulk packaging display the ID number of their contents on placards, or orange panels or white square-on-point displays that are the same size as placards, and placed near the placards.

TruckingTruth's Advice:

It's good practice to grab an extra placard or two from the shipper in case one of your placards is blown off the truck during transport.

At a rest area you discover your hazardous materials shipments slowly leaking from the vehicle. There is no phone around. What should you do?
  • Make every attempt to contain the spill and locate the source of the leak
  • Find as many bystanders as possible to come assist you with cleaning the spill before it causes ecological damage
  • Secure the area, warn others of the danger, and send someone for help while you stay there
  • Drive the vehicle away from the public area, then walk to find a phone and call for help

Quote From Page 103 Of The Illinois CDL Manual:

If hazardous materials are spilling from your vehicle, do not move it any more than safety requires. You may move off the road and away from places where people gather, if doing so serves safety. Only move your vehicle if you can do so without danger to yourself or others.

Never continue driving with hazardous material leaking from your vehicle to find a phone booth, truck stop, help or other reason. Remember that the carrier pays for the cleanup of contaminated parking lots, roadways and drainage ditches. The costs are enormous, so do not leave a lengthy trail of contamination. If hazardous materials are spilling from your vehicle:

  • Park it.
  • Secure the area.
  • Stay there.

If you experience a truck fire while transporting hazardous materials, you should:
  • Before exiting the vehicle, if possible, take the shipping papers with you
  • Warn others of the danger and keep them away
  • All of these answers are correct
  • Keep the trailer doors closed
This is a question from page 75 - click here to look up the answer

Quote From Page 103 Of The Illinois CDL Manual:

You might have to control minor truck fires on the road. However, unless you have the training and equipment to do so safely, do not fight hazardous material fires. Dealing with hazardous material fires requires special training and protective gear.

When you discover a fire, send someone for help. You may use the fire extinguisher to keep minor truck fires from spreading to cargo before firefighters arrive. Feel trailer doors to see if they are hot before opening them. If hot, you may have a cargo fire and should not open the doors. Opening doors lets air in and may make the fire flare up. Without air, many fires only smolder until firemen arrive, doing less damage. If your cargo is already on fire, it is not safe to fight the fire. Keep the shipping papers with you to give to emergency personnel as soon as they arrive. Warn other people of the danger and keep them away.
