    • from the power unit.
  28. 28. If your placarded trailer has dual tires, how often should you check the tires?

    • Make sure your tires are properly inflated. Check placarded vehicles with
    • dual tires at the start of each trip and each time the vehicle is parked. The
    • only acceptable way to check tire pressure is to use a tire pressure gauge.
    • Do not drive with a tire that is leaking or flat except to the nearest safe place
    • to fix it. Remove any overheated tire. Place it a safe distance from your
    • vehicle. Don't drive until you correct the cause of the overheating.
    • Remember to follow the rules about parking and attending placarded
    • vehicles. They apply even when checking, repairing, or replacing tires.
  29. 29. What is a safe haven?

    33. Yes, you do, as explained below:


    • Stop before a railroad crossing if your vehicle:
    • • Is placarded, or
    • • Carries any amount of chlorine, or
    • • Has cargo tanks, whether loaded or empty, used for hazardous
    • materials.
    • You must stop 15 to 50 feet (4.6 to 15.2m) before the nearest rail. Proceed
    • only when you are sure no train is coming. Don't shift gears while crossing
    • the tracks.
  34. 34. At a rest area you discover your hazardous materials shipment is slowly leaking from the vehicle. There's no phone around. What should you do?

    a.) Park it.

    b.) Secure the area.

    c.) Stay there.

    d.) Send someone else for help.

    Contained below is a more detailed explanation of proper protocol:

    • 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 in
    • order to find a phone booth, truck stop, help or similar reason. Remember,
    • the carrier pays for the cleanup of contaminated parking lots, roadways and
    • drainage ditches. The costs are enormous, so don't leave a lengthy trail of
    • contamination.

    If hazardous materials are spilling from your vehicle:

    • • Park it.
    • • Secure the area.
    • • Stay there.
    • • Send someone else for help.

    When sending someone for help, give that person:

    • • a description of the emergency.
    • • Your exact location and direction of travel.
    • • Your name, the carrier's name and the name of the community or city
    • where your terminal is located.
    • • The proper shipping name, hazard class and ID number of the
    • hazardous materials, if you know them.

    • This is a lot for someone to remember. It is a good idea to write it all down
    • for the person you send for help. The emergency response team must know
    • these things to find you and to handle the emergency. They may have to
    • travel miles to get to you. This information will help them to bring the right
    • equipment the first time, without having to go back for it.
    • Never move your vehicle, if doing so will cause contamination or damage
    • the vehicle. Keep downwind and away from roadside rests, truck stops,
    • cafes and businesses. Never try to repack leaking containers. Unless you
    • have the training and equipment to repair leaks safely, don't try it. Call your
    • dispatcher or supervisor for instructions and, if needed, emergency
    • personnel.
  35. 35. What is the Emergency Response Guide (ERG)?

    • The Department of Transportation has a guidebook for firefighters, police,
    • and industry workers on how to protect themselves and the public from
    • hazardous materials. The guide is indexed by proper shipping name and
    • hazardous materials identification number. Emergency personnel look for
    • these things on the shipping paper. That is why it is vital that the proper
    • shipping name, ID number, label, and placards are correct.
