You will place placards on hazardous material shipments based on the quantity and hazard class. In order to decide what placard(s) to use on the outside of the vehicle, what must you know?

  • The amount of all hazardous materials of all classes on your vehicle.
  • The material's hazard class.
  • The amount of hazardous materials being shipped by this particular shipper
  • You must know all three of these

Placard hazardous materials shipments based on the quantity and hazard class. You can decide which placards to use if you know these three things:

  • Material's hazard class.
  • Amount being shipped.
  • Amount of all hazardous materials of all classes on your vehicle.

Normally the driver will not have to figure out what placards to use. The shipper is responsible for determining which placards to use and will supply those placards for you.

One exception may happen if you make multiple hazardous materials pickups for the same shipment. Each shipper will know what placards must be used for their particular shipment, but they won't know what placards are needed based on the sum of all of your hazardous shipments. Your company will help you determine this. In 15 years of driving, I never ran into this situation, but it can happen.

If you discover a cargo leak, identify the hazardous materials leaking by using shipping papers, labels, or package location. Do not touch any leaking material — many people injure themselves by touching hazardous materials. Do not try to identify the material or find the source of a leak by smell. Toxic gases can destroy your sense of smell and can injure or kill you, even if they do not smell. Never eat, drink or smoke around a leak or spill.

You must have a Commercial Drivers License (CDL) with a hazardous materials endorsement before you drive any size vehicle that is used to transport hazardous material as defined in 49 CFR 383.5. You must pass a written test about the regulations and requirements to get this endorsement.

  • Bulk Tank Loading, Unloading and Marking
  • Driver Responsibilities
  • Driving and Parking Rules
  • Communications Rules
  • Emergencies
  • Loading and Unloading

Hazardous Materials Transportation - Shipper's Responsibility

The Shipper

  • Sends products from one place to another by truck, rail, vessel or airplane.
  • Provides correct placards.
  • Packages, marks and labels the materials, prepares shipping papers, provides emergency response information and supplies placards.
  • Certifies on the shipping paper that the shipment has been prepared according to the rules (unless you are pulling cargo tanks supplied by you or your employer).

The shipper also uses the hazardous materials regulations to determine the product’s:

  • Proper shipping name.
  • Hazard class.
  • Identification number.
  • Packing group.
  • Correct packaging.
  • Correct label and markings.

Carrier And Driver Responsibility

The Carrier

  • Takes the shipment from the shipper to its destination.
  • Prior to transportation, checks that the shipper correctly described, marked, labeled and otherwise prepared the shipment for transportation.
  • Refuses improper shipments.
  • Reports accidents and incidents involving hazardous materials to the proper government agency.

  • Placards vehicle when loading, if required.
  • Safely transports the shipment without delay.

Drivers must keep hazardous materials shipping papers in one of three ways:

  • In a pouch on the driver's door
  • In clear view within immediate reach while the seat belt is fastened while driving
  • On the driver's seat when out of the vehicle

Placards

Placards are used to warn others of hazardous materials. Placards are signs put on the outside of a vehicle and on bulk packages, which 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 at least 10 3/4 inches square, square-on-point, in a diamond shape.

Cargo tanks and other bulk packaging display the identification number of their contents on placards or orange panels or white square-on-point displays that are the same size as placards.

The Shipping Paper

The shipping paper describes a shipment. A shipping paper for hazardous materials must include:

  • Page numbers if the shipping paper has more than one page. The first page must tell the total number of pages
  • A proper shipping description for each hazardous material.
  • A shipper's certification, signed by the shipper, saying the shipment was prepared according to the regulations.

The Item Description

If a shipping paper describes both hazardous and non-hazardous products, the hazardous materials will be either:

  • Described first.
  • Highlighted in a contrasting color.
  • Identified by an "X" placed before the shipping name in a column captioned "HM.” The letters "RQ" may be used instead of "X" if a reportable quantity is present in one package.

Recognizing Hazardous Materials

Learn to recognize shipments of hazardous materials. To find out if the shipment includes hazardous materials, look at the shipping paper. Does it have:

  • An entry with a proper shipping name, hazard class and identification number?
  • A highlighted entry or one with an X or RQ in the hazardous materials column?
  • What business is the shipper in (e.g., paint dealer, chemical supply, scientific supply house, pest control or agricultural supplier, explosives, munitions or fireworks dealer).
  • Are there tanks with diamond labels or placards on the premises?
  • What type of package is being shipped? Cylinders and drums are often used for hazardous materials shipments.
  • Is a hazard class label, proper shipping name or identification number on the package?
  • Are there any handling precautions?

Placarding Rules & Regulations

Attach the appropriate placards to the vehicle before you drive it. You are only allowed to move an improperly placarded vehicle during an emergency in order to protect life or property. Placards must appear on both sides and both ends of the vehicle. Each placard must be:

  • Placed so the words or numbers are level and read from left to right.
  • At least 3 inches away from any other markings.
  • Kept clear of attachments or devices such as ladders, doors and tarpaulins.
  • Kept clean and undamaged so that the color, format and message are easily seen.
  • Be affixed to a background of contrasting color.
  • The use of “Drive Safely” and other slogans is prohibited.

The front placard may be on the front of the tractor or the front of the trailer. To decide which placards to use, you need to know:

  • The hazard class of the materials.
  • The amount of hazardous materials shipped.
  • The total weight of all classes of hazardous materials in your vehicle.

Parking a Placarded Vehicle Not Transporting Division 1.1, 1.2 or 1.3 Explosives

You may park a placarded vehicle (not laden with explosives) within 5 feet of the traveled part of the road only if your work requires it. Do so only briefly. Someone must always watch the vehicle when parked on a public roadway or shoulder. Do not uncouple a trailer and leave it with hazardous materials on a public street. Do not park within 300 feet of an open fire.

  • Be aware of the hazards of the materials being transported.
  • Know what to do in emergencies.

Hazmat Route Restrictions

Some states and counties require permits to transport hazardous materials or wastes. They may limit the routes you can use. Local rules about routes and permits change often. It is your job as driver to find out if you need permits or must use special routes. Make sure you have all needed papers before starting.

If you work for a carrier, ask your dispatcher about route restrictions or permits. If you are an independent trucker and are planning a new route, check with state agencies where you plan to travel. Some localities prohibit transportation of hazardous materials through tunnels, over bridges or other roadways. Always check before you start.

Whenever placarded, avoid heavily populated areas, crowds, tunnels, narrow streets and alleys. Take other routes, even if inconvenient, unless there is no other way. Never drive a placarded vehicle near open fires unless you can safely pass without stopping.
