Colorado CDL: Hazardous Materials Practice Test

Not quite. The answer is To certify that it has prepared the shipment in accordance with regulations

The shipping paper must include the shipper's certification signed by the shipper. It states that the shipper prepared the shipment according to the relevant regulations.

Not quite. The answer is any of the above

Obviously, if there is a spill of a Class 3 material (flammable liquid) or a Class 4 material (flammable solid), you should take precautions against a fire hazard. But Class 5 materials (oxidizers) can react with some flammable substances in the area and also cause a fire. Finally, many Class 6 materials (poisons) are also flammable. Hence, it's wise to take fire precautions when dealing with Class 5 or Class 6 materials too. (Note: This topic is not usually found in the official state CDL handbook.)

Not quite. The answer is the carrier must report a significant spill of this material.

There are a few ways to highlight a hazardous material on the shipping papers. One way is to enter "RQ" (reportable quantity) in the HM column. Any spill of a hazardous material that is at least equal to the reportable quantity for such a material must be reported to the National Response Center.

Not quite. The answer is emergency response information.

The shipping papers must describe the hazardous materials (including the hazardous material identification numbers) and provide information on what to do and whom to contact in case of an emergency.

Not quite. The answer is must put the word "WASTE" before the proper shipping name of the material on the shipping paper.

A shipper of hazardous wastes must put the word "WASTE" before the proper shipping name of the material on the shipping paper (hazardous waste manifest). Federal regulations require shippers to put hazard warning labels on packages and provide proper shipping papers, emergency response information, and placards, regardless of whether the material being shipped is waste.

Not quite. The answer is on all bulk packaging and on the cargo tanks.

In addition to the two main locations for the hazardous material identification number, you must also display it on the cargo tanks and on all bulk packaging.

Not quite. The answer is three

Federal, state, and county regulations on the handling of hazardous materials can change at any time, and HazMat workers need to keep up with those changes. Federal regulation 49 CFR 172.704 requires every HazMat employee to be retrained every three years. This includes training in his or her employer's security plan. If the employer changes the security plan, it must train the employee about the changes within 90 days.

Not quite. The answer is All of the above

Turn your engine off before loading or unloading any explosives. Then check the cargo space for the following: (1) There must be no sharp points that could damage the cargo. Look for bolts, screws, nails, broken side panels, and broken floorboards. (2) Disable any cargo heaters. (3) Make sure the floor lining is tight and made of either nonmetallic materials or non-ferrous metals.

Not quite. The answer is in the pouch on the driver’s door.

Your shipping papers for hazardous materials must be visible and accessible to emergency personnel at all times, including when you are out of the vehicle. Therefore, whenever you are away from your vehicle, they must be left in a pouch on the driver's side door or on the driver's seat, within easy reach in case of an emergency.

Not quite. The answer is 15 to 50

If your vehicle is placarded, you must stop between 15 and 50 feet from the nearest rail at a railroad crossing. After you have done so, proceed once you are sure that no train is approaching, and do not shift while you are on the tracks.

Not quite. The answer is Inform someone and do not load the battery acid.

Silver cyanide and battery acid are on the list of products that cannot travel together for safety reasons (see the "Do Not Load" table in the Handbook). Silver cyanide is a Division 6.1 material. It cannot be loaded with acids because their mixture can release such chemicals as hydrocyanic acid, which is extremely poisonous.

Not quite. The answer is Division 6.1

Never transport Division 2.3 materials (poisonous gases) or Division 6.1 materials (poisonous materials) in containers with interconnections. Also, never load any package containing poisons in the driver's cab or sleeper or together with foods for human or animal consumption.

Not quite. The answer is PHMSA

The Pipeline and Hazardous Materials Safety Administration (PHMSA) isn't just about pipeline transport. PHMSA develops and enforces regulations for the safe, reliable, and environmentally sound transportation of energy products by pipeline and of hazardous materials by land, sea, and air. PHMSA establishes national policies, sets and enforces standards, educates, and conducts research to prevent hazmat incidents. PHMSA is also the agency that publishes the Emergency Response Guidebook (ERG). (Note: This topic is not usually found in the official state CDL handbook.)

Not quite. The answer is Non-ferrous metal

The floor lining for moving materials from either categories 1.1 or 1.2 must be either nonmetallic materials or non-ferrous metals. Stainless steel and carbon steel are ferrous metals.

Not quite. The answer is The driver

At any time, states or counties can impose new rules on the permits you must have or new restrictions on the routes you may take. As the driver, you must keep up with these changes and work with the carrier to obtain any needed permits.

Not quite. The answer is 2

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. Class 2 includes various gases: flammable gases (2.1), such as propane; non-flammable gases (2.2), such as helium; and toxic gases (2.3), such as compressed fluorine.

Not quite. The answer is The identification number

The basic description of hazardous materials includes the identification number, the proper shipping name, the hazard class or division, and the packing group, if any, in that order. The packing group is a grouping by the degree of danger as shown for that hazardous material in the Hazardous Materials Table. Packing Group I indicates great danger; Packing Group II, medium danger; and Packing Group III, minor danger.

Not quite. The answer is B

Marine pollutants are chemicals that are toxic to marine life. Marine pollutants, including severe marine pollutants, are listed in Appendix B to the Hazardous Materials Table. Appendix A is the List of Hazardous Substances and Reportable Quantities. There is no Appendix C or Appendix D.

Not quite. The answer is Diamond

Hazardous materials placards must be readable from all four directions. They must be at least 9.84 inches (250 mm) square, square on point, in a diamond shape. ("Square on point" refers to a square that has been rotated 45 degrees so it is balanced on one corner, forming a diamond shape.)

Not quite. The answer is 5 feet

You may park a placarded vehicle (unless it's carrying explosives) within 5 feet of the traveled part of the road, but only if your work requires it. Do so only briefly. Corrosives are in Placard Table 2. Because you are transporting 1,001 pounds or more, your vehicle must be placarded.
