Nevada CDL: Hazardous Materials Practice Test

Not quite. The answer is contain the hazardous materials.

Among other things, the Hazardous Materials Regulations tell shippers how to package the materials safely and tell drivers how to load, transport, and unload the materials. These rules are called "containment rules."

Not quite. The answer is Medicines, food flavorings

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. However, some materials, such as medicines and food flavorings, are regulated but present only a limited hazard. Hence, they may not belong in any of the nine hazard classes. Note: Despite what your state CDL manual may claim, anthrax is caused by a bacterium, not a virus.

Not quite. The answer is The shipper

The shipping paper describes the hazardous material and its quantity, among other things. The shipper must fill out the shipping paper because the shipper packages the material. Only the shipper knows exactly what's inside the package. Except in an emergency, no one else should open the package to see what's inside until the package is delivered to the receiver.

Not quite. The answer is Close all manholes and valves. Be sure they are free of leaks.

Before you start to drive a vehicle with a cargo tank containing hazardous materials, make sure that the manholes and valves are closed and leak-free. It is illegal to move a cargo tank containing any amount of hazardous materials for any distance if any valves or covers are open.

Not quite. The answer is Yes, but only if the nitric acid is not loaded above any other materials.

Nitric acid is a liquid in Class 8 (Corrosives). Nitric acid is also a strong oxidizing agent. It can react with many other chemicals and start fires. Hence, as a safeguard against leaks or spills, nitric acid should not be loaded above any other product. There are additional restrictions on which classes of hazardous materials may be loaded in the same vehicle with corrosive liquids. See your CDL Handbook for details.

Not quite. The answer is eight

The Hazardous Materials Table lists every type of material (over 3,000 so far) that the US Department of Transportation has designated as a hazardous material for the purpose of transportation. This table is a reference for shippers and carriers. There are eight columns in the Hazardous Materials Table that deal with road transportation, describing the name of the material, its hazard class, its identification number, and so on. Consult the Nevada Commercial Driver License Manual for details.

Not quite. The answer is If you're driving a placarded vehicle or a bus transporting passengers

According to federal regulations, you must stop between 15 and 50 feet of every railroad crossing if any of the following is true: (1) You're driving a bus that is carrying passengers. (2) Your vehicle is placarded for transporting hazardous materials. (3) Your vehicle has cargo tanks for hazardous materials (whether loaded or empty). (4) You're carrying any amount of chlorine.

Not quite. The answer is On the driver's seat whenever you are out of the vehicle

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 on the driver's seat, within easy reach in case of an emergency.

Not quite. The answer is On the shipping papers and on the packages

The two main places where you must keep the hazardous material identification numbers are on your shipping papers and on the packages, because these are the places that emergency personnel have been trained to check immediately.

Not quite. The answer is UN 1090, Acetone, 3

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. (The answer choices for this question do not include the packing group.)

Not quite. The answer is 3 years; 2 years

When shipping hazardous materials, the shipper must keep a copy of the shipping papers for three years for hazardous waste, or for two years for other hazardous materials.

Not quite. The answer is Corrosive

Most batteries in motor vehicles are lead-acid batteries. These contain a solution of sulfuric acid and water. Sulfuric acid is corrosive. Concentrated sulfuric acid can burn the skin.

Not quite. The answer is Non-ferrous metal

Explosives should not be near anything that could emit sparks. The floor liner for transporting Division 1.1 or 1.2 materials must be made of nonmetallic materials or non-ferrous metals. Stainless steel and carbon steel are ferrous metals.

Not quite. The answer is 9

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. However, some materials, such as medicines and food flavorings, are regulated but present only a limited hazard. Hence, they may not belong in any of the nine hazard classes. Note: Despite what your official state CDL handbook may claim, anthrax is caused by a bacterium, not a virus.

Not quite. The answer is The material is subject to the HMR only when offered or intended for transport by air unless it is a hazardous substance or hazardous waste.

Column 1 tells which shipping mode(s) the entry affects and other information concerning the shipping description. Six different symbols may appear in Column 1 of the table. (A) Means the hazardous material described in Column 2 is subject to the HMR only when offered or intended for transport by air unless it is a hazardous substance or hazardous waste.

Not quite. The answer is bulk packaging permanently attached to your vehicle.

Cargo tanks are tanks that are permanently attached to a commercial vehicle. There are many different styles for transporting a variety of different materials.

Not quite. The answer is Send someone for help with all the necessary information.

Cleaning up a spill, a huge contamination in particular, is very expensive. Therefore, if you notice a leak, stop as soon as you possibly can and get off the road. Stay with your vehicle because of liability and safety issues and send someone else for help. You will need to send a large amount of vital information including your location, your direction of travel, the hazard class and ID numbers, your carrier's location, and the cargo's destination. Make sure you write it all down for the person seeking help.

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 Have a qualified person keep an eye on it.

If you must briefly park a placarded vehicle within 5 feet of the roadway because your work requires it, get someone else to watch the vehicle. That person must (a) be awake inside the vehicle (but not in the sleeper berth) or within 100 feet of the vehicle, in clear view of it; (b) be aware of the hazards posed by the materials being transported; (c) know what to do in case of an emergency; and (d) be able to move the vehicle if needed.

Not quite. The answer is warn others of the fire hazard.

Class 4 materials (Flammable Solids) can react with heat, water, or air, and start fires. Class 5 materials (Oxidizers) can react with many other substances and also start fires. If any of these materials are spilled, warn others of the fire hazard. Do not open smoldering packages of flammable solids. Remove them from the vehicle if you can safely do so. Also, remove unbroken packages if it will decrease the fire hazard.
