North Carolina CDL: Hazardous Materials Practice Test

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 To communicate risk

Placards are signs posted on the outside of the vehicle to warn others about hazardous materials. These signs identify the hazard class of the cargo.

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.

Not quite. The answer is leave the doors closed.

If the cargo doors are hot, it's more likely that there's a fire inside. Opening the cargo doors will let more oxygen into the cargo area and feed the fire. Keeping the doors closed will deprive the fire of additional oxygen. Without additional oxygen, the fire may just smolder until firefighters can arrive.

Not quite. The answer is 300 feet

When driving with a load of Division 1.1, 1.2, or 1.3 hazardous materials, which are explosives, you must park at least 300 feet away from any bridge, tunnel, or structure. You must maintain the same distance from any gathering place or open fire.

Not quite. The answer is 30 days.

If a hazardous material is released, resulting in death, hospitalization, over $50,000 in property damage, or other major problems, the driver or carrier must phone the National Response Center immediately. The carrier must also submit a written report to the National Response Center within 30 days of the incident.

Not quite. The answer is do either of the above.

If a shipping paper includes both hazardous and non-hazardous materials, the hazardous materials must be clearly identifiable. The shipper can do this by listing hazardous materials first, highlighting them in a contrasting color, or marking them with an “X” in a column labeled “HM.” If a reportable quantity applies, the letters “RQ” may be used instead of “X.

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 up to 50 feet from the nearest rail.

You must stop before a railroad crossing if your vehicle (a) is placarded; (b) carries any amount of chlorine; or (c) is towing a cargo tank for transporting hazardous materials, even if the tank is empty. You may stop between 15 and 50 feet from the nearest rail.

Not quite. The answer is All of the above

The hazardous materials regulations (HMR) don't just apply to the movement of hazmat. These regulations also apply to those operations that are considered incidental to the movement of hazmat. Such operations include loading and unloading, blocking and bracing, and segregating hazmat from incompatible cargo. For bulk packaging transported by road, the HMR also apply to the transloading (transfer) of hazmat from one bulk package to another; and to the emptying of hazmat from the bulk package, upon delivery to the receiver.

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 Turn it off before unhooking the hoses.

Keeping your engine on while you pump a load of compressed gas adds extra risk. As soon as the delivery is completed, turn off the engine before you unhook any hoses.

Not quite. The answer is 300

When driving with a load of Division 1.1, 1.2, or 1.3 hazardous materials, which are explosives, you must park at least 300 feet away from any bridge, tunnel, or structure. You must maintain the same distance from any gathering place or open fire.

Not quite. The answer is Class 4

Division 4.3 materials are Dangerous When Wet. An example is potassium metal. Potassium reacts with water to produce hydrogen gas. The reaction is so strong that the hydrogen gas ignites. (This effect is sometimes demonstrated in school science classes.) Under federal regulations, all materials in Classes 4 and 5 that can become dangerous when wet must be kept dry during loading, transport, and unloading.

Not quite. The answer is PHMSA

If you must complete a Hazardous Materials Incident Report, you must submit it to the Pipeline and Hazardous Materials Safety Administration (PHMSA). It can be submitted by mail or electronically at the PHMSA website. At that website, search for "Incident Reporting". (Note: This topic is not usually found in the official state CDL handbook.)

Not quite. The answer is All of the above

Non-bulk packaging has specific requirements to be used as a receptacle for solids, liquids, or gases. To qualify as non-bulk, it must satisfy the following: 450 L (119 gallons) or less for liquids, 400 kg (882 pounds) or less and 450 L (119 gallons) or less for solids, and 454 kg (1,000 pounds) or less for gases.

Not quite. The answer is are not proper shipping names.

A hazardous material's proper shipping name should be displayed strictly in Roman print (no italics).

Not quite. The answer is poisons.

Federal regulation 49 CFR 184.680 stipulates that you cannot place Division 6.1 materials (poisons) in the same cargo space as foodstuffs intended for animal or human consumption. The risk of contaminating the foodstuffs is unacceptable. Also, federal regulation 49 CFR 177.848 stipulates that certain hazardous materials, such as poisons, cannot be placed in the same cargo space as other hazardous materials because of the risk of cross-contamination or a dangerous chemical reaction. Some of these rules can be found in the Do Not Load Table in the North Carolina Commercial Driver License Manual.

Not quite. The answer is never use hooks or other metal tools.

Explosives should never be exposed to electric sparks. Metal tools can generate or conduct electric sparks. Use nonmetallic tools.

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.
