New Mexico CDL: Hazardous Materials Practice Test

Not quite. The answer is you have placed the explosives at least 200 feet away from the vehicles and occupied buildings.

If your vehicle is carrying explosives and collides with another vehicle, warn others of the danger. Keep bystanders away. Do not allow smoking or open fire near the vehicle. If there is a fire, warn everyone of the danger of explosion. Remove all the explosives before separating the two vehicles. (Good luck!) Place the explosives at least 200 feet from the vehicles and any occupied buildings.

Not quite. The answer is have a written route plan and follow that route plan.

To transport explosives, you must usually follow a route plan prepared by the carrier. One exception is if you pick up the explosives at a location other than your employer's terminal. In that case, you should create and follow your own route plan.

Not quite. The answer is 119 gallons.

Appendix B to the Hazardous Materials Table is the List of Marine Pollutants. For road transportation, this list is only used for chemicals in a container with a capacity of 119 gallons or more without a placard or label as specified by the hazardous materials regulations.

Not quite. The answer is both the hazard class placard and the POISON INHALATION HAZARD or POISON GAS placards.

If the words INHALATION HAZARD appear on the shipping paper or package, the rules require display of the POISON INHALATION HAZARD or POISON GAS placards, as appropriate. These placards must be used in addition to other placards, which may be required by the product's hazard class. Always display the hazard class placard and the POISON INHALATION HAZARD placard, even for small amounts.

Not quite. The answer is Call emergency personnel if needed.

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. If an accidental release of hazardous materials results in death, hospitalization, over $50,000 in property damage, or other major problems, you or the carrier must phone the National Response Center immediately.

Not quite. The answer is any more than safety requires.

You don't want to leave a trail of hazardous materials behind you as you drive. The carrier will have to pay for the cleanup of any contaminated areas, which can be very expensive. Minimize the extent of the contamination. Move your vehicle only enough to ensure the safety of the general public. Then park your vehicle. Your vehicle and its cargo are still your responsibility, so stay with your vehicle and send someone else to get help.

Not quite. The answer is to communicate the risk posed by the hazardous materials.

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

Not quite. The answer is 4 psi.

One of the most common types of cargo tanks is the DOT-406, typically used for fuel delivery. A semi-truck with a DOT-406 mounted to the semitrailer is commonly called a "gasoline truck." DOT-406 tanks have a low maximum allowable working pressure (MAWP) of 4 psi.

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 a common carrier must never transport the material.

If a material is listed as "Forbidden" in column 3 of the Hazardous Materials Table, you must not transport any amount of that material. An example is silver fulminate (dry), an extremely sensitive explosive. (It's so sensitive that a sufficiently large quantity will explode under its own weight.)

Not quite. The answer is 1,001 pounds or more.

To transport hazardous materials listed in Placard Table 2, you must use placards only if you are transporting a total of 1,001 pounds or more. If you are transporting more than one hazardous material, find out the amount of each from its shipping paper.

Not quite. The answer is Any of the above

Under federal regulation 49 CFR 171.16, you must submit a Hazardous Materials Incident Report if an unintentional release of hazardous materials occurs. You must also submit a Hazardous Materials Incident Report if any of the following incidents occurs, even if hazmat is not released: (1) a reportable incident (death, injury, evacuation, etc.) occurs; (2) the lading retention system of a cargo tank containing hazmat is damaged; (3) undeclared hazmat is discovered; or (4) a fire, violent rupture, explosion, or dangerous evolution of heat occurs that might damage the packaging of the hazmat. Note: The "lading retention system" of a cargo tank consists of those items or pieces of equipment that provide containment of the hazmat.

Not quite. The answer is All of the above

The Hazardous Materials Regulations accomplish several things. They help ensure safe drivers and equipment. They communicate the risk of hazardous materials through the use of appropriate labels, placards, and shipping papers. Also, the regulations tell shippers how to package the materials safely, and they tell drivers how to load, transport, and unload the materials. These rules are called "containment rules."

Not quite. The answer is The shipper

The federal Hazardous Materials Regulations require shippers to provide adequate warning of the dangers associated with the hazardous materials. The regulations require shippers to put hazard warning labels on packages and provide proper shipping papers, emergency response information, and placards.

Not quite. The answer is how to package, load, transport, and unload hazardous materials safely.

Containment rules cover the entire process of transporting hazardous materials safely, from how to package them safely to how to unload them safely at the end of the trip.

Not quite. The answer is List of Hazardous Substances and Reportable Quantities.

There are three lists used to identify hazardous materials, all created by the US Department of Transportation: (1) the Hazardous Materials Table (49 CFR 172.101); (2) Appendix A to that section, known as the List of Hazardous Substances and Reportable Quantities; and (3) Appendix B to that section, known as the List of Marine Pollutants. Before transporting a hazardous material, you should check all three lists because some materials will be found on more than one list.

Not quite. The answer is 2 years.

Federal regulations normally require every HazMat employee to be retrained every three years. However, a driver who transports route-controlled radioactive materials must have received written training within the past two years, on the following topics: (1) the federal regulations governing the transportation of radioactive materials, (2) the properties and hazards of the radioactive materials that the driver is to transport, and (3) the procedures that the driver must follow in the event of an accident or other emergency. The driver must hold a certificate of training as evidence of this required training. [49 CFR § 172.704],

Not quite. The answer is Hazardous Materials Regulations apply only if the material is shipped by water.

In the Hazardous Materials Table, the letter "W" in Column 1 means that the hazardous material described in Column 2 is subject to the Hazardous Materials Regulations only if the material is offered or intended for transportation by water, unless it is a hazardous substance, hazardous waste, or marine pollutant. The federal Hazardous Materials Regulations are in 49 CFR §§ 171–180.

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 10

All placarded vehicles are required to have a fire extinguisher with a minimum UL rating of 10 B:C. That is, it must be able to extinguish a 10-square-foot class B fire (which includes almost all flammable liquids) and be electrically non-conductive (hence its C rating).
