Idaho CDL: Hazardous Materials Practice Test

Not quite. The answer is Within the United States and to and from Canada

A hazardous material identification number that starts with the letters "NA" is intended for shipment to, from, or through the United States or Canada (not Mexico). For shipment to, from, or through any other countries, the identification number must start with the letters "UN."

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 on the property of the shipper, carrier, or receiver.

Someone else can watch your vehicle only if you are on the shipper's, carrier's, or consignee's property, because those are the people who know the dangers and how to deal with them.

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 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 explosives C, flammable solids, or oxidizers.

Corrosive liquids can give off dangerous hydrogen gas if they come into contact with metal containers. Some corrosive liquids are themselves flammable. Don't load corrosive liquids next to or above anything that can cause or worsen a fire or explosion. Section 9.4 contains a complete list of hazardous materials that you should NOT load together with corrosive liquids.

Not quite. The answer is Name in italics

A hazardous material's proper shipping name should be displayed strictly in Roman print (no italics). Acceptable markings would include the appropriate descriptive name from the subchapter in your manual as well as UN marks, instructions, weight, ID number, specification, cautions, or some combination of these.

Not quite. The answer is Do both of the above.

If there is an emergency involving the hazardous materials that you're transporting, follow all instructions that your employer gave you. Keep bystanders away, preferably upwind, while warning them of the danger. Try to keep open flames away and don't let anyone smoke near the hazardous materials. Take a copy of your shipping papers with you to provide to first responders who arrive at the scene.

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 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 carrier

The carrier accepts responsibility for transporting the shipment. Before transport, the carrier must check that the shipper has correctly labeled and packaged the hazardous materials. The carrier should refuse to accept any package that is incorrectly labeled or packaged.

Not quite. The answer is MC-306 (DOT-406)

MC-306 (DOT-406) cargo tanks carry liquids under very low or no pressure (maximum allowable pressure of 3 psi for MC-306 and 4 psi for DOT-406). The cargo tank has an oval or elliptical cross section and is usually compartmented. These tanks are commonly used to carry gasoline, diesel fuel or fuel oil, and other flammable liquids.

Not quite. The answer is can safely pass the fire without stopping.

Never risk exposing any kind of hazardous material to fire. If your vehicle is placarded, don't drive near any open fire unless you are sure that you can drive right past it without stopping.

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 read the shipping papers and package labels to identify the materials.

If you discover a hazardous materials cargo leak, use the shipping papers, the package labels, or the package locations to help you identify which materials are leaking. Do not touch any leaking material; you can injure yourself by touching hazardous materials. Do not use your sense of smell to identify the material; inhaling toxic gases can be dangerous.

Not quite. The answer is $50,000

If there is an incident involving hazardous materials, you or your employer must call the National Response Center if any of the following have occurred: death or injury requiring hospitalization; more than $50,000 in estimated property damage; evacuation of the general public for more than one hour; the closure of a major road for more than one hour; damage to or spillage of radioactive substances; damage to or spillage of infectious agents; or any other incident that the carrier believes is dangerous enough to be reported.

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 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 Class 8

Your CDL Handbook includes Placard Tables 1 and 2. Division 2.3 (Toxic Gases) and Division 4.3 (Dangerous when Wet) are in Placard Table 1. Any amount of hazardous materials listed in Placard Table 1 must be placarded. Class 8 (Corrosives) is in Placard Table 2. Except for bulk packaging, the materials in Placard Table 2 must be placarded only if the total amount transported is 1,001 pounds or more, including the package.

Not quite. The answer is both of the above.

The shipping papers must describe all the materials and certify that the shipper has packaged them properly. The shipping papers must have page numbers so that the reader can tell whether any pages are missing.
