Arizona CDL: Hazardous Materials Practice Test

Not quite. The answer is No. The regulations may change.

The official state CDL manual contains all the information you need to know to pass the HazMat endorsement knowledge test. However, times change. Government and industry regulations for dealing with hazardous materials can change over time. Even after you obtain your HazMat endorsement, you'll need to keep up with those changes. (For example, in 2001, the PATRIOT Act became law, requiring HazMat drivers to be fingerprinted and undergo an extensive criminal background check.) Government regulations require training of all drivers involved in transporting hazardous materials. Your employer or a designated representative is required to provide you this training. You can also obtain and study a copy of Title 49 (transportation) of the Code of Federal Regulations (CFR). Also study your state's regulations.

Not quite. The answer is Dynamite, fireworks

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. Class 1 hazardous materials are explosives, including dynamite, flares, display fireworks, ammunition, blasting agents, and explosive devices.

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 flammable materials.

You should not risk smoking in close proximity to any class of hazardous material. However, there are specific rules for the following classes: No smoking within 25 feet of classes 3 and 2.1 (flammable materials and gases). No smoking or holding a lighted smoking object such as a cigar or pipe within 25 feet of classes 1, 3, 4, or 4.2 (explosives, flammable liquids or solids, or spontaneously combustible materials).

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 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 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 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 Arizona Commercial Driver License Manual.

Not quite. The answer is At the start of each trip and every time you stop

If you have a placarded trailer with dual tires, you should check the tires at the start of each trip and each time that you stop for any reason, whether to rest or to refuel. Use a tire pressure gauge to get an accurate reading.

Not quite. The answer is the entry is for a hazardous material.

There are a few ways to highlight a hazardous material on the shipping papers. One way is to enter an "X" in the shipping paper's HM column.

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 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 the shipper.

The shipper packs the hazardous materials for transport. The shipper must determine the correct identification number and record it on the packages and the shipping papers. (In the event of an accident, first responders are trained to look first at the packages and the shipping papers for the identification number.)

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 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 3

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. Class 3 hazardous materials include flammable liquids and combustible liquids. Acetone, gasoline, and methanol are examples.

Not quite. The answer is All of the above

Under federal regulations, you must communicate with the carrier at the beginning of your tour of duty, at each pickup, at each delivery, and at the end of your tour of duty.

Source: 49 CFR 385.415

Not quite. The answer is a place that has been approved for parking unattended vehicles carrying explosives.

The term "safe haven" refers to a place created by local authorities where you can safely leave your truck unattended by you while it holds explosive materials. While the rules for managing safe havens may vary by jurisdiction, the safe haven may be secured by warning signs and gates and patrolled by watch personnel who are trained in how to handle the dangers of hazardous materials. This solves a trucking dilemma that has often led drivers to make risky decisions, such as driving through the night so that they could stay with their loads.

Not quite. The answer is Ammonium nitrate

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. Class 5 hazardous materials include oxidizers (5.1), such as ammonium nitrate (fertilizer); and organic peroxides (5.2), such as methyl ethyl ketone peroxide (MEKP).

Not quite. The answer is at the nozzle, controlling the fuel flow.

Under federal regulation 49 CFR 397.15, whenever a motor vehicle carrying hazardous materials is being refueled, its engine must be turned off and someone must be at the nozzle, controlling fuel flow.
