Utah CDL: Hazardous Materials Practice Test

Not quite. The answer is you will have to use placards.

The hazard classes listed in Placard Table 1 are particularly hazardous. These include mass explosives (1.1) and toxic gases (2.3). You must use placards to carry any amount of the hazard classes in Placard Table I.

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 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 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 within 25 feet.

Whenever you load or unload a cargo tank, there must be a qualified person no farther than 25 feet away who can observe the process and intervene if necessary. This person must know the hazards and what to do in case of an emergency. He or she must also be authorized to move the cargo tank and able to do so if necessary.

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.

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 C) the manufacturing date of the material.

You do not need to know when a product was manufactured or expires unless your company has an additional responsibility. You do need to know the amount of the hazardous material being shipped, its hazard class, and the total amount of all the hazardous materials of all classes that will be carried on your commercial vehicle during your trip.

Not quite. The answer is A

You may have seen the term "hazard zone" in the Hazardous Materials Table. A poisonous material's "hazard zone" (not to be confused with its "hazard class") is the degree of hazard that it poses, based on how toxic it is. The hazard zone is based on the minimum concentration of the material that will kill 50% of those who are exposed to it. Division 2.3 poisonous gases have four possible hazard zones, A, B, C, and D, in descending order of toxicity. Division 6.1 poisonous liquids have just two possible hazard zones, A and B, also in descending order of toxicity. For either poisonous gases or poisonous liquids, hazard zone A poses the greatest hazard. According to federal regulation 49 CFR 173.116, a poisonous gas in hazard zone A will kill 50% of those exposed to a concentration of just 200 parts per million. Your carrier must apply for a Hazardous Materials Safety Permit (HMSP) to haul poisonous materials in certain safety zones. For example, to haul more than 1 liter or 1.08 quarts of a material that is poisonous by inhalation and is in hazard zone A, your carrier must hold a Hazardous Materials Safety Permit.

Not quite. The answer is MC-331

MC-331 cargo tanks carry gases that are liquefied under relatively high pressure (maximum allowable pressure of 100–500 psi). The cargo tank has a circular cross section and rounded ends. These tanks are commonly used to carry such gases as propane and liquefied petroleum gas (LPG).

Not quite. The answer is Radioactive Materials

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. Class 7 materials are radioactive materials. These include radioactive metals, ionization smoke detectors that contain the isotope Americium 241, medical and scientific isotopes, and spent nuclear fuel.

Not quite. The answer is The driver

At any time, states or counties can impose new rules on the permits you must have or new restrictions on the routes you may take. As the driver, you must keep up with these changes and work with the carrier to obtain any needed permits.

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 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 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 The shipper

The shipping papers describe the hazardous material and its quantity, among other things. The shipper must fill out the shipping papers 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 any amount

If you are carrying any amount of chlorine gas, you must stop at every railroad crossing and be extra cautious about proceeding across. A chlorine spill from a collision with a train could be highly dangerous. Chlorine gas is poisonous. (If you're transporting chlorine in cargo tanks, you must have a gas mask with you in the cab.) Chlorine is also a strong oxidizing agent. It can react with flammable materials and start fires. The resulting fires can spread corrosive or toxic gases.

Not quite. The answer is Only during an emergency, to protect life or property

Normally, when your vehicle is carrying hazardous materials, you must attach the appropriate placards to the vehicle before you drive it. You are allowed to move an improperly placarded vehicle only during an emergency, to protect life or property.

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 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.
