Kentucky CDL: Hazardous Materials Practice Test

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 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 emergency response information.

The shipping papers must describe the hazardous materials (including the hazardous material identification numbers) and provide information on what to do and whom to contact in case of an emergency.

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 keep all people far away and upwind of the accident.

If you have an accident while carrying hazardous materials, you must follow your employer's instructions. However, keep bystanders well away and upwind of the accident for their own safety.

Not quite. The answer is If you're driving a placarded vehicle or a bus transporting passengers

According to federal regulations, you must stop between 15 and 50 feet of every railroad crossing if any of the following is true: (1) You're driving a bus that is carrying passengers. (2) Your vehicle is placarded for transporting hazardous materials. (3) Your vehicle has cargo tanks for hazardous materials (whether loaded or empty). (4) You're carrying any amount of chlorine.

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 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 four

You placard your vehicle to warn everyone around you that you are transporting hazardous materials. Therefore, you must have placards on all four sides of your vehicle.

Not quite. The answer is 25 feet of the vehicle.

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, 4.1, 4.2, or 5 (explosives, oxidizers, flammable liquids or solids, or spontaneously combustible materials).

Not quite. The answer is Non-ferrous metal

Explosives should not be near anything that could emit sparks. The floor liner for moving Division 1.1 or 1.2 materials must be either nonmetallic materials or non-ferrous metals. Stainless steel and carbon steel are ferrous metals.

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 Both of the above

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. Class 6 includes poisonous materials (6.1) and infectious substances (6.2).

Not quite. The answer is UN 1090, Acetone, 3

The basic description of hazardous materials includes the identification number, the proper shipping name, the hazard class or division, and the packing group, if any, in that order. The packing group is a grouping by the degree of danger as shown for that hazardous material in the Hazardous Materials Table. Packing Group I indicates great danger; Packing Group II, medium danger; and Packing Group III, minor danger. (The answer choices for this question do not include the packing group.)

Source: 49 CFR §§ 172.101 and 172.202

Not quite. The answer is placard your vehicle.

To obtain a hazardous materials endorsement, you must meet several requirements, including passing a specialized knowledge test on the transportation of hazardous materials. To pass the test, you must know the various hazard classes of hazardous materials, how to load packages of hazardous materials onto your vehicle safely, how to placard your vehicle, and how to transport those packages safely.

Not quite. The answer is Class 7 (radioactive materials)

Class 7 (radioactive materials) must be controlled by a transport index that tells each transport company and truck driver how much they can carry. The radiation given off by radioactive materials can contaminate the rest of the load.

Not quite. The answer is It provides technical information about the physical properties of hazardous materials.

The Chemical Transportation Emergency Center (CHEMTREC) offers technical assistance in the event of an incident involving hazardous materials. CHEMTREC has a 24-hour toll-free phone number that you can call. CHEMTREC was created to provide emergency personnel with technical information about the physical properties of hazardous materials. The National Response Center and CHEMTREC are in close communication. If you call either one, they will tell the other about the problem when appropriate.

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 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 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.
