Delaware CDL: Hazardous Materials Practice Test

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],

Source: 49 CFR § 397.101

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 Classes 1, 2.1, and 3

The three hazard classes that must be kept in a trailer without automatic heating and cooling are explosives (1), flammable gases (2.1), and flammable liquids (3), because these materials are particularly volatile.

Not quite. The answer is cargo heaters have been disabled.

Ideally, you should not risk exposing any type of hazardous material to flame, but especially Division 1.1, 1.2, or 1.3 (explosives), Division 2.1 (flammable gases), or Division 3 (flammable liquids). These can be so volatile that they should not be exposed to any heat source, not even a cargo heater.

Not quite. The answer is must be signed by each carrier transporting the shipment.

A hazardous waste manifest acts as a record of everyone who has been involved in its shipment. Each copy must have all needed signatures and dates, including those of the person to whom you delivered the waste.

Not quite. The answer is Division 1.1, 1.2, or 1.3

If you are carrying Division 1.1, 1.2, or 1.3 materials (explosives), you must not park within five feet of the traveled roadway. If you can't get that far away, call emergency services.

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 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.

Source: 49 CFR 392.10

Not quite. The answer is a placarded cargo tank.

Division 1.1 or 1.2 materials (explosives) must not be transported in a combination vehicle if there is a placarded cargo tank in the combination. (The placarded cargo tank might hold flammable gases or liquids, for example.)

Not quite. The answer is make it easy to identify.

The regulations for packages of hazardous materials require shippers to make it easy for drivers, destination personnel, and emergency personnel to identify the contents quickly and easily.

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 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 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 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 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 10 B:C

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).

Not quite. The answer is The proper shipping name is appropriate for describing materials for domestic transportation, but may not be proper for international transportation.

Column 1 tells which shipping mode(s) the entry affects and other information concerning the shipping description. Six different symbols may appear in Column 1 of the table. (D) Means the proper shipping name is appropriate for describing materials for domestic transportation, but may not be proper for international transportation.

Not quite. The answer is Reflective triangles

Ideally, you should not risk exposing any type of hazardous material to flame, but especially Division 1.1, 1.2, or 1.3 (explosives), Division 2.1 (flammable gases), or Division 3 (flammable liquids). These can be so volatile that they should not be exposed to any heat source, not even a cargo heater. Set out warning triangles as explained in the section "Communicating Your Presence" in the State of Delaware Commercial Driver License Manual.

Not quite. The answer is the shipment is regulated by hazardous materials regulations.

On a shipping paper that lists both hazardous and nonhazardous materials, the hazardous materials must stand out for the reader. There are three ways to do this: List the hazardous materials first; highlight them in a contrasting color; or place an "X" or an "RQ" before their names. ("RQ" means that the hazardous material is being shipped in a reportable quantity.)

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.
