Maine CDL: Hazardous Materials Practice Test

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 must be electrically non-conductive (hence its C rating).

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 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 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 loaded upright or lying down flat and braced.

If you do not have racks for the cylinders, you must load them so they can't be thrown about your vehicle. Load them so they'll brace each other, by positioning them upright or flat and braced.

Not quite. The answer is refuse the package.

The driver must refuse any leaking packages or shipments.

Not quite. The answer is Generic shipping name

The letter 'G' means the hazardous material described in Column 2 is a generic shipping name. A generic shipping name must be accompanied by one or more technical names in parentheses on the shipping paper. A technical name is the name of a specific chemical that makes the product hazardous.

Not quite. The answer is any of the above

Obviously, if there is a spill of a Class 3 material (flammable liquid) or a Class 4 material (flammable solid), you should take precautions against a fire hazard. But Class 5 materials (oxidizers) can react with some flammable substances in the area and also cause a fire. Finally, many Class 6 materials (poisons) are also flammable. Hence, it's wise to take fire precautions when dealing with Class 5 or Class 6 materials too. (Note: This topic is not usually found in the official state CDL handbook.)

Not quite. The answer is None of the above provides sufficient assurance.

Federal regulations define an "undeclared hazardous material" as a hazardous material that is subject to the communication requirements (labels, shipping papers, etc.) for hazardous materials, but which is shipped without any indication to the carrier that the package contains hazardous materials. Each year, about 1,500 transportation incidents occur when undeclared hazardous materials are shipped. Transportation workers have been injured when undeclared hazardous materials leaked from packages. It is the responsibility of the shipper to know whether the items being shipped contain hazardous materials and to comply with the hazardous materials regulations if required. There are substantial penalties for deliberately shipping hazardous materials without complying with the federal or state requirements for their shipment.

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 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 Division 6.1

Never transport Division 2.3 materials (poisonous gases) or Division 6.1 materials (poisonous materials) in containers with interconnections. Also, never load any package containing poisons in the driver's cab or sleeper or together with foods for human or animal consumption.

Not quite. The answer is The carrier

When placarded radioactive materials must be transported, it's the carrier's job to choose the safest route. After choosing the route, the carrier must tell the driver about the radioactive materials, and show the driver the route plan.

Not quite. The answer is Before starting the trip

Before you start your trip, become familiar with the route. Make sure that state and county laws and regulations allow you to use that route. If the route is densely populated, consider using an alternative route. Obtain any needed permits ahead of time.

Not quite. The answer is "Explosives" placards.

The Placard Tables (which you'll find in your official state CDL manual) describe which materials must be placarded and what the placards must say. Explosives are in Placard Table 1, so your vehicle must have placards that say "Explosives" followed by the division number (1.1, 1.2, or 1.3).

Not quite. The answer is three

Federal, state, and county regulations on the handling of hazardous materials can change at any time, and HazMat workers need to keep up with those changes. Federal regulation 49 CFR 172.704 requires every HazMat employee to be retrained every three years. This includes training in his or her employer's security plan. If the employer changes the security plan, it must train the employee about the changes within 90 days.

Not quite. The answer is Because while being transported, they pose a risk to health, property, or safety

The government regulates the transportation of hazardous materials because by definition, they are potentially dangerous to health, property, public safety, or the environment. Examples include explosives, flammable liquids and gases, poisons, and radioactive materials.

Not quite. The answer is The shipper

The shipping paper describes the hazardous material and its quantity, among other things. The shipper must fill out the shipping paper 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 All of the above

Non-bulk packaging has specific requirements to be used as a receptacle for solids, liquids, or gases. To qualify as non-bulk, it must satisfy the following: 450 L (119 gallons) or less for liquids, 400 kg (882 pounds) or less and 450 L (119 gallons) or less for solids, and 454 kg (1,000 pounds) or less for gases.

Not quite. The answer is Yellow III

A package of radioactive materials is not completely radiation proof. Some radiation can pass through the package. There are three different diamond-shaped "RADIOACTIVE" labels that can be affixed to a package of radioactive materials: White I, Yellow II, and Yellow III (in Roman numerals), depending on how much radiation is detectable at the surface of the package. Yellow III packages have the highest detectable radiation level at the package surface. (Note: This topic is not usually found in the official state CDL handbook.)
