Tennessee CDL: Hazardous Materials Practice Test

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 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 9

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 official state CDL handbook may claim, anthrax is caused by a bacterium, not a virus.

Not quite. The answer is 3 years; 2 years

When shipping hazardous materials, the shipper must keep a copy of the shipping papers for three years for hazardous waste, or for two years for other hazardous materials.

Not quite. The answer is Only if regulations specifically authorize the shipper to do it

The shipper may not abbreviate the hazardous material identification number, hazard class, or shipping name of a hazardous material unless the regulations specifically authorize it. Abbrevations might make it harder to identify the material correctly, which could be dangerous.

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 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 display POISON placards in addition to any other required placards.

If the words "INHALATION HAZARD" appear on the shipping paper or package, your vehicle must display the POISON INHALATION HAZARD or POISON GAS placards, as appropriate. These placards must be used in addition to any other placards that may be required by the material's hazard class or division.

Not quite. The answer is up to 50 feet from the nearest rail.

You must stop before a railroad crossing if your vehicle (a) is placarded; (b) carries any amount of chlorine; or (c) is towing a cargo tank for transporting hazardous materials, even if the tank is empty. You may stop between 15 and 50 feet from the nearest rail.

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.

Not quite. The answer is The shipper

The federal Hazardous Materials Regulations require shippers to provide adequate warning of the dangers associated with the hazardous materials. The regulations require shippers to put hazard warning labels on packages and provide proper shipping papers, emergency response information, and placards.

Not quite. The answer is To certify that it has prepared the shipment in accordance with regulations

The shipping paper must include the shipper's certification signed by the shipper. It states that the shipper prepared the shipment according to the relevant regulations.

Not quite. The answer is The shipper, all carriers, and the receiver

The Hazardous Waste Manifest must be signed by every agency involved in the transportation of the hazardous waste: the shipper, every carrier who transports it, and the receiver. After you deliver the shipment, keep your copy of the manifest.

Not quite. The answer is Send someone for help with all the necessary information.

Cleaning up a spill, a huge contamination in particular, is very expensive. Therefore, if you notice a leak, stop as soon as you possibly can and get off the road. Stay with your vehicle because of liability and safety issues and send someone else for help. You will need to send a large amount of vital information including your location, your direction of travel, the hazard class and ID numbers, your carrier's location, and the cargo's destination. Make sure you write it all down for the person seeking help.

Not quite. The answer is 5 feet

You may park a placarded vehicle (unless it's carrying explosives) within 5 feet of the traveled part of the road, but only if your work requires it. Do so only briefly. Corrosives are in Placard Table 2. Because you are transporting 1,001 pounds or more, your vehicle must be placarded.

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 look at the shipping papers.

If you need to know whether a shipment contains hazardous materials, just check the shipping papers, which should have hazardous materials clearly marked. (In the event of an accident, first responders will also check the shipping papers to find out what materials they're dealing with.)

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 have a written route plan and follow that route plan.

To transport explosives, you must usually follow a route plan prepared by the carrier. One exception is if you pick up the explosives at a location other than your employer's terminal. In that case, you should create and follow your own route plan.

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.
