Wyoming CDL: Hazardous Materials Practice Test

Not quite. The answer is at all times.

On the shipping papers, the basic description of a hazardous material includes (a) the total quantity and unit of measure, and (b) the number and type of packages.

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 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 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 by air.

The letter 'A' means the hazardous material described in Column 2 is subject to the Hazardous Materials Regulations only when offered or intended for transportation by air, unless it is a hazardous substance or hazardous waste.

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 Placards for both poisons and flammable materials

There are two placard tables, Table 1 and Table 2. Table 1 materials must be placarded whenever any amount is transported. Table 2 materials must be placarded whenever at least 1,001 pounds is transported. Therefore, when you transport a small amount of poison and 1,001 pounds or more of flammable materials, you need placards for both poisons and flammable materials.

Not quite. The answer is 100 mm

The hazardous material identification numbers must be displayed on portable tanks, cargo tanks, and other bulk packaging. The regulations require black 100 mm (3.9 inch) numbers on orange panels, placards, or a white, diamond-shaped background if no placards are required.

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 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 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 The identification number

The hazardous material identification number is a four-digit code used by first responders to identify the material, should an accident occur. The identification number must appear first on the shipping paper as part of the shipping description.

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 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],

Not quite. The answer is does all of the above.

The Emergency Response Guidebook (ERG) was created by the US Department of Transportation and is used by emergency personnel such as firefighters and paramedics to respond to trucking emergencies. The guidebook is indexed by hazardous material identification number, which is why it is very important that shipping papers be labeled correctly.

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 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 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 The name of a hazardous material used in scientific journals and texts, recognized as its chemical or microbiological name

The technical name is one used by scientists, which appears in journals, articles, and technical handbooks. It provides a standard terminology for dangerous substances, instead of slang terms that can vary (to dangerous effect) from region to region.

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.
