Mississippi CDL: Hazardous Materials Practice Test

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 3

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. Class 3 hazardous materials include flammable liquids and combustible liquids. Acetone, gasoline, and methanol are examples.

Not quite. The answer is is subject to the federal Hazardous Materials Regulations when it's transported by air.

The letter “A” in column 1 of the Hazardous Materials Table (HMT) denotes a material that is subject to the federal Hazardous Materials Regulations (49 CFR §§ 171–180) only when it's offered or intended for transportation by air, unless the material is a hazardous substance or a hazardous waste. A "hazardous substance" is a hazardous material that appears in Appendix A (List of Hazardous Substances and Reportable Quantities) of the HMT and is being shipped in an amount that exceeds its reportable quantity (RQ).

Not quite. The answer is The material is subject to the HMR only when offered or intended for transport by air unless it is a hazardous substance or hazardous waste.

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. (A) Means the hazardous material described in Column 2 is subject to the HMR only when offered or intended for transport by air unless it is a hazardous substance or hazardous waste.

Not quite. The answer is tabbing them.

You should clearly distinguish hazardous materials shipping papers from other materials' shipping papers by tabbing them or keeping them on top of the stack of papers.

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 300

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 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 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 diamond-shaped

The shipper must affix appropriate US DOT-compliant HazMat labels to the packages and supply the driver with the appropriate placards to attach to the vehicle. Both the labels and the placards are diamond shaped. [49 CFR 172.400],

Not quite. The answer is between 15 and 50 feet from

If your vehicle is placarded, you must stop between 15 and 50 feet from the nearest rail at a railroad crossing. After you have done so, proceed only when you are sure that no train is approaching and you can clear the tracks without stopping. Do not shift gears while crossing the tracks.

Not quite. The answer is both of the above.

Hazardous materials placards must be at least 9.84 inches (250 mm) square, square on point, in a diamond shape. ("Square on point" means a square that has been rotated 45 degrees so it is balanced on one corner, forming a diamond shape.) Each placard must have a solid line inner border approximately 12.5 mm inside and parallel to the edge.

Not quite. The answer is The written 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. In that case, you should create and follow your own route plan.

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 Inform someone and do not load the battery acid.

Silver cyanide and battery acid are on the list of materials that cannot travel together for safety reasons. (See the "Do Not Load" table in section 9.4 of the Mississippi Professional Driver's Manual.) Silver cyanide is a Division 6.1 material (poison). It cannot be loaded with acids because their mixture can release hydrocyanic acid, which is extremely poisonous.

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 20 feet long.

An ISO standard portable tank is a metal tank enclosed in a steel frame. The frame is 19.8556 feet (6.05 meters) long, 7.874 feet (2.40 meters) wide, and either 7.874 feet (2.40 meters) high or 8.374 feet (2.55 meters) high.

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 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 you have placed the explosives at least 200 feet away from the vehicles and occupied buildings.

If your vehicle is carrying explosives and collides with another vehicle, warn others of the danger. Keep bystanders away. Do not allow smoking or open fire near the vehicle. If there is a fire, warn everyone of the danger of explosion. Remove all the explosives before separating the two vehicles. Place the explosives at least 200 feet from the vehicles and any occupied buildings.
