Minnesota CDL: Hazardous Materials Practice Test

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 can safely pass the fire without stopping.

Never risk exposing any kind of hazardous material to fire. If your vehicle is placarded, don't drive near any open fire unless you are sure that you can drive right past it without stopping.

Not quite. The answer is $50,000

If there is an incident involving hazardous materials, you or your employer must call the National Response Center if any of the following have occurred: death or injury requiring hospitalization; more than $50,000 in estimated property damage; evacuation of the general public for more than one hour; the closure of a major road for more than one hour; damage to or spillage of radioactive substances; damage to or spillage of infectious agents; or any other incident that the carrier believes is dangerous enough to be reported.

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 leave the doors closed.

If the cargo doors are hot, it's more likely that there's a fire inside. Opening the cargo doors will let more oxygen into the cargo area and feed the fire. Keeping the doors closed will deprive the fire of additional oxygen. Without additional oxygen, the fire may just smolder until firefighters can arrive.

Not quite. The answer is Diamond

Hazardous materials placards must be readable from all four directions. They must be at least 9.84 inches (250 mm) square, square on point, in a diamond shape. ("Square on point" refers to a square that has been rotated 45 degrees so it is balanced on one corner, forming a diamond shape.)

Not quite. The answer is eight

The Hazardous Materials Table lists every type of material (over 3,000 so far) that the US Department of Transportation has designated as a hazardous material for the purpose of transportation. This table is a reference for shippers and carriers. There are eight columns in the Hazardous Materials Table that deal with road transportation, describing the name of the material, its hazard class, its identification number, and so on. Consult the Minnesota Commercial Driver's Manual for details.

Not quite. The answer is 25 feet of the vehicle.

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, 4.1, 4.2, or 5 (explosives, oxidizers, flammable liquids or solids, or spontaneously combustible materials).

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 explosives C, flammable solids, or oxidizers.

Corrosive liquids can give off dangerous hydrogen gas if they come into contact with metal containers. Some corrosive liquids are themselves flammable. Don't load corrosive liquids next to or above anything that can cause or worsen a fire or explosion. Section 9.4 contains a complete list of hazardous materials that you should NOT load together with corrosive liquids.

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 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 Minnesota Commercial 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 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 B

Marine pollutants are chemicals that are toxic to marine life. Marine pollutants, including severe marine pollutants, are listed in Appendix B to the Hazardous Materials Table. Appendix A is the List of Hazardous Substances and Reportable Quantities. There is no Appendix C or Appendix D.

Not quite. The answer is At least 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 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 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 C) the manufacturing date of the material.

You do not need to know when a product was manufactured or expires unless your company has an additional responsibility. You do need to know the amount of the hazardous material being shipped, its hazard class, and the total amount of all the hazardous materials of all classes that will be carried on your commercial vehicle during your trip.

Not quite. The answer is Column 4

Column 4 of the Hazardous Materials Table lists the hazardous material identification numbers. This number must be provided on the shipping papers, the packages, the cargo tanks, and other bulk packaging. In the event of an accident, first responders will use this information to identify the hazardous material and decide what to do.

Not quite. The answer is Class 4

Division 4.3 materials are Dangerous When Wet. An example is potassium metal. Potassium reacts with water to produce hydrogen gas. The reaction is so strong that the hydrogen gas ignites. (This effect is sometimes demonstrated in school science classes.) Under federal regulations, all materials in Classes 4 and 5 that can become dangerous when wet must be kept dry during loading, transport, and unloading.
