Florida CDL: Hazardous Materials Practice Test

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 Florida CDL Handbook.) 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 Corrosive

Most batteries in motor vehicles are lead-acid batteries. These contain a solution of sulfuric acid and water. Sulfuric acid is corrosive. Concentrated sulfuric acid can burn the skin.

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 remove the tire and place it a safe distance from the vehicle.

An overheated tire is more prone to blowing out. Remove it and place it at a safe distance from the vehicle. Don't drive until you find out what caused the tire to overheat.

Not quite. The answer is bulk packaging permanently attached to your vehicle.

Cargo tanks are tanks that are permanently attached to a commercial vehicle. There are many different styles for transporting a variety of different materials.

Not quite. The answer is Ammonium nitrate

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. Class 5 hazardous materials include oxidizers (5.1), such as ammonium nitrate (fertilizer); and organic peroxides (5.2), such as methyl ethyl ketone peroxide (MEKP).

Not quite. The answer is 2 years.

Your carrier must keep a copy of the Hazardous Materials Incident Report for two years. Normally, it must be kept at the carrier's primary place of business. If it is not kept at the carrier’s primary place of business, then it must be made available within 24 hours of a request by the Department of Transportation (DOT). (Note: This topic is not usually found in the official state CDL handbook.)

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 4 psi.

One of the most common types of cargo tanks is the DOT-406, typically used for fuel delivery. A semi-truck with a DOT-406 mounted to the semitrailer is commonly called a "gasoline truck." DOT-406 tanks have a low maximum allowable working pressure (MAWP) of 4 psi.

Not quite. The answer is Hazardous Materials Regulations apply only if the material is shipped by water.

In the Hazardous Materials Table, the letter "W" in Column 1 means that the hazardous material described in Column 2 is subject to the Hazardous Materials Regulations only if the material is offered or intended for transportation by water, unless it is a hazardous substance, hazardous waste, or marine pollutant. The federal Hazardous Materials Regulations are in 49 CFR §§ 171–180.

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 Florida CDL Handbook for details.

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 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 one hour.

You or your employer must call the National Response Center if an incident involving hazardous materials has consequences such as someone being killed or seriously injured, major roads being closed for at least an hour, the general public being evacuated for at least an hour, more than $50,000 of property being damaged, etc. For a full list, see section 9.7.5 of the Florida CDL Handbook.

Not quite. The answer is the front, the rear, and both sides.

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 A

You may have seen the term "hazard zone" in the Hazardous Materials Table. A poisonous material's "hazard zone" (not to be confused with its "hazard class") is the degree of hazard that it poses, based on how toxic it is. The hazard zone is based on the minimum concentration of the material that will kill 50% of those who are exposed to it. Division 2.3 poisonous gases have four possible hazard zones, A, B, C, and D, in descending order of toxicity. Division 6.1 poisonous liquids have just two possible hazard zones, A and B, also in descending order of toxicity. For either poisonous gases or poisonous liquids, hazard zone A poses the greatest hazard. According to federal regulation 49 CFR 173.116, a poisonous gas in hazard zone A will kill 50% of those exposed to a concentration of just 200 parts per million. Your carrier must apply for a Hazardous Materials Safety Permit (HMSP) to haul poisonous materials in certain safety zones. For example, to haul more than 1 liter or 1.08 quarts of a material that is poisonous by inhalation and is in hazard zone A, your carrier must hold a Hazardous Materials Safety Permit.

Not quite. The answer is any amount

If you are carrying any amount of chlorine gas, you must stop at every railroad crossing and be extra cautious about proceeding across. A chlorine spill from a collision with a train could be quite dangerous. Chlorine gas is poisonous. (If you're transporting chlorine in cargo tanks, you must have a gas mask with you in the cab.) Chlorine is also a strong oxidizing agent. It can react with flammable materials and start fires. The resulting fires can spread corrosive or toxic gases.

Not quite. The answer is 2

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. Class 2 includes various gases: flammable gases (2.1), such as propane; non-flammable gases (2.2), such as helium; and toxic gases (2.3), such as compressed fluorine.

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 "X" in the shipping paper's HM column.

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.
