Montana CDL: Hazardous Materials Practice Test

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 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. (Good luck!) Place the explosives at least 200 feet from the vehicles and any occupied buildings.

Not quite. The answer is Because while being transported, they pose a risk to health, property, or safety

The government regulates the transportation of hazardous materials because by definition, they are potentially dangerous to health, property, public safety, or the environment. Examples include explosives, flammable liquids and gases, poisons, and radioactive materials.

Not quite. The answer is to communicate the risk.

The hazardous materials regulations are designed to help ensure the safety of shippers, carriers, drivers, and the general public. One way they do this is by requiring that packages of hazardous materials and the vehicles that transport them be clearly marked and accompanied by appropriate shipping papers. This lets emergency personnel and the public know the risks involved.

Not quite. The answer is a copy of FMCSR Part 397.

Each carrier must give drivers who transport explosives a copy of 49 CFR 397, "Transportation of Hazardous Materials; Driving and Parking Rules." It contains regulations regarding the routing of hazardous materials, including considerations when choosing a suitable route.

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 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 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 It provides technical information about the physical properties of hazardous materials.

The Chemical Transportation Emergency Center (CHEMTREC) offers technical assistance in the event of an incident involving hazardous materials. CHEMTREC has a 24-hour toll-free phone number that you can call. CHEMTREC was created to provide emergency personnel with technical information about the physical properties of hazardous materials. The National Response Center and CHEMTREC are in close communication. If you call either one, they will tell the other about the problem when appropriate.

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 $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 both the hazard class placard and the POISON INHALATION HAZARD or POISON GAS placards.

If the words INHALATION HAZARD appear on the shipping paper or package, the rules require display of the POISON INHALATION HAZARD or POISON GAS placards, as appropriate. These placards must be used in addition to other placards, which may be required by the product's hazard class. Always display the hazard class placard and the POISON INHALATION HAZARD placard, even for small amounts.

Not quite. The answer is 3 inches

Placards must be displayed so they can be easily read from the directions that they face. They must be kept clean, undamaged, unobscured by tarpaulins or other objects, and positioned at least three inches from any other markings.

Not quite. The answer is Both of the above

Chlorine gas is both toxic and oxidizing. It can react with flammable materials and start fires, which can spread corrosive or toxic gases. Federal regulation 49 CFR 177.840 requires every driver hauling chlorine to have available a gas mask rated for protection against chlorine gas, and a repair kit to repair leaks in fittings on the dome cover plate of the vehicle.

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 the shipment is regulated by hazardous materials regulations.

On a shipping paper that lists both hazardous and nonhazardous materials, the hazardous materials must stand out for the reader. There are three ways to do this: List the hazardous materials first; highlight them in a contrasting color; or place an "X" or an "RQ" before their names. ("RQ" means that the hazardous material is being shipped in a reportable quantity.)

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 placard your vehicle.

To obtain a hazardous materials endorsement, you must meet several requirements, including passing a specialized knowledge test on the transportation of hazardous materials. To pass the test, you must know the various hazard classes of hazardous materials, how to load packages of hazardous materials onto your vehicle safely, how to placard your vehicle, and how to transport those packages safely.

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 The driver

Once the hazardous material is on the road, the driver has control of and responsibility for transporting the hazardous materials in a timely manner and keeping the shipping papers where they need to be.
