New Jersey CDL: Hazardous Materials Practice Test

Not quite. The answer is Reflective triangles

Ideally, you should not risk exposing any type of hazardous material to flame, but especially Division 1.1, 1.2, or 1.3 (explosives), Division 2.1 (flammable gases), or Division 3 (flammable liquids). These can be so volatile that they should not be exposed to any heat source, not even a cargo heater. Set out warning triangles as explained in the section "Communicating Your Presence" in the New Jersey Commercial Driver License Manual.

Not quite. The answer is To certify that it has prepared the shipment in accordance with regulations

The shipping paper must include the shipper's certification signed by the shipper. It states that the shipper prepared the shipment according to the relevant regulations.

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 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.

Not quite. The answer is Turn it off before unhooking the hoses.

Keeping your engine on while you pump a load of compressed gas adds extra risk. As soon as the delivery is completed, turn off the engine before you unhook any hoses.

Not quite. The answer is All of the above

According to federal regulations, the shipper must provide emergency response information for the hazardous material being shipped. Emergency response information must include many things, including the technical name of the hazardous material and a description of it; emergency contacts to notify; methods for dealing with fires; methods for dealing with spills or leaks, if there is no fire; and first-aid procedures for treating exposures to the hazmat.

Not quite. The answer is by water.

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

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 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.

Not quite. The answer is Flammable Gas and Non-Flammable Gas

Flammable gases and non-flammable gases are in Placard Table 2. The rules for placarding Placard Table 2 materials are as follows: You must use placards if you'll be carrying a total of at least 1,001 pounds of these materials. If you are carrying several different materials, you normally use the placards for each individual material. Alternatively, you may use only the DANGEROUS placard, but only if you haven't loaded at least 2,205 pounds of any individual material at any one place. (In that case, you must use the placard for that material.)

Not quite. The answer is All of the above

Turn your engine off before loading or unloading any explosives. Then check the cargo space for the following: (1) There must be no sharp points that could damage the cargo. Look for bolts, screws, nails, broken side panels, and broken floorboards. (2) Disable any cargo heaters. (3) Make sure the floor lining is tight and made of either nonmetallic materials or non-ferrous metals.

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

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 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 On the shipping papers and on the packages

The two main places where you must keep the hazardous material identification numbers are on your shipping papers and on the packages, because these are the places that emergency personnel have been trained to check immediately.

Not quite. The answer is Only when it is a non-placarded material

You must have a hazardous materials endorsement on your CDL to drive a vehicle that is placarded for hazardous materials. However, not all packages of hazardous materials require placarding your vehicle. For example, relatively small quantities of consumer-grade chemicals such as drain openers and bleaches may be exempt. Federal regulation 49 CFR 172.500 exempts certain amounts and types of hazardous materials from placarding, but states may impose more stringent requirements. Check with the New Jersey Department of Transportation.

Not quite. The answer is three

Federal, state, and county regulations on the handling of hazardous materials can change at any time, and HazMat workers need to keep up with those changes. Federal regulation 49 CFR 172.704 requires every HazMat employee to be retrained every three years. This includes training in his or her employer's security plan. If the employer changes the security plan, it must train the employee about the changes within 90 days.

Not quite. The answer is Toxic Gases

Your CDL Handbook includes Placard Tables 1 and 2. Division 2.3 (Toxic Gases) is in Placard Table 1. Any amount of hazardous materials listed in Placard Table 1 must be placarded. Class 3 (Flammable Liquids) and Class 8 (Corrosives) are in Placard Table 2. Except for bulk packaging, the materials in Placard Table 2 must be placarded only if the total amount transported is 1,001 pounds or more, including the packages.

Not quite. The answer is The driver

At any time, states or counties can impose new rules on the permits you must have or new restrictions on the routes you may take. As the driver, you must keep up with these changes and work with the carrier to obtain any needed permits.

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).
