Hawaii CDL: Hazardous Materials Practice Test

Not quite. The answer is Within the United States and to and from Canada

A hazardous material identification number that starts with the letters "NA" is intended for shipment to, from, or through the United States or Canada (not Mexico). For shipment to, from, or through any other countries, the identification number must start with the letters "UN."

Not quite. The answer is indicates the degree of control needed during transportation.

A package of radioactive materials is not fully radiation proof. Some radiation can pass right through the package, possibly contaminating its immediate environment. The transport index of a package of radioactive material describes the highest level of radiation (in millirems per hour) that is expected at a distance of one meter (about 39.37 inches) from the surface of the package. With this information, the package can be kept safely far enough away from other packages, photographic film, live animals, or people (including yourself).

Not quite. The answer is If you're driving a placarded vehicle or a bus transporting passengers

According to federal regulations, you must stop between 15 and 50 feet of every railroad crossing if any of the following is true: (1) You're driving a bus that is carrying passengers. (2) Your vehicle is placarded for transporting hazardous materials. (3) Your vehicle has cargo tanks for hazardous materials (whether loaded or empty). (4) You're carrying any amount of chlorine.

Not quite. The answer is Name in italics

A hazardous material's proper shipping name should be displayed strictly in Roman print (no italics). Acceptable markings would include the appropriate descriptive name from the subchapter in your manual as well as UN marks, instructions, weight, ID number, specification, cautions, or some combination of the above.

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 must be signed by each carrier transporting the shipment.

A hazardous waste manifest acts as a record of everyone who has been involved in its shipment. Each copy must have all needed signatures and dates, including those of the person to whom you delivered the waste.

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 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 Hawaii Department of Transportation.

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 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 Any of the above

Under federal regulation 49 CFR 171.16, you must submit a Hazardous Materials Incident Report if an unintentional release of hazardous materials occurs. You must also submit a Hazardous Materials Incident Report if any of the following incidents occurs, even if hazmat is not released: (1) a reportable incident (death, injury, evacuation, etc.) occurs; (2) the lading retention system of a cargo tank containing hazmat is damaged; (3) undeclared hazmat is discovered; or (4) a fire, violent rupture, explosion, or dangerous evolution of heat occurs that might damage the packaging of the hazmat. Note: The "lading retention system" of a cargo tank consists of those items or pieces of equipment that provide containment of the hazmat.

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 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 the Hawaii Commercial Driver License 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 any of the above

Obviously, if there is a spill of a Class 3 material (flammable liquid) or a Class 4 material (flammable solid), you should take precautions against a fire hazard. But Class 5 materials (oxidizers) can react with some flammable substances in the area and also cause a fire. Finally, many Class 6 materials (poisons) are also flammable. Hence, it's wise to take fire precautions when dealing with Class 5 or Class 6 materials too. (Note: This topic is not usually found in the official state CDL handbook.)

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 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 any more than safety requires.

You don't want to leave a trail of hazardous materials behind you as you drive. The carrier will have to pay for the cleanup of any contaminated areas, which can be very expensive. Minimize the extent of the contamination. Move your vehicle only enough to ensure the safety of the general public. Then park your vehicle. Your vehicle and its cargo are still your responsibility, so stay with your vehicle and send someone else to get help.

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 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 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.
