Oregon CDL: Hazardous Materials Practice Test

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 "Explosives" placards.

The Placard Tables (which you'll find in the Oregon Commercial Driver's Manual) describe which materials must be placarded and what the placards must say. Explosives are in Placard Table 1, so your vehicle must have placards that say "Explosives" followed by the division number (1.1, 1.2, or 1.3).

Not quite. The answer is Any of the above

Federal regulation 49 CFR 392.10 states that CMVs transporting any of the following must stop at all railroad crossings: (1) Most hazardous materials that require placarding (see the regulation for details). (2) Any amount of chlorine. (3) A cargo tank that is used to carry hazmat, even if it is currently empty. (4) A cargo tank containing a substance whose temperature at the time of loading was already above its flashpoint.

Not quite. The answer is must put the word "WASTE" before the proper shipping name of the material on the shipping paper.

A shipper of hazardous wastes must put the word "WASTE" before the proper shipping name of the material on the shipping paper (hazardous waste manifest). Federal regulations require shippers to put hazard warning labels on packages and provide proper shipping papers, emergency response information, and placards, regardless of whether the material being shipped is waste.

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 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 All of the above

The Hazardous Materials Regulations accomplish several things. They help ensure safe drivers and equipment. They communicate the risk of hazardous materials through the use of appropriate labels, placards, and shipping papers. Also, the regulations tell shippers how to package the materials safely, and they tell drivers how to load, transport, and unload the materials. These rules are called "containment rules."

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 Any of the above

Most official state CDL handbooks still state that to oversee the loading or unloading of hazmat into a cargo tank, a qualified person must be within 25 feet of the cargo tank, with a clear view of the cargo tank. However, this is no longer the only way. Federal regulation 49 CFR 177.834 now allows two methods by which the qualified person can "attend" the loading or unloading remotely: (1) via a video monitoring system, as long as the cameras provide an unobstructed view of all equipment involved in the loading or unloading process; (2) via an instrumentation and signaling system, as long as the system provides a surveillance capability that is as good as that of a human observer. When a qualified person is "attending" remotely, there must be a way for the person to control the shut-off valves remotely in the event of an incident. There must also be a way for the person to terminate the loading or unloading immediately in the event of a loss of monitoring capability. Finally, when the loading or unloading has been completed, some qualified person (not necessarily the same one) must inspect the cargo tank in person for any damage that might have been sustained during the loading or unloading process. (Note: This topic is not found in the official state CDL handbook.)

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.

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 To communicate risk

Placards are signs posted on the outside of the vehicle to warn others about hazardous materials. These signs identify the hazard class of the cargo.

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 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 have their drivers text their locations.

To communicate the risk of hazardous materials, regulations require shippers to put placards on trucks, put hazard warning labels on packages, provide proper shipping papers, and supply emergency response information. Regulations don't usually require regular texting. In fact, in many states, texting on a handheld cell phone while driving is illegal.

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 20 feet long.

An ISO standard portable tank is a metal tank enclosed in a steel frame. The frame is 19.8556 feet (6.05 meters) long, 7.874 feet (2.40 meters) wide, and either 7.874 feet (2.40 meters) high or 8.374 feet (2.55 meters) high.

Not quite. The answer is MC-306 (DOT-406)

MC-306 (DOT-406) cargo tanks carry liquids under very low or no pressure (maximum allowable pressure of 3 psi for MC-306 and 4 psi for DOT-406). The cargo tank has an oval or elliptical cross section and is usually compartmented. These tanks are commonly used to carry gasoline, diesel fuel or fuel oil, and other flammable liquids.

Not quite. The answer is All of the above

The hazardous materials regulations (HMR) don't just apply to the movement of hazmat. These regulations also apply to those operations that are considered incidental to the movement of hazmat. Such operations include loading and unloading, blocking and bracing, and segregating hazmat from incompatible cargo. For bulk packaging transported by road, the HMR also apply to the transloading (transfer) of hazmat from one bulk package to another; and to the emptying of hazmat from the bulk package, upon delivery to the receiver.

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.)
