Ohio CDL: Hazardous Materials Practice Test

Not quite. The answer is The proper shipping name is appropriate for describing materials for domestic transportation, but may not be proper for international transportation.

Column 1 tells which shipping mode(s) the entry affects and other information concerning the shipping description. Six different symbols may appear in Column 1 of the table. (D) Means the proper shipping name is appropriate for describing materials for domestic transportation, but may not be proper for international transportation.

Not quite. The answer is flammable materials.

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, or 4.2 (explosives, flammable liquids or solids, or spontaneously combustible materials).

Not quite. The answer is the shipper.

The shipper packs the hazardous materials for transport. The shipper must determine the correct identification number and record it on the packages and the shipping papers. (In the event of an accident, first responders are trained to look first at the packages and the shipping papers for the identification number.)

Not quite. The answer is take the appropriate steps to protect yourself and the public.

In the event of a hazardous materials emergency, take appropriate steps to keep people safe (including yourself). Limit the spread of hazardous materials, but only if you can safely do so. Let emergency response personnel know about the dangers posed by the hazardous materials. Then provide emergency responders with the shipping papers and emergency response information.

Not quite. The answer is 3,000 gallons of liquid methane

Under federal regulation 49 CFR 385.403, to transport certain amounts of certain types of hazardous materials, a carrier must obtain a Hazardous Materials Safety Permit (HMSP) from FMCSA. The hazardous materials whose transport requires an HMSP are the following: (1) Any quantity of Class 7 radioactive materials (2) More than 55 pounds of Division 1.1, 1.2, or 1.3 explosives (3) Any amount of Division 1.5 explosives that requires placarding (4) More than 1 liter or 1.08 quarts of a material that is poisonous by inhalation and meets the criteria for hazard zone A (5) A material that is poisonous by inhalation, is in bulk packaging, and meets hazard zone B (6) At least 3,500 gallons of a material that is poisonous by inhalation and meets hazard zone C or D (7) Compressed or refrigerated liquid gas (such as methane or natural gas) in bulk packaging with a capacity of at least 3,500 gallons There must be a copy of the HMSP in the CMV that is transporting the materials. (Note: This topic is not usually found in the official state CDL handbook.)

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 At least 300 feet

When driving with a load of Division 1.1, 1.2, or 1.3 hazardous materials, which are explosives, you must park at least 300 feet away from any bridge, tunnel, or structure. You must maintain the same distance from any gathering place or open fire.

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 Do both of the above.

If there is an emergency involving the hazardous materials that you're transporting, follow all instructions that your employer gave you. Keep bystanders away, preferably upwind, while warning them of the danger. Try to keep open flames away and don't let anyone smoke near the hazardous materials. Take a copy of your shipping papers with you to provide to first responders who arrive at the scene.

Not quite. The answer is a common carrier must never transport the material.

If a material is listed as "Forbidden" in column 3 of the Hazardous Materials Table, you must not transport any amount of that material. An example is silver fulminate (dry), an extremely sensitive explosive. (It's so sensitive that a sufficiently large quantity will explode under its own weight.)

Not quite. The answer is On the driver's seat whenever you are out of the vehicle

Your shipping papers for hazardous materials must be visible and accessible to emergency personnel at all times, including when you are out of the vehicle. Therefore, whenever you are away from your vehicle, they must be left on the driver's seat, within easy reach in case of an emergency.

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 None of the above

According to federal regulation 49 CFR 397.13, no one is allowed to smoke or carry a lighted cigarette, cigar, or pipe, within 25 feet of a truck that transported Class 3 materials (flammable liquids) or Division 2.1 materials (flammable gases). This rule applies even after the truck was emptied of these hazardous materials.

Not quite. The answer is 10

All placarded vehicles are required to have a fire extinguisher with a minimum UL rating of 10 B:C. That is, it must be able to extinguish a 10-square-foot class B fire (which includes almost all flammable liquids) and be electrically non-conductive (hence its C rating).

Not quite. The answer is The identification number

The hazardous material identification number is a four-digit code used by first responders to identify the material, should an accident occur. The identification number must appear first on the shipping paper as part of the shipping description.

Source: 49 CFR § 172.202

Not quite. The answer is make it easy to identify.

The regulations for packages of hazardous materials require shippers to make it easy for drivers, destination personnel, and emergency personnel to identify the contents quickly and easily.

Not quite. The answer is The shipper

The shipping paper describes the hazardous material and its quantity, among other things. The shipper must fill out the shipping paper because the shipper packages the material. Only the shipper knows exactly what's inside the package. Except in an emergency, no one else should open the package to see what's inside until the package is delivered to the receiver.

Not quite. The answer is Placards for both poisons and flammable materials

There are two placard tables, Table 1 and Table 2. Table 1 materials must be placarded whenever any amount is transported. Table 2 materials must be placarded whenever at least 1,001 pounds is transported. Therefore, when you transport a small amount of poison and 1,001 pounds or more of flammable materials, you need placards for both poisons and flammable materials.

Not quite. The answer is keep all people far away and upwind of the accident.

If you have an accident while carrying hazardous materials, you must follow your employer's instructions. However, keep bystanders well away and upwind of the accident for their own safety.

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.
