Pennsylvania CDL: Hazardous Materials Practice Test

Not quite. The answer is 15 to 50

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 this, proceed once you are sure that no train is approaching, and do not shift while you are on the tracks.

Not quite. The answer is B

Marine pollutants are chemicals that are toxic to marine life. Marine pollutants, including severe marine pollutants, are listed in Appendix B to the Hazardous Materials Table. Appendix A is the List of Hazardous Substances and Reportable Quantities. There is no Appendix C or Appendix D.

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 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 are not proper shipping names.

A hazardous material's proper shipping name should be displayed strictly in Roman print (no italics).

Not quite. The answer is Yes.

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 this, proceed once you are sure that no train is approaching, and do not shift while you are on the tracks.

Not quite. The answer is The shipper

The shipping papers describe the hazardous material and its quantity, among other things. The shipper must fill out the shipping papers 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 any amount

If you are carrying any amount of chlorine gas, you must stop at every railroad crossing and be extra cautious about proceeding across. A chlorine spill from a collision with a train could be highly dangerous. Chlorine gas is poisonous. (If you're transporting chlorine in cargo tanks, you must have a gas mask with you in the cab.) Chlorine is also a strong oxidizing agent. It can react with flammable materials and start fires. The resulting fires can spread corrosive or toxic gases.

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 Send someone for help with all the necessary information.

Cleaning up a spill, a huge contamination in particular, is very expensive. Therefore, if you notice a leak, stop as soon as you possibly can and get off the road. Stay with your vehicle because of liability and safety issues and send someone else for help. You will need to send a large amount of vital information including your location, your direction of travel, the hazard class and ID numbers, your carrier's location, and the cargo's destination. Make sure you write it all down for the person seeking help.

Not quite. The answer is 300

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 Only during an emergency, to protect life or property

Normally, when your vehicle is carrying hazardous materials, you must attach the appropriate placards to the vehicle before you drive it. You are allowed to move an improperly placarded vehicle only during an emergency, to protect life or property.

Not quite. The answer is UN 1090, Acetone, 3

The basic description of hazardous materials includes the identification number, the proper shipping name, the hazard class or division, and the packing group, if any, in that order. The packing group is a grouping by the degree of danger as shown for that hazardous material in the Hazardous Materials Table. Packing Group I indicates great danger; Packing Group II, medium danger; and Packing Group III, minor danger. (The answer choices for this question do not include the packing group.)

Not quite. The answer is Class 4

Division 4.3 materials are Dangerous When Wet. An example is potassium metal. Potassium reacts with water to produce hydrogen gas. The reaction is so strong that the hydrogen gas ignites. (This effect is sometimes demonstrated in school science classes.) Under federal regulations, all materials in Classes 4 and 5 that can become dangerous when wet must be kept dry during loading, transport, and unloading.

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 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.

Not quite. The answer is 3 years; 2 years

When shipping hazardous materials, the shipper must keep a copy of the shipping papers for three years for hazardous waste, or for two years for other hazardous materials.

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 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 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.
