Sample Maine HazMat Test Questions

Question 1

Unless an applicable packaging or separation exception is met, food or animal feed must not be transported in the same vehicle with a package bearing which label?

  1. A FLAMMABLE LIQUID
  2. B EXPLOSIVE
  3. C POISON or POISON INHALATION HAZARD
  4. D FLAMMABLE GAS

Correct answer: C – POISON or POISON INHALATION HAZARD

Federal hazardous materials regulations generally prohibit transporting a package bearing a POISON or POISON INHALATION HAZARD label with food, feed, or other edible material in the same vehicle. Specified overpacking, closed-unit-load, and Packing Group III separation exceptions may apply. Packages bearing certain poison labels are also prohibited in the driver’s compartment or sleeper berth.

Question 2

When using a paper hazardous-waste manifest, what must the transporter do before leaving the generator’s property?

  1. A Sign and date the manifest, return a signed copy to the generator, and ensure the manifest accompanies the shipment
  2. B Wait until delivery before signing any copy
  3. C Carry the manifest without acknowledging receipt of the waste
  4. D Complete a manifest only if waste is spilled during transportation

Correct answer: A – Sign and date the manifest, return a signed copy to the generator, and ensure the manifest accompanies the shipment

Federal hazardous-waste rules require a transporter to sign and date the manifest before transporting the waste, return a signed copy to the generator, and ensure the manifest accompanies the shipment. At delivery, the transporter obtains the recipient’s signature and retains a copy. Proper electronic manifests may satisfy signing and carrying requirements, subject to the applicable highway shipping-paper provisions.

Question 3

Which material may not be described on a shipping paper with a hazard class or UN/NA identification number from the Hazardous Materials Table?

  1. A A hazardous substance in a reportable quantity
  2. B A regulated hazardous material below its reportable-quantity threshold
  3. C A hazardous waste
  4. D A material not regulated as hazardous

Correct answer: D – A material not regulated as hazardous

Federal shipping-paper rules generally prohibit describing a non-hazardous material with a hazard class or identification number listed in the Hazardous Materials Table. Those entries communicate regulated hazards to carriers and emergency responders. Using them for ordinary, non-hazardous cargo could create a false hazard warning.

Question 4

What does “RQ” beside a hazardous-material description on a shipping paper indicate?

  1. A The package contains no other material
  2. B The shipment has a declared value above $1,000
  3. C The material is exempt from incident reporting
  4. D The package contains a reportable quantity of a hazardous substance

Correct answer: D – The package contains a reportable quantity of a hazardous substance

“RQ” means reportable quantity and is placed before or after the basic description when the required quantity is present in one package. It identifies a hazardous substance subject to a specified release-reporting threshold. If a release equals or exceeds that threshold, the person in charge must promptly notify the National Response Center under federal rules.

  3. C The vehicles must remain connected for 45 minutes
  4. D All explosives must be removed and placed at least 200 feet from the vehicles and occupied buildings

Correct answer: D – All explosives must be removed and placed at least 200 feet from the vehicles and occupied buildings

Maine’s CDL manual directs drivers to warn others, keep bystanders away, and prevent smoking or open flames after an explosives accident. All explosives must be removed before collision vehicles are separated. The explosives should be placed at least 200 feet from the vehicles and occupied buildings, and people should remain a safe distance away.

  3. C Immediately unload the hazardous materials
  4. D Move the damaged vehicle to a secluded location

Correct answer: B – Keep people away, warn them of the danger, and call for help

The Maine CDL manual instructs the driver to keep people far from the scene and upwind, warn others about the danger, and call for help. Shipping papers and emergency-response information should be kept available for responders. The driver should attempt to limit a release only when that can be done safely.
