Sample North Carolina HazMat Test Questions

Question 1

Why should hazardous-materials shipping papers be tabbed or placed first in a stack of papers?

  1. A To make them quickly recognizable and available after an accident or inspection
  2. B To keep the cargo from shifting
  3. C To replace the required emergency-response information
  4. D To show that the shipment does not require placards

Correct answer: A – To make them quickly recognizable and available after an accident or inspection

Hazardous-materials shipping papers must be readily available and recognizable to authorities during an accident or inspection. If carried with other documents, they must be distinctly tabbed or placed first. This allows responders to identify the materials and obtain the information needed to address the hazards involved.

Question 2

What is the primary purpose of the Emergency Response Guidebook?

  1. A To provide normal vehicle-operating instructions
  2. B To provide incident-response guidance for protecting responders and the public
  3. C To designate required truck routes
  4. D To explain CDL licensing procedures

Correct answer: B – To provide incident-response guidance for protecting responders and the public

In North Carolina commercial operations, the ERG serves as an emergency reference for firefighters, police, and industry personnel. It provides guidance for protecting responders and the public during hazardous-material incidents. The guide is organized so materials can be located by their proper shipping names or identification numbers.

Question 3

What should a driver do at the scene of a hazardous-materials incident?

  1. A Leave the shipping papers on the driver’s seat and walk away
  2. B Keep people away and warn them about the danger
  3. C Try to contain the material regardless of the risk
  4. D Ask untrained bystanders to help clean up the material

Correct answer: B – Keep people away and warn them about the danger

Keep people far from the scene, preferably upwind, and warn them of the danger. Limit the spread of the material only if you can do so safely. Call for help, retain the shipping papers, and provide emergency responders with the shipping papers and emergency-response information when they arrive.

Question 4

Which description correctly defines a safe haven?

  1. A Any rest area where a placarded vehicle may be left unattended
  2. B An area approved in writing for parking unattended vehicles carrying Division 1.1, 1.2, or 1.3 explosives
  3. C A storage site used only for radioactive materials
  4. D Any carrier terminal with driver sleeping facilities

Correct answer: B – An area approved in writing for parking unattended vehicles carrying Division 1.1, 1.2, or 1.3 explosives

A safe haven is an area specifically approved in writing by local, state, or federal governmental authorities. It is used for parking unattended vehicles containing Division 1.1, 1.2, or 1.3 explosives. An ordinary truck stop, rest area, or parking lot does not become a safe haven merely because a driver considers it secure.

Question 5

Which hazard class uses transport indexes to control package loading and separation?

  1. A Class 2
  2. B Class 5
  3. C Class 7
  4. D Class 8

Correct answer: C – Class 7

Transport indexes are used with certain Class 7 radioactive-material packages. They indicate the degree of control required for package grouping and separation from people, animals, and undeveloped film. In non-exclusive-use transportation, the total transport index for packages in a vehicle or single group generally may not exceed 50; separate provisions apply to exclusive-use shipments.

  2. B Exactly 250 mm in diameter and oval-shaped
  3. C At least 200 mm wide and rectangular
  4. D At least 10¾ inches across and circular

Correct answer: A – At least 250 mm on each side and displayed as a square-on-point diamond

A standard placard must be diamond-shaped, also described as square-on-point. Each side must measure at least 250 mm, or approximately 9.84 inches. The placard also has a solid inner border positioned approximately 12.5 mm inside and parallel to its outer edge.
