  1. If the words 'Inhalation Hazard' appear on a shipping paper, which placard must always be displayed regardless of quantity?

    Answer: Poison Inhalation Hazard

    Any material identified as an inhalation hazard (Zone A, B, C, or D) requires the 'Poison Inhalation Hazard' placard regardless of the quantity being transported.

  2. What information is NOT required on a basic HazMat shipping paper entry?

    Answer: Driver's CDL number

    The driver's CDL number is not part of the required HazMat shipping paper entry; the required elements are the UN/NA number, proper shipping name, hazard class, packing group, and quantity.

  3. A tanker displaying a four-digit number inside an orange panel is using which identification system?

    Answer: UN/NA Identification Number System

    Orange panels with four-digit UN/NA identification numbers are used on bulk tanks to identify the specific hazardous material inside, allowing emergency responders to consult the ERG.

  4. Under HazMat rules, a driver must check tires on a vehicle transporting hazardous materials:

    Answer: At the start of each trip and at least once during the trip

    HazMat regulations require the driver to examine tires at the start of the trip and at least once during the trip to catch flats, overheating, or other defects.

  5. Which of the following is an example of a Division 6.1 material?

    Answer: Arsenic trioxide

    Division 6.1 covers toxic (poisonous) materials; arsenic trioxide is a classic example, while the others are classified as flammable gas, corrosive, and oxidizer respectively.

  6. What does the 'Z' suffix on a proper shipping name (e.g., 'Flammable liquid, n.o.s. (Z)') indicate?

    Answer: The material is a severe marine pollutant

    A 'Z' suffix following a proper shipping name designates the material as a severe marine pollutant under DOT regulations, requiring special notation.

  7. During a routine stop, a HazMat driver notices the temperature of the cargo area feels unusually hot. What should the driver do?

    Answer: Park away from people and structures, do not open doors, and call for help

    An unusually hot cargo area may indicate a fire or chemical reaction; the driver should park at a safe distance from people and structures, avoid opening the doors, and immediately call emergency services.
