Sample Massachusetts HazMat Test Questions

Question 1

Where is the required shipper’s certification for a hazardous-material shipment placed?

  1. A On the shipping paper containing the required hazardous-material description
  2. B On each individual package
  3. C On the vehicle placards
  4. D On the emergency-response guidebook

Correct answer: A – On the shipping paper containing the required hazardous-material description

Federal hazardous materials regulations generally require the offeror to print the certification on the shipping paper containing the required hazardous-material description. The certification states that the material has been properly classified, described, packaged, marked, and labeled and is in proper condition for transportation. It must also be signed as specified by the regulation unless an exception applies.

Question 2

What is the required shape and minimum side length of a standard hazardous-material placard?

  1. A An oval at least 250 mm long
  2. B A square displayed flat, at least 250 mm on each side
  3. C A circle at least 250 mm in diameter
  4. D A square-on-point diamond, at least 250 mm (9.84 inches) on each side

Correct answer: D – A square-on-point diamond, at least 250 mm (9.84 inches) on each side

Federal hazardous materials regulations require a standard placard to be a square-on-point diamond measuring at least 250 mm, or 9.84 inches, on each side. Its design must also include the prescribed printing and inner border. Massachusetts incorporates the federal hazardous-material transportation regulations for covered operations on public ways.

Question 3

While you are at the controls of a vehicle carrying hazardous materials, which is an approved location for the shipping papers?

  1. A In a holder mounted inside the driver-side door
  2. B Inside a closed glove compartment
  3. C Under the driver’s seat
  4. D In the cargo compartment

Correct answer: A – In a holder mounted inside the driver-side door

Federal rules require the shipping papers to remain within the restrained driver’s immediate reach. They must also be readily visible to someone entering the compartment or kept in a holder mounted inside the driver-side door. The Massachusetts manual refers to this door-mounted holder as a pouch and emphasizes quick access after an incident.

Question 4

What does the transport index shown on a Class 7 radioactive-material package indicate?

  1. A The package’s gross weight
  2. B The degree of control the carrier must exercise during transportation
  3. C The number of radioactive items inside the package
  4. D The package’s required delivery time

Correct answer: B – The degree of control the carrier must exercise during transportation

The transport index is a dimensionless number placed on a radioactive-material package label. It designates the degree of control the carrier must exercise during transportation and is calculated from the radiation level measured at a specified distance from the package. It is not a measurement of package weight or contents.

Question 5

What do shippers place on most hazardous-material packages to communicate the type of hazard?

  1. A Diamond-shaped hazard warning labels
  2. B The shipment’s total weight only
  3. C The destination address only
  4. D The carrier’s insurance information

Correct answer: A – Diamond-shaped hazard warning labels

Federal rules require applicable hazardous-material packages to display the labels specified for the material. These diamond-shaped warning labels identify hazards such as flammable gas, poison, radioactive material, or corrosive material. The labels belong on the package or an authorized attached tag—not on the shipping paper itself.

Question 6

Which statement correctly describes how compressed-gas cylinders must be loaded?

  1. A They must always be placed horizontally without restraints
  2. B They may be left loose if the cargo floor is flat
  3. C They must be restrained, racked, or boxed to prevent shifting, overturning, or ejection
  4. D They may be supported only by other cargo

Correct answer: C – They must be restrained, racked, or boxed to prevent shifting, overturning, or ejection

Federal hazardous-materials rules permit Class 2 cylinders to be secured in an upright or horizontal position, loaded in racks, or packed in boxes or crates. The loading method must prevent shifting, overturning, or ejection under normal transportation conditions. If a Division 2.1 cylinder has a pressure-relief device, that device must communicate with the vapor space.
