Sample Connecticut HazMat Test Questions

Question 1

Except for bulk packaging and other special exceptions, when do Table 2 materials such as combustible liquid require placards?

  1. A At 100 pounds aggregate gross weight
  2. B At 454 pounds aggregate gross weight
  3. C At 1,001 pounds or more aggregate gross weight
  4. D In any amount

Correct answer: C – At 1,001 pounds or more aggregate gross weight

The Connecticut CDL manual summarizes the federal placarding rule: except for bulk packaging, Table 2 materials generally require placards at an aggregate gross weight of 1,001 pounds or more. Combustible liquid appears in Table 2. Bulk packaging and materials covered by other special placarding provisions are not included in the less-than-1,001-pound exception.

Question 2

For a non-exclusive-use vehicle carrying Class 7 radioactive packages, what is the maximum total transport index?

  1. A 10
  2. B 25
  3. C 50
  4. D 100

Correct answer: C – 50

The total transport index for Class 7 packages and overpacks in a non-exclusive-use transport vehicle may not exceed 50. The total is calculated by adding the transport index numbers shown on the individual labels. The federal rule provides an exception for specified exclusive-use shipments, so the 50 limit should not be stated without that qualification.

Question 3

Which statement best describes the Emergency Response Guidebook (ERG)?

  1. A It is a complete inventory of hazardous materials carried by commercial drivers.
  2. B It provides procedures for responding to weather-related disasters.
  3. C It addresses only emergencies involving radioactive materials.
  4. D It helps emergency responders and industry workers protect themselves and the public during hazardous materials incidents.

Correct answer: D – It helps emergency responders and industry workers protect themselves and the public during hazardous materials incidents.

The Connecticut Commercial Driver License Manual describes the ERG as a hazardous materials guide for firefighters, police, and industry personnel. It is indexed by proper shipping name and identification number. Those entries help responders identify the material and find initial protective and emergency-response information.

Question 4

What does “RQ” next to a hazardous material’s basic description indicate?

  1. A The package contains only one type of 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 hazardous substance at or above its reportable quantity.

Correct answer: D – The package contains a hazardous substance at or above its reportable quantity.

Under federal hazardous materials rules, RQ identifies a hazardous substance contained in one package at or above its listed reportable quantity. The letters may appear before or after the basic description on the shipping paper. A release involving a reportable quantity may trigger incident-reporting requirements.

Question 5

Which placement rule for hazardous materials shipping papers is correct?

  1. A They may be stored anywhere inside the vehicle.
  2. B Keep them in the driver-door pouch or clearly visible within immediate reach while belted; when away, leave them in the pouch or on the driver’s seat.
  3. C They must remain in the driver-door pouch at all times.
  4. D They must always be held in the driver’s hand while driving.

Correct answer: B – Keep them in the driver-door pouch or clearly visible within immediate reach while belted; when away, leave them in the pouch or on the driver’s seat.

Federal rules require shipping papers to be readily accessible and recognizable. While driving, they must be visible within immediate reach while the driver is restrained, or stored in the driver-door pouch. When the driver leaves the cab, they must be placed on the driver’s seat or in the door pouch, as explained in the Connecticut manual.

Question 6

Which sequence shows the correct order for a hazardous material’s basic description?

  2. B Hazard class, identification number, proper shipping name, packing group
  3. C Identification number, proper shipping name, hazard class or division, packing group if required
  4. D Proper shipping name, identification number, packing group, hazard class

Correct answer: C – Identification number, proper shipping name, hazard class or division, packing group if required

Federal shipping-paper rules place the identification number first, followed by the proper shipping name and hazard class or division. The packing group follows when one is assigned. A packing group is shown as a Roman numeral and may be preceded by “PG.”
