Sample South Carolina HazMat Test Questions

Question 1

A cargo tank is unloading Division 2.1 flammable gas using an engine-driven transfer pump, and the hose has no shutoff valve at its discharge end. When must the engine be stopped?

  1. A Before product transfer begins
  2. B After the transfer hose has been disconnected
  3. C After product transfer ends but before the connections are disconnected
  4. D The engine may remain running throughout disconnection

Correct answer: C – After product transfer ends but before the connections are disconnected

Federal hazardous-materials rules allow the engine to run while it operates the vehicle’s transfer pump. If the delivery hose lacks a shutoff valve at its discharge end, the engine must be stopped when loading or unloading finishes and remain stopped while the connections are disconnected. This prevents the pump from operating during disconnection.

Question 2

Unless an authorized pumping-equipment exception applies, what must you do before loading Class 1 explosives?

  1. A Turn off the vehicle’s engine
  2. B Keep the engine running at idle
  3. C Use metal tools to handle the packages
  4. D Begin loading before inspecting the cargo space

Correct answer: A – Turn off the vehicle’s engine

Federal hazardous-materials rules prohibit loading or unloading Class 1 explosives while the vehicle’s engine is running, subject to limited pumping-equipment exceptions. South Carolina’s CDL manual directs drivers to turn off the engine and then inspect the cargo space. It also warns against sharp projections and requires appropriate flooring for certain explosive divisions.

Question 3

What penalties can violations of hazardous-materials containment requirements carry?

  1. A Transportation delays only
  2. B Only a warning for the first violation
  3. C Civil fines and, for qualifying criminal violations, imprisonment
  4. D Higher insurance premiums only

Correct answer: C – Civil fines and, for qualifying criminal violations, imprisonment

Federal law permits civil penalties for knowing violations of hazardous-materials requirements. A person who willfully or recklessly violates those requirements may face a criminal fine, imprisonment, or both. The CDL manual accordingly warns that noncompliance can result in fines and jail.

Source: South Carolina Commercial Driver’s License Manual — § 9.1.3, “Assure Safe Drivers and Equipment”, 49 U.S.C. § 5123 – Civil penalty, 49 U.S.C. § 5124 – Criminal penalty

Question 4

The Emergency Response Guidebook is primarily intended to:

  1. A Teach commercial drivers how to handle curves
  2. B Help emergency personnel respond to hazardous-materials incidents
  3. C Assign approved hazardous-materials routes
  4. D Replace the shipment’s required shipping papers

Correct answer: B – Help emergency personnel respond to hazardous-materials incidents

The South Carolina CDL manual describes the ERG as a Department of Transportation guide for firefighters, police, and industry workers. It helps them protect themselves and the public when responding to hazardous materials. It is not a routing guide or a substitute for shipping papers.

Question 5

Where must each required placard generally appear on a hazardous-materials transport vehicle?

  1. A On the rear only
  2. B On the front and rear only
  3. C Twice on the front and twice on the rear
  4. D On the front, rear, and both sides

Correct answer: D – On the front, rear, and both sides

Federal placarding rules generally require the applicable placard on each side and each end of the transport vehicle. This produces four placements: front, rear, left side, and right side. Placards must also be displayed so they can be readily seen from the direction they face.

Source: South Carolina Commercial Driver’s License Manual — § 9.3.10, “Placarding”, 49 CFR § 172.504(a) – General placarding requirements

Question 6

Which statement best describes the Emergency Response Guidebook?

  1. A It is a complete inventory of every hazardous material a driver may haul
  2. B It covers evacuation procedures for natural disasters only
  3. C It addresses only incidents involving radioactive cargo
  4. D It helps responders protect themselves and the public during hazardous-materials incidents

Correct answer: D – It helps responders protect themselves and the public during hazardous-materials incidents

The ERG supplies initial-response information for firefighters, police, and industry personnel dealing with hazardous materials. It can be searched using a material’s proper shipping name or identification number. Those identifiers should also appear correctly on the shipment’s required documents and markings.
