Sample Texas HazMat Test Questions

Question 1

What does a “D” in Column 1 of the Hazardous Materials Table indicate?

  1. A The listed proper shipping name is intended only for international transportation
  2. B The proper shipping name is appropriate domestically but may be inappropriate internationally
  3. C One or more technical names must be added in parentheses
  4. D The material is regulated only when transported by vessel

Correct answer: B – The proper shipping name is appropriate domestically but may be inappropriate internationally

Federal hazardous materials regulations use “D” to identify proper shipping names that are appropriate for domestic transportation but may be inappropriate under international regulations. An alternate proper shipping name may be selected when domestic or international transportation is involved. The “G” and “W” symbols have different meanings.

Question 2

While a hazmat driver is at the vehicle’s controls, which listed location is permitted for the shipping papers?

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

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

Federal regulations require the papers to be within the driver’s immediate reach while the driver is belted and either readily visible to someone entering the compartment or in a holder mounted inside the driver’s-side door. Thus, the door holder is one permitted location for a Texas hazmat driver. When away from the controls, the papers must be in that holder or on the driver’s seat.

Question 3

A Class 3 flammable liquid is being loaded into a cargo tank through an open filling hole. How must the bonding or grounding connection be used?

  1. A Connect it after filling starts and remove it before closing the hole
  2. B Connect it before opening the filling hole and keep it connected until after the last filling hole is closed
  3. C Use it only when unloading the cargo tank
  4. D It is unnecessary if the vehicle's engine is off

Correct answer: B – Connect it before opening the filling hole and keep it connected until after the last filling hole is closed

Federal rules require the connection to be made before an open filling hole is opened and maintained until after the last filling hole is closed. This reduces the possibility of static electricity igniting flammable vapor. The Texas handbook presents the same procedure for open-hole cargo-tank loading.

Question 4

What should a hazardous-materials driver do at the scene of a crash involving the load?

  1. A Continue driving until reaching a service facility
  2. B Keep people away, communicate the hazard, and call for assistance
  3. C Begin unloading the hazardous materials
  4. D Move the vehicle to an isolated location regardless of conditions

Correct answer: B – Keep people away, communicate the hazard, and call for assistance

Keep people away from the scene and inform emergency responders about the hazardous material. Limit a spill only when that can be done safely, and do not touch leaking material. If material is escaping from the vehicle, move it no farther than safety requires and call for help.

Question 5

A vehicle containing hazardous materials must not be parked within how many feet of an open fire?

  1. A 100 feet
  2. B 200 feet
  3. C 300 feet
  4. D 500 feet

Correct answer: C – 300 feet

Federal rules prohibit parking a motor vehicle containing hazardous materials within 300 feet of an open fire. A driver also may not operate near an open fire without first determining that the vehicle can pass safely without stopping. The Texas handbook emphasizes the same 300-foot parking distance.

Question 6

How often must a hazmat employee receive recurrent hazardous-materials training?

  1. A Every year
  2. B At least once every three years
  3. C Every five years
  4. D Only when requested by the employer

Correct answer: B – At least once every three years

Federal hazardous-materials regulations require recurrent training at least once every three years. The training must address the applicable general-awareness, function-specific, safety, and security subjects. Employers remain responsible for compliance and must maintain the required training records.
