Which statement correctly applies the federal rules on when a carrier must hold a Hazardous Materials Safety Permit (HMSP)?

Correct answer: Hauling liquid methane in a bulk tank with a capacity of 3,000 gallons does not require an HMSP.

Answer options

  1. AHauling a highway route-controlled quantity of Class 7 material does not require an HMSP
  2. BHauling 30 pounds of a Division 1.1 explosive requires an HMSP
  3. CHauling liquid methane in a bulk tank with a capacity of 3,000 gallons does not require an HMSP Correct

Why

Only certain high-risk shipments require an HMSP, including a highway route-controlled quantity of radioactive material, more than 55 pounds of Division 1.1 explosives, and liquefied methane in bulk packaging with a capacity of 3,500 gallons or more. A bulk tank with a 3,000-gallon capacity is below that threshold, and 30 pounds of a Division 1.1 explosive is under the 55-pound limit.
