CDL · Hazardous materials

The words 'INHALATION HAZARD' appear on the shipping paper or on a package in your load. What are you required to do?

Correct answer: Display a POISON INHALATION HAZARD or POISON GAS placard in addition to the other required placards.

Answer options

  1. AKeep the total amount of that material on the vehicle below 2,000 pounds
  2. BDisplay a POISON INHALATION HAZARD or POISON GAS placard in addition to the other required placards Correct
  3. CSwap the other placards for a single DANGEROUS placard once the load passes 1,001 pounds

Why

A shipment marked 'INHALATION HAZARD' needs a POISON GAS or POISON INHALATION HAZARD placard, whichever applies, together with the placards its hazard class already requires, even for small amounts. A DANGEROUS placard cannot substitute for it, and limiting the weight of the load does not remove the requirement.
