Hazardous Materials Transportation Flashcards

You see the letters RQ in the HM column of a shipping paper entry. What do they tell you?

RQ means reportable quantity, so a spill of that amount or more must be reported.

You leave your placarded truck to eat at a truck stop. Where must the hazmat shipping papers be?

Answer: On the driver's seat or in a holder on the inside of the driver's door

When you are away from the vehicle, the papers must be on the driver's seat or in a holder mounted on the inside of the driver's door so responders can find them.

At one loading facility, you load 1,500 pounds of a Class 3 material and 2,500 pounds of a Class 8 material. You want to use a DANGEROUS placard. What rule applies?

DANGEROUS may be used for mixed Table 2 loads, except that a category with 2,205 pounds or more loaded at one facility needs its own placard.

A plus sign (+) appears in column 1 of the Hazardous Materials Table beside a material's entry. What does it mean?

The plus sign fixes the proper shipping name, hazard class, and packing group regardless of whether the material meets the class definition.
