  1. Why do hazardous-material transportation rules address both packaging and hazard communication?

    Correct answer: Packages contain the material; markings and papers communicate its hazards.

    A safe package helps prevent release. Accurate descriptions, labels, markings and placards help workers and responders recognize the hazards.

  2. Who normally classifies a shipment and supplies its proper shipping description before the carrier accepts it?

    Correct answer: The shipper offering the material.

    The shipper identifies the material and prepares the required packaging and hazard communication. Carrier and driver checks remain necessary.

  3. A shipment's paperwork looks correct, but required hazard markings are missing from its packages. What should the driver do?

    Correct answer: Have the shipment brought into compliance before accepting it.

    The handbook assigns carriers responsibility to refuse improper shipments. Shipping papers, package markings and labels serve different purposes and must agree.

  4. What does a material's hazard class communicate?

    Correct answer: The kind of transportation hazard assigned to the material.

    Hazard classes organize materials by their transportation hazards. They are not cargo-value or driver-experience ratings.

  5. Which Hazardous Materials Table column gives the proper shipping name?

    Correct answer: Column 2.

    Column 2 provides the hazardous-material descriptions and proper shipping names. The proper shipping name is shown in ordinary Roman print, not the italic descriptive text.

  6. Where does the Hazardous Materials Table identify required hazard labels?

    Correct answer: Column 6.

    Column 6 indicates label requirements. This is separate from the identification number in Column 4 and packaging instructions in Column 8.

  7. Two hazardous products each have correct papers. What else must be checked before placing them together in the same cargo space?

    Correct answer: Whether the applicable segregation rules allow that combination.

    Properly documented products can still be incompatible. The handbook points to the federal segregation rules; documentation alone does not authorize mixed loading.

  8. What information is especially useful when someone contacts responders about your hazardous-cargo incident?

    Correct answer: Exact location, incident details and known shipment identification.

    Give the exact location and direction of travel, what happened, carrier details and known proper shipping name, class and identification number. Do not approach the hazard merely to gather missing information.
