CLP Hazardous Materials Transportation 5 — Questions and Answers
Question 1: You see the letters RQ in the HM column of a shipping paper entry. What do they tell you?
- The material requires a route request from the state
- The load has been restricted to rural highways
- The cargo has been re-qualified by the carrier
- The shipment contains a reportable quantity of a hazardous substance (Correct answer)
Correct answer: The shipment contains a reportable quantity of a hazardous substance
RQ means reportable quantity, so a spill of that amount or more must be reported.
Question 2: You leave your placarded truck to eat at a truck stop. Where must the hazmat shipping papers be?
- On the driver's seat or in a holder on the inside of the driver's door (Correct answer)
- In your jacket pocket so they stay with you
- Locked in the cargo compartment with the load
- In the sleeper berth storage compartment
Correct 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.
Question 3: 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 replace every placard on any mixed load
- No placards are required because neither material is a Table 1 material
- A Corrosive placard must be displayed because at least 2,205 pounds of Class 8 was loaded at one facility (Correct answer)
- A Flammable placard must be displayed because Class 3 always takes priority
Correct answer: A Corrosive placard must be displayed because at least 2,205 pounds of Class 8 was loaded at one facility
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.
Question 4: A plus sign (+) appears in column 1 of the Hazardous Materials Table beside a material's entry. What does it mean?
- The material may be shipped only by air
- The listed shipping name, hazard class, and packing group must be used even if the material does not meet that class definition (Correct answer)
- The material is safe to load with any other hazard class
- The material requires two drivers while in transit
Correct answer: The listed shipping name, hazard class, and packing group must be used even if the material does not meet that class definition
The plus sign fixes the proper shipping name, hazard class, and packing group regardless of whether the material meets the class definition.
Question 5: Two shipments of the same type of material list different packing groups, I and III. What does Packing Group I indicate?
- The lowest degree of danger
- A material packed in a single container
- A material allowed only in non-bulk packaging
- The greatest degree of danger (Correct answer)
Correct answer: The greatest degree of danger
Packing groups rank danger, with Group I being great danger, Group II medium danger, and Group III minor danger.
Question 6: You are hauling a Class 9 miscellaneous hazardous material on a domestic route. What is the placard requirement for that material?
- A Class 9 placard is not required for domestic transportation (Correct answer)
- A Class 9 placard is required for any amount
- A Class 9 placard is required only above 1,001 pounds
- A DANGEROUS placard must always replace the Class 9 placard
Correct answer: A Class 9 placard is not required for domestic transportation
Class 9 placards may be displayed on domestic shipments, but they are not required.
Question 7: A hazmat spill during transport sends a person to the hospital. Which 24-hour federal contact receives the immediate telephone report of the incident?
- The Federal Motor Carrier Safety Administration's licensing office
- The state department of motor vehicles
- The National Response Center (Correct answer)
- The Transportation Security Administration's endorsement office
Correct answer: The National Response Center
Serious hazmat incidents, including those causing hospitalization, must be reported by telephone to the National Response Center at 800-424-8802.
