• Which federal agency establishes national regulations for the

transportation of hazardous materials?

A. OSHA

B. PHMSA

C. EPA

D. USCG

PHMSA issues the Hazardous Materials Regulations applicable to all modes of transportation.

2. The primary purpose of hazard communication during transport is to:

• Protect company assets
• Ensure responders know material risks
• Speed up delivery 1 / 4

• Reduce training costs

Effective communication allows responders to act safely and appropriately during incidents.

3. The DOT hazard classes are organized primarily by:

• Shipping company
• Packaging requirement
• Primary hazard posed
• Cost of transport

Hazard classes reflect the dominant risk (e.g., flammability, toxicity).

4. The ERG is primarily used:

• For long-term cleanup
• To create SDS
• During the first 30 minutes of a hazmat incident
• For waste disposal

It guides initial isolation, protective actions, and hazard recognition.

5. The function of a transportation technician includes:

• Supervising all facility employees
• Issuing CDL licenses
• Containing and controlling hazmat releases
• Authorizing interstate commerce

Technicians respond to and mitigate hazmat transportation emergencies.

• Which placard color typically represents flammable liquids? 2 / 4

• Green
• Yellow
• Red
• White

Red is universally associated with flammability hazards.

7. A UN identification number is used to:

• Track billing
• Identify the specific hazardous material
• Determine container age
• Replace SDS

UN numbers correspond to specific chemicals or chemical groups.

8. Hazardous material incompatibility occurs when:

• Materials share the same ERG guide
• Interaction increases danger
• Materials are in sealed containers
• Containers are overpacked

Incompatible substances may react violently if combined.

• Which container is most likely to carry compressed gases?
• Covered hopper
• High-pressure tube trailer
• DOT-406 cargo tank 3 / 4

• MC-331 cryogenic tank

Tube trailers transport large volumes of pressurized gases.

10. A cryogenic liquid is stored at:

• Ambient temperature

B. 0–10°C

• Extremely low temperatures

D. 100°C

Cryogens remain in liquid state only at very low temperatures.

11. The “Dangerous” placard is used when:

• The material is radioactive
• Multiple classes are present in small quantities
• Only one class is present
• Materials are nontoxic

It allows mixed loads with multiple hazard classes below placarding thresholds.

12. The first operational priority at a hazmat transportation incident is:

• Recovering product
• Life safety
• Restoring traffic
• Property conservation

Protecting responders and the public is always the primary priority.

13. The DOT requires shipping papers to be:
