✍️ Sample HAZMAT Questions & Answers
1. How must a driver handle a hazmat shipping paper when they leave the truck unattended?
When the driver is out of the cab, shipping papers must be in a pouch on the driver's door or on the driver's seat so emergency responders can find them quickly.
2. A flammable liquid has a flash point greater than 200 degrees (F).
This statement is false. By definition, a flammable liquid has a flash point *below* 100°F (37.8°C), meaning it ignites easily at relatively low temperatures. Liquids with a flash point at or above 100°F but below 200°F (93.3°C) are classified as combustible liquids. A flash point greater than 200°F indicates a material with a very low flammability hazard, far from the definition of a flammable liquid.
3. What must a driver do before transporting Division 1.3 (incendiary) explosives?
Transporting Division 1.3 and other explosives requires the vehicle to have proper permits and the route to be pre-approved by authorities.
4. Which document must accompany a hazardous materials shipment throughout the entire trip?
Shipping papers (bill of lading, manifest, or equivalent) must travel with the hazmat shipment and be accessible to emergency responders.
5. What does 'RQ' on a shipping paper indicate?
'RQ' stands for Reportable Quantity — a release of this substance in the listed quantity or greater must be reported to the National Response Center.
6. In HazMat combination packaging, how is an outer fiberboard box classified?
A fiberboard box used to surround and protect inner receptacles in a combination package is classified as outer packaging under 49 CFR.
