A driver is transporting 1,500 pounds of UN1830, Sulfuric acid (Class 8, PG II) in non-bulk packages. What type of placard is required on the vehicle?
- AFLAMMABLE
- BDANGEROUS
- CCORROSIVE
- DPOISON
Show answer & explanationAnswer & explanation
Correct answer: C. CORROSIVE
Sulfuric acid is a Class 8 (Corrosive) material. Class 8 materials are listed in Placarding Table 2. Since the quantity (1,500 pounds) exceeds the 1,001-pound threshold for Table 2 materials, a placard is required. For a single hazardous material that requires placarding, the specific hazard class placard (CORROSIVE) must be displayed.
Why the other options are wrong
- A. Flammable is for Class 3 materials, which sulfuric acid is not.
- B. The 'DANGEROUS' placard is typically used for mixed loads of Table 2 materials, not for a single material over its threshold.
- D. Poison is for Class 6.1 or 2.3 materials, which sulfuric acid is not.
Specific Placard for Single Table 2 Material
When a single hazardous material from Placarding Table 2 is transported in a quantity of 1,001 pounds or more, the transport vehicle must display the specific placard corresponding to that material's hazard class.
- Applies to Table 2 materials.
- Quantity must be 1,001 lbs or more.
- Display the exact placard for the hazard class.
- Distinguishes from the 'DANGEROUS' placard for mixed loads.
Memory trick: Over a thousand of one kind? Give it its own placard, you'll find!
