- ANON-FLAMMABLE GAS placard, with the UN1075 identification number.
- BFLAMMABLE GAS placard, without an identification number.
- CFLAMMABLE GAS placard, with the UN1075 identification number.
- DNo placard is required as the weight is under 1,001 pounds.
Show answer & explanationAnswer & explanation
Correct answer: C. FLAMMABLE GAS placard, with the UN1075 identification number.
Liquefied Petroleum Gas (UN1075) is a Class 2.1 Flammable Gas. According to placarding regulations, any quantity of a Class 2.1 Flammable Gas, regardless of weight (Table 1 material), requires a FLAMMABLE GAS placard. Furthermore, when transporting only one hazardous material, or if the material is a Table 1 material, the identification number must be displayed on the placard or an orange panel.
Why the other options are wrong
- A. LP-Gas is a Flammable Gas, not a Non-Flammable Gas.
- B. The identification number is required for Table 1 materials and when only one hazmat is present.
- D. Class 2.1 Flammable Gas is a Table 1 material and requires placarding for any quantity.
Table 1 Placarding
Certain highly hazardous materials (Table 1) require placarding on a vehicle regardless of the quantity being transported.
- Includes explosives, poison gas, dangerous when wet, and radioactive materials.
- Also includes Division 2.1 (Flammable Gas) and Division 2.3 (Poison Gas).
- Identification numbers are generally required on placards for these materials.
Memory trick: Any quantity of these will make your trip a Table 1 event!
