A driver is transporting 2,500 pounds of UN1075, Liquefied Petroleum Gas (LPG), which is a Division 2.1 (Flammable Gas). The LPG is contained in multiple non-bulk cylinders. Which of the following statements regarding the placarding of this vehicle is correct?
- ANo placards are required because the material is in non-bulk packaging.
- BBoth 'FLAMMABLE GAS' and 'DANGEROUS' placards are required.
- COnly a 'DANGEROUS' placard is required on two sides.
- DOnly a 'FLAMMABLE GAS' placard is required on all four sides.
Show answer & explanationAnswer & explanation
Correct answer: D. Only a 'FLAMMABLE GAS' placard is required on all four sides.
Division 2.1 (Flammable Gas) is a Table 2 material. However, even for Table 2 materials, if the aggregate gross weight of all Table 2 materials is 1,001 pounds or more, the vehicle must be placarded with the specific placard for each material. Since 2,500 pounds of Flammable Gas are being transported, a 'FLAMMABLE GAS' placard is required on all four sides. The 'DANGEROUS' placard is used when 1,001 pounds or more of two or more different Table 2 materials are transported, and no Table 1 material is present.
Why the other options are wrong
- A. This is incorrect. While bulk packaging has specific placarding rules, non-bulk packaging also requires placarding if the aggregate gross weight of Table 2 materials (like Division 2.1) exceeds 1,001 pounds, which it does here (2,500 lbs).
- B. This is incorrect. A 'DANGEROUS' placard is used when a vehicle contains 1,001 pounds or more of two or more different Table 2 materials, and no Table 1 materials are present. In this scenario, only one type of Table 2 material is present, so the specific 'FLAMMABLE GAS' placard is used.
- C. This is incorrect. The 'DANGEROUS' placard is not applicable here, and placards must be displayed on all four sides of the vehicle, not just two.
Placarding for Single Table 2 Materials (Over 1,001 lbs)
When a vehicle transports 1,001 pounds or more of a single type of Table 2 hazardous material (not in bulk packaging and no Table 1 materials present), it must be placarded with the specific placard for that material on all four sides.
- Applies to Table 2 materials (e.g., Flammable Gas, Flammable Liquid).
- Threshold: 1,001 lbs or more aggregate gross weight.
- If only one Table 2 material meets the threshold, use its specific placard.
- If two or more Table 2 materials meet the threshold, use 'DANGEROUS' placard (unless specific placards are required).
Memory trick: Table 2 materials need a weight check; over a grand, use the right brand name placard.
