CDL Hazardous Materials Endorsement (HME)Hazardous Materials RegulationsEasy
A driver is transporting a shipment of Division 2.2 (Non-Flammable, Non-Poisonous Gas) in cylinders. The total gross weight of this material is 1,500 pounds. What type of placard is REQUIRED for this shipment?
- ANON-FLAMMABLE GAS placard.
- BFLAMMABLE GAS placard.
- CNo placard is required.
- DDANGEROUS placard.
Show answer & explanationAnswer & explanation
Correct answer: A. NON-FLAMMABLE GAS placard.
Division 2.2 (Non-Flammable, Non-Poisonous Gas) is a Table 2 material. Since the gross weight of this single class of material (1,500 pounds) exceeds the 1,001-pound threshold for Table 2 materials, a specific 'NON-FLAMMABLE GAS' placard is required.
Why the other options are wrong
- B. This material is Non-Flammable Gas, not Flammable Gas (Division 2.1).
- C. 1,500 pounds exceeds the 1,001 pound threshold, so placards are required.
- D. A DANGEROUS placard is used when the aggregate of various Table 2 materials exceeds 1,001 lbs but no single class meets its individual threshold, or when specific placards are not otherwise required. Here, a specific placard is required.
Single Table 2 Material Placarding
If a single hazard class from Table 2 of 49 CFR 172.504(b) is transported in non-bulk packages with a gross weight of 1,001 pounds or more, then the specific placard for that hazard class is required.
- Applies to non-bulk packages.
- Threshold is 1,001 pounds for a single class.
- If threshold met, use the specific placard (e.g., NON-FLAMMABLE GAS).
- Distinguish from 'DANGEROUS' placard use for mixed Table 2 loads.
