Which description matches a Class 2 placard?

• A. Flammable Gas
• B. Non-flammable nontoxic Gas
• C. Toxic Gas
• D. Corrosive Gas

Answer: (A)

Gases are grouped into Class 2 for transport hazards, and the placard text communicates the primary danger you should be ready for. “Flammable Gas” directly signals that the substance can ignite easily, which is the most common and urgent hazard for many gases. That’s why this description best matches a Class 2 placard—the flame symbol and text warn responders to expect flammability and take ignition-control precautions.

The other options point to different gas-related hazards or misfit labels. A non-flammable, non-toxic gas describes a different subcategory of gas hazard, a toxic gas describes another hazard within Class 2, and a label like “Corrosive Gas” isn’t a standard Class 2 description.
