Placard color yellow indicates which hazard?

Explanation:
Color-coded placards use background color to signal the general type of hazard. The yellow placard is reserved for oxidizers and reactive substances—materials that can feed a fire or react violently under certain conditions. So a yellow placard points to an oxidizer or reactive hazard. It’s not indicating a health hazard (blue), a flammable hazard (red), or explosives (orange). When you see yellow, think oxidizer or reactive, and check the specific symbol on the placard for the exact classification and required handling precautions.
