White Over Black placard indicates a corrosive material.

Explanation:
Recognizing placard color patterns helps you quickly identify the hazard class. A white area on top with a black area on the bottom signals corrosive materials (Class 8). This pattern is paired with a pictogram showing a liquid pouring onto a hand and a metal surface, illustrating the kind of damage corrosives can cause: severe burns to skin and corrosion of metals. So this color scheme specifically points to corrosives, not to flammable solids, nonflammable gas, or toxic gas. The other hazard classes use different symbols and color arrangements, which is why they don’t match the white-over-black placard.
