Position 4 on a hazard placard relates to which category?

• A. Health (blue)
• B. Flammability (red)
• C. Reactivity (yellow)
• D. Special information (white)

Answer: (D)

Hazard placards use color-coded sections to signal different kinds of danger. Each color corresponds to a category: blue for health, red for flammability, and yellow for reactivity. The white area, which sits in the fourth position, is for special information. That white section can carry symbols like OX for oxidizers or W with a slash for water reactivity, indicating specific handling or compatibility notes. So the fourth position being the white area points to Special information as the category. The other colors map to health, flammability, and reactivity, not to special information.
