What do signal words on pesticide safety indicate?

• A. Pesticide color
• B. Water solubility
• C. Recommended storage temperature
• D. Relative toxicity of a pesticide

Answer: (D)

Signal words on pesticide labels communicate the level of acute toxicity and hazard to people and animals from short-term exposure. They guide you on how careful you need to be, what personal protective equipment to use, and what emergency steps to take if exposure occurs. That’s why the correct answer is about relative toxicity. The words don’t tell you things like product color, how soluble the chemical is in water, or the exact storage temperature—that information comes from other parts of the label or separate data, not from the signal word.
