What does a signal word indicate about toxicity?

• A. Toxicity category that decreases in toxicity order
• B. Expiry date
• C. Manufacturer
• D. Price tier

Answer: (A)

Signal words on pesticide labels convey how acutely toxic the product is, guiding you on safe handling and what protective gear to use. They correspond to a toxicity category that goes from higher to lower danger, helping you gauge risk at a glance. In practice, the most dangerous products bear the strongest signal word, and the warning becomes less severe as toxicity decreases. This is why the correct idea is that the signal word reflects a toxicity category arranged in decreasing hazard from most toxic to least. It isn’t about expiry dates, who manufactured it, or price tiers, which are unrelated to how toxic a product is.
