What does a signal word indicate?

• A. The relative acute toxicity of the product to humans
• B. The environmental persistence
• C. The storage temperature
• D. The pest kill rate

Answer: (A)

The signal word on a pesticide label communicates the relative level of acute toxicity to humans. It’s a quick guide to how hazardous the product could be in short-term exposure, guiding you on what kind of protective equipment and handling precautions to use. It does not tell you how long the chemical will persist in the environment, nor does it specify the storage temperature or how effective the product is at killing pests. Those factors are described elsewhere on the label. So the signal word’s purpose is to convey human acute toxicity risk, not environmental persistence, storage conditions, or efficacy.
