What signal word must be on the label for pesticides classified as "Relatively non-toxic"?

The correct signal word for pesticides classified as "Relatively non-toxic" is "Caution!" This signal word is used to indicate that the product poses a lower risk to health and safety compared to those labeled with "Warning" or "Danger." The use of "Caution!" helps communicate to users that while the pesticide may still have some potential hazards, it is generally considered safe to use with standard precautions.

This classification is crucial for both regulatory compliance and consumer safety, as it helps inform users about the level of risk associated with handling and applying the pesticide. Understanding these classifications is key for anyone involved in structural pest control, as it ensures safe application practices and adherence to regulatory standards.
