What signal word indicates the highest toxicity level of a pesticide?

The signal word "Danger" indicates the highest toxicity level of a pesticide. This term is used to provide immediate and clear information to users about the potential hazards associated with the product. When a pesticide label features "Danger," it signifies that the product can cause serious harm or even death if misused or improperly handled. This signal word is often associated with highly toxic chemicals that require the user to take significant precautions to ensure safety, including the use of personal protective equipment (PPE) and adherence to specific handling and application guidelines.

In contrast, the other terms—"Caution" and "Warning"—refer to lower levels of toxicity. "Caution" indicates minimal or moderate toxicity, suggesting that the pesticide may still pose health risks, but they are less severe than in products labeled with "Danger." "Warning" offers an intermediate level of risk, indicating a need for careful handling and awareness of potential effects, but still not approaching the extreme hazards signaled by "Danger." "Notice" is not a standard signal word used to indicate toxicity levels in pesticide labeling and is typically associated with non-toxic substances or general information rather than specific health risks. Understanding these distinctions is crucial for assessing the safety and handling requirements for pesticide use.
