What signal word indicates high toxicity on pesticide labels?

The word "Danger" on pesticide labels signifies high toxicity. When found on a pesticide product, it indicates that the substance can cause severe harm or even death if inhaled, ingested, or absorbed through the skin. This high-level risk associated with products marked "Danger" necessitates strict personal protective equipment (PPE) and specific handling, storage, and application practices to ensure safety.

In contrast, "Caution" indicates a lower level of toxicity and suggests that the product may pose some risk, while "Warning" indicates a moderate level of toxicity. The term "Safe" implies that the product poses no significant risk, which is not applicable in the context of pesticide labeling. Therefore, "Danger" is a clear indicator that the product requires the utmost care due to its high toxicity potential.
