What is a common signal word on pesticide labels indicating high toxicity?

The term "Danger" on pesticide labels is a clear signal word indicating high toxicity. In the labeling system established by the Environmental Protection Agency (EPA), signal words serve as a way to communicate the level of acute toxicity of the pesticide to users. "Danger" suggests that the product can cause severe injury or death if ingested, inhaled, or absorbed through the skin. It typically also indicates that there are specific and stringent safety measures that must be taken when handling the pesticide.

In contrast, "Caution" denotes low toxicity, suggesting that the product may cause mild irritation but is less dangerous. "Warning" indicates a moderate level of toxicity, which may pose more risk than a product labeled with "Caution," but less than one labeled with "Danger." "Non-toxic," while not a signal word used in this context, implies that the product does not pose any health risk. Understanding these labels is critical for safe handling and use of pesticides to protect both human health and the environment.
