What signal word is required on the label for pesticides that are classified as "Highly toxic"?

The signal word required on the label for pesticides that are classified as "Highly toxic" is "Danger!" This designation indicates that the pesticide poses a significant risk of harm to individuals who may be exposed to it, emphasizing the need for extreme caution when handling these substances. The use of "Danger!" signals that the product may cause severe injury or even death if mishandled, reinforcing the importance of following safety guidelines and protective measures specified on the label.

In contrast, other signal words like "Caution!" and "Warning!" are used for pesticides that, while still hazardous, do not present the same level of acute toxicity or immediate danger as those labeled with "Danger!". Consequently, understanding signal words is crucial for safe pesticide use and helping applicators make informed decisions about handling and applying these chemicals.
