Which label must appear on a pesticide that identifies the maximum potential hazard to the applicator's health?

1. Warning

2. Caution

3. Note

4. Danger

The correct answer is: Danger

The label that must appear on a pesticide indicating the maximum potential hazard to the applicator's health is "Danger." This label signifies the highest level of toxicity and signals that the product can cause severe injury or death if not handled properly. It is critical for users to take appropriate precautions to avoid exposure, as products labeled with "Danger" typically contain the most hazardous ingredients. In comparison, "Warning" labels indicate a moderate level of toxicity where exposure could lead to significant health risks, but not as immediate or severe as those associated with "Danger." "Caution" labels denote a lower risk level and suggest that safety measures should still be taken, but the potential for severe harm is less than that posed by products labeled "Warning" or "Danger." "Note" is not a label used to classify toxicity levels in pesticides and does not provide relevant safety information regarding health hazards. Understanding these classifications is crucial for ensuring safety during pesticide application and handling, as they guide users in making informed decisions about the protective measures necessary based on the toxicity of the pesticide.
