Which of the following is NOT a signal word found on pesticide labels?

Pesticide labels are carefully regulated, and they use specific signal words to communicate the level of toxicity and the appropriate safety measures to be taken when handling the product. The signal words "Caution," "Warning," and "Danger" are standardized terms that indicate the relative hazards associated with the pesticide.

• "Caution" indicates a low toxicity level.

• "Warning" suggests a moderate toxicity level.

• "Danger" represents high toxicity and the potential for severe harm.

These terms help consumers and professionals understand the risks involved when using the pesticide. "Alert," however, is not one of the recognized signal words within this classification system. This makes it the correct answer, as it does not align with the established terminology used to convey safety information regarding pesticide usage.
