Which of the following signal words indicates a pesticide is highly toxic?

1. Caution

2. Danger

3. Warning

4. Notice

The correct answer is: Danger

The signal word "Danger" indicates that a pesticide is highly toxic. In the context of pesticide labeling, signal words are critical because they immediately inform users of the level of toxicity associated with a product. "Danger" is used for products that pose a significant risk if ingested, inhaled, or absorbed through the skin, highlighting the need for stringent safety measures when handling such substances. The other terms on the list reflect lower levels of toxicity. "Caution" signifies that a pesticide has a relatively low level of toxicity, while "Warning" indicates a moderate level. "Notice" is not a recognized signal word in the context of pesticide labeling, so it does not convey any toxicity information. Understanding these signal words is essential for safe handling, application, and emergency responses when dealing with pesticides.
