What are the signal words used on pesticide labels to indicate toxicity?

The signal words used on pesticide labels to indicate toxicity are specifically designed to communicate the potential danger of the product to users. The correct answer includes "Danger-poison," "Danger," "Warning," and "Caution."

These terms have a defined meaning in the context of pesticide safety. "Danger-poison" indicates products that are highly toxic and that even a small amount can cause severe harm or fatality. "Danger" is used for products that are very toxic but might not have the same immediate fatality risk as those labeled "Danger-poison." "Warning" indicates moderate toxicity, suggesting that while the product can cause harm, it typically requires a larger quantity or prolonged exposure to do so. Finally, "Caution" is assigned to products that are considered relatively low in toxicity and pose lesser risks when used as directed.

This system of signal words is standardized to ensure that users can quickly assess the level of risk associated with a pesticide, allowing for more informed decisions regarding safety protocols and handling procedures. The other options presented do not represent established terminology used in pesticide labeling and lack the specificity required for indicating toxicity levels in products.
