Pesticide labels should include which of the following signal words?

The correct choice highlights the essential signal words that indicate the level of toxicity and hazard associated with a pesticide. The combination of "Danger," "Warning," and "Caution" provides clear categories that help users understand the risk associated with the product.

"Danger" typically signifies that the pesticide can cause severe injury or death if ingested or improperly handled. "Warning" is used for products that may cause moderate hazards, while "Caution" indicates lower toxicity risk but still requires handling precautions. This system of categorization is vital for ensuring safety and guiding users in the appropriate handling and application of pesticides, thereby protecting human health and the environment.

The other choices include words that do not conform to the standardized classifications set by regulatory agencies, which can lead to confusion regarding the severity of the hazard. It is crucial for pesticide labels to adhere to these specified terms to ensure clarity and safety for consumers and applicators alike.
