What role do signal words play in pesticide labeling?

Signal words are crucial components of pesticide labeling as they communicate the level of hazard associated with the product. These words, typically categorized as "Caution," "Warning," or "Danger," provide immediate information to users about the potential risks of using the pesticide. Understanding these signal words helps users gauge the precautions they need to take to ensure safety when handling the product. For instance, a label that indicates “Danger” suggests a higher toxicity level, necessitating more stringent safety measures compared to a product labeled “Caution.”

This emphasis on hazard communication is vital for ensuring the safety of users, bystanders, and the environment, allowing for informed decision-making regarding the application and handling of pesticides. In contrast, other aspects of the label—such as identifying the manufacturer, indicating the product's shelf life, or summarizing its ingredients—do not provide specific information about the potential dangers associated with the product's use.
