What is the purpose of a signal word on a pesticide label?

The purpose of a signal word on a pesticide label is to indicate the product's relative acute toxicity to humans and animals. Signal words serve as a quick reference for users to understand the level of danger associated with the pesticide; they are categorized as "Danger," "Warning," or "Caution."

• "Danger" indicates a high level of toxicity, while "Caution" signifies a lower level of toxicity. This information is crucial for safe handling and application of the pesticide, allowing individuals to make informed decisions about protective measures and emergency responses to exposures.

Recognizing the acute toxicity level is essential for protecting both human health and animal welfare, especially for private pesticide applicators who may be in close proximity to the substances they are using. Understanding this key information ensures that applicators are properly equipped to manage risks effectively.
