What does the signal word on a pesticide label indicate?

The signal word on a pesticide label serves as a quick reference for the toxicity level of the product, alerting users to the potential risks it poses to humans and the environment. The signal word categorizes the pesticide into differing levels of toxicity, indicating whether it is highly toxic, moderately toxic, or slightly toxic. This helps users make informed decisions regarding handling, application methods, and protective measures needed when using the pesticide.

For instance, signal words such as "Danger" are used for products that pose high toxicity risks, while "Warning" indicates moderate risks, and "Caution" signifies lower toxicity. Understanding the signal word is crucial for ensuring safety and compliance with health regulations, emphasizing its importance in pest control operations. This categorization does not pertain to a product’s effectiveness, compatibility with other substances, or its formulation type, making it a specific indicator of toxicity alone.
