Minnesota Pesticide Applicator Practice Test

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

1. Indicate relative acute toxicity

2. Inform about PPE requirements

3. Indicate toxicity to insects

4. Guide on first aid procedures

The correct answer is: Indicate relative acute toxicity

The signal word on a pesticide label is designed to indicate the relative acute toxicity of the product to humans and animals. It serves as a critical component of label communication, providing users with immediate information about the potential hazards associated with the product. The signal words are categorized as either "caution," "warning," or "danger," with the level of risk increasing from "caution" as the least toxic to "danger" as the most toxic. This enables applicators to assess the product's safety and take appropriate precautions before use. Understanding the signal word assists in ensuring safety practices are properly followed, such as wearing personal protective equipment (PPE), although PPE requirements are more specifically detailed elsewhere on the label.
