How does a signal word relate to pesticide toxicity?

A signal word is a crucial element found on the pesticide label that categorizes the acute toxicity of the pesticide. This word—such as "Danger," "Warning," or "Caution"—provides immediate information about the potential risk associated with the product's use. The specific signal word used can help users understand how hazardous the product may be upon exposure and how strictly safety measures should be followed during its application. For example, a product labeled with "Danger" would indicate a higher level of toxicity compared to one marked with "Caution."

Understanding the signal word is vital for anyone handling pesticides, as it influences decisions related to personal protective equipment (PPE), application techniques, and overall safety protocols on the job. In contrast, the other options all pertain to different aspects of a pesticide product and do not serve the primary purpose of conveying toxicity levels directly.
