Which signal word indicates a product is slightly toxic to relatively nontoxic?

The signal word "Caution" is used to indicate that a product is slightly toxic or relatively nontoxic. This designation is part of a hazard categorization system that helps communicate the relative toxicity of products to users.

When a product carries the label "Caution," it implies that while there is some level of risk associated with its use, it does not pose serious health threats under normal conditions of use. This classification is important for ensuring that users take appropriate precautions without overreacting to the potential hazards.

In contrast, "Warning" signifies a higher level of toxicity, indicating that a product may pose more significant health risks. "Danger" is reserved for products that are highly toxic or pose an immediate threat to health or life, thus requiring strict adherence to safety protocols. The term "Advisory" is not a standard signal word in this classification system and does not convey specific toxicity levels.

Understanding these classifications helps users make informed decisions about handling and applying pest control products safely.
