What does the signal word "caution" represent in terms of toxicity?

The signal word "caution" is an indication used on pesticide labeling to communicate the level of toxicity associated with the product. Specifically, it corresponds to Toxicity Category III and IV, which are classified as low toxicity. When a pesticide product bears the signal word "caution," it typically means that, while precautions should still be followed during its use, the inherent toxicity level is not high and is generally considered less hazardous to humans and the environment compared to products labeled as "warning" or "danger."

This categorization is part of a standardized system established by the EPA (Environmental Protection Agency) to help users understand the potential risks associated with pesticide use. Products labeled with "caution" are usually safer to handle and pose fewer acute health risks, provided that users adhere to the prescribed safety measures.

This understanding of the signal word "caution" is crucial for pesticide dealers and users, as it guides them in making informed decisions regarding the safety and handling of different pesticide products based on their toxicity levels.
