What do signal words on pesticide labels categorize?

Signal words on pesticide labels categorize toxicity levels, which provide essential information about the potential hazards associated with the pesticide. These words help users understand the relative danger of the product if handled improperly or if there is accidental exposure. For instance, signal words such as "Warning," "Caution," and "Danger" indicate increasing levels of toxicity, allowing users to assess the risk associated with using the pesticide effectively.

Understanding toxicity levels ensures that individuals who handle pesticides can take appropriate safety precautions to protect themselves, others, and the environment. This categorization is crucial for making informed decisions regarding usage, including necessary protective equipment, application methods, and emergency response actions in case of accidental exposure.
