What is the purpose of a herbicide's "signal word"?

The purpose of a herbicide's "signal word" is to indicate the level of toxicity of the product. Signal words are part of the labeling on pesticide products, including herbicides, and are a critical component of safety information. They are categorized based on the severity of the hazard the product poses if misused. Common signal words include "Caution," "Warning," and "Danger," with each term representing a different level of toxicity. This system helps users quickly identify the risk associated with handling and applying the herbicide, ensuring that proper safety measures can be taken, thereby promoting the safe and responsible use of these chemicals. Understanding the signal word is essential for anyone involved in herbicide application, as it provides a straightforward way to assess potential dangers during use.
