What do "signal words" on pesticide labels indicate?

Signal words on pesticide labels are important indicators of the level of toxicity of the product. These words are standardized terms used to provide quick, understandable information about the potential hazards associated with the pesticide. For instance, commonly used signal words include "Danger," "Warning," and "Caution," each reflecting different levels of toxicity. A label that states "Danger" suggests that the pesticide is highly toxic and poses a significant risk to humans and the environment, whereas "Caution" indicates lower toxicity. This system helps users quickly assess the relative danger of handling or applying the pesticide, making it crucial for safety in use.
