Which type of words indicate the strength of a pesticide?

Signal words are specifically designed to indicate the strength or level of toxicity of a pesticide. These words provide essential information to users about the potential risks associated with the product. Generally, signal words like "Caution," "Warning," and "Danger" convey different levels of hazard; for instance, "Danger" indicates a high level of toxicity while "Caution" suggests lower toxicity. Understanding these terms is crucial for safe handling and application of pesticides.

While warning labels, usage instructions, and hazard symbols play important roles in providing safety information and proper application guidance, they do not specifically convey the strength or toxicity level in the same concise manner as signal words do. This makes signal words a key element in pesticide labeling, ensuring that users are adequately informed about the potential dangers of the product they are handling.
