Which signal words are found on a pesticide label, ranked from most toxic to least toxic?

Pesticide labels use specific signal words to communicate the level of toxicity associated with the product. These words are standardized to help users quickly understand the potential risks. "Danger," "Warning," and "Caution" denote different levels of toxicity, ranked from most to least toxic.

"Danger" is the highest level of warning, indicating that the pesticide could pose a significant risk to health or the environment even with minimal exposure. This is typically associated with highly toxic chemicals that may cause severe reactions or even death.

"Warning" indicates a moderate toxicity level, meaning that the pesticide may cause health effects upon exposure but is less acutely hazardous than those categorized under "Danger." Users still need to exercise caution when handling these products.

"Caution" signifies the lowest level of toxicity used on pesticide labels. Products with this signal word are less likely to cause serious harm but may still pose some risks if not handled correctly.

Understanding this ranking is vital for safe handling and application of pesticides, as it informs users about the necessary precautions to take depending on the toxicity of the product they are dealing with.
