What do the toxicity signal words "Caution", "Warning", and "Danger" indicate?

The toxicity signal words "Caution", "Warning", and "Danger" are used to indicate the relative toxicity of a pesticide. Each term reflects the level of hazard associated with the substance.

"Caution" indicates that the pesticide is slightly toxic and can pose minimal risk under normal handling and usage conditions. On the other hand, "Warning" signifies a moderate level of toxicity, suggesting more precautions are necessary when handling the product. Finally, "Danger" denotes high toxicity, meaning that the pesticide can be very harmful or fatal to humans and/or animals without proper precautions. These signal words play a crucial role in helping pesticide users understand the risks involved and the necessary safety measures they should take when working with these products.

The other options do not relate to toxicity levels: the cost of the pesticide, storage methods, and expiry dates do not provide information on how toxic a pesticide may be to humans or the environment.
