What chemical hazard safety signal word indicates that a pesticide is highly toxic?

The term associated with a high level of toxicity for pesticides is represented by the word "danger." This signal word is used to indicate that the substance poses a serious risk to health if ingested, inhaled, or comes into contact with skin. It reflects the potential for acute effects, which could lead to severe illness or death even with a small amount of exposure. The use of "danger" as a signal word serves to clearly communicate the urgency and severity of the chemical hazard, ensuring that individuals handling or applying the pesticide take appropriate precautions and apply stringent safety measures.

The other signal words—"caution" and "warning"—represent lower levels of toxicity; "caution" is typically used for products that are slightly hazardous, while "warning" conveys an intermediate level of risk. "Note" is not a recognized signal word in this context and does not relate to chemical hazard classifications.
