Which of the following is NOT one of the three common "signal words" for pesticide products?

In the context of pesticide product labeling, "signal words" are used to quickly convey the level of toxicity and potential hazards associated with the product. The three common signal words are "Danger," "Warning," and "Caution." Each of these words indicates a different level of risk to human health and the environment.

"Danger" is used for products that are highly toxic, signaling immediate hazard. "Warning" indicates a moderate level of toxicity, while "Caution" is used for products that are less toxic. These words help consumers and handlers understand the dangers associated with the use of the product and the precautions they should take.

"Hazard," on the other hand, is not a signal word used in this context. While it may describe potential dangers related to various products or situations, it does not serve the specific function of communicating toxicity levels in the same straightforward manner as the other three signal words. Therefore, it is correct to identify "Hazard" as the term that does not belong among the common signal words for pesticide products.
