What is considered a "signal word" on a pesticide label?

The term "signal word" on a pesticide label refers to words that provide important information about the level of toxicity associated with the product. Signal words are standardized and represent the degree of the hazard.

In this case, both "Warning" and "Danger" are considered signal words. "Danger" indicates a higher level of toxicity, often associated with products that can cause severe injury or death with even short exposure. "Warning", on the other hand, signifies a moderate level of toxicity. The presence of both of these words on pesticide labels highlights the importance of understanding the potential risks associated with the use of these chemicals.

While "Precaution" is an important part of safety communications on the label, it does not serve the same role as a signal word and does not indicate a specific level of toxicity. Thus, the correct answer encompasses both "Warning" and "Danger," as they both serve the essential function of alerting users to the potential hazards of the pesticide.
