Which of the following signal words indicates lower toxicity?

The signal words on pesticide labels are important indicators of toxicity levels and safety measures necessary when handling these chemicals. "Caution" is the signal word that indicates lower toxicity compared to other terms used on pesticide labels. When "Caution" appears, it signifies that the product poses the least risk to humans and animals, and the handling requirements are generally less stringent than those for products labeled with "Warning" or "Danger."

In contrast, more alarming terms like "Danger" and "Danger/Poison" denote higher toxicity levels that require greater care and often specify more severe health risks associated with the chemical. "Warning" indicates a moderate level of toxicity, meaning that while precautions are necessary, they are not as extreme as those warranted for "Danger" or "Danger/Poison."

Thus, understanding these signal words is crucial for safe pesticide usage and indicates that "Caution" is most appropriate for products associated with lower toxicity levels, ensuring that users can handle them with less risk compared to those labeled with more severe warnings.
