What is a characteristic of a chemical labeled with "Caution"?

A chemical labeled with "Caution" signifies a moderate level of toxicity. This label serves as a warning that, while the chemical may not be highly toxic like those classified under more severe labels (which might indicate immediate danger), it should still be handled with care to ensure safety. The presence of this label suggests that exposure could lead to health risks, and appropriate precautions should be taken when using the product.

In contrast to the other options, those suggest either an extreme danger or a complete lack of risk, which do not accurately reflect what "Caution" means. A label indicating immediate death represents a much higher toxicity level and generally would fall under a more serious classification like "Danger." Saying a chemical is not toxic at all directly contradicts the implications of the "Caution" label, as it indicates some level of concern regarding safety. Lastly, the idea that it is always safe to use without precautions misrepresents the caution label, which is meant to remind users to take necessary safety measures during handling.
