QAL Laws & Regulation Practice Exam

Which toxicity category signal word means "caution"?

1. Danger

2. Warning

3. Caution

4. No signal word

The correct answer is: Caution

The signal word "caution" is associated with a toxicity category that indicates a lower level of hazard compared to other signal words. In terms of toxicity classification, it typically reflects substances that may cause mild health effects or are of a less severe nature. This term is used to alert users to take precautions when handling the substance, but it does not convey the level of immediate danger that terms like "danger" or "warning" would signal. In contrast, the other signal words relate to different levels of risk. "Danger" indicates a high level of toxicity and imminent harm, requiring immediate attention and precaution. "Warning" represents a moderate risk but is still more severe than "caution." The absence of a signal word suggests that the substance is considered to pose minimal risk relative to those with signal words. Therefore, "caution" is the correct answer for denoting a relatively safer or less hazardous situation.
