If a label shows 'Warning', what can be inferred about its hazard relative to 'Caution' and 'Danger'?

• A. More hazardous than Caution but less than Danger
• B. More hazardous than Danger but less than Caution
• C. More hazardous than both Caution and Danger
• D. Less hazardous than both Caution and Danger

Answer: (A)

Hazard levels on labels are ranked by how serious the risks are. Danger is the highest level, signaling an imminent hazard. Caution is the lowest level, warning of minor hazards. A Warning sits between them, indicating a hazard that's more serious than Caution but not as extreme as Danger. So when you see “Warning,” you know there are real risks and you should follow the safety precautions, but it isn’t at the peak level of danger. If it were more hazardous than Danger, that would break the hierarchy; if it were less hazardous than Caution, it would imply an even milder risk than the lowest warning, which isn’t the case.
