What are two "signal words" that may appear on supplier labels?

The correct answer consists of "warning" and "danger," which are widely recognized signal words used on supplier labels to communicate the level of hazard associated with a substance. These words are part of a standardized system designed to quickly convey the urgency and type of hazard present.

“Danger” indicates a more severe hazard, suggesting that the risk of serious injury or death is significant if appropriate precautions are not taken. On the other hand, “warning” signifies a lower level of hazard compared to “danger,” but still indicates that caution should be exercised and that there are potential risks associated with the substance.

Using these signal words helps ensure that individuals handling chemicals or hazardous materials can promptly understand the risks and take necessary safety measures, contributing to a safer work environment. The systematic use of such terminology is crucial in promoting effective communication about hazards across various sectors.
