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

The two "signal words" that may appear on supplier labels designed to communicate hazards are "Warning" and "Danger." These terms are part of a standardized system that allows individuals to quickly understand the level of risk associated with a product.

"Warning" is used to indicate that a substance poses a moderate hazard, suggesting that caution should be exercised. This word alerts users to the presence of potential risks and encourages them to take necessary precautions. On the other hand, "Danger" signifies a more severe level of hazard, meaning that immediate attention is required to prevent serious injury or adverse effects. Using these signal words effectively conveys the necessary information about the risks presented by hazardous materials, aiding in safety and compliance in various work environments.

The other choices, while they contain terms associated with risk, do not include the standardized "signal words" recognized in safety communication. This reinforces the importance of using the correct terminology to ensure clarity and consistent understanding of hazards.
