Which signal word would most likely accompany a label that states "extremely hazardous by skin contact - rapidly absorbed through the skin"?

The term "Danger" is used on labels to indicate that a substance poses a significant risk of severe injury or adverse effects when encountered. In the context of a label that states "extremely hazardous by skin contact - rapidly absorbed through the skin," the use of "Danger" is appropriate because it conveys the serious nature of the hazard associated with skin exposure to this chemical.

This signal word is primarily reserved for situations where immediate and potentially life-threatening harm could occur, making it critical for safety awareness and the implementation of protective measures. The presence of phrases such as "extremely hazardous" and "rapidly absorbed" highlights the urgency and potential severity of the risk, reinforcing why "Danger" is the most suitable choice for this label.

In contrast to the other options, "Caution" and "Warning" denote lower levels of hazard severity, focusing on risks that may lead to minor or moderate injuries rather than severe consequences. "Hazard" is more generic and not a standardized signal word used in the same impactful way as "Danger." Therefore, "Danger" effectively communicates the highest level of hazard relevant to the situation described.
