What signal words are used to alert users to potential hazards?

Signal words are essential for communicating the severity of potential hazards in various environments, particularly in safety and health contexts. The correct answer, which includes the terms "Danger" and "Warning," is rooted in a tiered system of warnings used to convey different levels of threat.

"Danger" is the most severe signal word, indicating that an immediate hazard exists that could result in severe injury or death if not addressed. This word is a clear call to action, underscoring the urgency of the situation.

"Warning," while still indicating potential harm, suggests a lesser degree of threat compared to "Danger." It signals that a hazard exists which may cause injury or death, but may require immediate attention rather than instant reaction.

Together, these terms create an effective hierarchy for users to prioritize their responses to hazards, enhancing safety by aligning the gravity of the message with the appropriate cautionary action.
