Which description corresponds to Alert Tone 1 and how it sounds?

• A. Emergency five-second high-low tone (mayday)
• B. Beep sequence used for routine updates
• C. Priority voice message only
• D. Life hazard 5 second single tone (situations that may cause injury or death)

Answer: (D)

Alert Tone 1 signals a life-hazard situation. The description you’re looking for is a five-second single tone that indicates conditions may cause injury or death, demanding immediate protective action. The single, unvarying tone is designed to cut through noise and grab attention quickly, so responders know to stop and follow urgent safety procedures right away. This contrasts with the other alerts: an emergency five-second high-low tone is used for distress or mayday situations and includes pitch variation; a beep sequence for routine updates is nonurgent and repetitive; a priority voice message conveys information through speech rather than a recognizable tone, so it doesn’t automatically trigger rapid protective actions.
