Tests aim to familiarize people who work and live in different places with the sirens.
Additionally, it is important to ensure the sirens work properly and educate the public about what action to take when they hear the sirens.
When you hear a siren, you should:
- Tune in to radio stations KOA 850 AM, KBCO 1190 AM, or 97.3 FM
- Turn on local television news channels (2, 4, 7, 9, or 31). Listen for a voice message if you are near a voice-activated siren
- Refrain from calling 911
