Students, Faculty, and Staff: The University will TEST the Alert Carolina Emergency Notification System on Tuesday, Feb. 17, 2026, between 11 a.m. and 1 p.m. We test Alert Carolina regularly throughout the year to make sure the equipment and notification processes work as planned. During this sirens test, NO ACTION is required. During the test, anyone outside on or near campus will likely hear the Outdoor Emergency Sirens. These sirens are not designed to be heard inside a building or vehicle. The sirens will sound an alert tone along with a brief prerecorded voice message. The sirens sound only for a major emergency or an immediate safety or health threat, such as: - An armed and dangerous person on or near campus - A major fire or hazardous material incident outdoors - A tornado warning for the Chapel Hill-Carrboro area issued by the National Weather Service - A different emergency, as determined by Campus Safety The University will also send text messages to cellphone users who registered their numbers in the online Alert Carolina contact information page available through the Onyen services website. The University will post safety-

How the first alert is built

To check this alert, Claude (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

    Present: Source in residual alert.

    Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

  • Hazardpresent25/25

    Final assessment

    Present: Hazard in residual alert.

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

  • Locationpresent25/25

    Final assessment

    Present: Location in residual alert.

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

  • Guidancepresent25/25

    Final assessment

    Present: Guidance in residual alert.

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

  • Timepresent25/25

    Final assessment

    Present: Time in residual alert.

    When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

  • Impactpresent25/25

    Final assessment

    Present: Impact in residual alert.

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
