  Final assessment

  All 25 agree (1): The address is given as "541 Main St on the University of South Carolina's Columbia campus," with "Main St between Blossom St and Wheat St" closed.

  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.

• Impactpresent25/25

  Final assessment

  All 25 agree (1): Aside from the incident itself, the practical impact is that "Main St between Blossom St and Wheat St is closed."

  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.
