• Impactpresent24/25

  Final assessment

  Majority 24/25 codes 1: Impact includes hospital transport after the blow to the mouth, not only the assault label.

  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.
