Impactabsent3/25
Final assessment
Majority 22 of 25 find no stated consequence beyond naming a possible gun. Three reads treat safety-is-most-important wording as implied severity.
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.
