Gas leak reported near tower complex

To check this alert, Claude Opus 5 (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.

  Final assessment

  Present, 25 of 25. The authority is named outright, "Seattle Fire Department is responding", reinforced by the quoted post from "Seattle Fire Dept. (@SeattleFire)" and by PSE arriving on scene.

  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, 25 of 25. The hazard is stated plainly as "a reported gas leak at a construction site" near the UW Tower, and tracked until it "has been resolved".

  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.

  Final assessment

  Present, 25 of 25. The leak is fixed at "Brooklyn Ave. NE and NE 45th St." near the UW Tower, with the perimeter extended to "15th Ave. NE" and north to "NE 47th St.".

  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.

  Final assessment

  Present, 25 of 25. Readers are told to "please continue to avoid the area until the leak is secured", and "Anyone leaving the UW Tower is asked to move to the south of the building".

  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.

  Final assessment

  Present, 25 of 25. Consequence is conveyed by the evacuation zone, the Tower "currently being evacuated", buildings reopened only "when they are deemed safe", and hours of road closures.

  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.
