hazmat campus emergency notice — 4600 block of Union Bay Place NE

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, unanimously at 25 of 25. The post names "Seattle Fire Department officials are responding" and republishes signed posts from "Seattle Fire Dept. (@SeattleFire)", so the issuing authority is unmistakable.

  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 with no dissent. The threat is named exactly as a "confirmed hydrofluoric acid spill in a lab facility", one of the most chemically specific hazard statements in the set.

  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, 25 of 25. The message pins the spill to "the Bowman Building" on the "4600 block of Union Bay Place NE", with closures "between NE 45th St. and NE 50th 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.

• Guidancepresent25/25

  Final assessment

  Present, 25 of 25. "Please avoid the area" is an explicit instruction to recipients, reinforced by the road closures listed on Union Bay Place NE.

  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. The message is doubly stamped, "ORIGINAL POST at 6:33 p.m." and "UPDATE at 8:40 p.m.", fixing both the onset and the reopening.

  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, 25 of 25. Concrete harm is reported: the building "has been evacuated and one person was taken to the hospital for minor exposure", with the patient in stable condition.

  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.
