How the first alert is built
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.
Safety Bulletin: Mercury Update Following up on the Safety Bulletin sent on November 15 (https://lehigh.apparmor.com/Notifications/CAP/?id=131568&t=219351347), this communication provides information regarding the mercury discovered in Iacocca Hall. Since the discovery, the university has been consulting with a team of specialists to perform remediation and testing, and will continue to follow all provided guidance and recommended protocols. The health and safety of our Lehigh community members remain our top priority throughout this process. Over the last few days, we have received additional results from the swab testing of surfaces in labs in Iacocca C Wing. The results of the swab testing indicate a presence of mercury that is above OSHA limits. These spaces have been closed since the initial discovery of the mercury. The areas have been deep-cleaned by a team of remediation specialists. The cleaning was completed and additional swab testing was conducted on Tuesday. Additional labs near the original location where mercury was discovered will also undergo swab and air quality testing. As shared previously, air quality tests performed in the C Wing indicated levels below OSHA and NIOSH requirements. To accommodate the cleaning and retesting process, the areas that have been closed in Iacocca Hall's C Wing will remain closed until remediation is completed and further testing indicates that the area is safe. Please continue to observe all directional signage and remain out of areas marked closed. The primary route of mercury exposure is inhalation. Virtually no elemental mercury is absorbed through the skin or gastrointestinal tract. The lab spaces affected by mercury are all under negative pressure and well ventilated by building HVAC and exhaust hoods (preventing air in the affected areas from circulating). Air quality test results have consistently shown levels below OSHA and NIOSH requirements. Therefore, individuals who have accessed the C wing are considered at minimal to low risk of exposure and work in all rooms other than those that are closed is safe. To address questions from the community, a page will be published on the university website containing FAQs. This page will go live soon and be updated as remediation and testing continues. Thank you for your continued patience as we work to support the safety of our community. Jason Schiffer AVP, Campus Safety

Final assessment
Present, 25 of 25. It is signed 'Jason Schiffer, AVP, Campus Safety' and written throughout in the university's voice about its own remediation work.
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. Mercury contamination is named plainly, 'the mercury discovered in Iacocca Hall', and tracked through swab and air quality testing.
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 affected spaces are specified as labs in Iacocca Hall's C Wing, plus additional labs near the original discovery point.
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. Readers are told to 'continue to observe all directional signage and remain out of areas marked closed' while closures stay in force.
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.

Impactpresent25/25
Final assessment
Present, 25 of 25. Severity is quantified: swab results show mercury 'above OSHA limits', inhalation is the primary exposure route, and others are at 'minimal to low risk of exposure'.
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.
