Safety Bulletin: Mercury Remediation Update Following up on the Safety Bulletin from last week (https://lehigh.apparmor.com/Notifications/CAP/?id=131299&t=218118513), this communication provides information regarding mercury that was discovered in Iacocca Hall. Work in the building has concluded and test results obtained to date indicate that the risk of exposure is low. Certain rooms on floors 1 through 3 of the C Wing remain closed as we await the final analysis of swab testing. Please continue to observe all directional signage and keep out of areas marked closed. Remediation and Testing Results All mercury that is or was present has been contained and removed. Air quality testing results indicated that levels in the air were below OSHA and NIOSH requirements and considered safe. The Environmental Health & Safety Department (EH&S) is awaiting complete results of swab testing. At this time, test results indicate there are no risks of mercury exposure in other areas of the building. Staff involved in the initial discovery and removal attempt were considered to have a risk of acute exposure. Those staff members were provided with specific resources and information regarding mercury exposure. They were tested and results indicated minimal exposure. Based on OSHA and NIOSH standards, no other individuals were considered to be at-risk for either acute or chronic exposure. No further testing of individuals was deemed necessary based on air quality test results. Individuals who were present in the C Wing before the mercury was detected are considered to be at low risk and testing is not recommended. Thank you for your patience as we await the remaining swab results, work to support the safety of our community, and reopen Iacocca Hall. We will continue to monitor and evaluate the situation and will communicate updates as we receive more information and results. Jason Schiffer AVP, Campus Safety

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.

    Final assessment

    Present, 25 of 25. The bulletin is signed by the Associate Vice President for Campus Safety and names the Environmental Health and Safety Department as the testing body.

    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.

    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. Iacocca Hall is named, narrowed to 'certain rooms on floors 1 through 3 of the C Wing' that remain closed.

    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 asked to 'continue to observe all directional signage and keep out of areas marked closed'.

    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 addressed throughout: 'the risk of exposure is low', air levels below OSHA and NIOSH requirements, and staff at 'risk of acute 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.
