Over Memorial Day weekend 2024, the University of Alaska Anchorage's Incident Management Team responded to the potential for an ammonia leak tied to the ice-plant refrigeration system at the AVIS Alaska Sports Complex. As maintenance crews worked on remediation, UAA evacuated and closed three buildings (the Sports Complex, Student Union, and General Support Services / Enrollment Services) plus two sections of the campus walkway known as the Spine. The buildings and Spine reopened May 29 after officials determined there was no additional leak risk.

UAA’s Incident Management Team (IMT) is reopened the Avis Alaska Sports Complex (AASC), Student Union, General Support Services and Enrollment Services, and the Spine leading in and out of those buildings on Wednesday, May 29, for regular hours of operation. On Friday, May 25, IMT identified the potential for an ammonia leak within the Ice Plant system and subsequently began an active response to ensure the safety of our campus community and U-MED neighbors. Working diligently with local agencies and the Anchorage Fire Department throughout the weekend, IMT successfully averted the potential for an ammonia leak. We are confident there is no longer a health or safety concern for our Anchorage campus or surrounding community. The safety and well-being of our students, faculty and staff, as well as our U-MED and Anchorage communities, are of utmost importance to the university and IMT. To read IMT’s May 25 update, please visit Green & Gold News. If you have any additional questions or concerns contact John Huffman, interim director of UAA Environmental Health & Safety/Risk Management Support, at 907-310-2917. Sincerely, UAA Incident Management Team

Context

Background

The AVIS Alaska Sports Complex at UAA houses an ice rink whose refrigeration plant uses ammonia, a hazard that can force evacuations if it leaks. According to Alaska's News Source, UAA's Incident Management Team responded to the potential for an ammonia leak and, as crews isolated and remediated the plant, became concerned about the potential for another leak. The Northern Light, UAA's student paper, published a timeline showing the closures spanned the AVIS Alaska Sports Complex, the Student Union, General Support Services, Enrollment Services and two sections of the Spine, the campus's iconic indoor walkway. UAA stated it had not identified public-health risks and the Anchorage Fire Department reported no critical concerns. An official UAA IMT update and a May 29 Green and Gold communication confirmed there was no additional leak risk and reopened the buildings and Spine for regular hours. The verbatim text of UAA's notifications was not published, so the alerts here are reconstructed and marked unconfirmed.
Analysis

Key Findings

An ice-rink ammonia refrigeration system, not a classroom hazard, drove a multi-building closure spanning athletics, the student union and enrollment services
Because the closures linked to the connecting Spine walkway, the hazard effectively cut through the physical center of campus
UAA repeatedly stressed no identified public-health risk while keeping buildings closed for days over a holiday weekend, balancing reassurance and caution
No verbatim UAA notification text was published, so the alert sequence is reconstructed and flagged unconfirmed
Outcome
No injuries and no identified public-health risk; the Anchorage Fire Department reported no critical concerns. UAA reopened the AVIS Alaska Sports Complex, Student Union, General Support Services, Enrollment Services and the Spine on Wednesday, May 29, 2024, for regular hours.
