The Risk of an Ammonia Leak From an Ice Plant Closed Three Buildings and the Spine

AKhazmatemergency notificationmedium confidence

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.

INITIAL ALERTEmail

UAA Incident Management Team: Due to the potential for an ammonia leak from the ice plant near the AVIS Alaska Sports Complex, the Sports Complex, Student Union, General Support Services and Enrollment Services, and connecting sections of the Spine are closed until further notice. Avoid these areas.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Reconstructed from reporting: a potential ammonia leak in the AVIS Alaska Sports Complex ice-plant system was reported to UAA's Incident Management Team on May 24, 2024, triggering staged building closures.
Ammonia is a common industrial refrigerant for ice rinks; a leak risk in the plant explains why an athletics building drove closures of adjacent academic and services buildings.
UPDATEEmail

UAA IMT Update: Maintenance crews are isolating the ice plant and completing remediation. Building closures remain in effect for the AVIS Alaska Sports Complex, Student Union, General Support Services and Enrollment Services, and the Spine. No public health risk has been identified.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Reconstructed from the May 27, 2024 reporting: crews were isolating and remediating when maintenance workers became concerned over the potential for another leak, extending the closures over the holiday weekend.
UAA's IMT stated it had not identified public-health risks and the Anchorage Fire Department had no critical concerns, language meant to reassure without lifting the closures.

UAA IMT Update: There is no additional risk of an ammonia leak. The AVIS Alaska Sports Complex, Student Union, General Support Services and Enrollment Services, and the Spine have reopened for regular hours of operation.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Reconstructed all-clear: a May 29, 2024 communication in UAA's Green and Gold indicated no additional risk of ammonia leaks, and all closed buildings plus the Spine reopened for regular hours.
The all-clear explicitly reopens the named buildings and the Spine, distinguishing it from the earlier 'closed until further notice' messages.
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.
