WEYBURN - Ammonia was detected in the arena ice plant room at around 12:10 a.m. on Thursday, and the Weyburn Fire Department promptly responded to assist facilities staff with safety procedures. They helped to ensure the room was safely cleared of ammonia and the source was isolated.
The source of the ammonia was identified as a pressure relief valve, which activated as designed to prevent a dangerous pressure buildup within the system.
The incident was determined to have originated in the condenser tower.
Refrigeration contractors arrived on the site shortly after the incident and worked alongside facilities staff until 5 a.m., conducting inspections and trouble-shooting the system to prevent further issues.
Later on Thursday, refrigeration contractors, TSASK, and inspectors were on-site conducting cleanup efforts, reviewing system operations, and inspecting the repairs made to the chiller vessel earlier in the week.
Further updates will be provided as more information becomes available.
The City remains committed to keeping the public informed, and looks forward to welcoming skaters and players back to the arenas as soon as possible.
