# Leeuwarden Ice Rink Closes Again Following Ammonia Leak The Elfstedenhal facility remains shut until Monday after recurring technical cooling system failures. - **Source:** [NOS Nieuws](https://nos.nl) - **Published:** 2026-11-07 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/52523022-094e-4876-ae62-87e6cbc13360 ## Recurring Technical Failure The Elfstedenhal in Leeuwarden has been evacuated for the second time this week due to an ammonia leak. Ammonia is utilized within the facility's technical room to facilitate the cooling of motors. This recurring malfunction has forced management to keep the ice rink closed to the public until at least next Monday. ## Previous Evacuation Incident During the initial incident on Tuesday, approximately 400 people were present inside the building when the leak occurred. Director Klaas Siderius described the severity of the first event to the Leeuwarder Courant, noting that the substance was spraying out aggressively. That event triggered an immediate and mandatory evacuation of the entire facility. ## Safety Protocol Activation The facility operates under strict safety protocols designed to manage hazardous chemical leaks. Upon detection of ammonia, an automated alarm system alerts the technical department immediately. Staff members are presented with a red screen indicator, which triggers the standard operating procedure to clear the building of all visitors and personnel without delay. ## Current Leak Severity Director Siderius confirmed that the most recent leak involved only a small quantity of ammonia compared to the earlier incident. He emphasized that no individuals were placed in danger during this second occurrence. The leak was identified promptly by the monitoring systems, allowing for a controlled and rapid response by the onsite team. ## Cooling System Infrastructure Ammonia serves as a critical refrigerant in large-scale industrial cooling systems, such as those required for maintaining ice rinks. While efficient for thermal management, the chemical requires robust containment infrastructure. The repeated failures at the Elfstedenhal suggest potential underlying issues within the facility's mechanical components or the integrity of the cooling pipes. ## Operational Impact Assessment The decision to remain closed until Monday indicates that maintenance teams require significant time to diagnose and permanently resolve the cooling system fault. Such closures disrupt scheduled training sessions and public skating activities. Management must now balance the need for thorough technical repairs with the pressure to resume normal facility operations quickly. ## Risk Management Standards Facilities handling hazardous refrigerants like ammonia must adhere to stringent safety regulations to protect the public. The reliance on automated alarm systems and immediate evacuation protocols demonstrates a prioritized approach to risk mitigation. However, the recurrence of the leak highlights the challenges in maintaining aging or complex mechanical infrastructure under pressure. ## Future Facility Outlook Moving forward, the Elfstedenhal will likely face scrutiny regarding the long-term reliability of its cooling infrastructure. Ensuring the safety of 400 visitors remains the primary objective for the administration. Future reopening will depend on successful technical inspections and the verified stability of the cooling system to prevent any further chemical exposure incidents. ## Sources covering this story - https://nos.nl/l/2638509 — --- _Summary written by Brifing from the original reporting.
