Dan Moir, an off-duty firefighter from Calgary, was at a hockey tournament in December 2024, watching his son play when his son suddenly felt unwell. Several other players also started experiencing similar symptoms shortly after. Moir suspected carbon monoxide poisoning due to the symptoms matching those of CO exposure. His suspicions were confirmed when 23 children and two adults, including his son, required treatment at Alberta Children’s Hospital in Calgary.
Moir, along with two other parents, shared their experiences in the Canadian Medical Association Journal (CMAJ) to raise awareness about the risks of CO and nitrogen dioxide exposure in ice arenas. Despite federal recommendations, many ice rinks lack proper safety measures like CO monitors, leading to potentially dangerous CO exposures.
The incident, which occurred in a rural Alberta arena, highlighted the lack of rules regarding CO safety in ice rinks, leaving parents like Jessica Marshall concerned about the safety of their children. The CMAJ article revealed multiple CO poisoning incidents in indoor ice rinks across Canada, emphasizing the need for better safety protocols.
Vittoria Vecchiarelli, from the Canadian Institute of Public Health Inspectors, explained that combustion-engine equipment used in ice rinks can emit high levels of CO and NO2 if not properly maintained. Symptoms of CO exposure include dizziness, headaches, and nausea, with potential long-term effects on health if left untreated.
Dr. Bruce Campana emphasized the importance of preventing CO poisoning in ice rinks due to the serious health risks it poses, especially for athletes exerting themselves on the ice. He highlighted the need for proper safety measures like CO detectors to avoid similar incidents in the future.
