Deadly Flashover Suspected in Swiss Resort Blaze as Death Toll Climbs to 47
Crans-Montana, Switzerland — Swiss authorities reported that the death toll from a catastrophic fire at a popular bar in the Alpine ski resort of Crans-Montana has increased to 47, with investigators pointing to a possible flashover as the trigger for the intense explosion and blaze that devastated the venue during New Year’s celebrations.
The incident occurred at Le Constellation bar in Valais canton, where hundreds of revelers had gathered to welcome the new year. The crowded establishment, capable of hosting several hundred patrons, was packed when the fire erupted early on New Year’s Day, leading to rapid and devastating spread.
Valais canton attorney general Béatrice Pilloud stated during a press conference that multiple hypotheses are under review, but the primary focus is on a flashover—a sudden and near-simultaneous ignition of all flammable materials in an enclosed space. “The main theory we’re prioritising is a flashover that provoked a rapid explosion,” Pilloud said, noting that witnesses have been interviewed and recovered mobile phones will be examined. She emphasized that the precise chain of events is still unclear, with the probe ongoing.

According to the US-based National Fire Protection Association (NFPA), flashover happens when accumulating hot gases elevate room temperatures to a point where every combustible item ignites at once. Steve Kerber, Vice President and Executive Director of the Fire Safety Research Institute, explained to US broadcaster CNN: “Flashover is when you no longer have objects in the room on fire. The room is on fire.”
Officials have firmly ruled out any terrorist involvement. Emergency responders worked through the night, deploying ambulances and helicopters to transport the injured and secure the area.
No details on victim identities have been released yet. Further updates are anticipated as forensic analysis continues at the site.
