Emergency Response at a National Landmark

A localized fire at the renowned Cailler chocolate factory in Broc, situated within the canton of Fribourg, led to a swift emergency evacuation on the morning of April 3, 2026. The incident began at approximately 10:30 am when an automatic alarm system was triggered within the facility's production sector. Security personnel quickly identified a specific source of fire originating from a piece of industrial machinery, prompting an immediate safety protocol to protect both staff and the high volume of holiday tourists on site.

Precautionary Measures for Holiday Visitors

As a direct safety precaution, authorities ordered the evacuation of roughly 150 visitors who were touring the adjacent Maison Cailler building at the time of the alarm. The Fribourg cantonal police confirmed that the evacuation was conducted smoothly and that no individuals sustained injuries during the process. While the fire was largely isolated from public areas, the density of visitors on Good Friday necessitated a total clearance of the visitor center until the scene was declared secure by fire officials.

Containment and Technical Investigation

The local fire brigade arrived on the scene rapidly, successfully bringing the flames under control before the fire could spread to surrounding equipment or structural components of the factory. Initial investigations conducted by the police suggest that the fire was likely caused by a technical malfunction within the production line rather than external factors or human error. Despite the lack of active fire damage to the rest of the facility, the mechanical failure resulted in a temporary halt to production in the affected area.
