Report
The Schweisweiler and Winnweiler fire departments, as well as several units from the Nordpfälzer Land municipal association, were alerted during the night from Wednesday to Thursday to a fire alarm that had been triggered in the Mühlberg Tunnel near Imsweiler. The first responders inspected the area around the activated detector but were unable to identify the cause. It turned out that the detector’s maintenance indicator was lit, and the activation was likely due to a technical malfunction.
The Rockenhausen Fire Department Operations Center (FEZ) then contacted the tunnel’s control center. The control center dispatched a technician, who drove to the scene and reset the alarm. Only the Imsweiler Fire Department remained on site until the technician arrived; all other units were able to end their response early.
