Firefighters in Düsseldorf were called to an Alten- und Pflegeheim in Heerdt after an automatic fire alarm went off at 17:19 on Saturday. Before the first crews arrived, staff called the fire service to report that a rollator was burning in a room on the second floor. The alarm was upgraded and more units were sent. When firefighters reached the scene, they confirmed the report. In a patient room, a rollator caught fire for reasons still unclear. Staff quickly stopped the spread with two fire extinguishers, and moved residents to a safe area before the crews took over. Firefighters then carried out checks and firefighting and extinguished hotspots. The affected floor was briefly ventilated to clear smoke from the area. An ambulance checked one resident and five care staff members who were believed to have inhaled smoke. A resident and one care worker were taken to hospital with minor injuries. After the incident was under control, residents were able to return to their care rooms, according to the fire service.
