Gas grill explosion on Rettenberg balcony sparks fire and injuries

A gas grill explosion on a balcony in Rettenberg sparked a fire that spread to the building's exterior wall and roof. Two residents suffered minor injuries, likely from smoke inhalation, and received medical treatment. Firefighters quickly arrived to contain the blaze before it caused further damage.

The incident began when the grill ignited unexpectedly, sending flames towards the building. The fire reached the outer wall and parts of the roof, raising concerns of a larger outbreak. Local firefighters from Rettenberg responded promptly and managed to bring the situation under control.

Authorities later identified a defect in the grill as the most probable cause. The explosion follows a wider trend in Germany, where around 200–300 balcony fires occur annually due to grill accidents. Urban areas like Berlin and North Rhine-Westphalia report the highest numbers, with roughly 1,200 such incidents recorded between 2021 and 2025. Early estimates place the property damage at approximately €50,000. The affected residents were treated for suspected smoke inhalation but did not require hospitalisation.

The fire was contained before it could fully engulf the roof, thanks to the quick response of emergency services. Investigations into the exact cause of the grill malfunction are ongoing. Authorities have reminded residents of the risks associated with balcony grilling, especially in densely populated areas.
