Fire in underground car park: Two cars in flames, residents safe!
Early on Sunday morning, October 19th, 2025, the Vienna fire department was called to a fire in an underground car park on Hödlgasse. Two vehicles were already ablaze when the fire department arrived. The thick smoke development not only alerted the smoke detectors, but also alerted several residents. Fortunately, there were no injuries in this incident and the apartments above the garage remained smoke-free. An evacuation of the residents was therefore not necessary. Some of them followed the firefighting work from a safe distance.
The challenge for the emergency services was enormous. Several respiratory protection teams were dispatched to fight the flames with targeted extinguishing lines. In particular, removing smoke from the underground car park proved to be extremely time-consuming. After hours of painstaking work, the garage was finally completely smoke-free at 7:30 a.m. The cause of the fire is currently being determined, which is of great importance given the current sources of danger in underground car parks.
Fire protection in underground car parks
Underground car parks pose many security challenges. Tight spatial conditions and the multitude of potential dangers make them a particularly risky area. According to experts, as mentioned in a report on CWS, motor vehicles contain many highly flammable materials. Combustion engines in particular, which contain large amounts of fuels such as gasoline or diesel, make them susceptible to fires.
The growing electromobility represents an additional risk. Lithium-ion batteries pose a specific potential risk that is difficult to control. In the event of a fire, the phenomenon of thermal runaway can occur, which is difficult to extinguish and can result in unpredictable fire progression. This is compounded by the need for more and more underground car parks to be equipped with electric vehicle charging stations, leading to increased electrification and making electricity a common cause of fires. The BVI magazine also offers details on these challenges, which points out the need for a comprehensive fire protection concept.
The events in Hödlgasse are a clear indication of how important well-thought-out fire protection is in such facilities. Proactive planning can help significantly reduce risk and be responsible for preventing similar incidents in the future. Dealing with fire protection measures in underground car parks should therefore not only be viewed as a compulsory exercise, but as an indispensable part of building management. With the increasing use of electric vehicles, it will be essential to develop and implement innovative safety solutions.
