A 12-year-old girl collapsed while showering in Vienna-Simmering on Saturday due to carbon monoxide poisoning.

Her parents called for help just before 3 PM, and emergency responders found high levels of CO in the apartment.

The girl was quickly taken to the hospital, as she was close to losing consciousness.

Firefighters conducted checks in the building and surrounding apartments, setting up a ventilation device in the stairwell.

They emphasized the importance of regular maintenance for gas appliances and proper ventilation, especially during hot weather.

It is crucial to keep windows open while showering to prevent dangerous gas buildup.
