Eleven-year-old flown by helicopter to Graz after carbon monoxide accident in Vienna

Two other family members treated

In addition to the girl, two other family members were treated at the scene, according to Had. "Zwei Familienmitglieder wurden ebenfalls versorgt, berichtete Had." However, these two people did not need to be taken to a hospital. Had explained: "Diese mussten jedoch nicht in ein Krankenhaus gebracht werden."

Danger from carbon monoxide

According to the emergency services, the accident is related to a gas heating system in the affected apartment. Carbon monoxide is produced by incomplete combustion and is odorless—which is why poisoning is often only noticed once those affected are already showing symptoms such as dizziness, nausea, or loss of consciousness. The incident serves as a reminder of how dangerous defective or poorly maintained gas heaters in living spaces can be.

The exact circumstances that led to the carbon monoxide leak have not yet been conclusively clarified. It is also unclear how the girl is currently doing. The authorities are expected to further investigate the case in order to determine the cause of the incident.
