Four hospitalized after shisha session triggers carbon monoxide poisoning in Vienna

Four men in Vienna were rushed to hospital after suffering carbon monoxide poisoning while smoking shisha. The incident occurred early Friday morning, with responders detecting dangerously high levels of the gas in their apartment.

The group, aged between 30 and 36, began feeling dizzy and developed severe headaches while using a shisha pipe. Around 4:30 a.m., they called emergency services for help.

Upon arrival, the Vienna Fire Brigade confirmed elevated carbon monoxide levels in the flat. Investigators later ruled out the gas heating system as the source, as it was found to be in proper working order. Authorities believe the poisoning stemmed directly from the shisha smoking session.

This case follows a pattern of similar incidents in the city. Over the past five years, around 25 shisha bars and venues have been inspected by authorities like the MA 37 and fire services due to suspected carbon monoxide poisonings. Roughly half of these locations faced temporary or permanent closures, with notable cases in 2022 affecting multiple people in the Favoriten and Brigittenau districts.

All four men received hospital treatment after the poisoning. The incident highlights ongoing risks linked to shisha use in poorly ventilated spaces. Vienna's emergency services continue to monitor such cases closely.
