Mysterious deflagrations: major operation at the synagogue in Stadtschlaining!
On June 29, 2025, there was a major fire department operation in Stadtschlaining, Burgenland, due to a suspected risk of explosion. The fire department was initially alerted because of an alleged roof fire near the synagogue. However, it turned out on site that there was no classic fire, but rather smoke coming from a downpipe, which indicated carbon monoxide (CO) in the sewer system. This reported FireWorld.
The fire department then had to request the Pinkafeld fire department's hazardous materials unit. Measuring devices showed explosive carbon monoxide concentrations in the sewer network. Around 40 people from adjacent buildings, including a hotel and the historic synagogue, were evacuated in collaboration with the Red Cross and police. Evacuation measures were necessary after minor deflagrations and thus the suspicion of a gas leak occurred. Fire department hazardous materials expert Martin Ulreich expressed suspicion that warm temperatures could have caused an underground cable fire that released the toxic gases. MyDistrict added that the heat development may also have increased biodegradable processes in the sewage system.
Emergency measures and all-clear
The fire department initiated extensive ventilation measures in the sewer network and used a special measuring vehicle from Burgenland Energie to locate possible defects in cable and gas lines. The operation was supported by a total of four fire departments with 50 personnel as well as experts from Burgenland Energie, the police and the Red Cross. Despite the serious situation, there were no injuries to report. The all-clear was given by Burgenland Energie at around 3:30 p.m., which meant that the closure of the main square was lifted and residents were allowed to return to their homes.
Carbon monoxide is an odorless and tasteless gas produced by the combustion of carbon-containing materials and poses a major hazard in enclosed spaces. At high concentrations it can cause serious health problems or even death. The gas is lighter than air, making it particularly dangerous when it accumulates in dusty or confined spaces. Symptoms of CO poisoning can include headaches and dizziness. Fire Department Magazine states that special precautions are necessary to protect emergency personnel from these dangers.
