Chlorine gas accident in Beuren: rescue workers on a large scale!
On Wednesday, October 22, 2025, there was a serious incident at the Panorama Therme in Beuren, in the Esslingen district, due to an excessive chlorine concentration in the outdoor pool. The emergency call was made at 4:30 p.m., triggering a major response from rescue workers. Initial information suggests that a technical defect could be the cause of the increased amount of chlorine. The incident prompted an immediate response from emergency services, who treated numerous injured people on site.
A total of twelve people were slightly injured. They mainly complained about respiratory irritation. While some of those affected were treated at the scene, three people had to be taken to hospital to receive further examinations and treatment. Fortunately, the thermal baths did not have to be completely evacuated, and even after extensive measurements by the fire brigade, which revealed no further abnormalities, the pool was able to be reopened at around 6:30 p.m.
Rescue measures and fire brigade operations
The fire department required extensive measures as part of the operation. They arrived with their hazardous goods train to quickly bring the situation under control. The emergency services were quickly on site and were able to immediately look after and care for the injured people. The fire department carried out several measurements to check the air quality and ensure that no harmful substances remained in the area.
The incident raises questions about safety in public swimming pools, particularly regarding the use of chemicals. Such technical defects can have serious effects on the health of bathers, as the chemical accident in Sonthofen recently showed. There, incorrect mixing of cleaning chemicals also caused chlorine gas and required a large-scale rescue operation involving around 40 personnel.
Fortunately, in the incident in Sonthofen there was no greater risk of injuries or health problems for other people, as the fire department also carried out several measurements there and all the results were negative. However, the safety of handling such chemicals is a critical issue that should perhaps be addressed more in the future.
The incidents in Beuren and Sonthofen illustrate how important it is to regularly monitor technical systems in swimming pools and to identify potential dangers at an early stage. It is hoped that lessons will be learned from these events to avoid similar situations in the future. We wish those affected in Beuren a speedy recovery.
