Kart racing disaster in Cologne: 22 injured after poison gas incident!
An exciting weekend at the Kartcenter Cologne in Cologne-Hahnwald took a violent turn on Friday evening. During the first day of racing in the “Cologne Cup”, a popular racing series with qualifying and driver changes, numerous participants and spectators were surprised by health problems. At around 10 p.m., 22 people complained of acute headaches and nausea, which triggered a large-scale operation by the fire department and police.
A suspected defect in the ventilation system is the suspected cause that led to an increase in the carbon monoxide concentration in the indoor go-kart track. According to ksta.de, the fire department found increased carbon dioxide levels during its measurements. After these questionable values were discovered, the building had to be evacuated immediately.
Quick responses from rescue workers
A total of 51 people were examined on site. The rescue workers acted quickly: gates were opened to improve air circulation and bring the remaining guests to safety. 22 affected people were then taken to hospital to be treated; many received oxygen to relieve symptoms. The situation proved not only worrying but also particularly challenging as the incident took place in the middle of a three-hour kart race and the great enthusiasm of spectators.
As the operator announced on Instagram, the train will remain closed until further notice. The timing of the reopening is still unclear as the technical deficiencies must first be remedied. This is an important measure to ensure that such incidents are avoided in the future.
In summary, the events at the Kartcenter Cologne show how important it is to take safety measures seriously. In these dynamic times, when karting is very popular, the safety and health of participants and spectators must always be the top priority. Let's stay tuned to see when the belts can roll again in the Hahnwald.
