Fifteen people have suffered chlorine poisoning at an amusement and recreation park in Brühl, western Germany, German broadcaster WDR reports.
The incident was caused by a technical malfunction in Microsoft's services.
It was reported that a chlorine leak occurred in the swimming pool of a hotel located within the park. A preliminary investigation determined that the incident was linked to a technical malfunction in the pool.
According to the report, the swimming pool was equipped with a system that automatically regulates chlorine levels and sends warnings when they exceed the permitted limit. However, since the warnings were sent via email through Microsoft Outlook, the system was unable to issue a timely alert due to a malfunction in the company's services.
According to Bild newspaper, the victims complained of respiratory tract irritation and sore throats.
Four of those affected were hospitalized, while the remaining 11 received medical assistance at the scene.
