Juliana Faustino Basseto, a 27-year-old teacher, tragically died following her visit to a swimming pool at C4 GYM in São Paulo. Initial investigations suggest that the mixing of several chemical products intended for maintaining the pool may have caused her death, alongside toxic exposure to her and at least two other individuals, one of whom is her husband who remains hospitalized. The toxic mixture was reportedly not added to the pool water but was prepared manually by a gym attendant shortly before the swimming lesson concluded.

The incident occurred on Saturday, and after feeling unwell, Juliana was rushed to a hospital in Santo André, where she ultimately passed away. Authorities, led by Detective Alexandre Bento from the 42nd Police Department, are currently examining the situation and the specific chemicals involved, which remain unidentified. It appears that the attendant left the mixture near the swimming area, which may have released harmful substances into the confined air of the gym environment, particularly because the pool is heated and poses additional risks of air contamination.

This case raises critical safety concerns regarding the handling of pool chemicals and the potential health risks to patrons in fitness facilities. The investigation will likely highlight the need for better safety protocols in gyms to prevent similar tragic incidents from occurring, ensuring proper procedures are established for managing chemical products used in pool maintenance to protect both staff and swimmers.
