Tess Riley, 37, who left the pool with her husband, Thom, and their two-year-old daughter Ruby, said they “vomited” after the incident, which took place shortly after a parent-to-child meeting at centre. training pool on Wednesday morning. In addition to the trauma of the “revealing scenes”, Riley has been left anxious about the possible effects of chlorine gas on her 15-week pregnancy. “I am an angry woman who intends to sue,” she said. Riley, a former Guardian reporter, was among 29 people taken to hospital, where she was treated with oxygen in an isolation room while her clothes were placed in an infection bag. She was spotted by a team of practicing military doctors studying the effects of the chemical attacks. Riley was the last to be released from Royal London late Wednesday night. “The doctors said I was more affected,” he said. But she has not yet discovered what effect, if any, the gas had on her unborn child. Riley and her daughter Ruby were injured by chlorine gas while swimming in the Olympic Park in London. Photo: brochure The London Fire Department said “a large amount of chlorine gas” had been released in the incident. But Riley needs to know if another gas was released that day and so far has not received a response from Better, the company that manages the center. He is now consulting lawyers for legal action against the company. Newham’s council confirmed Friday that environmental health officials are investigating the crash. Riley, who, like her daughter, is still coughing from the incident, said: “I’m really worried about the impact on my pregnancy. It was very traumatic, I do not sleep “. He added: “My maternity team is waiting to learn from me about the gases I was exposed to, so they can find out what treatment I need. The obstetrician who came to see me told me “we do not know how much you have been exposed. “We do not know what has accumulated in the placenta, so we just can not know.” So I need this information, but I do not have it. “ Two days after the incident, Riley is furious with Better for failing to contact her. “Despite many voices in the press about how they support their families, no one at Better has contacted us,” he said. “I want to know what happened, how it happened, what I was exposed to, what the potential long-term health risks are and what they are doing to ensure that such a range will never happen again.” She added: “I’m just surprised that the company has done everything and we have been left in the dark for the whole issue. I want answers “. Riley with daughter Ruby and husband Tom in Stratford.

He said: “We ran out of the building as fast as we could. The staff in the office seemed puzzled by this wall of people with toddlers in their arms running towards them coughing and pulling. It was just a revealing scene. “Outside the building were school children lined up who needed medical help, because these things spilled out of the building through the air ducts.” Riley said she saw at least two people faint. “A woman was found fallen behind the wheel,” he said. “I think she went to her car feeling disgusted.” It is understandable that one of the patients was having so much difficulty breathing that he needed intubation. Riley was taken to Royal London after finding hyperventilation outside the center. Other patients were taken to Newham and Homerton Hospitals. Her daughter, who was coughing and screaming for two hours after the incident, was taken to the pediatric ward of the hospital where she was later discharged. Newham’s council said environmental health officials were investigating the leak. Sources close to the investigation reported that large amounts of chlorine were released when a delivery of hydrochloric acid was accidentally injected into a tank containing chlorine. Riley said: “If this happened, why weren’t the pipes designed to prevent this? And why did it happen when the pool was used? “ Some of those arrested in the incident fled in their swimsuits and glasses. Riley and her family were only half-dressed when it happened. The rest of her clothes also have her keys, phone, glasses and her daughter’s pram in the water center. In a statement, GLL – which trades under the Better brand – said: “Work on the London Water Center is continuing after Wednesday’s incident and means the center is closed. “We are in the process of communicating with customers as it becomes possible to retrieve their personal items. “We understand the concern of the customers, but we can not comment on specific details of the incident until the investigation is completed and we are informed of the full details. However, the released substance was identified as chlorine gas by the London Fire Department. Clients are advised to seek medical help if their condition is worrying.
