Dozens of people were taken to hospital with breathing problems today after a bungled delivery to the London 2012 Aquatics Centre sparked a ‘chemical reaction’ that led to deadly Chlorine gas being pumped out.
With people who inhaled the toxic substance in the carpark, more than 200 people were removed from the arena.
29 individuals were taken to the hospital, where they kept it closed off for 5 hours. One patient was taken to hospital by a paramedic while many swimmers were still wearing their goggles and trunks. They were then wrapped up in foil blankets in order to stay warm.
Almost 50 people needed care at the scene in east London, just yards from West Ham United’s world famous London Stadium.
London Fire Brigade stated that a high quantity of chlorine gas was released from the Aquatics Centre in Queen Elizabeth Olympic Park, London. This happened due to a chemical reaction. According to the Aquatics Centre, the incident occurred when the facility management company took possession of the pool chemicals.
Photographs from the scene show a blue car with several tanks of chloric acid left outside. It is not known what happened next, but for safety reasons, experts recommend that hydrochloric acid and pool chlorine should never be stored together – and should absolutely never, ever be mixed, under any circumstances – because they can cause the release of chlorine gas.
If inhaled, chlorine gas is a deadly substance that has even been used to weaponize war. You may also experience shortness of breathing, blurred vision and burning sensations in your nose, throat, and eyes.
London Ambulance Service stated that 29 individuals were transported to the hospital by London’s Queen Elizabeth Olympic Park.
Darren Farmer (London Ambulance Service’s gold commander) said that they responded this morning to a major incident in Stratford at the London Aquatic Centre. He was joined by colleagues from the Metropolitan Police and London Fire Brigade.
The significant amount of resources sent included 13 ambulance crews with advanced paramedics, 2 fast response car medics, 2 incident officers, 1 medical adviser, and 3 members of the hazardous area team (HART).
“We also sent medics to London from the Air Ambulance. We took in 29 patients and evaluated 48 others. Majority of the patients had minor breathing difficulties.
LAS stated that it had reacted shortly after 3pm.

Following a gas-related incident in London, a truck carrying hydrochloric acids was left parked outside of the Aquatics Centre at Queen Elizabeth Olympic Park.
