Hurstville Aquatic Centre in Sydney has closed temporarily after 70 litres of Hydrochloric Acid spilled into the spa area due to a faulty valve leaking. The leak caused three hospitalisations and a major evacuation of 150 people. New South Wales Fire and Rescue were called after reports of a toxic smell. Ambulances were called as a precaution and 9 people were treated at the scene due to inhaling the fumes. The scene has now been cleared and the centre will reopen.
