6/3/17 AURORA – Level II HazMat (Internal) Hydrochoric acid leak Phillips Park Family Aquatic Center 828 Montgomery Rd. – Video by Dave Weaver
At 6:17 p.m. on 6-3-17 the Aurora Fire Department responded to a hazardous material incident in the 800 block of Montgomery Road. Upon arrival firefighters found an unknown substance leaking from a small out-building next to the main pump house for the aquatic center. The incident was escalated to a Level II Hazardous Material Response which brought the Aurora Fire Department Hazardous Material Team to the scene. Upon investigation it was determined that the substance was hydrochloric acid, a chemical used to raise the pH of water in swimming pools. It was estimated that between 5 to 10 gallons of product leaked from a 30-gallon poly tank. The leak was noticed by an employee and 911 was called immediately. There were patrons swimming at the facility at the time of the incident and they were quickly evacuated by employees before the fire department arrival without incident. The hazardous materials team used sodium bicarbonate to neutralize the product rendering it safe for cleanup. The cause of the leak was due to a 500-gallon poly tank that was filled the day before. It is uncertain why, however the 500-gallon poly tank started to backfill with water from a pool water line and started to push product into the 30-gallon poly tank which resulted in it spilling over. At this time there is no specified dollar loss for this incident and there were no reported injuries to civilians or firefighters.
