PHOENIX (AP) - Several children and a swimming coach who were exposed to a non-life-threatening plume caused by a mixture of chemicals for swimming pools were taken to a hospital after inhaling the fumes.
The Arizona Republic reports that an employee at a location of the Hubbard Family Swim School accidentally mixed the substances Saturday.
The plume was caused by a mixture of muriatic acid and chlorine.
Authorities treated eight people for exposure and sent five people to the hospital as a precautionary measure.
The school was temporarily evacuated and Phoenix fire officials ventilated the building.
Bob Hubbard, owner of the school, says the school plans to review its maintenance procedures with the fire department to ensure safe practices.
He added that the substances are stored separately in the building.
