A small chlorine leak at a Chanhassen swim school Sunday led firefighters to evacuate the facility and sent four people to the hospital as a precaution.
Chanhassen Fire Department Assistant Chief Ed Coppersmith said a doctor who happened to be at the scene described the problems as "very, very minor." He said four people, including three children, were taken to area hospitals for exams. He did not know their status or what hospitals they were taken to Sunday.
The cause of the leak is under investigation.
About 30 people were evacuated from Foss Swim School in Chanhassen shortly before 3 p.m.
