Nineteen people were treated and hospitalized after being exposed to a pool chemical at a Thousand Oaks swim club Wednesday evening, officials said.
The incident occurred at Daland Swim School in the 100 block of East Wilbur Road around 6:30 p.m.
Swim instructors said it all happened in a matter of seconds during a routine swim practice. The children in the pool started coughing and some complained they couldn’t breathe.
“That’s never happened here before, so for us it was quite a scary moment,” facility owner Leslie Darland-James said.
