(CNN) — A chemical release at the Intel complex in Chandler, Arizona, on Saturday sent 11 people to local hospitals, where they were reported in stable condition, said fire department spokesman Tom Dwiggins.
Forty-three people suffered breathing difficulties and skin and eye irritations, but only 11 of them were taken to medical centers, he said.
The leak began at 6:30 a.m. Saturday but has since been stopped, Dwiggins said later Saturday morning.
The cause is under investigation, he said.
