Nearly 30 people at a phosphate and mining facility were treated Friday after being exposed to a sulfur dioxide gas leak, Polk County officials said.
Authorities said the call came from Mosaic, 3200 State Road 60 W., at 7:49 a.m. Crews had the leak under control by 9:04 a.m.
After the release of sulfur dioxide that's part of the normal startup operations of a fertilizer plant, the gas stayed as a cloud, exposing 29 people, said Polk County Fire Rescue Battalion Chief Jeremiah Gilley.
Mosaic public affairs manager Debbie Burdett said there always is a gas release, but a mixture of cool, heavy air caused the cloud, which normally would dissipate, to hug the ground.
