Carol Stream, IL – A carbon monoxide leak at a warehouse facility in Carol Stream caused 15 employees to be taken to area hospitals, the Carol Stream Fire Department reports.

According to Battalion Chief Terry Ruch, a malfunctioning fork lift truck at the F.I.C. America Corp. produced excessive amounts of carbon monoxide and a number of employees reported feeling ill.

“We treated 27 patients at the scene,” Ruch said. “Twelve were treated and refused to be hospitalized. The other 15 were taken to four area hospitals.” He said none of the injuries appeared to be serious. There were about 27 people working in the area at the time, Ruch said. “We treated them all.”

Ruch said the fork lift runs on propane. A unspecified malfunction caused it to produce an excessive amount of carbon monoxide exhaust fumes.

The leak was first reported just before 3 p.m. at the F.I.C. America warehouse at 485 E. Lies Rd. The site was secured just after 4 p.m., Ruch said. About 12 ambulances from five different fire departments were used to transport patients.
