An early Saturday morning fire at a Des Plaines manufacturing plant could have turned out much worse, officials say, but no one was injured in the blaze.

"The potential was there for much greater involvement and damage," said Des Plaines Fire Chief Alan Wax.

More than a dozen emergency agencies responded to the fire just before 6 a.m. at Contour Saws Inc., 1217 E. Thacker St. Employees were working in the facility, which produces saw blades.

Wax said the fire was contained and extinguished within about an hour. Damage was limited to a section inside the factory and the roof. The cause is still be investigated, Wax said.

"The firefighters did an excellent job of identifying the fire location, containing it and extinguishing," Wax said.

Because of the location of the fire, a box alarm was raised, drawing in support from surrounding suburbs.

Responding agencies included fire departments in Arlington Heights, Rosemont, Mount Prospect, Park Ridge, Elk Grove Township, Rolling Meadows, Wheeling, Buffalo Grove and Morton Grove. In addition, the Des Plaines Police Department, local emergency management agency and the Metropolitan Emergency Support Services were on the scene.
