A large fire Wednesday morning damaged a Lee's Summit business but resulted in just one worker suffering non-life threatening injuries.

The fire at CK Enterprises in the 1200 block of Southwest Jefferson Street, just south of U.S. 50, was reported just after 8 a.m. A large plume of black smoke could be seen for several miles from the business, a chemical and detergent manufacturing plant.

The fire was in an outdoor tank storage area adjacent to the building that had nine tanks capable of containing up to 6,000 gallons. Fire officials said the blaze started while employees were transferring chemicals. Firefighters were able to keep the blaze from spreading into the building, though a nearby semi-tractor trailer and numerous empty storage drums were damaged.

The fire went out at about 9:20 a.m., as fire officials elected to allow it to burn while projecting exposures, in order to eliminate contaminated run-off. Lee's Summit Public Works was able to block a nearby storm water detention pond and contain any contaminated run-off.

Missouri Department of Natural Resources, Environmental Protection Agency and Kansas City Fire Department Hazmat personnel conducted air and particle sampling on and off-site during and after the fire and found no hazards.

About 60 employees in the building evacuated during the fire, and employees were able to return to work in the front half of the building. The back half suffered some heat and smoke damage.

The Lee's Summit Fire Department and Bureau of Alcohol, Tobacco and Firearms are investigating the cause of the fire.
