A two-alarm fire and a hazardous material call brought about 50 firefighters and 14 pieces of equipment Tuesday afternoon to a burning chemical plant in Marietta.

The fire was reported shortly after 2 p.m. at Sinergy Elastomers Inc., a producer of waterproofing materials at 922 Mountain Industrial Drive NW near White Circle Drive in Marietta. The building is in an industrial park at the base of Kennesaw Mountain.

Ten engines, three ladder trucks and a rescue unit responded.

"Heavy smoke was showing" when the firefighters arrived, and they were told hazardous chemicals were involved, leading to the hazmat call, according to firefighter Denell Boyd, spokeswoman for the Cobb County Fire Department.

No one was injured in the blaze, though a firefighter was taken to a hospital as a precaution for heat-related blood pressure issues, Boyd said.

The blaze began when hot waterproofing chemical spilled from a mixing barrel and ignited the propane tank of a nearby forklift, Boyd said.

Everyone inside the plant got out safely, but the building sustained extensive damage as firefighters took up defensive positions outside to put out the blaze.

The fire was declared under control at 3:39 p.m., Boyd said.
