ATLANTA (AP) -- Investigators are trying to determine what caused a leak at a Dalton chemical plant that injured two workers.
Dalton Fire Chief Bruce Satterfield said the accident happened Monday morning at a plant owned by MFG Chemical Inc.
A worker was adding a chemical to tank, which triggered a reaction that produced vapor. Satterfield said the vapor escaped before the worker could shut a lid. That worker apparently inhaled the vapor and was flown by helicopter to a burn center in Augusta.
A second worker suffered less-serious injuries.
Company officials said the release was contained to the plant, but Satterfield said some vapor may have escaped the site.
Fire officials briefly advised residents of a nearby apartment complex to stay inside. That precaution was later lifted.
