An ammonia leak at a Morristown food processing plant prompted the evacuation of about 200 people Wednesday.

Hamblen County Emergency Management Director Chris Bell said an ammonia leak was reported at Koch Foods, 123 S. Fairmont Ave., at 11:45 a.m. The leak came from a ruptured line within the plant, he said.

About 150 employees evacuated.

Bell said the anhydrous ammonia leak was contained to the building, but some gas from the ammonia was moving out into the air outside the building.

The Morristown Fire Department, Morristown Police and EMA officials also evacuated eight nearby businesses with approximately 50 people, Bell said.

No injuries have been reported. Some people were examined on scene, but no one was transported to the hospital, Bell said.

The buildings were still evacuated around 2:45 p.m. Wednesday. Bell said there would be a few hour waiting period for the gas in the air to dissipate.

Koch Food is a chicken processor.
