Fire crews were called to a Tyson chicken processing plant in Nashville, AR in the early hours of Thursday morning after a large fire ignited in the facility, local news organizations reported. Two workers were injured during the incident.

Arriving at the facility at about 2:20 a.m., firefighters found a structure that was completely involved in flames, Nashville Fire Department Chief Justin Thornton told television news station KSLA. Officials are also investigating reports that an explosion occurred. 

“The fire was limited to [a] detached building, so the main section of the plant was not impacted,” the company said in a statement posted to Facebook by a local journalist on Thursday. “Because we’re still assessing the situation, the further processing part of our operation will not run today.”

Tyson said two employees were injured and were given medical attention. 

Firefighters put the fire out by about 3:40 a.m., according to coverage by news broadcaster KTBS. Personnel from four other area fire departments also responded to the scene.
