Authorities are investigating what might have caused a Haltom City firefighter to be overcome and taken to a local hospital.
The fire was called in about 7:05 p.m. Tuesday at a Tyson Foods, Inc plant at 3900 Meacham Blvd. Units from the Fort Worth Fire Department were also called out.
The firefighter was taken to the hospital as a precaution and released late Tuesday, said Fred Napp, Haltom City fire marshal.
Napp said two employees at the plant were treated on scene.
“We are still trying to identify the substance,” Napp said Tuesday.
Napp speculated that the unknown substance came from plastic burning on a belt attached to some machine in the plant.
The small fire was extinguished and no other injuries were reported, Napp said.
