Firefighters were called to the General Motors plant in Arlington early Tuesday morning after a worker somehow got caught in a piece of equipment on the assembly line.
The incident took place in the general assembly area where a woman, who has not been identified, got her foot caught in a piece of equipment.
The plant requested an air ambulance to transport the worker at 6:17 a.m.
"The employee was caught in a piece of equipment and her leg was injured," said GM Communications Manager Donna McLallen."Quick actions by her co-workers once they realized what happened prevented further injury."
Production temporarily stopped where the incident happened, but not on the entire production line.
"We are investigating internally to see exactly what happened to prevent this kind of thing from happening in the future," McLallen added.
The worker was flown to John Peter Smith Hospital in Fort Worth with non life-threatening injuries.
