Jacobs Vehicle Systems in Bloomfield has been evacuated for about an hour on Thursday morning after a steel cutting machine caught fire.
Employees grab fire extinguishers and tried to put out the fire, but they were not able to, so they called 911 around 8:30 a.m.
Firefighters rushed to the company on East Dudleytown Road and a couple hundred employees had to vacate the building as firefighters went to work.
The fire was contained and employees were allowed back inside.
The fire marshal will investigate the cause of the fire.
