A worker’s arm was severed in an incident at the construction site for a new BMW plant in Greer, SC.

Doctors reattached the limb, and initial results appear positive.

The unidentified worker, a plumbing subcontractor, was operating a lift machine with his arm extended outside of its cage.

When he went through a doorway, his arm hit a vertical I-beam and was severed at a point between the elbow and wrist.

After the surgery, the arm regained sustained blood flow, a sign the procedure may have been successful.

OSHA is investigating.
