CONCORD (CBS) – A tree worker has been hurt while cleaning up debris from the tornado that hit Concord Monday morning.

The worker was doing private work for a homeowner on Lexington Road, one of the hardest hit areas. He suffered lacerations to his face when parts of a tree shot out of a wood chipper.

“He was struck in the head to the best of my knowledge. He was transported to Lahey Clinic,” said Assistant Chief Thomas Judge of the Concord Fire Department.

The worker was part of a significant number of crews doing incredibly risky work in an effort to clean up the aftermath of the tornado.

The worker’s injuries are said to be minor.
