Despite possible record warmth this weekend, members of the Danbury Fire Department recently trained on removing a simulated arm from a snowblower.  Firefighters used a variety of tools to free the arm.  Department officials are reminding people to review the owners manuals and safe operation recommendations on power equipment. Most injuries associated with snow blowers involve injuries to the hand or finger, including amputation. The typical cause is users trying to clear a clogged auger or discharge chute with their hands.
