VIDEO: Concussions are a big concern in the sports world, but they're also a worry in the workplace. One career that poses a serious risk is firefighting. Fond du Lac Fire Rescue has made a new policy for employee physical exams. Now every firefighter has to get baseline concussion testing. "About 68,000 injuries to firefighters throughout the United States every year and about 13% of those are head injuries," explained Captain Jim Wamser. Wamser told FOX 11 News firefighters often have to pull down parts of burning buildings to get to the flames.
