One worker was critically injured and six hurt on Thursday in an explosion at the Arizona-based operations of the company that makes Taser weapons, fire officials said. The male worker was taken by ambulance to a local burn unit with life-threatening injuries from the explosion at Taser International, Inc. in Scottsdale, said fire spokesman Battalion Chief Chris Schibi. The other workers sustained concussion-related symptoms and were reported to be in stable condition at area hospitals, Schibi said.
