On Thursday afternoon you suddenly hear a loud crashing noise from an office adjoining your workplace. Others have also heard the noise and come running.
A large heavy whiteboard that had been sitting on a window ledge had suddenly fallen. Jason hadn't seen it coming because, although he was within a metre of the whiteboard, he was facing the other way using his computer.
Jason was struck on the head, left shoulder, arm and hand. He was visibly dazed, holding his left shoulder and arm and his hand was swelling quickly.
