We got a kick out of this U.S. Navy office safety video from the 1940s.

Although the office environment (and the tone of the safety videos) has changed a bit since then, the underlying point of the video remains relevant – some personalities make an individual more prone to carelessness and, even in the most mundane of environments, that carelessness can cause accidents.
