I made a playlist of the 5 clips on a miniseries on Web Machine Safety I just put on my AllWebHandlingChannel of Youtube.

These include clips on Accident Case Histories, Codes and Standards, Hazards, Human Factors and Accidents Happen.
Let me know if you are aware of other good web machine safety clips on YouTube and I will add them to this playlist.
