I could keep going on, but you can visit the site, and find much more than these.
The reason I like to bring these to the attention of my fellow engineers, is that a whole lot of these situations were preventable, by either taking precaution or better design. And, to point out that actions have consequences.
The first one I have you, the safety list should be a prime photo to illustrate that accidents are preventable. The scenario pictured here is an accident that has found a place to happen.
I hope you find something beneficial on this site for what you are trying to do.
