   I was 30 feet off the floor working on a bridge crane once, and a 
laborer on the ground:

1) Removed the red flag tying the fuse-box closed**

2) Installed the 2 fuses I had removed from the crane circuit

3) Threw the crossbar switch, and

4) Walked back over to the control pendant and started moving the bridge 
down the shop.

   All without ever looking up, or apparently even removing his brain 
from his anus.

   I was VERY fortunate that I didn't have my hands anywhere near 
current or moving parts, but I was sitting on the edge of the bridge and 
damn near fell off when it started moving.

   The guy that did it was quite offended when I started throwing tools 
at him.

** There were 2 emergency stop buttons INSIDE that box, so I wasn't 
allowed to padlock it.  The silver lining to this incident was that my 
company finally agreed to move them out of the fuse box.
