   Seems easy is buildings with exposed piping in an eight-foot high room.   
     And there is no lower limit to stupid.

   The air is replaced by Halon.

   I would like to poke a hole in that   
   diesel-can-be-used-to-extigguish-a-fire nonsense.   
      
   My daughter drives a big truck (or did)--she was in a sideswiping   
   accident (details of which will never be known for sure) but what is   
   known is that her truck (with a fuel tank containing diesel) rubbed   
   along the side of a stopped truck (with a fuel tank containing diesel)   
   and by the time her truck came to rest her truck was fully engulfed in   
   flame and (thanks to an unidentified Good Samaritan) she escaped with   
   the clothing she had on.   
      
   She was driving the "bacon" truck--you can see from the shot of the back   
   of the "biscuit" (flour, actually) truck tht the "rear-ended" is total   
   bullshit.
