Following the fire code is a challenge for the best of us;  it is even a challenge for The White House.  Recently The White House released a video "Catching Up With The Curator, The White House Fire of 1814".  Terrific history video that shows the fire damage to the north portico that is still visible.  Right next to the visible fire damage is a blockd fire extinguisher, ironic.

YouTube Video:  Check out the 15 second mark,  but the whole thing is worth watching.
