Ok Kirk, it was the louvered doors that caused the massive spread of the Marco Polo fire, not the lack of a sprinkler system.  Had the residents complied and kept their fire doors shut, then the fire would have been contained.  Loss of life...who knows.  Spreading to six floors due to the wind tunnel effect of open doors....no way.  Time to cancel your pending legislation to mandate all older buildings have a sprinkler system.
