Don't know if you've ever had an open fire - but it's exactly the same reason that you would spray water onto the base of the coals in the fireplace if you have a chimney fire. Just on a larger scale.

I'm also quite baffled as to why you think you know more about putting out a fire than dozens of trained firefighters .
