I have always wondered whether it would be possible to create a simple and economical system to quickly cover a house with several feet of fireproof foam in an emergency. If you could get such a system to work, people would buy it.
We ran AFFF systems in race cars. They are maintenance intensive.
or event have a system in developments or a community to be able to do multiple homes?
Masonry construction, metal roofs, and metal roll down shutters should greatly reduce risk. Lots of gravel landscaping near the house, clear the trees back (it looked like a lot of the burned houses there were actually on clear cut land).
One can’t eliminate the danger, but one can affirmatively reduce risk.
I do remember 20-30 years ago, a special foam was demonstrated that when pressure injected INTO a burning structure would rob the fire of oxygen and snuff it out.
What happened to it? I have no idea.
