Today's buildings are not safer when it comes to fires and firefighting. They are more dangerous, especially for firefighters, and it is proven fact witnessed every day across the country. Smoke ignites faster. Open space truss construction and glued, wood by-products burn many times faster than previous construction materials and methods. Vinyl siding melts quickly, allowing fire to penetrate into structures. When exposed to heat and fire these materials fail, causing partial or total collapse within minutes. Few homes have sprinklers. Research it.
