In Germany, only a small portion of our houses are wood framed. But we have high standards, so our wood frames are protected and escape routes in special are covered by non burning plates. In addition, building stairs with the right wood can make them more sustainable to fire than concrete.

Overall, that's a very bad decision they made or want to make and there are even more technology available to prevent any form of fire in wood framed houses. Example: circuit breakers with lightning detection.
