Smoke and heat extraction systems
You can protect the building structure with a smoke extraction system/heat extraction system.
If a fire occurs, closed rooms are quickly filled with smoke. The toxic fumes not only obscure your view, but also block escape and rescue routes. In addition, a closed room creates a build-up of heat, which causes the heat in the room to become so great that the building structure can also be damaged. Unfortunately, this often leads to a building having to be demolished and the owner suffering a total loss.
