Solid log or timber homes and fire safety

According to US National Fire Association, leading causes of occupancy related home fires start:

1-In the kitchen when cooking is left unattended
2-From heating systems that are not professionally checked and maintained.
3-From bad smoking habits resulting in bedding or couch/armchair smoldering.

– Fire resistance of solid log/timber homes
As a designer of log homes, I often encountered difficulties convincing local building departments all over North America of the great fire resistance of log walls.
