The surface burning characteristics (flame spread index and smoke developed index) for wood and wood products as measured by American Society for Testing and Materials (44) can be reduced with fire retardant treatments, either chemical impregnation or coatings (48). Fire retardant treatments also reduce the heat release rate of a burning piece of wood (49,50). The heat release rates (51) of the burning materials are an important factor in fire growth. 

The key factor in the development of the tar industry was the accelerated growth of the railroad system. Tracks were laid on wooden sleepers, which were impregnated with coal tar oil to preserve them from rapid decay. The first railway lines started operation in England between Stockton and Darlington in 1825, and in Germany between Nuremberg and Fiirth in 1835.
