There have been numerous cases of houses burning down or blowing up from gas leaks when THE HOUSES WERE NOT SERVED BY GAS AT ALL. Even without a propane tank present etc. In those cases there were underground gas leaks (severed pipes) blocks or hundreds of yards away. The gas traveled along the gravel sewer pipes were buried in and found its way into and around the house foundations. Made for big explosions and fires.
