(2) Self-propelled mobile falling equipment used for falling trees must be designed, or have auxiliary equipment installed, that will cause the tree to fall in the intended direction.
(3) Until the machine operator has acknowledged that it is safe to do so, no employee will approach a mechanical falling operation closer than a minimum of two tree lengths of the trees being fell.
(4) Mechanized falling must be conducted in a way that does not endanger people or equipment.
