Falling and bucking—Bucking.
(1) The tree (and root wad if applicable) must be carefully examined to determine which way the logs (and root wad) will roll, drop, or swing when the cut is completed. No worker shall be allowed in this danger zone during cutting. The cut must be made from a position that will not expose the cutter to potential injury.
(2) Logs must be completely bucked through whenever possible. If it becomes hazardous to complete a cut, then the log must be marked and identified by a predetermined method. Rigging crews must be instructed to recognize such marks and when possible, cutters must warn the rigging crew of locations where unfinished cuts remain.
(3) Cutters must give a timely warning to all persons within range of any log that may have a tendency to roll after being cut off.
