OAR 437-007-0925: Cable Yarding Work Practices

(1) Personnel must not ride hooks, lines, rigging, logs suspended in the air or being moved. (2) Personnel must not hold onto haywire, running lines, drop lines or chokers as an assist when walking uphill. (3) Personnel must not work in the bight of lines under tension. EXCEPTIONS: Personnel may be in the bight of lines when: (a) Minor positioning of the rigging is needed to set chokers. (b) They are protected by standing timber, terrain, or other objects of sufficient size to assure their safety. NOTE: "Lines under tension" means when: (a) Logs are being moved or suspended. (b) The rigging or carriage is moving to the landing or returning to the brush. (c) Lines are tight-lined to clear up the road. (d) Any movement or tightening of the line(s) other than that needed for minor positioning of the rigging or carriage to set chokers. (4) Personnel must be in the clear of all lines, rigging and chokers until movement has stopped. Swinging chokers, hooks and rigging must be lowered to the ground. (5) Personnel must be in the clear of trees, logs, root wads, chunks, rolling material, all lines and rigging before any lines are moved. (6) Personnel must not stand next to skyline or running line anchor straps under tension. (7) A minimum of one choker setter in each crew must be a qualified choker setter. (8) Only one employee in any crew can give signals or voice communication at the point where chokers are being set. NOTE: Any person is authorized to give a stop signal when an employee is in danger or any other emergency condition is apparent. (9) At least two members of the rigging crew must carry transmitters for each signal and control system being operated where chokers are being set. (10) When only one person is setting chokers on any cable yarding system, they must: (a) Carry transmitters for each signal and control system being operated where chokers are being set. (b) Be in clear view of the yarder operator or another person with transmitters for each signal and control system being operated where chokers are being set.
