§6295. Anchoring.

(a) Skylines shall be hung in a tree jack or block and securely anchored to a stump, deadman or the base of a live tree outside the work area that would not reach the work area if pulled over. All other rigging shall be anchored to stumps.

(b) Anchors used for fastening guylines and skylines shall be carefully chosen as to position and strength. They shall be tied back if necessary. These anchorages shall be inspected daily for signs of failure, while the operation is in progress.

(c) Stumps shall be adequately notched and barked where the wraps are to be made. Employees shall not stand close to the stump as the guyline or wraps are being tightened.

(d) When tightening is done at the stump, the anchor ends of guylines shall be firmly secured to the stump by passing the guys at least two and one-half times around them; guys may be secured by spikes or cable clips.

(e) Where spikes are used, the first and last turn shall be firmly spiked.

(f) Where wire rope clips are used, they shall be made fast with U bolts on the head or short end of the rope. The minimum number of clips shall not be less than three. The clips should be spaced at a distance equal to approximately six times the diameter of the rope.

(g) Stumps shall be notched to prevent the lines from creeping. Guylines shall be kept tight.

(h) In removing guylines or skylines from stumps, a reversed safety wrap shall be put on before loosening any spikes in the last wrap.

(i) An experienced employee shall be in charge of loosening such guylines or skylines, using all precautions and giving warning before the lines are released.

(j) Safety holdbacks shall be used when necessary for the safety of workers.

(k) Powder is recommended for releasing the last wrap on skylines.

(l) When raising spar trees, stumps used for snubbing shall be deeply notched and guylines held by the haulback or other running lines.

(m) If deadmen or rock bolts are used as anchors, they shall be constructed and maintained in accordance with established principles of mechanics and sound engineering practice.
