Or. Admin. Code § 437-007-1530

Current through Register Vol. 64, No. 1, January 1, 2025

Section 437-007-1530 - Three Point Climbing System

(1) Use a three-point climbing system (three-points of contact) when tree climbing.

NOTE: A three-point system is not required when using an approved rappel or ascender system.

(2) While tree climbing, three-points of contact must be firmly in place on a secure surface before moving to another point.

NOTE 1: Each hand and foot (or climbing spur) is considered a potential point of contact.

NOTE 2: Other parts of the body, such as a hooked knee or armpit, may be considered contact points if the body part is physically capable of supporting the full body weight.

NOTE 3: A lanyard around the tree bole or appropriate limb that is secured to the safety harness or climbing belt on both ends counts as two points of contact.

(3) Do not use unsound branches or stubs for support.

(4) Climbing without being secured to the tree is not allowed except in conifers when, in the judgment of the qualified climber, the density of branches growing from the stem would require so many limb-overs, attaching and reattaching the lanyard, as to become a greater hazard than simply climbing that section of the tree.

(5) Climbing in conifers without being secured is not allowed above the 4-inch bole diameter.
