ASWP03 Ascending Trees
8.0 Work Positioning Technique
During the process of completing all work required in a tree, it is necessary for
the arborist to move in the crown in order to access different work positions.
However, the final anchor location may also be the first work position; in this
case, the arborist must utilize a second point of attachment such as a work
positioning lanyard.
8.1 Work Positioning Techniques
Step Action
Move to work position
Maintain a 3 point contact with tree to stabilize
Ensure that the arborist life line is tight at all
times
Monitor the friction hitch throughout the
climbing action to ensure the friction hitch does
not loosen off
Inspect limb to be cut for defects
When using sharp tools a second
point of attachment such as:
A work positioning lanyard
(Figure 8) or
An arborist life line secured to
a second anchor point (e.g.
double tie in) (Figure 9)
A second point of attachment must be used at
all times when using a sharp tool that could
cut the life line except in circumstances where
the hazards of using a second point of
attachment are greater than not using a second
point of attachment
Note: Every effort must be used to eliminate these
hazards, so the worker can use a second point of
attachment.
