6
The removal of a branch or branches at the point of
original or the shortening of a branch or branches.
The opening that is created any time the tree's
protective bark covering is penetrated, cut, or removed.
Pruning a live branch creates a wound, even when the
cut is properly made.
An entity that delivers a public service such as
electricity or communication.
The physical area occupied by the utility's facilities and
the additional space required to ensure its operation.
When cutting is done along the bottom rails of the
guide bar, the reaction on the saw is a pull away from
the operator. When the top of the guide bar is used,
the reaction pushes the saw toward the operator. Both
are normal reactions that must be controlled by the
operator.
A tree worker who, through related training and on-the-
job experience is familiar with the techniques in line
clearance and has demonstrated his/her ability in the
performance of the special techniques involved. This
qualified person may or may not be currently employed
by a line clearance contractor.
Person(s) who, through related training and on-the-job
experience, are familiar with the hazards of pruning,
trimming, repairing, maintaining or removing trees and
with the equipment used in such operations, and have
demonstrated ability in the performance of the special
techniques involved.
The reasons for tree pruning may include, but are not
limited to, reducing hazards, maintaining or improving
tree health and structure, improving aesthetics, or
satisfying a specific need such as: removing diseased,
dead, dying, decayed, interfering or obstructing
branches; training young trees; and, utility line
clearance. Before pruning, the primary objective
should be clearly defined. That objective should be
accomplished in the manner most beneficial to the
health of the tree.
