The tie-in position should be above the work area and
located in such a way that a slip would swing the arborist
away from any energized electrical conductors or other
identied hazard.
While climbing, the arborist should climb on the side of
the tree that is away from energized electrical conduc-
tors as required in Tables 1 and 2.
Footwear, including lineman’s overshoes, having electri-
cal-resistant soles, shall not be considered as providing
any measure of safety from electrical hazards.
Rubber gloves, with or without leather or other protec-
tive covering, shall not be considered as providing any
measure of safety from electrical hazards.
Ladders, platforms and aerial devices, including insulat-
ed aerial devices, shall be subject to minimum approach
distances in Table 1 and 2.
Aerial devices and attached equipment (such as chip-
pers) contacting energized electrical conductors shall be
considered energized. Contact shall be avoided, except
where emergency rescue procedures are being carried
out. Emergency rescue should be performed in accor-
dance with 4.3.
STORM WORK AND EMERGENCY
CONDITIONS-LINE CLEARANCE
Line clearance shall not be performed during adverse
weather conditions such as thunderstorms, high winds
and snow and ice storms.
Qualied line-clearance arborists and qualied line-
clearance arborists trainees performing line clearance
in the aftermath of a storm or under similar conditions
shall be trained in the special hazards associated with
this type of work.
Line-clearance operations shall be suspended when
storm work or emergency conditions develop involving
energized electrical conductors. Electrical system own-
ers/operators shall be notied immediately.
