OSHA EXCERPTS: (CLEARANCE DISTANCE)
The following are excerpts from OSHA Standards. They are not complete and do not cover all safety work
rules.
PARTIAL EXCERPT FROM SUBPART S - ELECTRICAL: (02-01-1998 EDITION)
1910.333 Selection and use of work practices.
(c), (i) Unqualified person.
(A) When an unqualified person is working in an elevated position near overhead lines, the location shall be
such that the person and the longest conductive object he or she may contact cannot come closer to any
unguarded, energized overhead line than the following distances:
1.
For voltages to ground 50kV or below - 10 feet (3.05 m);
2.
For voltages to ground over 50kV - 10 feet (3.05 m) plus four inches (101.6 mm) for every 10kV over
50kV.
(B) When an unqualified person is working on the ground in the vicinity of overhead lines, the person may
not bring any conductive object closer to unguarded, energized overhead lines than the distances given in
paragraph (c)(3)(i)(A) of this section.
NOTE: For voltages normally encountered with overhead power line, objects which do not have
an insulating rating for the voltage involved are considered to be conductive.
EXCERPT FROM OSHA SUBPART V - POWER TRANSMISSION AND DISTRIBUTION (11-14-
1990 EDITION)
1926.950 General Requirements (c) Clearances. The provisions of paragraph© (1) or (2) of this section shall
be observed.
(1) No employee shall be permitted to approach or take any conductive object without an approved
insulating handle closer to exposed energized parts than shown in Table V-1, unless:
(i) The employee is insulated or guarded from the energized part (gloves or gloves with sleeves rated for the
voltage involved shall be considered insulation of the employee from the energized part), or
(ii) The energized part is insulated or guarded from him and any other conductive object at different
potential, or
(iii) The employee is isolated, insulated, or guarded from any other conductive object(s), as during live-line
bare-hand work.
(2)(i) The minimum working distance and minimum clear hot stick distances stated in Table V-1 shall not be
violated. The minimum clear hot stick distance is that for the use of line-line tools held by lineman when
performing live-line work.(e)(15) The minimum clearance distances for live-line bare-hand work shall be as
specified in Table V-2. These minimum clearance distances shall be maintained from all grounded objects
and from lines and equipment at a different potential than that to which the insulated Cable Placer is bonded
unless such grounded objects or other lines and equipment are covered by insulated guards. These
distances shall be maintained when approaching, leaving and when bonded to the energized circuit.
