connected to and supplied from another
circuit of higher voltage (as in the case
of an autotransformer), both are considered as of the higher voltage, unless
the circuit of lower voltage is effectively grounded, in which case its voltage is not determined by the circuit of
higher voltage. Direct connection implies electric connection as distinguished
from
connection
merely
through electromagnetic or electrostatic induction.

NOTE: OSHA is staying the enforcement of
the following paragraphs of § 1910.269 until
November 1, 1994: (b)(1)(ii), (d) except for
(d)(2)(i) and (d)(2)(iii), (e)(2), (e)(3), (j)(2)(iii),

OSHA is also staying the enforcement of
paragraphs (n)(6) and (n)(7) of § 1910.269 until
November 1, 1994, but only insofar as they
apply to lines and equipment operated at 600
volts or less. Further, OSHA is staying the

(a) General—(1) Application. (i) This
section covers the operation and maintenance of electric power generation,
control, transformation, transmission,
and distribution lines and equipment.
These provisions apply to:
(A) Power generation, transmission,
and distribution installations, including related equipment for the purpose
of communication or metering, which
are accessible only to qualified employees;
NOTE: The types of installations covered by
this paragraph include the generation, transmission, and distribution installations of
electric utilities, as well as equivalent installations of industrial establishments.
Supplementary electric generating equipment that is used to supply a workplace for
emergency, standby, or similar purposes
only is covered under subpart S of this part.
(See paragraph (a)(1)(ii)(B) of this section.)

(B) Other installations at an electric
power generating station, as follows:

§ 1910.269

(1) Fuel and ash handling and processing installations, such as coal conveyors,
(2) Water and steam installations,
such as penstocks, pipelines, and
tanks, providing a source of energy for
electric generators, and
(3) Chlorine and hydrogen systems;
(C) Test sites where electrical testing
involving temporary measurements associated with electric power generation, transmission, and distribution is
performed in laboratories, in the field,
in substations, and on lines, as opposed
to metering, relaying, and routine line
work;
(D) Work on or directly associated
with the installations covered in paragraphs (a)(1)(i)(A) through (a)(1)(i)(C) of
this section; and
(E) Line-clearance tree-trimming operations, as follows:
(1) Entire § 1910.269 of this part, except paragraph (r)(1) of this section, applies to line-clearance tree-trimming
operations performed by qualified employees (those who are knowledgeable
in the construction and operation of
electric
power
generation,
transmission, or distribution equipment involved, along with the associated hazards).
(2) Paragraphs (a)(2), (b), (c), (g), (k),
(p), and (r) of this section apply to lineclearance tree-trimming operations
performed by line-clearance tree trimmers who are not qualified employees.
(ii)
Notwithstanding
paragraph
(a)(1)(i) of this section, § 1910.269 of this
part does not apply:
(A) To construction work, as defined
in § 1910.12 of this part; or
(B) To electrical installations, electrical safety-related work practices, or
electrical maintenance considerations
covered by subpart S of this part.
NOTE 1: Work practices conforming to
§§ 1910.332 through 1910.335 of this part are
considered as complying with the electrical
safety-related work practice requirements of
this section identified in Table 1 of appendix
A–2 to this section, provided the work is
being performed on a generation or distribution installation meeting §§ 1910.303 through
1910.308 of this part. This table also identifies
provisions in this section that apply to work
by qualified persons directly on or associated
with installations of electric power generation, transmission, and distribution lines or

equipment, regardless of compliance with
§§ 1910.332 through 1910.335 of this part.
NOTE 2: Work practices performed by qualified persons and conforming to § 1910.269 of
this part are considered as complying with
§§ 1910.333(c) and 1910.335 of this part.

(iii) This section applies in addition
to all other applicable standards contained in this part 1910. Specific references in this section to other sections of part 1910 are provided for emphasis only.
(2) Training. (i) Employees shall be
trained in and familiar with the safetyrelated work practices, safety procedures, and other safety requirements in
this section that pertain to their respective job assignments. Employees
shall also be trained in and familiar
with any other safety practices, including applicable emergency procedures
(such as pole top and manhole rescue),
that are not specifically addressed by
this section but that are related to
their work and are necessary for their
safety.
(ii) Qualified employees shall also be
trained and competent in:
(A) The skills and techniques necessary to distinguish exposed live parts
from other parts of electric equipment,
(B) The skills and techniques necessary to determine the nominal voltage of exposed live parts,
(C) The minimum approach distances
specified in this section corresponding
to the voltages to which the qualified
employee will be exposed, and
(D) The proper use of the special precautionary techniques, personal protective equipment, insulating and
shielding materials, and insulated tools
for working on or near exposed energized parts of electric equipment.

NOTE: For the purposes of this section, a
person must have this training in order to be
considered a qualified person.

(iii) The employer shall determine,
through
regular
supervision
and
through inspections conducted on at
least an annual basis, that each employee is complying with the safety-related work practices required by this
section.
(iv) An employee shall receive additional training (or retraining) under
any of the following conditions:
(A) If the supervision and annual inspections
required
by
paragraph

(a)(2)(iii) of this section indicate that
the employee is not complying with
the safety-related work practices required by this section, or
(B) If new technology, new types of
equipment, or changes in procedures
necessitate the use of safety-related
work practices that are different from
those which the employee would normally use, or
(C) If he or she must employ safetyrelated work practices that are not
normally used during his or her regular
job duties.
NOTE: OSHA would consider tasks that are
performed less often than once per year to
necessitate retraining before the performance of the work practices involved.

(v) The training required by paragraph (a)(2) of this section shall be of
the classroom or on-the-job type.
(vi) The training shall establish employee proficiency in the work practices required by this section and shall
introduce the procedures necessary for
compliance with this section.
(vii) The employer shall certify that
each employee has received the training required by paragraph (a)(2) of this
section. This certification shall be
made when the employee demonstrates
proficiency in the work practices involved and shall be maintained for the
duration of the employee’s employment.
NOTE: Employment records that indicate
that an employee has received the required
training are an acceptable means of meeting
this requirement.

(3) Existing conditions. Existing conditions related to the safety of the work
to be performed shall be determined before work on or near electric lines or
equipment is started. Such conditions
include, but are not limited to, the
nominal voltages of lines and equipment, the maximum switching transient voltages, the presence of hazardous induced voltages, the presence
and condition of protective grounds
and equipment grounding conductors,
the condition of poles, environmental
conditions relative to safety, and the
locations of circuits and equipment, including power and communication
lines and fire protective signaling circuits.
