to perform his duties safely at his level
of training.
(36) System operator/owner. The person
or organization that operates or controls the electrical conductors involved.
(37) Telecommunications center. An installation of communication equipment under the exclusive control of an
organization providing telecommunications service, that is located outdoors or in a vault, chamber, or a
building space used primarily for such
installations.
NOTE: Telecommunication centers are facilities established, equipped and arranged in
accordance with engineered plans for the
purpose of providing telecommunications
service. They may be located on premises
owned or leased by the organization providing telecommunication service, or on the
premises owned or leased by others. This definition includes switch rooms (whether
electromechanical, electronic, or computer
controlled), terminal rooms, power rooms,
repeater rooms, transmitter and receiver
rooms, switchboard operating rooms, cable
vaults, and miscellaneous communications
equipment rooms. Simulation rooms of telecommunication centers for training or developmental purposes are also included.

(38) Telecommunications derricks. Rotating or nonrotating derrick structures permanently mounted on vehicles
for the purpose of lifting, lowering, or
positioning hardware and materials
used in telecommunications work.
(39) Telecommunication line truck. A
truck used to transport men, tools, and
material, and to serve as a traveling
workshop for telecommunication installation and maintenance work. It is
sometimes equipped with a boom and
auxiliary equipment for setting poles,
digging holes, and elevating material
or men.
(40) Telecommunication service. The
furnishing of a capability to signal or
communicate at a distance by means
such as telephone, telegraph, police
and firealarm, community antenna television, or similar system, using wire,
conventional cable, coaxial cable, wave
guides, microwave transmission, or
other similar means.
(41) Unvented vault. An enclosed vault
in which the only openings are access
openings.
(42) Vault. An enclosure above or
below ground which personnel may

enter, and which is used for the purpose of installing, operating, and/or
maintaining equipment and/or cable
which need not be of submersible design.
(43) Vented vault. An enclosure as described in paragraph(s) (42) of this section, with provision for air changes
using exhaust flue stack(s) and low
level air intake(s), operating on differentials of pressure and temperature
providing for air flow.
(44) Voltage of an effectively grounded
circuit. The voltage between any conductor and ground unless otherwise indicated.
(45) Voltage of a circuit not effectively
grounded. The voltage between any two
conductors. If one circuit is directly
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.

§ 1910.269 Electric power generation,
transmission, and distribution.
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
enforcement of paragraph (v)(11)(xii) of
§ 1910.269 until Februrary 1, 1996.

(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:

§ 1910.269

(A) Power generation, transmission,
and distribution installations, including related equipment for the purpose
of communication or metering, which
are accessible only to qualified employees;

(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: 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.)

NOTE 1: Work practices conforming to
§§ 1910.332 through 1910.335 of this part are
