Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Scope: This section covers the construction, operation,
						  and maintenance of electric power generation, control, transformation,
						  transmission, and distribution lines and equipment. This includes related
						  equipment for the purpose of communication or metering that are accessible only
						  to qualified employees.
(a) Hazard
						Assessment.
(1) The employer shall assess the
						workplace in accordance with GISO, Section
						3203 to identify employees exposed
						to hazards from flames or from electric arcs.
(2) For each employee exposed to hazards from
						electric arcs, the employer shall make a reasonable estimate of the incident
						heat energy to which the employee would be exposed.
NOTE 1 to subsection (a)(2): Appendix D to this article
						  provides guidance on estimating available heat energy. The Division of
						  Occupational Safety and Health will deem employers following the guidance in
						  Appendix D to this article to be in compliance with subsection (a)(2) of this
						  section. An employer may choose a method of calculating incident heat energy
						  not included in Appendix D to this article if the chosen method reasonably
						  predicts the incident energy to which the employee would be exposed.
NOTE 2 to subsection (a)(2): This subsection does not
						  require the employer to estimate the incident heat energy exposure for every
						  job task performed by each employee. The employer may make broad estimates that
						  cover multiple system areas provided the employer uses reasonable assumptions
						  about the energy-exposure distribution throughout the system and provided the
						  estimates represent the maximum employee exposure for those areas. For example,
						  the employer could estimate the heat energy just outside a substation feeding a
						  radial distribution system and use that estimate for all jobs performed on that
						  radial system.

						deenergized under the provisions of Section
						2940.14 and shall ensure proper
						grounding of the lines or equipment as specified in subsections (c) through (i)
						of this section. However, if the employer can demonstrate that installation of
						a ground is impracticable or that the conditions resulting from the
						installation of a ground would present greater hazards to employees than
						working without grounds, the lines and equipment may be treated as deenergized
						provided that the employer establishes that all of the following conditions
						apply:
(1) The employer ensures that the
						lines and equipment are deenergized under the provisions of Section
						2940.14.
(2) There is no possibility of contact with
						another energized source.
(3) The
						hazard of induced voltage is not present.

						transmission and distribution lines and equipment. It applies only to testing
						involving interim measurements using high voltage, high power, or combinations
						of high voltage and high power, and not to testing involving continuous
						measurements as in routine metering, relaying, and normal line work.
EXCEPTION to subsection (a): For the purposes of this
						  section, routine inspection and maintenance measurements made by qualified
						  employees shall be considered to be routine line work not included in the scope
						  of this section, provided that the hazards related to the use of intrinsic
						  high-voltage or high-power sources require only the normal precautions
						  associated with routine work specified in the other sections of the
						  High-Voltage Electrical Safety Orders. Two typical examples of such excluded
						  test work procedures are "phasing-out" testing and testing for a "no-voltage"
						  condition.
(b) General
						Requirements.
(1) Safe work practices. The
						employer shall establish and enforce work practices for the protection of each
						worker from the hazards of high-voltage or high-power testing at all test
						areas, temporary and permanent. Such work practices shall include, at a
						minimum, test area safeguarding, grounding, the safe use of measuring and
						control circuits, and a means providing for periodic safety checks of field
						test areas.
(2) Training. The
						employer shall ensure that each employee, upon initial assignment to the test

						  and on lines connected to capacitors.
(a) Before employees work on capacitors, the
						employer shall disconnect the capacitors from energized sources and short
						circuit the capacitors. A means shall be provided to reduce the residual
						voltage of a capacitor to 50 volts or less within 5 minutes after the capacitor
						is disconnected from the source of supply. The employer shall ensure that the
						employee short circuiting the capacitors waits at least 5 minutes from the time
						of disconnection before applying the short circuit.
(b) A discharge circuit shall be provided
						with automatic means of connecting it to the terminals of the capacitor bank
						after disconnection of the capacitor from the source of supply. The windings of
						motors, or transformers, or of other equipment directly connected to capacitors
						without a switch or overcurrent device interposed shall meet the requirements
						of subsection (a) above.
(c)
						Capacitors shall not be worked on until after they have been short circuited
						and grounded. The employer shall short circuit any line connected to capacitors
						before the line is treated as deenergized. The internal discharge device
						provided in capacitors shall not be used as a substitute for externally short
						circuiting and grounding capacitors.
(d) Before employees handle the units, the
						employer shall short circuit each unit in series-parallel capacitor banks
						between all terminals and the capacitor case or its rack. If the cases of
						capacitors are on ungrounded substation racks, the employer shall bond the
						racks to ground.

						spaces that may be entered by employees. It does not apply to vented vaults if
						the employer makes a determination that the ventilation system is operating to
						protect employees before they enter the space.
This section applies to routine entry into enclosed
						  spaces. If, after the employer takes the precautions given in this section and
						  in Section 2943, the hazards remaining in the
						  enclosed space endanger the life of an entrant or could interfere with an
						  entrant's escape from the space, then entry into the enclosed space shall meet
						  the permit space entry requirements of Article 37 of the Construction Safety
						  Orders or Section
						  5157 of the General Industry Safety
						  Orders.
NOTE to subsection (a): Entries into enclosed spaces
						  conducted in accordance with the permit space entry requirements of Article 37
