Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) General. For purposes of this Section, a
						construction site is a place of employment where erection, demolition,
						alteration or excavation is being performed on a building, structure or
						underground facility, other than mining.
(b) Construction Sites. To protect employees
						on construction sites, the employer shall use either or both ground-fault
						circuit interrupters as specified in Subsection (c) of this Section or an
						assured equipment grounding conductor program as specified in Subsection (d) of
						this Section. These requirements are in addition to any other requirements for
						equipment grounding conductors.
(c)
						Ground-Fault Circuit Interrupters. All 120-volt, AC, single-phase, 15- and
						20-ampere receptacle outlets on construction sites, which are not a part of the
						permanent wiring of the building or structure and which are in use by
						employees, shall have approved ground-fault circuit interrupters for personnel
						protection. Receptacles on a two-wire, single phase portable or vehicle-mounted
						generator rated not more than 5 KW, where the circuit conductors of the
						generator are insulated from the generator frame and all their grounded
						surfaces, need not be protected with ground-fault circuit interrupters.
Feeders supplying 15- and 20-ampere receptacle branch
						  circuits shall be permitted to be protected by a ground-fault circuit
						  interrupter approved for the purpose in lieu of the above
						  provisions.
(d) Assured
						Equipment Grounding Conductor Program. The employer shall establish and
						implement an assured equipment grounding conductor program on construction
						sites covering all cord sets, receptacles which are not a part of the permanent
						wiring of the building or structure and equipment connected by cord and plug,
						which are available for use or used by employees. This program shall comply
						with the following minimum requirements:
(1) A
						written description of the program, including the specific procedures adopted
						by the employer shall be available at the job site for inspection and copying
						by the Division of Occupational Safety and Health and any affected
						employee.
(2) The employer shall
						designate one or more qualified persons as defined in Section
						2300 to implement the
						program.
(3) Each cord set,
						attachment cap, plug and receptacle of cord sets, and any equipment connected
						by cord and plug including these which are not required to be grounded, except
						cord sets and receptacles which are fixed and not exposed to damage, shall be
						visually inspected before each day's use for external defects, such as,
						deformed or missing pins or insulation damage, and for indication of possible
						internal damage. Equipment found damaged or defective shall not be used until
						repaired.
(4) The following tests
						shall be performed on all cord sets and receptacles which are not a part of the
						permanent wiring of the building or structure, and cord- and plug-connected
						equipment required to be grounded:
NOTE: Double-insulated tools or other similar equipment
						  are not required to be grounded. See Section
						  2395.45 Exception 2.
(A) All equipment grounding conductors shall
						be tested for continuity and shall be electrically continuous.
(B) Each receptacle and attachment cap or
						plug shall be tested for correct attachment of the equipment grounding
						conductor. The equipment grounding conductor shall be connected to its proper
						terminal.
(5) All tests
						required in Subsection (d)(4) shall be performed:
(A) Before first use for newly acquired
						equipment;
(B) Before equipment is
						returned to service following any repairs;
(C) Before equipment is used after any
						incident which can be reasonably suspected to have caused damage (for example,
						when a cord set is run over); and
(D) At intervals not to exceed three (3)
						months, except that cord sets and receptacles which are fixed and not exposed
						to damage shall be tested at intervals not exceeding 6
						months.
(6) The employer
						shall not make available or permit the use by employees of any equipment which
						has not met the requirements of Subsection (d) of this Section.
(7) Receptacles, cord sets and cord- and
						plug-connected equipment passing the tests required in Subsection (d) shall be
						identified. Identification may be made by means of logs, color coding or other
						effective means, shall be maintained until replaced by a more current
						identification, and shall indicate the last test date or the interval for which
						the tests were performed. These dates or intervals shall be readily available
						to the Division of Occupational Safety and Health and affected
						employees.
