Current through Register Vol. XLI, No. 28, July 12, 2024
All persons performing electrical work at construction
				  projects shall be certified by the State Fire Marshall or by the Department of
				  Mines.
32.1. General Requirements.
(a) All electrical work, installation, and
				wire capacities shall be in accordance with the pertinent provisions of the
				National Elec­trical Code, NFPA 70-1971; ANSI C1-1971 (Rev. of C1-1968)
				unless otherwise provided by these regulations.
(b) Applicability. These regulations apply
				only to electrical installations and used on the job site, both temporary and
				permanent. For power distribution and transmission lines, refer to subpart V of
				OSHA Safety and Health Regulations for Construction.
(c) Protection of employees.
(1) No employer shall permit an employee to
				work in such proximity to any part of an electric power circuit that he may
				contact the same in the course of his work unless the employee is protected
				against elec­tric shock by deenergizing the circuit and grounding it or
				by guarding it by effective insulation or other means. In work areas where the
				exact location of underground electric power lines is unknown, workmen using
				jackhammers, bars, or other hand tools which may contact a line shall be
				provided with insulated protective gloves.
(2) Before work is begun, the employer shall
				ascertain by inquiry or direct observation, or by instruments, whether any part
				of an electric power circuit, exposed, or concealed, is so located that the
				performance of the work may bring any person, tool, or machine into physical or
				electrical contact therewith. The employer shall post and main­tain
				proper warning signs where such a circuit exists. He shall advise his employees
				of the location of such lines, the hazards involved and the protective measures
				to be taken.
(d)
				Passageways and open spaces. Suitable barriers or other means shall be
				pro­vided to ensure that work space for electrical equipment will not be
				used as a passageway during periods when energized parts of electri­cal
				equipment are used.
(e) Work space
				around equipment. Sufficient space shall be provided and main­tained in
				the area of electrical equipment to permit ready and safe operation and
				mainte­nance of such equipment. When parts are exposed, the minimum
				clearance for the work space shall be not less than six and one-quarter (6 1/4)
				feet high, nor less than a radius of three (3) feet wide, and there shall be
				clear­ance sufficient to permit at least ninety de­grees (90)
				opening of all doors or hinged panels. All working clearances shall be
				main­tained in accordance with article 110-16, National Electrical Code,
				NFPA 70-1971; ANSI CI-1971 (Rev. of CI-1968).
(f) Load ratings. In existing
				installa­tion no changes in circuit protection shall be made to increase
				the load in excess of load rating of the circuit wiring, as specified in
				National Electrical Code, NFPA 70-1971; ANSI CI-1971 (Rev. of CI-1968) (Article
				310.)
(g) Lockout and tagging of
				circuits.
(1) Equipment or circuits that are
				deenergized shall be rendered inoperative and have tags attached at all points
				where such equipment or circuits can be energized.
(2) Tags shall be placed to identi­fy
				plainly the equipment or circuits being worked on.
(h) Ground-fault protection.
(1) General. Notwithstanding any other
				provision of this part, the require­ments in Section 210-7 of the 1971
				National Electrical Code (NFPA 70-1971; ANSI CI-1971), that all fifteen (15-)
				and twenty (20-) amphere receptacle outlets on single-­phase circuits
				for construction sites have approved ground-fault circuit protection for
				personnel does not apply. In lieu thereof, the employer shall use either
				ground-fault circuit interrupters or an assured equipment ground­ing
				conductor program to protect employees on construction sites. These
				requirements are in addition to any other requirements for equip­ment
				grounding conductors.
(2)
				Ground-fault circuit inter­rupters. All one hundred twenty (120) volt,
				single-phase, fifteen (15-) and twenty (20-) amphere 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 (2-) wire, single-phase portable or vehicle-mounted generator rated not
				more than five (5)kw, where the circuit conductors of the generator are
				insulated from the generator frame and all other grounded surfaces, need not be
				protected with ground-fault circuit inter­rupters.
(3) 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:
(i) 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 Director and any affected employee.
(ii) The employer shall designate one (1) or
				more competent persons to implement the program.
(iii) Each cord set, attach­ment cap,
				plug and recepta­cle of cord sets, and any equipment connected by cord
				and plug 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 may not be used
				until repaired.
(iv) The following
				tests shall be performed on all cord sets, 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:
(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.
(v) All required tests shall be
				performed:
(a) Before first use;
(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 six (6)
				months.
(vi) The
				employer may not make available or permit the use by employees of any equipment
				which has not met the re­quire­ments of this section.
(vii) Tests performed as required in this
				paragraph shall be recorded in a book approved by the Department of Mines. This
				test record shall identify each receptacle, cord set, and cord-and
				plug-connected equip­ment that passed the test, and shall indicate the
				last date it was tested or the interval for which it was tested. This record
				shall be kept by means of logs, color coding, or other effective means, and
				shall be maintained until replaced by a more current record. The record shall
				be made available on the job site for inspection by any affected
				employee.
