Rule 1722.
(1)
					 The employer shall establish and implement an assured equipment grounding
					 conductor program for construction operations. The program shall cover all
					 extension cords, 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.
(2) This program shall comply with the
					 following minimum requirements:

					 description of the program, including the specific procedures adopted by the
					 employer, shall be available at the jobsite for inspection and copying by the
					 director, department representative, and any affected employee.
(b) The employer shall designate 1 or more
					 competent persons to implement the program.
(c) Each extension cord, attachment cap, plug
					 and receptacle of cord sets, and any equipment connected by cord and plug,
					 except extension cords 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 indications of
					 possible internal damage. Equipment found damaged or defective shall not be
					 used until repaired.
(d) The
					 following tests shall be performed on all extension cords, 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:
(i) All equipment grounding conductors shall
					 be tested for electrical continuity.
(ii) 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.
(e) All
					 required tests shall be performed at the following time:
(i) Before first use.
(ii) Before equipment is returned to service
					 following any repairs.
(iii) Before
					 equipment is used after any incident which can be reasonably suspected to have
					 caused damage, for example, when an extension cord is run over.
(iv) At intervals not exceeding 3 months,
					 except that extension cords and receptacles which are fixed and not exposed to
					 damage shall be tested at intervals not exceeding 6 months.
(f) The employer shall not make
					 available, or permit the use by employees of, any equipment which does not meet
					 the requirements of this rule.
(g)
					 Tests performed as required in this rule shall be recorded. The test record
					 shall identify each receptacle, extension cord, 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 at the
					 jobsite for inspection by the director, department representative, and any
					 affected employee.
