Okla. Admin. Code § 310:615-5-10

Current through Vol. 42, No. 7, December 16, 2024

Section 310:615-5-10 - Electrical requirements

(a)General.

(1) All material, including equipment, conductors, controls, and signaling devices, shall be installed to provide a complete electrical system with, the necessary characteristics and capacity to supply the electrical facilities shown in the specifications or indicated on the plans. All materials shall be listed as complying with available standards of Underwriters' Laboratories, Inc., or other similarly established standards.

(2) All electrical installations and systems shall be tested to show that the equipment is installed and operates as planned or specified. A written record of performance tests on special electrical systems and equipment shall be supplied to the owner. Such tests shall show compliance with the governing codes and shall include conductive floors, isolated power systems, grounding continuity, and alarm systems.

(b)Switchboards and power panels. Circuit breakers or fusible switches that provide disconnecting means and over current protection for conductors connected to switchboards and panel boards shall be enclosed or guarded to provide a dead-front type of assembly. The main switchboard shall be located in a separate enclosure accessible only to authorized persons. The switchboards shall be convenient for use, readily accessible for maintenance, clear of traffic lanes, and in a dry, ventilated space free of corrosive fumes or gases. Overload protective devices shall be suitable for operating properly in the ambient temperature conditions.

(c)Panel boards. Panel boards serving lighting and appliance circuits shall be located on the same floor as the circuits they serve.

(d)Lighting.

(1) All spaces occupied by people, machinery, and equipment within buildings, approaches to buildings, and parking lots shall have lighting.

(2) Operating rooms shall have general lighting in addition to local lighting provided by special lighting units at the surgical tables. Each fixed special lighting unit at the tables, except for portable units, shall be connected to an independent circuit.

(e)Receptacles (convenience outlets).

(1)Anesthetizing locations. Each operating room shall have at least three receptacles of the types described in NFPA Standard 56A. In locations where mobile X-ray is used, an additional receptacle, distinctively marked for X-ray use, shall be provided. Where capacitive discharge or battery-powered X-ray units are used, these receptacles will not be required.

(2)Rooms other than anesthetizing locations. Duplex-grounding type receptacles shall be installed in all areas in sufficient quantities for the tasks to be performed. A minimum of one duplex receptacle for each wall shall be installed in each work area or room other than storage or lockers. Each examination and work table shall have access to a minimum of two duplex receptacles.

(3)Corridors. Duplex receptacles for cleaning equipment and general use shall be installed approximately 50'-0Prime; apart in all corridors and within 25'-0Prime; of ends of corridors.

(f)Equipment installation in special areas.

(1)Installation in anesthetizing locations. All electrical equipment and devices, receptacles, wiring, and conductive flooring, if used, shall comply with NFPA Standard 56A, except that a static-type line-isolation monitor will be permitted.

(2)X-ray installations. Fixed and mobile X-ray equipment installations shall conform to Article 660 of NFPA Standard 70.

(3)Special grounding system. In areas (when indicated by the program) where a patient may be treated with an internal probe or catheter connected to the heart, the patient-bed area ground system shall comply will the following:

(A) A patient ground point shall be provided within 10'-0Prime; of each bed. The patient ground is to assure that under normal conditions all electrically conductive surfaces of equipment and furnishings within reach of the patient will be at the same electrical potential or not exceeding ten millivolts differential. This requirement is not intended to apply to devices and utensils such as bedpans and other small portable non-electrical devices.

(B) One patient ground point may serve more than one patient, but one patient shall not be served by more than one patient ground point.

(C) The grounding conductor connecting any receptacle serving a patient and-the patient ground point shall not exceed the equivalent resistance of 15'-OPrime; of No. 12 AWG copper conductor.

(D) Exposed metal-building surfaces or utility piping within reach of the patient or others who may touch him shall be grounded at the patient ground point or to another room ground point.

(E) A reference ground point shall be established in the electrical supply panel.

(F) The patient ground point and the room ground point where separated shall be interconnected by a continuous, insulated, copper conductor not smaller than No. 10 AWG and similarly connected to the reference ground or may be individually connected to the reference ground point provided that the ground conductor resistance does not exceed that of 15'-0Prime; or No. 12 AWG copper conductor.

(G) Receptacle ground terminals shall be connected to the patient ground point or to the reference ground point provided that grounding conductor resistance to the reference ground point does not exceed that of 15'-0Prime; of No. 12 AWG copper conductor.

(H) Grounding of all metallic raceways shall be by means of grounding bushings on all conduit terminations at the panel board and by means of an insulated, continuous, stranded, copper grounding conductor, not smaller than No. 12 AWG extended from the grounding bus in the panel board to the conduit grounding bushings.

(I) Grounding of metallic switch and receptacle plates shall be provided by means of the mounting-screw connections to the device mounting yokes.

(g)Emergency lighting. Automatic emergency lighting shall be provided in each operating room, each recovery room and in ways of exits to make egress from the building safer in the event of power failure.

(h)Fire alarm systems. A manually operated electrically supervised fire-alarm system shall be installed in each facility that has a total floor area of more than 5,000 square feet.

(i)Emergency power requirements.

(1) Ambulatory surgical centers that allow inhalation anesthetics administered in any concentration, or if patients require electrical life-support equipment, shall provide electrical services conforming to Type I System, NFPA 99, Chapter 13.

(2) Ambulatory surgical centers that do not administer inhalation anesthetics in any concentration, or have no patients requiring electrical life support equipment, shall be permitted to use a battery system or self-contained battery integral with equipment, conforming to the Type III System, NFPA 99, Chapter 13.
