The wiring of the emergency system shall be mechanically protected by installation in nonflexible metal raceways in accordance with NFPA 70, §517.30(C)(3). (8) Lighting. (A) Lighting intensity for staff and patient needs shall comply with guidelines for health care facilities set forth in the Illuminating Engineering Society of North America (IESNA) Handbook, 2000 edition, published by the IESNA, 120 Wall Street, Floor 17, New York, New York 10005. (i) Light intensity and wavelength control to prevent harm to the patient's eyes shall be considered. (ii) Approaches to buildings and parking lots, and all spaces within buildings shall have fixtures that can be illuminated as necessary. All rooms and spaces including storerooms, electrical and mechanical equipment rooms, and attics shall have sufficient artificial lighting for clear visibility. (iii) The special needs of the elderly shall be considered. The facility shall minimize excessive contrast in lighting levels that makes effective sight adaptation difficult. (B) Means of egress and exit sign lighting intensity shall comply with NFPA 101, §§7.8, 7.9, and 7.10. (C) Electric lamps, which may be subject to breakage or which are installed in fixtures in confined locations when near woodwork, paper, clothing, or other combustible materials, shall be protected by wire guards, or plastic shields. (D) Ceiling mounted surgical and examination light fixtures shall be suspended from rigid support structures mounted above the ceiling. (E) Trauma rooms/areas shall have general lighting in addition to local lighting provided by special lighting units at the procedure tables. Each fixed special lighting unit at the tables, except for portable units, shall be connected to an independent circuit. (F) X-ray film illuminators for handling at least two films simultaneously shall be provided in each trauma room/area and treatment room/area. When the entire emergency suite is provided with digital imaging system capabilities, a minimum of two X-ray film illuminator viewers shall be provided. The film illuminators shall be mounted within the central area of the emergency suite. (9) Receptacles. Only listed hospital grade single-grounding or duplex-grounding receptacles shall be used in the trauma, treatment, exam, diagnostic, imaging rooms, and all patient care areas. This does not apply to special purpose receptacles. (A) Installations of multiple-ganged receptacles shall not be permitted in all patient care areas. (B) Electrical outlets powered from the critical branch shall be provided in all patient care areas, diagnostic, imaging, procedure and treatment locations in accordance with NFPA 99, §4.4.2.2.2.3. At least one receptacle at each patient treatment or procedure location shall be powered from the normal power panel. All receptacles powered from the critical branch shall be colored red. (C) Replacement of malfunctioning receptacles and installation of new receptacles powered from the critical branch in existing facilities shall be replaced or installed with receptacles of the same distinct color as the existing receptacles. (D) All receptacles connected to the essential electrical system shall be identified. The face plate for the receptacle(s) shall have a nonremovable label or be engraved indicating the panel and circuit number. (E) In locations where mobile X-ray or other equipment requiring special electrical configuration is used, the additional receptacles shall be distinctively marked for the special use. (F) Each receptacle shall be grounded to the reference grounding point by means of a green insulated copper equipment grounding conductor in accordance with NFPA 70, §517-13. (G) Each treatment, examination, and trauma room in the emergency suite shall have a minimum of 6 duplex electrical receptacles located convenient to the head of each procedure table. All other walls shall have a minimum of at least 1 receptacle. (H) Each work table or counter shall have access to 1 duplex receptacle for every 6 feet of table or counter space or fraction thereof. Each work counter and table shall have at least 1 duplex receptacle connected to the critical branch of the emergency electrical system. (I) A minimum of one duplex receptacle in each wall shall be installed in each work area or room other than storage or lockers. (J) Appliances shall be grounded in accordance with NFPA 99, Chapter 9. (K) Ground fault circuit interrupters (GFCI) receptacles shall be provided for all general use receptacles located within 3 feet of a wash basin or sink. When GFCI receptacles are used, they shall be connected to not affect other devices connected to the circuit in the event of a trip. Receptacles connected to the critical branch used for equipment that should not be interrupted do not require GFCI protection. Receptacles in wet locations, as defined by NFPA 70, §§517.20 and 517.21, shall be GFCI protected regardless of the branch of the electrical system serving the receptacle. (10) Equipment.
