(vi) Dead-end piping (risers with no flow, branches with no fixture) shall not be allowed. (B) Fire sprinkler systems. When provided, fire sprinkler systems shall comply with the requirements of NFPA 101, §9.7, Automatic Sprinklers and Other Extinguishing Equipment, and the requirements of this subparagraph. All fire sprinkler systems shall be designed, installed, and maintained in accordance with the requirements of NFPA 13, Standard for the Installation of Sprinkler Systems, 2002 Edition, and shall be certified as required by §131.147(c)(1)(C) of this title (relating to Construction, Inspection, and Approval of Project). (C) Piped nonflammable medical gas and clinical vacuum systems. Existing piped nonflammable medical gas and clinical vacuum systems shall be in accordance with NFPA 99, §5.1 for Level 1 Piped Systems. (D) Main storage of medical gases may be outside or inside the facility in accordance with NFPA 99, §5.1. Provision shall be made for additional separate storage of reserve gas cylinders necessary to complete at least one day's procedures. (2) Building sewers shall discharge into a community sewage system. Where such a system is not available, a facility providing sewage treatment shall conform to applicable local and state regulations. (3) Plumbing fixtures. Plumbing fixtures shall be made of nonabsorptive, acid-resistant materials and shall comply with the requirements of the National Standard Plumbing Code, and this paragraph. (A) Sink and lavatory controls. All lavatories used by medical and nursing staff and by patients shall be trimmed with valves or electronic controls which can be operated without the use of hands. Blade handles used for this purpose shall not be less than four inches in length. Single lever or wrist blade devices may also be used. (B) Back-flow or siphoning. All plumbing fixtures and equipment shall be designed and installed to prevent the back-flow or back-siphonage of any material into the water supply. The over-the-rim type water inlet shall be used wherever possible. Vacuum-breaking devices shall be properly installed when an over-the-rim type water inlet cannot be utilized. (C) Sterilizing equipment. All sterilizing equipment shall be designed and installed to prevent the contamination of the water supply, and the entrance of contaminating materials into the sterilizing units. (D) Hose attachment. No hose shall be affixed to any faucet if the end of the hose may become submerged in contaminated liquid unless the faucet is equipped with an approved, properly installed vacuum breaker. (E) Bedpan washers and sterilizers. When provided, bedpan washers and sterilizers shall be designed and installed so that both hot and cold water inlets shall be protected against back-siphonage at maximum water level. (F) Flood level rim clearance. The water supply spouts for lavatories and sinks required in patient care areas shall be mounted so that their discharge points are a minimum of five inches above the rim of the fixture. (G) Scrub sink controls. Freestanding scrub sinks and lavatories used for scrubbing in procedure rooms shall be trimmed with foot, knee, or electronic hands-free controls. Single lever wrist blades are not acceptable at scrub sinks. (H) Floor drains or floor sinks. Where floor drains or floor sinks are installed, they shall be of a type that can be easily cleaned by removal of the cover. Removable stainless steel mesh shall be provided in addition to a grilled drain cover to prevent entry of large particles of waste which might cause stoppages. (I) Under counter piping. Under counter piping and above floor drains shall be arranged (raised) so as not to interfere with cleaning of the floor below the equipment. (J) Ice machines. All ice-making machines used for human consumption shall be of the self-dispensing type. Copper tubing shall be provided for supply connections to ice machines. (i) General electrical requirements. This subsection contains common electrical and essential emergency system requirements. All electrical installation and equipment shall meet the requirements of the local building codes, ordinances and this subsection. (1) Electrical requirements. All electrical material and equipment, including conductors, controls, and signaling devices, shall be installed in compliance with applicable sections of the NFPA 70, National Electrical Code, 2002 Edition, §517; NFPA 99, Chapter 14; the requirements of this subsection; and as necessary to provide a complete electrical system.

Shielded isolation transformers, voltage regulators, filters, surge suppressors, and other safeguards shall be provided as required where power line disturbances are likely to affect fire alarm components, data processing, equipment used for treatment, and automated laboratory diagnostic equipment. (3) Services and switchboards. Main switchboards shall be located in separate rooms, separated from adjacent areas with one-hour fire-rated enclosures containing only electrical switchgear and distribution panels and shall be accessible to authorized persons only. These rooms shall be ventilated to provide an environment free of corrosive or explosive fumes and gases, or any flammable and combustible materials.
