(vi) Verification test requirements. Verification tests of the medical gas piping system and the warning system shall be performed on all new piped medical gas systems, additions, renovations, or repaired portions of an existing system. All systems that are breached and components that are added, renovated, or replaced shall be inspected and appropriately tested. The breached portions of the systems subject to inspection and testing shall be all of the new and existing components in the immediate zone or area located upstream of the point or area of intrusion and downstream to the end of the system or a properly installed isolation valve. (vii) Warning system verification tests. Verification tests of piped medical gas systems shall include tests of the source alarms and monitoring safeguards, master alarm systems, and the area alarm systems. (viii) Source equipment verification tests. Source equipment verification tests shall include medical gas supply sources (bulk and manifold) and the compressed air source systems (compressors, dryers, filters, and regulators). (ix) ASC responsibility. Before new piped medical gas systems, additions, renovations, or repaired portions of an existing system are put into use, ASC medical personnel shall be responsible for ensuring that the gas delivered at the outlet is the gas shown on the outlet label and that the proper connecting fittings are checked against their labels. (x) Written certification. Upon successful completion of all verification tests, written certification for affected piped medical gas systems and piped medical vacuum systems including the supply sources and warning systems shall be provided by a party technically competent and experienced in the field of medical gas pipeline testing stating that the provisions of NFPA 99 have been adhered to and systems integrity has been achieved. The written certification shall be submitted directly to the ASC and the installer. A copy shall be available at final department construction inspection. (xi) Documentation of medical gas and clinical vacuum outlets. Documentation of the installed, modified, extended or repaired medical gas piping system shall be submitted to the department by the same party certifying the piped medical gas systems. The number and type of medical gas outlets (e.g., oxygen, vacuum, medical air, nitrogen, nitrous oxide) shall be documented and arranged tabularly by room numbers and room types. (D) Medical gas storage facilities. Main storage of medical gases may be outside or inside the ASC 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. (E) Multiple gas outlets on one medical gas outlet. Y-connections, "twinning", or other similar devices shall not be used on any medical gas outlet. (F) Waste anesthetic gas disposal (WAGD) systems. Each space routinely used for administering inhalation anesthesia shall be provided with a WAGD system as required by NFPA 99, §5.1.3.7. (2) Steam and hot water systems. (A) Boilers. When provided, the boilers shall have the capacity, based upon the net ratings as published in The I-B-R Ratings Book for Boilers, Baseboard Radiation and Finned Tube (commercial) by the Hydronics Institute Division of GAMA, to supply the normal heating, hot water, and steam requirements of all systems and equipment. The document published by the Hydronics Institute Division of GAMA as referenced in this rule may be obtained by writing or calling the Hydronics Institute Division of GAMA at 35 Russo Place, Post Office Box 218, Berkeley Heights, New Jersey 07922, telephone (908) 464-8200. (i) Boiler accessories. Boiler feed pumps, heating circulating pumps, condensate return pumps, and fuel oil pumps shall be connected and installed to provide normal and standby service. (ii) Valves. Supply and return mains and risers of cooling, heating, and process steam systems shall be valved to isolate the various sections of each system. Each piece of equipment shall be valved at the supply and return ends except that vacuum condensate returns need not be valved at each piece of equipment. (B) Boiler certification. When required, the ASC shall ensure compliance with Texas Department of Licensing and Regulation, Boiler Section, Texas Boiler Law, (Health and Safety Code, Chapter 755, Boilers), which requires certification documentation for boilers to be posted on site at each boiler installation. (3) Drainage systems. 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. (A) Above ground piping. Soil stacks and roof drains installed above ground within buildings shall be drain-waste-vent (DWV) weight or heavier and shall be: copper pipe, copper tube, cast iron pipe, or Schedule 40 polyvinyl chloride (PVC) pipe. Buildings or portions of buildings remodeled to an ASC need not comply with this requirement. (B) Underground piping. All underground building drains shall be cast iron soil pipe, hard temper copper tube (DWV or heavier), acrylonitrile-butodiene-styrene (ABS) plastic pipe (DWV Schedule 40 or heavier), or PVC pipe (DWV Schedule 40 or heavier. Underground piping shall have at least 12 inches of earth cover or comply with local codes. Existing buildings or portions of buildings that are being remodeled need not comply with this subparagraph. (C) Drains for chemical wastes. Separate drainage systems for chemical wastes (acids and other corrosive materials) shall be provided. Materials acceptable for chemical waste drainage systems shall include chemically resistant borosilicate glass pipe, high silicone content cast iron pipe, polypropylene plastic pipe, or plastic lined pipe. (D) Drainage and waste piping. Drainage and waste piping shall not be installed above or below ceilings in operating rooms, special procedure rooms, and sterile processing rooms unless precautions are taken to protect the space below from leakage and condensation from necessary overhead piping. Secondary protection shall be required to drain. Any required secondary protection shall be labeled, "code required secondary drain system" every 20 feet in a highly visible print or label. (4) Thermal insulation for piping systems and equipment. Asbestos containing insulation materials shall not be used. (A) Insulation. Insulation shall be provided for the following: (i) boilers, smoke breeching, and stacks; (ii) steam supply and condensate return piping; (iii) hot water piping and all hot water heaters, generators, converters, and storage tanks; (iv) chilled water, refrigerant, other process piping, equipment operating with fluid temperatures below ambient dew point, and water supply and drainage piping on which condensation may occur. Insulation on cold surfaces shall include an exterior vapor barrier; and (v) other piping, ducts, and equipment as necessary to maintain the efficiency of the system. (B) Insulation flame spread. Flame spread shall not exceed 25 and smoke development rating shall not exceed 50 for pipe insulation as determined by an independent testing laboratory in accordance with NFPA 255, Standard Method of Test of Surface Burning Characteristics of Building Materials, 2000 Edition. (5) 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.
