The storage tank either contains heated potable water or water supplied from an external source, such as a boiler. Indirect Waste Pipe. A pipe that does not connect directly to the drainage system but conveys liquid wastes by discharging into a plumbing fixture, interceptor, or receptacle that is directly connected to the drainage system. Individual Vent. A pipe installed to vent a fixture trap, and that connects with the vent system above the fixture served or terminates in the open air. Industrial Waste. Liquid or water-borne waste from industrial or commercial processes, except domestic sewage. Insanitary. A condition that is contrary to sanitary principles or is injurious to health.

Conditions to which “insanitary” shall apply include the following: (1) A trap that does not maintain a proper trap seal. (2) An opening in a drainage system, except where lawful

that is not provided with an approved liquid-sealed trap. (3) A plumbing fixture or other waste discharging receptor or

device that is not supplied with water sufficient to flush and maintain the fixture or receptor in a clean condition. (4) A defective fixture, trap, pipe, or fitting. (5) A trap, except where in this code exempted, directly con nected to a drainage system, the seal of which is not protected against siphonage and backpressure by a vent pipe. (6) A connection, cross-connection, construction, or condi tion, temporary or permanent that would permit or make possible by any means whatsoever for an unapproved foreign matter to enter a water distribution system used for domestic purposes.

(1) Faucets and Trim

a. Handwashing fixtures used by medical and nursing staff, patients, and food handlers shall have fittings such that all controls can be operated without the use of hands. i. Wrist or elbow blades shall be permitted unless otherwise noted in Table 4-2. ii. Blade handles used for this purpose shall be at least 4 inches (102 mm) in length. b. Sensor operated fixtures shall be capable of func- tioning during loss of normal power. c. Faucets shall not be equipped with an aerator but may be equipped with a non-aerating laminar flow device. d. Faucets shall be equipped with gooseneck spouts. A gooseneck spout shall be deck or fixture-mounted so the discharge point of the spout return is at least 10 inches (25.4 mm) above the bottom of the basin. The water shall not flow directly from the spout into the drain. The gooseneck spout shall have a 180 degree return with a constant radius and the outlet point- ing vertically down. e. Faucets shall be equipped with gooseneck spouts. A gooseneck spout is a deck or fixture-mounted spout so the discharge point of the spout return is at least 5 inches (127 mm) above the fixture rim. (2) Lavatory

not flow directly from the spout into the_ drain. The gooseneck spout shall have a 180 degree return with a constant radius and the outlet point- ing vertically down. e. Faucets shall be equipped with gooseneck spouts. A gooseneck spout is a deck or fixture-mounted spout so the discharge point of the spout return is at least 5 inches (127 mm) above the fixture rim. (2) Lavatory

a. Shall be designed and installed to prevent splashing outside of the lavatory. b. Shall be well-fitted and sealed to prevent water leaks onto or into the cabinetry or wall spaces. c. Design of lavatories and cabinetry shall not permit storage beneath the fixture basin. d. Shall be constructed of nonporous material. Hangers. See Supports. Health Care Facility’s Governing Body. The person or persons who have the overall legal responsibility for the operation of a health care facility. [NFPA 99:3.3.72] Heat-Fusion Weld Joints. A joint used in some thermoplastic systems to connect the pipe to fittings or pipe lengths directly to one another (butt-fusion). This method of joining pipe to fittings includes socket-fusion, electro-fusion, and saddle-fusion. This method of welding involves the application of heat and pressure to the components, allowing them to fuse together forming a bond between the pipe and fitting. High Hazard. See Contamination. Horizontal Branch. A drain pipe extending laterally from soil or waste stack or building drain with or without vertical sections or branches, which receives the discharge from one or more fixture drains and conducts it to the soil or waste stack or the building drain. Horizontal Pipe. A pipe or fitting that is installed in a horizontal position or which makes an angle of less than 45 degrees (0.79 rad) with the horizontal. Hot Water. Water at a temperature exceeding or equal to 120°F (49°C).
