| Determining Smoke Generation of Solid Materials, 2001 Edition, shall be provided. (C) Flooring shall be easy to clean and have wear resistance appropriate for the location involved. Floors that are subject to traffic while wet shall have a nonslip surface. In all areas frequently subject to wet cleaning methods, floor materials shall not be physically affected by germicidal and cleaning solutions. The following are acceptable floor finishes: (i) painted concrete for water treatment areas, mechanical, electrical, janitor's closets and general storage; (ii) exposed concrete shall be sealed for water treatment areas, mechanical, electrical, janitor's closets and general storage; (iii) vinyl sheets and vinyl composition tiles for offices, lobbies, administrative areas, storage, toilet rooms, treatment areas/rooms, isolation treatment room, exam rooms, training room, reprocessing rooms, support spaces and nontreatment areas; (iv) when monolithic or seamless flooring is installed it shall be impervious to water, coved and installed integral with the base, tightly sealed to the wall, and without voids that can harbor insects or retain dirt particles. The base shall not be less than six inches in height. Welded joint flooring is acceptable; (v) marble, ceramic and quarry tile for offices, lobbies, waiting, toilet rooms, administrative areas, wet areas, and similar spaces; (vi) carpet flooring for offices, administrative areas, and similar spaces; and (vii) terrazzo for offices, lobbies, administrative areas, and similar spaces. (D) Wall finishes shall be smooth, washable, moisture resistant, and cleanable. (i) Wall finishes shall be water-resistant in the immediate area of plumbing fixtures. (ii) Wall finishes subject to frequent wet cleaning methods shall be impervious to water, tightly sealed and without voids. (E) Ceilings which are a part of a rated roof/ceiling assembly or a floor/ceiling assembly shall be constructed of listed components and installed in accordance with the listing. Three types of ceilings that are required in various areas of the ESRD facility are: (i) ordinary ceilings are required in all areas or rooms in the ESRD facility unless a requirement requires a specific type of ceiling for such space. This includes ceilings such as acoustical tiles installed in a metal grid which are dry cleanable with equipment used in daily housekeeping activities such as dusters and vacuum cleaners; (ii) washable ceilings are ceilings that are made of washable, smooth, moisture impervious materials such as painted lay-in gypsum wallboard or vinyl faced acoustic tile in a metal grid when installed in the water treatment room and reuse room; (iii) monolithic ceilings which are monolithic from wall to wall (painted solid gypsum wallboard), smooth and without fissures, open joints, or crevices and with a washable and moisture impervious finish shall be provided for the isolation room and reuse room; and (iv) no finished ceiling is required in mechanical, electrical, general storage, and water treatment rooms. (F) Floor, wall and ceiling penetrations by pipes, ducts, and conduits, or any direct openings shall be tightly sealed to minimize entry of dirt particles, rodents and insects. Joints of structural elements shall be similarly sealed. (G) Materials known to produce noxious gases when burned shall not be used for mattresses, upholstery, and wall finishes. (H) A sign shall be posted at the entrance to each toilet/restroom to identify the facility for public, staff or patient use. (I) When vinyl sheets and vinyl composition tiles are used for toilet rooms, treatment areas/rooms, isolation treatment rooms, exam rooms, training rooms, and reprocessing rooms the joints shall be sealed to prevent moisture and blood from seeping into the joints and under the tile. (g) This subsection contains common requirements for mechanical systems; steam and hot and cold water systems; air conditioning, heating and ventilating systems; and thermal and acoustical insulation. (1) When mechanical equipment is exposed to weather, it shall be protected by weatherproof construction or weather protected. (2) Mechanical equipment shall be mounted on vibration isolators as required to prevent unacceptable structure-borne vibration. Ducts, pipes, etc. connected to mechanical equipment which is a source of vibration shall be isolated from the equipment with vibration isolators. (3) Prior to completion and acceptance of the facility, all mechanical systems shall be tested, balanced, and operated to demonstrate to the design engineer or his representative that the installation and performance of these systems conform to the requirements of the plans and specifications. (A) Upon acceptance of the mechanical system, the owner shall be provided with parts lists and procurement information with numbers and description for each piece of equipment. (B) Upon acceptance of the mechanical system, the owner shall be provided with instructions in the operational use of systems and equipment as required. (4) All heating, ventilating and air conditioning (HVAC) systems shall comply with and shall be installed in accordance with the requirements of National Fire Protection Association 90A, Standard for the Installation of Air Conditioning and Ventilating Systems, 2002 edition (NFPA 90A), NFPA 99, Chapter 6 and the requirements contained in this subsection. (5) All rooms and areas in the ESRD facility shall have provision for positive ventilation. Fans serving exhaust systems shall be located at the discharge end and shall be conveniently accessible for service. Exhaust systems may be combined, unless otherwise noted, for efficient use of recovery devices required for energy conservation. Supply air to the building and exhaust air from the building shall be regulated to provide a positive pressure within the building with respect to the exterior. (A) The systems serving all treatment areas/rooms, exam rooms, and isolation rooms, shall be capable of maintaining a temperature range between 68 and 78 degrees Fahrenheit and a relative humidity range between 45% and 60%. (B) The indoor design temperature in all other areas shall be between 68 and 75 degrees Fahrenheit with relative humidity of not less than 30%. (6) Ventilation systems for the reuse room and airborne isolation room shall be connected to an air exhaust system to the outdoors which is separate from the building exhaust system, have an exhaust fan located at the discharge end of the system, and have an exhaust duct system of noncombustible corrosion-resistant material as needed to meet the planned usage of the system. (A) The bottoms of wall-mounted return and exhaust air openings shall be at least six inches above the floor. All exhaust air openings and return air openings located higher than six inches but less than seven feet above the floor shall be protected with grilles or screens having openings through which a one-half inch sphere will not pass. (B) Exhaust outlets shall be above the roof level and arranged to minimize recirculation of exhaust air into the building. Exhaust outlets shall be located at least 25 feet from any fresh air intake of ventilating systems. (Prevailing winds and proximity to other structures may require more stringent requirements.) Plumbing and vacuum vents that terminate five feet above the level of the top of the air intake may be located as close as 10 feet. (C) If applicable, the reuse room and the airborne isolation room exhaust systems shall be connected to the emergency electrical system and shall meet the requirements of paragraph (10) of this subsection. (7) All toilet exhaust ventilation shall be exhausted to the outdoors. Exhaust systems may be combined, unless otherwise noted, for efficient use of recovery devices required for energy conservation. (8) To reduce utility costs, facility design may utilize energy conserving procedures including recovery devices, variable air volume, load shedding, systems shutdown, or reduction of ventilation rates (when specifically permitted) in certain areas when unoccupied. In no case shall patient care be jeopardized. (9) Mechanical systems shall be arranged to take advantage of outside air conditions by using an economizer cycle when appropriate to reduce heating and cooling systems loads. Innovative design that provides for additional energy conservation while meeting the intent of this subsection for acceptable patient care may be presented to the department for consideration. (10) Outside air intakes shall be located at least 25 feet from exhaust outlets of ventilating systems, combustion equipment stacks, plumbing vents, or areas which may collect vehicular exhaust or other noxious fumes. (Prevailing winds and proximity to other structures may require more stringent requirements). Plumbing vents that terminate five feet above the level of the top of the air intake may be located as close as 10 feet. Cont'd... |
