Details

All details must meet the following requirements: 1. Soap in a soap dispenser must be provided at all lavatories and sinks used by personnel for handwashing. 2. In new construction, boiler rooms must not be located under any portion of the facility. 3. Ceilings must be acoustically treated in corridors in resident areas, nurses stations, and dining and activity areas. 4. Noise reduction criteria shown in the following table apply to partition, floor, and ceiling assembly construction in resident areas: Airborne Sound Transmission Class (STC)* Impact Insulation Class (IIC)** Location Partitions Floors Floors Resident room to resident room 45 45 51 Public space to resident room *** 50 50 51+ Service areas to resident room ++ 55 55 55+ Footnotes: * Sound transmission class (STC) must be determined by tests in accordance with methods set forth in ASTM Standard E 90 and ASTM Standard E 413. ** Impact insulation class (IIC) must be determined in accordance with criteria set forth in HUD FT/TS 24. *** Public space includes lobbies, dining rooms, recreation rooms, treatment rooms, and similar spaces. + Impact noise limitation applicable only when corridor, public space, or service area is over resident's room. ++ Service areas include kitchens, elevators, elevator machine rooms, laundries, garages, maintenance rooms, boiler and mechanical equipment rooms, and similar spaces of high noise or vibration or both. Mechanical equipment located on the same floor or above or below the residents' rooms, offices, nurses' stations, and similar occupied spaces must be effectively isolated from such spaces with respect to noise and vibration. NOTE: The requirements set forth in this table assume installation methods which will not appreciably reduce the efficiency of the assembly as tested. Location of electrical receptacles, grilles, duct work, and other mechanical items, and blocking and sealing of partitions at floors and ceilings must not compromise the sound isolation required.
