JUMP TO FULL CODE CHAPTER
Reference The Guidelines for other requirements.
Each patient sleeping room, except for special nursing care units or rooms, newborn nurseries and neonatal intensive care units or rooms, shall have a window(s) with a view, visible from the patient's bed, to the exterior of the building or to an atrium that is visually open to the exterior of the building. The clear opening of the patient room window's width and height shall have a minimum of 20 feet (6.10 m) unobstructed vista to any permanent structure or equipment, and a minimum of 15 feet (4.57 m) unobstructed vista to any vehicular parking area or to the property line measured horizontally from the plane of the window. The sill height of the window(s) shall be a maximum of 36 inches (0.914 m). Special nursing care units or rooms shall have a window(s) as required by this section and The Guidelines, except the sill height shall be a maximum of 60 inches (1.524 m).
Ceilings in patient care areas or rooms with ceiling-mounted surgical light fixtures, tracks, rails or pipes and in the centralized kitchens shall be a minimum height of 9 feet (2.7 m).
Toilet compartment partitions and urinal screens shall be constructed of products that do not rust, corrode or delaminate.
All fire walls, fire barriers, smoke barriers, horizontal exits and exit passageway partitions shall be constructed prior to the construction of all intervening walls. Where rated walls, barriers or partitions intersect, the continuity of the higher priority wall, barrier, or partition shall be maintained through the intersection.
Smoke barriers shall be constructed so as to provide a continuous smoke-tight membrane from exterior wall to exterior wall and from the floor to the underside of the floor or roof deck above. This includes interstitial space and the area above monolithic fire-rated ceiling membranes. Roof trusses shall be permitted to penetrate portions of the smoke barrier located above the fire-rated ceiling membrane where the annular space between the penetrating truss member and the smoke barrier is sealed to limit the transfer of smoke.
Where it is not possible to visually inspect a fire-rated partition, wall or barrier or a smoke barrier that extends through the attic or interstitial space to the roof or floor deck above because of the location of a monolithic ceiling membrane, ceiling access panel(s) shall be installed adjacent to each side of the partition, wall or barrier at intervals not exceeding 30 feet (9.00 m) and in such locations as necessary to view all surfaces of the partition, wall or barrier. Other ceiling access panels shall only be installed as required by other sections of the code. Partitions, walls and barriers requiring protected openings or penetrations shall be identified in accordance with Section 703 of this code.
Where electrical conduits, cable trays, ducts and utility pipes pass through the smoke barrier, the utilities shall be located so that access is maintained to adjacent wall surfaces and to all damper access panels. The details shall show the studs and reinforcing half studs so that proper support is provided for the wall surfacing material. There shall be a minimum clearance of 4 inches (102 mm) between all conduits, piping and duct work insulation that are located parallel or adjacent to a fire-rated wall or to a smoke barrier to facilitate the inspection of these walls.
The use of pocket sliding or folding doors to patient use toilet, baths, or shower rooms shall not be permitted. A sliding door equipped with sliding door hardware located on the patient room side of the wall and not equipped with a bottom door track shall be permitted.
A sliding door used to access an airborne infection isolation room or a protective environment room shall be equipped with an automatic closer that will close and latch when released.
The use of fire shutters to meet the requirements of opening protection required by other sections of this code shall not be permitted.
