SIDE WALL GRAB BAR AT WATER CLOSETS

ETA Editor's Note

At Hospital toilets and bathrooms used by patients, the 2013 California Electrical Code (2013 CEC) requires a nurse call device at the side wall of a water closet that must be coordinated carefully with the side grab bar at an accessible water closet to ensure that accessible clearances are met.  The following excerpts are from the 2013 CEC Errata dated January 1, 2014:

         517.123 [OSHPD 1, 2, 3 & 4] Call Systems.  Hospital signaling and nurse call equipment includes four types of call stations:  patient stations, bath stations, staff emergency stations, and code call stations.

                  (A) General.  ...

                  (B) Patient Stations.  ...

                  (C) Bath Stations.  A bath station that can be activated by a patient lying on the floor shall be provided at each room containing a patient water closet, bathtub, sitz bath, or shower stall. Pull cords shall extend to a maximum of 12 inches (30.48 centimeters) above the floor.

                           (1) An alarm in these areas shall be able to be turned off only at the bath station where it was initiated.

                                    Exception:  When two or more stations are located in the same bath area and all are visible from any call location, the alarm may be canceled at any of these locations.

                           (2) Bath stations in shower stalls and tubs shall be located 5 to 6 feet (1.52 to 1.83 meters) above the floor, within normal view of the user and within reach of staff without the need to step into the stall or tub.

                           (3) Bath stations shall be located to the side of toilets, within 12 inches (30.48 centimeters) of the front of the toilet bowl and 3 to 4 feet (.91 meter to 1.22 meters) above the floor. A bath station shall be permitted to serve both a toilet and a shower or other fixture if it is accessible to both.

                  (D) Staff Emergency Stations.  ...

                  (E) Code Call Stations.  ...

At 517.123(C)(3), the height of the nurse call device is not specified to be measured to the top of the box, as it is at 2013 CBC 11B-308.1.1 for electrical switches and 11B-308.1.2 for electrical receptacles.  It is recommended to install the nurse call device at/near the high limit of the allowable range, maintaining 12" minimum clearance above the top of the side grab bar, thus complying with 2013 CBC 11B-609.3.

Although the requirements of 2013 CEC 517.123 apply specifically to Hospitals and other facilities under OSHPD jurisdiction, it is not uncommon for nurse call devices to be installed at patient toilets in medical office buildings that are not under OSHPD jurisdiction.  In these, the positioning of the nurse call device is not strictly regulated by Code, but accessible clearances must be maintained from the grab bars at accessible water closets.

11B-604.5.2 Rear wall.

The rear wall grab bar shall be 36 inches (914 mm) long minimum and extend from the centerline of the water closet 12 inches (305 mm) minimum on one side and 24 inches (610 mm) minimum on the other side.

Exceptions:

1.      The rear grab bar shall be permitted to be 24 inches (610 mm) long minimum, centered on the water closet, where wall space does not permit a length of 36 inches (914 mm) minimum due to the location of a recessed fixture adjacent to the water closet.

2.      Where an administrative authority requires flush controls for flush valves to be located in a position that conflicts with the location of the rear grab bar, then the rear grab bar shall be permitted to be split or shifted to the open side of the toilet area.

ETA Editor's Note

The Office of Statewide Health Planning and Development (OSHPD), which has jurisdiction over hospitals and long-term care facilities in California, has issued Code Application Notice CAN 2-11B, dated 9/9/14, which includes the following interpretation of Subsection 11B-604.5.2:

CBC Section 1224.14.2.7 requires the provision of a flushing-rim clinical sink in the soiled utility room of a nursing unit.  There is an allowance to eliminate the clinical sink if facilities for cleaning bedpans are provided elsewhere.  CPC Table 4-2 Footnote 14 allows the clinical sink to be deleted if all bedrooms in the nursing unit are provided with adjoining toilets with bedpan flushing devices.

Patient toilet rooms with bedpan flushing devices are an allowance, not a requirement.  If this approach is pursued, the bedpan flushing device shall not be a unit that results in the need to split or offset the rear grab bar.  Section 11B-604.5.2 is not available to accommodate bedpan flushing devices.  The gripping surface of the grab bar must be available for the entire 36-inch length without interruption.

Bedpan washing devices that are manufactured as part of a flush valve assembly project above the rear grab bar, obstructing it.  OSHPD's interpretation disallows those at the water closets in accessible Patient Toilets.  There are wall-mounted bedpan washing devices that could be used instead, taking care not to obstruct either the side or the rear grab bars, or the required clear floor space.

 

Elevation drawing shows the rear grab bar 36 inches long minimum, positioned so that 24 inches minimum extends toward the open transfer side and 12 inches minimum extends toward the side wall.

REAR WALL GRAB BAR AT WATER CLOSETS

11B-604.6 Flush controls.

Flush controls shall be hand operated or automatic. Hand operated flush controls shall comply with Section 11B-309 except they shall be located 44 inches (1118 mm) maximum above the floor. Flush controls shall be located on the open side of the water closet except in ambulatory accessible compartments complying with Section 11B-604.8.2.

[2010 ADAS] 604.6 Flush Controls.  Flush controls shall be hand operated or automatic. Hand operated flush controls shall comply with 309. Flush controls shall be located on the open side of the water closet except in ambulatory accessible compartments complying with 604.8.2.

[2010 ADAS] Advisory 604.6 Flush Controls.  If plumbing valves are located directly behind the toilet seat, flush valves and related plumbing can cause injury or imbalance when a person leans back against them. To prevent causing injury or imbalance, the plumbing can be located behind walls or to the side of the toilet; or if approved by the local authority having jurisdiction, provide a toilet seat lid.

11B-604.7 Dispensers.

Toilet paper dispensers shall comply with Section 11B-309.4 _|Operation|_ and shall be 7 inches (178 mm) minimum and 9 inches (229 mm) maximum in front of the water closet measured to the centerline of the dispenser. The outlet of the dispenser shall be below the grab bar, 19 inches (483 mm) minimum above the finish floor and shall not be located behind grab bars. Dispensers shall not be of a type that controls delivery or that does not allow continuous paper flow. 

[S.H. 1115B.8.4]

[2010 ADAS] 604.7 Dispensers. Toilet paper dispensers shall comply with 309.4 and shall be 7 inches (180 mm)  minimum and 9 inches (230 mm)  maximum in front of the water closet measured to the centerline of the dispenser. The outlet of the dispenser shall be 15 inches (380 mm) minimum and 48 inches (1220 mm) maximum above the finish floor and shall not be located behind grab bars. Dispensers shall not be of a type that controls delivery or that does not allow continuous paper flow.

Elevation drawing shows the centerline of the toilet paper dispenser to be 7 to 9 inches in front of the water closet. The outlet of the dispenser is shown below the grab bar at 19" minimum above the floor.

This space cannot be obstructed by baby changing tables or other fixtures or conveniences, except as specified at 604.3.2 (Overlap). If toilet compartments are to be used to house fixtures other than those associated with the water closet, they must be designed to exceed the minimum space requirements. Convenience fixtures such as baby changing tables must also be accessible to people with disabilities as well as to other users. Toilet compartments that are designed to meet, and not exceed, the minimum space requirements may not provide adequate space for maneuvering into position at a baby changing table.
11B-604.8.1.1.1 Maneuvering space with in-swinging door.

In a wheelchair accessible compartment with an in-swinging door, a minimum 60 inches (1524 mm) wide by 36 inches (914 mm) deep maneuvering space shall be provided in front of the clearance required in Section 11B-604.8.1.1. See Figures 11B-604.8.1.1.2 (b) and 11B-604.8.1.1.3 (b).

MANEUVERING SPACE WITH END-OPENING DOOR

11B-604.8.1.2 Doors.

Toilet compartment doors, including door hardware, shall comply with Section 11B-404 except that if the approach is from the push side of the compartment door, clearance between the door side of the compartment and any obstruction shall be 48 inches (1219 mm) minimum measured perpendicular to the compartment door in its closed position. Doors shall be located in the front partition or in the side wall or partition farthest from the water closet. Where located in the front partition, the door opening shall be 4 inches (102 mm) maximum from the side wall or partition farthest from the water closet. Where located in the side wall or partition, the door opening shall be 4 inches (102 mm) maximum from the front partition. The door shall be self-closing. A door pull complying with Section 11B-404.2.7 shall be placed on both sides of the door near the latch.  Doors shall not swing into the clear floor space or clearance required for any fixture. Doors may swing into that portion of maneuvering space which does not overlap the clearance required at a water closet.

[2010 ADAS] 604.8.1.2 Doors.  Toilet compartment doors, including door hardware, shall comply with 404 except that if the approach is to the latch side of the compartment door, clearance between the door side of the compartment and any obstruction shall be 42 inches (1065 mm)  minimum. Doors shall be located in the front partition or in the side wall or partition farthest from the water closet.

Advisory 11B-604.8.1.2 Doors. This item describes requirements pertaining to the accessible water closet compartment door and the route to the door.

The door is required to have a latch which is flip-over style, sliding or which otherwise does not require the user to grasp or twist.  This is to facilitate latching the door by people with limited hand or finger dexterity.

The last part of this item addresses the required maneuvering space at the compartment door. This space is required to comply with requirements for door maneuvering space in Section 11B-404.2.4, except the space in front of the door shall be no less than 48 inches deep, measured perpendicular to the closed door. Where Figure 11B-404.2.4.1 (f) and  (j), specifically allow a 44” minimum maneuvering space perpendicular to doors in general in the closed position, a minimum of 48” must be provided in order to comply with Section 11B-604.8.1.2.

Note that in Figure 11B-404.2.4.1 (c) the front approach requires 12 inches of strike-side clearance on the push side where a door has both a latch and a closer.  However, the US Department of Justice has indicated that a self-closing compartment door with a gravity hinge is not considered to be a door with a closer; hence the 12-inch clearance would not be required in this type of design. ◼

ETA Editor's Note

For wheelchair accessible compartments with in-swinging doors, the compartment size required by CBC is nominally the same as required by 2010 ADAS.  For compartments with out-swinging doors, 2013 CBC requires larger compartments than 2010 ADAS due to the 48” minimum maneuvering space required in front of the water closet by 11B-604.8.1.1.3.

 

The compartment door is hinged 4 inches maximum from the side wall or partition farthest from the water closet so that the door opens on to the open transfer space. The minimum clearance between the door side of the stall and any obstruction is 42 inches.
Plan drawing of a wheelchair accessible compartment. The compartment door is hinged 4" maximum from the corner opposite the water closet. The compartment door swings out and is shown at the end of the stall with an alternate door location shown on the side of the compartment opposite the side wall with the grab bar.
