projecting from walls (for example, telephones) with their leading edges
between 27 in and 80 in (685 mm and 2030 mm) above the finished floor shall
protrude no more than 4 in (100 mm) into walks, halls, corridors,
passageways, or aisles (see Fig. 8(a)). Objects mounted with their leading
edges at or below 27 in (685 mm) above the finished floor may protrude any
amount (see Fig. 8(a) and (b)). Free-standing objects mounted on posts or
pylons may overhang 12 in (305 mm) maximum from 27 in to 80 in (685 mm to
2030 mm) above the ground or finished floor (see Fig. 8(c) and (d)).
Protruding objects shall not reduce the clear width of an accessible route or
maneuvering space (see Fig. 8(e)). |

NOTE: In
Figure 8(a) two figures show the depth that objects are permitted to protrude
from walls based on their heights from the floor. In one figure the object is installed below
27 inches and is permitted to intrude into the “any amount” provided that
“clear width” is preserved. In the
other figure, the object is installed higher than 27 inches and cannot
protrude more than 4 inches from the wall.
Both figures show a person using a white cane avoiding the object by
making cane contact with sufficient stopping time. In Figure 8(b) a person using a white cane walks
perpendicular to an object with its leading edge at 27 inches above the floor
and detects the object with sufficient stopping time. In Figure 8(c) free-standing objects are shown
with their leading edges protruding no more than 12 inches from the floor. In Figure 8(c-1), the diagram illustrates (as an
example) a stair whose underside descends across a pathway. Where the
headroom is less than 80 inches, protection is offered by a railing (2030 mm)
which can be no higher than 27 inches (685 mm) to ensure detectability. In Figure 8(d), the diagram illustrates an area
where an overhang can be greater than 12 inches (305 mm) because the object
cannot be approached in the direction of the overhang. In Figure 8(e), the minimum clear width for
continuous passage is 36 inches. Thirty two (32) inches is the minimum clear
width for a maximum distance of 24 inches (610 mm). The maximum distance an
object can protrude beyond a wing wall is 4 inches (100 mm). |

308.2 Forward Reach. |
4.2.5 Forward
Reach. If the clear floor space only allows forward approach to an
object, the maximum high forward reach allowed shall be 48 in (1220 mm) (see
Fig. 5(a)). The minimum low forward reach is 15 in (380 mm). If the high
forward reach is over an obstruction, reach and clearances shall be as shown
in Fig. 5(b). NOTE: In
Figure 5(a), the forward reach range
shown in profile and plan view to be 48 inches maximum and 15 inches minimum. In Figure 5(b), the maximum
level forward reach over an obstruction with knee space below is 25 inches
(635 mm). When the obstruction is less than 20 inches (510 mm) deep, the
maximum high forward reach is 48 inches (1220 mm). When the obstruction
projects 20 to 25 inches (510 mm to 635 mm), the maximum high forward reach
is 44 inches (1120 mm). (4.2.5, 4.25.3). |

308.2.2 Obstructed High Reach. Where
a high forward reach is over an obstruction, the clear floor space shall
extend beneath the element for a distance not less than the required reach
depth over the obstruction. The high forward reach shall be 48 inches (1220
mm) maximum where the reach depth is 20 inches (510 mm) maximum. Where the

308.3 Side Reach. |
4.2.6 Side Reach. If
the clear floor space allows parallel approach by a person in a wheelchair,
the maximum high side reach allowed shall be 54 in (1370 mm) and the low side
reach shall be no less than 9 in (230 mm) above the floor (Fig. 6(a) and

shall be as shown in Fig 6(c). NOTE: In
Figure 6(a), the 30 by 48 inch clear floor
space is located a maximum 10 inches (255 mm) from the wall. In Figure 6(b), the 30 by 48 inch
wheelchair clear floor space is located a maximum 10 inches (255 mm) from the
wall. Figure 6(c) indicates that if the depth of the obstruction is
24 inches (610 mm) and the maximum height of the obstruction is 34 inches
(865 mm), the maximum high side reach over the obstruction is 46 inches
(1170). |
