The correct ADA hand dryer
installation may not need a recessed hand dryer depending on where it is
installed. Read the ADAAG (The Americans with Disabilities Act
Accessibility Guidelines) Issued by Architectural and Transportation
Barriers Compliance Board and consult with your local inspector.
Local code varies greatly so interpretation and county or city codes
will very.
Always get approval of your local
inspectors.
Local inspectors may allow hand
dryers to protrude from the wall more than for 4" if they are not
installed "into walks, halls, corridors, passageways, or aisles" where
they would be undetectable by persons using canes or trained service
animals walking. Installing a surface mounted hand dryer on walls
that are a protrusion hazard could be allowable. Suggested areas
are next to sinks or on walls not along walk paths.
4.4 Protruding
Objects
http://www.access-board.gov/adaag/html/adaag.htm#4.4
4.4.1* General. Objects 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)).
Appendix Note
A4.4 Protruding Objects.
A4.4.1 General. Service animals are trained to recognize and avoid
hazards. However, most people with severe impairments of vision use the
long cane as an aid to mobility. The two principal cane techniques are
the touch technique, where the cane arcs from side to side and touches
points outside both shoulders; and the diagonal technique, where the
cane is held in a stationary position diagonally across the body with
the cane tip touching or just above the ground at a point outside one
shoulder and the handle or grip extending to a point outside the other
shoulder. The touch technique is used primarily in uncontrolled areas,
while the diagonal technique is used primarily in certain limited,
controlled, and familiar environments. Cane users are often trained to
use both techniques.
Potential hazardous objects are
noticed only if they fall within the detection range of canes (see
Fig.
A4). Visually impaired people walking toward an object can detect an
overhang if its lowest surface is not higher than 27 in (685 mm). When
walking alongside protruding objects, they cannot detect overhangs.
Since proper cane and service animal techniques keep people away from
the edge of a path or from walls, a slight overhang of no more than 4 in
(100 mm) is not hazardous.
