Lighting
A. The safety of visitors (particularly those with low vision and visual perceptual difficulties)
must receive equal consideration with exhibit design and conservation issues.
B. Light and color must combine to produce a clearly delineated circulation route into,
through, and out of every exhibition space. This is a particular requirement whenever
there are changes in level or unexpected turns or obstacles in the route.
C. There must be sufficient light on objects to make them visible to all visitors unless the
light level will do substantial damage to the objects.
D. There must be sufficient light on labels to make them readable by all visitors.
E. The elimination of glare from cases and on labels must be considered for those visitors
who are seated as well as for those who are standing.
F. Sufficient light to accommodate speechreading and sign language conversation must be
provided in locations throughout the exhibition space.
IX. Public Programming Spaces
A. In places of assembly with fixed seating, there must be a number of wheelchair
locations provided in compliance with the requirements of the Smithsonian Guidelines
for Accessible Design for Facilities and Sites. These locations must be dispersed
throughout the seating area.
B. If seating is in the form of benches, the same number of benches with arm and back
support as wheelchair locations required in the Smithsonian Guidelines for Accessible
Design for Facilities and Sites must be provided.
C. Where there is fixed seating, there must also be aisle seats (one percent of the total
number, with no fewer than one) that have no armrests, swing-away armrests, or
