There are two basic types of
Braille, the first is called Grade 1 Braille. This Braille is
a letter for letter translation and should only be used by those
that already understand braille well enough to translate the
text themselves. The second type which has become the standard
for sign making is Grade 2 Braille.
This Braille consists of abbreviations
and conjunctions that are generally accepted.
Where there is no wall space
to the latch side of the door, signs shall be placed on the nearest
adjacent wall, mounting height shall be 60 inches above the floor
to the centerline of the sign, mount signs so that
a person may approach 3 inches
of signage without encountering protruding objects or standing
the swing of a door.
