Does the Braille Need to be Below Tactile Letters?
On signs which designate permanent rooms and spaces, tactile characters must be accompanied by Grade 2 Braille, a series of contractions that forms a shorthand version of braille. Braille must be raised a minimum of 0.025" and a maximum of 0.037". Braille must be located below the corresponding text. If the text is more than one line, the braille can be located below the entire text. Also, there must be at least 3/8" between the braille and the nearest tactile characters.
Descriptions that accompany room numbers and room names do not have to have associated braille.
