Rules for Tactile Signs
Raised letters and numbers are provided on signs so that people who cannot read Braille, but who do have a clear image of the shapes of letters and numbers, can identify rooms. Only the identifying words or numbers need to be tactile. For instance, a dental office might have the number one hundred twenty and also have other information, such as the name of the dentist and the hours of operation. Only the number would need to be tactile.
|
The raised characters should be raised at least one thirty-second inch from the surface. They should be very simple in shape so they are easy to read by touch and all letters must be uppercase, or capital letters. The size must range from five eighths to two inches high.
|
For those who use their vision, the characters must not be shiny or reflective, and the background of the sign behind the text must also be non-glare. The characters must have a high contrast to the background, light on dark or dark on light. Although no specific value is mandated, one suggestion is a minimum contrast of 70 percent.
|
The only requirement for the Braille translation is that it must be Grade 2 Braille. Because there are no other specifications for sign makers to follow, this has resulted in Braille on signs which is sometimes very difficult to read and is often located at awkward places on the sign in relationship to the raised characters.
|
Tactile signs must be mounted beside the door they identify. If possible, they should be mounted on the latch, or strike side of the door, so they will not be hidden if the door is open. The sign is to be mounted so that its center is sixty inches from the floor, or about average eye level, and it should be located so that you won't get hit by the door opening suddenly if you are standing very close to read the sign.
