Sorry, I didn't check back earlier and see this great article. Thanks, Mark! Maybe I can include it in some way when I get those incorrect requirements for "To Exit" signs! I can see that, in some schools, we should have probably been using the "To Exit" signs instead of "Exit Route" signs at some doors, but again, since they are really information for people who are blind, and the visual signs don't make a distinction, I still think we should just have the "Exit Route" signs.
As to Wayne's question: Blind people "in the know" are supposed to be looking for readable tactile signs adjacent to doors. For restrooms in a restaurant, for instance, they would act like most of us do, and ask someone to point them toward the restrooms. They are usually in a small alcove or corridor, through a door or doorway. In an office building with public restrooms in corridors, they would ask the direction. Once they get to the approximate location, they would feel alongside the door, and hope to find a tactile sign.
The problem has been that there are so few venues that have bothered with the signs, or if they have the signs, they are unreadable, or in the wrong location, that many savvy blind people have just given up on them. And they don't sue, because they have been told that it hasn't actually harmed them, as long as someone has been able to show them the restroom.
Actually, we should take this thread by now over to the ADA section!
Thanks, both Wayne and Mark for responding. And let's work to simplify the tactile exit sign messages!
