Door Closers [4.13.10]
Because it may be difficult for a person with a disability to open a door against the resistance offered by a closer, it is important that the closing action be slow enough to allow entry and exit. ADAAG requires that the sweep period of the closer be adjusted so that from an open position of 70 degrees, the door will take at least 3 seconds to move to a point 3 inches from the latch, measured to the leading edge of the door.
