Section R308.4 #10 and 11
10.
Glazing adjacent to stairways, landings and ramps within 36 inches (914 mm) horizontally of a walking surface when the exposed surface of the glass is less than 60 inches (1524 mm) above the plane of the adjacent walking surface.
11.
Glazing adjacent to stairways within 60 inches (1524 mm) horizontally of the bottom tread of a stairway in any direction when the exposed surface of the glass is less than 60 inches (1524 mm) above the nose of the tread.
What range do you consider to be hazardous at the top of stairs? A 36" x 36" landing is required at the top of stairs, so does that mean an additional 36" from the landing is in the hazardous range? 72" perpendicular from the top tread?!
#11 clearly depicts the horizontal distance from the bottom tread, but doesn't address the top.
Your interpretation please
