OPEN SIDES AND ENDS - The edges of a scaffold platform that exceed the maximum

allowable horizontal distance away from a sturdy, continuous vertical surface (such as a building

wall) or a sturdy, continuous surface (such as a floor). This is normally a distance of 14- to 16-

inches, but may be greater or lesser depending upon the type of work to be performed on the

platform and the particular safety standard under which the work is being performed.
