A suspended scaffold is a working platform that:
Is suspended by ropes from overhead outriggers, needles, parapet hooks or brackets fixed to a building or structure.
Is capable of being raised and lowered by hand haulage on fiber ropes, or by hoists that are either manually or mechanically operated using wire ropes.
2013-3-28 References: 18


Scaffold area
The horizontal length of a scaffold in meters times the average height of the scaffold will give the scaffold area in square meters. So:
Length (m) x Average Height (m) = Area (m 2 )
The height of the scaffold may be taken from of the height of the topworking platform or alternatively from the top guardrail.
