The employer shall ensure at a construction site of a building or other construction work that every suspended scaffold, raised or lowered by the winches or climbers, is provided at each of its suspension point with a safety rope with such automatic safety device mounted on each of such rope so that such safety rope with each automatic safety device supports the platform of such scaffold in the event of failure of primary suspension wire ropes, winches, climbers or any part of the mechanism used for raising or lowering such suspended scaffold:
Provided that this rule shall not apply—
(a) where the platform of such scaffold is supported at two independent suspension wire ropes at or near each end of such platform so that in the event of failure of one of such suspension wire ropes, the other wire rope is capable of sustaining the weights of such platform and its load and prevents it from tilting; or
(b) where a system is incorporated, which operates automatically to support the platform of such scaffold and its load in the event of failure of the primary suspension wire rope of such scaffold.
