method of using ropes, in combination with other devices, by which a user descends or ascends a working line to get to or from the workplace, and for work positioning, while further protected by a safety line, such that both lines are connected to the user’s harness and separately secured to a reliable anchorage in such a way that a fall is prevented or arrested, techniques by which access is gained to structures (e.g. buildings, radial dam gates, bridges, penstocks) and geologic features (e.g. cliffs, steep slopes) where ropes are the primary means of support, positioning, or safety protection
