3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
personal board-type sling equipment
Manually operated, non-powered personnel work equipment for descending along the facade of buildings or structures, designed for individual use and equipped with fall protection functionality.
Note: Consists of an anchor device, suspended descent system, and fall protection system.

anchor device
A device for securing the working line or flexible anchor line.
Note: Includes roof-mounted fixing frames, fixed (roof/ground) anchorage points, anchor points, counterweights, etc.
3.3
suspend decline system
A work system that allows the board to be lowered or fixed at any desired height along the working line via a manually controlled descender.
Note: Consists of a working line, descender, connector, and board-type working seat.
3.4
working line
A long rope fixed to the anchor device, laid along the work surface, on which the descender is installed, and which supports the weight of the user and carried equipment during work.
3.5
descender
A device installed on the working line, operated manually for controlled descent, using the working weight as the motive force.
Note: Common types of descenders are given in Appendix A.
3.6
connector
A component used for connecting and disconnecting different parts of the system.
