4 Safety requirements
4.1 Design and ergonomics
4.1.1 It shall not be possible for a LSD to become detached unintentionally. If any part can be opened
or removed, it shall be designed such that it can only be done after performing at least 3 separate,
consecutive and deliberate manual actions or by the use of a tool.
4.1.2 Where a LSD includes more than one element and for an LSD with elements that can be
adjusted, the design shall be such that those elements cannot appear to be positively locked together
when they are incorrectly assembled or adjusted.
4.1.3 Where a LSD includes another function (connector, rope clamp, etc.) it shall also comply to the
appropriate other applicable text/standard, if existing.
4.1.4 Where stitching is used to provide safety and strength (e.g. in joints) it shall be possible to
inspect it and at least 50 % of the stitching shall contrast with the textile element in colour or surface
appearance.
4.1.5 All edges of a LSD shall be free of burrs and sharp edges.
The internal edges of the hole(s) shall be rounded with a radius larger than 0,2 mm or have a chamfer
larger than 0,2 mm × 45° (see a) in Figure 2).
