Wire rope safety factor for horizontal life line
Wire rope safety factor for horizontal life line
(OP)
I am designing a horizontal life line and OSHA says to use a minimum safety factor of 2 for the system. My question is what safety factor would be appropriate to use on the breaking strength of the wire rope? A typical SF of 5 which is used for slings and lifts seems to be high. Thanks. TCV

Frankly a factor of 5 sounds marginal.

RE: Wire rope safety factor for horizontal life line
When you say "horizontal lifeline", what is the application? (i.e., between two fixed anchor points with one or more people tied off to it. In which case, is it to keep them away from an edge or could it be loaded with impact when they actually fall off something?)

This is not a "proof is in the pudding" issue. Every lifeline used in the construction industry is designed for a factor of safety of 2. A factor of safety of 2 is both the codified value and standard practice.
