Fall Arrest Factor of Safety

[McCarJ]

I have an anchor point that should be designed for 5000 Ibs as per OSHA , that will be based on factor of safety of 4. My question is, should i factor the 5000 Ibs or not ?, i found that some application factor it by 1.5.
Thanks

It is my understanding that this 5,000 load is already an 'ultimate' load, and is therefore factored.

They must 'sustain without breaking' a 5000 lbf load times the number of personal fall arrests attached at that anchor point. Ansi Z359.1 is a good place to go (it is industry written based on the Osha requirements).

In this area of work, Osha for the most part wants to see 4 to 1 on intended load. The 5000 lbf is not an intended load but the ultimate load it must withstand without failing.

Do you need a FS on the 5000 lbf? Well that depends on whether your anchor will be tested to hold the 5000 lbf as a minimum and how good you feel about your design.........

Read hard into this area of work as people's lives depend on what you do.
