Check for Fall Proterction
Check for Fall Proterction
(OP)
I am new to this subject. Plant asking me to check if they can tie a worker fall protection to a non structural member?
Does anybody know what's the practice?
What load (what value) in what direction I need to apply to a non structural channel?
Any place that has information or an example? What has to be the Factor of Safety?
Any information appreciated. Never have check or design for such loads. Any impact loads need to be considered.
Thank you

Fall Protection Systems-- Certified Anchor / Non-Certified Anchor
Fall arrest-------------- 2 times max. arresting force / 5000 lb
Work positioning--------- 2 times foreseeable force / 3000 lb
Fall restraint----------- 2 times foreseeable force / 1000 lb
Rescue------------------- 5 time applied load / 3000 lb
Horizontal lifeline------ 2 times max. line load

1926.502(d)(15)
Anchorages used for attachment of personal fall arrest equipment shall be independent of any anchorage being used to support or suspend platforms and capable of supporting at least 5,000 pounds (22.2 kN) per employee attached, or shall be designed, installed, and used as follows:
1926.502(d)(15)(i)
as part of a complete personal fall arrest system which maintains a safety factor of at least two; and
1926.502(d)(15)(ii)
under the supervision of a qualified person.
1926.502(d)(16)
Personal fall arrest systems, when stopping a fall, shall:
1926.502(d)(16)(i)
limit maximum arresting force on an employee to 900 pounds (4 kN) when used with a body belt;
1926.502(d)(16)(ii)
limit maximum arresting force on an employee to 1,800 pounds (8 kN) when used with a body harness;

As for anchor strength...CSA standards (I don't recall which one right now) basically say the anchor point must be designed so that there is no permanent deformation at an applied load of 2500lbs and no failure at an applied load of 5000lbs. As noted above, you can design for 2xMAF (maximum arrest force), but this needs to be clearly understood by the user. Unless this is stated I think it is assumed the anchor is rated for 5000lbs.
