Fall Arrest: From ANSI Z359.1; “The structure (mounting surface)
selected for personal fall arrest systems (PFAS) shall have a strength
capable of sustaining static loads in the direction(s) permitted by the
PFAS when in use of at least (A) 3,600 lbs. (16kN) when certification
exists (see ANSI Z359.1 for certification definition), or (B) 5,000 lbs.
(22.2kN) in absence of certification. When more than one tripod is
installed on a structure for fall arrest, and the systems will be used
simultaneously, the strengths set forth in (A) and (B) above shall be
multiplied by the number of systems attached to the structure.” From
OSHA 1926.500 and 1910.66; “Anchorages (mounting surface) used
for attachment of personal fall arrest systems (PFAS) shall be
independent of any anchorage being used to support or suspend
platforms, and capable of supporting at least 5,000 lbs. (22.2kN) per
user attached, or be designed, installed, and used as part of a
complete PFAS which maintains a safety factor of at least two and is
