vi. to any object which is shaped or dimensioned such that the
snap hook or carabiner will not close and lock, or that roll-
out could occur
3. Do not pass the lanyard or lifeline through the roof anchor D-ring
and hook back into the lanyard or lifeline. When connecting,
make sure the connections are fully closed and locked.
4. When using an energy-absorbing lanyard, connect the energy
absorber "pack" end to the harness.
b. Anchorage strength
Depending on the application, the anchorage to which the anchor
is installed must meet strengths as given below:
1. FALL ARREST: Anchorages selected for personal fall arrest
systems (PFAS) shall have a strength capable of sustaining
static loads, applied in the directions permitted by the PFAS, of
at least; (A) 3,600 lbs. (16kN) when certiication exists (see ANSI
Z359.1 for certiication deinition), or (B) 5,000 lbs. (22kN) in the
absence of certiication. When more than one PFAS is attached
to an anchorage, the anchorage strengths set forth in (A) and
(B) above shall be multiplied by the number of personal fall
arrest systems attached to the anchorage. Per OSHA 1926.500
and 1910.66; Anchorages used for attachment of PFAS shall
be independent of any anchorage being used to support or
suspend platforms, and capable of supporting at least 5,000 lbs.
(22kN) per user attached, or be designed, installed, and used as
part of a complete PFAS which maintains a safety factory of at
least two, and is supervised by a qualiied person
2. WORK POSTITIONING: The structure to which the work
positioning system is attached must sustain static loads applied
in the directions permitted by the work positioning system of at
least 3,000 lbs., or twice the potential impact load, whichever
is greater. See OSHA 1926.502. When more than one work
positioning system is attached to an anchorage, the strengths
stated above must be multiplied by the number of work
positioning systems attached to the anchorage.
3. RESTRAINT: The structure to which the restraint system is
attached must sustain static loads applied in the directions
permitted by the restraint system of at least 3,000 lbs., or twice
the potential impact load, whichever is greater. See OSHA
1926.502. When more than one restraint system is attached to
