OSHA requirements for a safety factor of
two, such as an I-beam or other support
structure. An anchorage connector, such
as the cross-arm strap, D-bolt or rebar hook
anchor, is sometimes necessary to make
a compatible connection between the
connecting device and the anchorage.
B) BODY WEAR
Body wear is a personal protective gear
worn by the worker while performing the
job. The only form of body wear acceptable
for fall arrest is the full-body harness.
It is imperative that the harness be worn
properly. Visually check all buckles to ensure
proper and secure connections before
each use. All straps must be connected and
adjusted to provide a snug fit.
Fall
protection
should be attached to the back D-ring
of the full-body harness. A sternal D-ring
attachment element may be used for fall
arrest only in rescue, work positioning,
rope access, and other recognized applica-
tions where the personal fall arrest system
limits the maximum free fall distance to 2
ft (0.6m) and limits the maximum arrest
force to 1800 lb (8kN).
Side and sternal D-rings should be used
for positioning only. (Note front D-ring
exception
above.);
should be used for retrieval, raising or
lowering only.
Never attach rebar (pelican) hooks to a
harness D-ring. Body belts should be used
for positioning and restraint only.
C) CONNECTING DEVICE
Connecting device is the critical link which
joins the body wear to the anchorage/
anchorage connector. The most important
feature of the connecting device is the
built-in shock absorber. Whether the
connecting device is a shock-absorbing
lanyard or Self-Retracting Lifelines, they
are designed to dramatically reduce
fall arrest forces. Rope, web or wire rope
lifelines being used for fall arrest MUST be
used in conjunction with a shock absorber
(i.e., Miller SofStop pack).
Individually, none of these components
will provide protection from a fall. However,
when used properly and in conjunction
with each other, they form a Personal
Fall Arrest System that becomes vitally
important to safety on the job site.

3.2 Anchorage Requirements
The anchorage must be capable of
supporting 5,000 lb (22.2kN) per worker;
or it must be designed, installed, and used
under the supervision of a qualified person
as part of a complete fall arrest system
which maintains a safety factor of two.
ANSI anchorage requirements are as
follows:
For fall arrest systems, anchorages must
withstand a static load of 5,000 lb (22.2kN)
for non-certified anchorages or two times
the maximum arresting force for certified
anchorages.
For rescue systems only, anchorages must
withstand a static load of 3,000 lb (13.3kN)
for non-certified anchorages or five-times
the applied load for certified anchorages.
(NOTE: When an anchorage may be used
for both fall arrest AND rescue, the fall
arrest load requirement applies).
When more than one system is attached
to an anchorage, the above anchorage
strengths must be multiplied by the number
of systems attached to the anchorage.
Anchorage connector must be compatible
with snap hook or carabiner and must not
be capable of causing a load to be applied
to the gate (keeper).
Limits of Use
Self-Retracting Lifelines are designed for
fall arrest applications only. Never use an
SRL as a restraint or positioning device.
IMPORTANT!
A fall restraint scenario could occur
anytime:
• The user fully extends the lifeline
and applies weight or stress to that
lifeline;
• The
user
unintentionally
lifeline, without the lifeline fully
extended, and applies weight or
stress to that lifeline.
The correct application for using an
SRL allows the user to be connected
and move freely to perform the
required work tasks without locking
the lifeline or applying tension on the
lifeline at full extension.
