3.2 Component Warnings and Limitations
ANCHORAGES/ANCHORAGE CONNECTORS
• Anchorages must be capable of supporting 5,000 pounds (22.2kN) per worker or meet OSHA
1926.502 requirements for a safety factor of two.
• Anchorage requirements based on ANSI are as follows:
• For fall arrest systems, anchorages must withstand a static load of 5,000 lbs. (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 lbs. (13.3kN)
for non-certified anchorages or five-times the applied load for certified anchorages. (Note:
When an anchorage may be utilized 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.
• Always work directly under the anchor point to avoid a swing-fall injury.
• When selecting an anchorage point, always refer to the fall clearance calculation information
provided with the connecting device to ensure that the anchorage point is at a height that will
not allow a user to strike a lower level should a fall occur. Remember that shock absorbers
will elongate when subjected to fall arrest forces (refer to the labels/instructions provided with
the shock absorber for additional details).
• 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).
BODY WEAR
• 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 assure proper
and secure connections before each use. All straps must be connected and adjusted to
provide a snug fit.
• Fall protection connecting devices should be attached to the back D-ring of the full-body
harness. A front D-ring attachment element may be used for fall arrest only in rescue, work
positioning, rope access, and other ANSI Z359.1 recognized applications where the personal fall
arrest system limits the maximum free fall distance to 2 ft. (0.6m) and limits the maximum arrest
force to 900 lbs. (4.0kN).
• Side and front D-rings should be used for positioning only. (Note front D-ring exception
above.); shoulder D-rings 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 only.

CONNECTING DEVICES

• Make only compatible connections.
• Use only connecting devices containing locking snap hooks or auto-locking carabiners.
• Connect in a manner that limits free fall to the shortest possible distance. [6ft. (1.8m)
maximum]
• Always visually check that each snap hook and carabiner freely engages the harness D-ring or
anchor point/anchorage connector, and that its gate (keeper) is completely closed and locked.
Never disable or restrict locking keeper or alter connecting device in any way.
• Make sure snap hook/carabiner is positioned so that its gate is never load bearing.
• The use of shock absorbers is required to reduce fall arrest forces. All Miller shock
absorbers, shock-absorbing lanyards, and self-retracting lifelines limit maximum fall arrest
forces to 1800 lbs. (8kN) or less.
• Never allow a lanyard/lifeline to pass under or entwine around the user's arms, legs, neck or
any other obstacle.
• Do not tie knots in lanyards or lifelines, or wrap around sharp, rough edges, or small diameter
structural members.
• Do not attach multiple lanyards together, or attach a lanyard back onto itself unless it is
specifically designed for that purpose.
