A comprehensive fall protection program must be viewed as a “total system” beginning with
hazardidenticationandendingwithongoingmanagementreview.MillerFallProtectionviews
its products as a “system within a system.” Three key components of the “Miller System” need to
be in place and properly used to provide maximum worker protection.
ANCHOR POINT/ANCHORAGE CONNECTOR Therstcomponentistheanchorpoint/anchorage
connector. The anchor point, also referred to as the tie-off
point, is a secure point of attachment for connecting devices
and must be capable of supporting 5,000 lbs. (22.2kN) per
worker or meet OSHA 1926.502 requirements for a safety
factor of two, such as an I-beam or other support structure.
Anchorage connectors, such as the cross-arm strap and
eyebolt, are sometimes necessary to make compatible
connections between the connecting device and the anchor
point.
BODY WEAR The second system component is the personal protective
gear worn by workers while performing the job. Miller Fall
Protection manufactures full-body harnesses, positioning belts
andbodybeltsforuseinspecicworkenvironments.Full-
body harnesses are engineered to aid in the arrest of a free
fall and should be worn in all situations where workers are
exposed to a potential free fall. The full-body harness must be
used in conjunction with shock-absorbing equipment to keep
fall forces to a minimum. It is imperative that the harness be
worn properly.
CONNECTING DEVICE The third component of the system is the connecting device. 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 lifeline, they are designed to dramatically reduce
fall arresting forces. Rope, web or cable lanyards 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. Used properly
with each other, they form the “Miller System” and become a critically important part of
the “total fall protection system.”
3.0 System Compatibility
The Miller MightEvac Self-Retracting Lifeline is designed for use with Miller approved
components. Substitution or replacement with non-approved component combinations or
subsystems or both may affect or interfere with the safe function of each other and endanger
the compatibility within the system. This incompatibility may affect the reliability and safety of the
total system.

3.2 Component Warnings and Limitations
ANCHORAGES
• 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-certied anchorages or two times the maximum arresting force for certied anchorages.
• For rescue systems only, anchorages must withstand a static load of 3,000 lbs. (13.3kN)
for non-certied anchorages or ve-times the applied load for certied 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.
• Ensure that the anchorage connector is at a height that will not allow a lower level to be struck
should a fall occur. When selecting an anchorage point, always remember that shock absorbers
will elongate when subjected to fall arrest forces. Refer to the labels and instructions provided with
the connecting device to obtain the maximum elongation distance. This maximum elongation
distance must be considered when choosing an anchor point.
• Anchorage connector must be compatible with snap hook or carabiner and must not be
capable of causing a load to be applied to the keeper.
• Never use an anchorage connector which will not allow snap hook or carabiner keeper to
close.
BODY WEAR
• Visually check all buckles to assure proper and secure connections before each use. All
straps must be connected and adjusted to provide a snug t.
• Fall protection connecting devices should be attached to the back D-ring of a 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 non-locking snap hooks to a harness D-ring.
• 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.
• Always visually check that each snap hook and carabiner freely engages the D-ring or anchor
point, and that its 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 keeper is never load bearing.
• The use of shock absorbers is required to reduce fall arresting forces.
• Tie-off in a manner which ensures a lower level will not be struck should a fall occur.
• Connect in a manner that limits free fall to the shortest possible distance. [6ft. (1.8m)
maximum]
• Never allow a retractable lanyard or lifeline to become slack.
• Never allow a lanyard 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
specically designed for that purpose.

4.0 Operation
Retrieval Operation
―FOR EMERGENCY USE ONLY―
The MightEvac retrieval mechanism is to be used only in the event of an
emergency. Do not use for routine hoisting of personnel or materials.
NOTE: It is recommended to pull out
several feet of lifeline and hold in position
before engaging retrieval mechanism.
Always maintain tension on the lifeline
while in retrieval mode.
Pull out on the plunger pin until the ratchet
handle pops outward. It may be necessary to
rotate the handle slightly to fully engage the in-
ternal gears. The plunger pin should snap back
into its original position when the gears are fully
engaged. The unit is now in retrieval mode.
NOTE: A rescue may be executed either
by raising or lowering a person to safety.
TO RAISE: While maintaining light tension on
the lifeline, rotate the ratchet handle counter-
clockwise (CCW) to crank the lifeline into the
housing.
TO LOWER: To extend lifeline from the housing
(to lower), rotate ratchet handle in clockwise
(CW) direction. [NOTE: If the internal brak-
ing mechanism has been activated, such as
withafallarrest,itisnecessarytorstcrank
in the upward direction (CCW) for one-half to
one rotation, then reverse the direction (CW) to
begin lowering. A minimum of 75 lbs. (34kg) is
required for lowering.]
WARNING: Always ensure that the
plunger pin has returned completely into
the locked position when changing the
unit from retractable to retrieval mode.
Do not use the unit if it will not hold the
load while in retrieval mode.
