Honeywell MILLER MIGHTYLITE+ MML-OGC1 User Manual page 8

Anchor device vertically overhead whenever
possible. For the purposes of this instruc-
tion manual, an overhead application
implies that there is no slack in the lifeline
when the unit is mounted above the user
and connected to the user's back D-ring.
For suitability in other installation applica-
tions, refer to section 4.0 Installation/Use.
Never work above the device, unless
instructions allow for such installation
applications for your specific self-retracting
lifeline model.
Select Self-Retracting
limiters may be used with Honeywell-
approved horizontal
Always refer to the instructions provided
with the horizontal lifeline system to
determine if your Self-Retracting Lifelines
model can be used with the system.
The device should be installed and used
in such a manner as to minimize the
potential for a swing fall.
Do not tie knots in lifelines, or wrap around
sharp, rough edges, or small diameter
structural members. Do not attach multiple
connecting devices together, or attach a
lanyard/lifeline back onto itself unless it is
specifically designed for that purpose.
3.3 Connecting Devices
Use only connecting devices containing
locking snap hooks or locking carabiners.
Connect in a manner that limits free fall to
the shortest possible distance: 6ft (1.8 m)
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
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 lifelines, and
Self-Retracting Lifelines limit maximum
fall arrest forces to 1800 lb (8kN) or less.
Never allow a lifeline to pass under or
entwine around the user's arms, legs, neck
or any other obstacle.

4.0 Installation/Use
WARNING
All Honeywell Miller Self-Retracting
Lifelines must be inspected and
tested for locking and retraction
before each use (Ref. section 7.0 In-
spection & Maintenance).
4.1 Typical Overhead Installation*
(See Fig. B & C)
Miller Self-Retracting Lifelines are typically
mounted to an overhead anchorage by the
anchorage attachment using a locking
carabiner or other Honeywell-approved
mounting device. (see 3.2 Anchorage
requirements for more details)
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).
Review all warnings and instructions when
selecting a mounting location. The device
should be installed and used in such a
manner as to minimize the potential for a
swing fall.
*Refer to 2.2 Warnings and Limitations
- Capacity
4.2 Horizontal Use
Self-Retracting Lifelines shall be used for
overhead use only, if they are classified
as Class 1 (ANSI) or Class SRD (CSA).
Self-Retracting Lifelines used for horizontal
applications shall be classified as Class 2
is
(ANSI) or Class SRD-LE (CSA). Refer to the
product label for application compliance.
When installing a Self-Retracting Lifelines
for horizontal use, special considerations
and warnings apply. The following should
be considered when mounting SRLs for
horizontal use:
• Only use Edge (ANSI Class 2) models
due to the likelihood of contact with
sharp edges in this application
• Free fall distance may exceed 6ft
