ANCHORAGE: Select a rigid anchorage point that is capable of supporting the required loads. The an-
chorage location must be carefully selected to reduce possible free fall and swing fall hazards and to
avoid striking an object during a fall. The anchorage should be generally level (horizontal) to prevent
the anchorage connector from sliding down an incline when in use, which could cause serious injury
to the user.
FREE FALL: Maximum free-fall distance six feet or maximum fall arrest force of 1800 lbs.
Avoid lower level contact.

to arrest the fall before striking the ground or other object. Energy absorbers can extend the fall
arrest distance by up to 42 inches (106.7 cm). The illustration to the right shows how to estimate
fall clearance distance when using an energy absorbing lanyard or energy absorber subsystem.
Other factors may influence the required clearance distances. For example, using an energy ab-
sorbing lanyard or energy absorber with a rope grab (fall arrestor) may require additional clear-
ance due to stretch in the lifeline or sliding of the rope grab on the lifeline during fall arrest. Some
full body harness models incorporate a sliding (positional) D-ring in the back as the fall arrest
attachment, movement of this D-ring during fall arrest can increase the fall clearance distance
required. Use caution when assembling system components that could act to extend the fall ar-
rest distance (and therefore fall clearance required). Refer to manufacturer's instructions for
each part of the system for more information on fall clearance.

When using lanyards commonly referred to
as "100% tie-off", "Y" type, "double" or "twin
leg" shock absorbing lanyards. This supple-
ment provides additional information on the
use of these types of lanyards that are used
with a personal fall arrest systems.
Practices that must be followed in order to
use a 100% tie-off lanyard safely.
1.
The shock absorber pack portion of the
lanyard assembly MUST be connected
to the back dorsal D-ring ONLY, by way
of a double locking lanyard snap hook
(other connectors provided, consult
ULTRA-SAFE, INC.) connect shock ab-
sorber directly to the dorsal D-ring.
2.
Do not connect shock absorber to the
anchorage point at any time.

3.
Do not connect the unused leg of the
lanyard assembly to any portion of the
full body harness, unless a specifically
designed lanyard snap hook loop re-
tainer is provided for this purpose.
4.
When connecting from one anchorage
point to the next (traversing a vertical or
horizontal structure) do not connect to
an anchorage point further apart than,
the length of the lanyard.
5.
When using a 100% tie-off lanyard as-
sembly, do not allow any part of the lan-
yard to pass under arms or legs.
6.
Connection of both lanyard legs to sep-
arate anchorage points is acceptable,
as long as anchorage points are within
the length of the lanyard.
