Before Each Use - 3M DEUS 7300 Manuel D'instruction

Before Each Use

L
IMPORTANT: Check every component
of your controlled descent system, including:
1) harnesses, 2) connectors, 3) DEUS 7300
device, 4) rope, 5) anchorage connectors,
6) anchor point, and 7) Rescue Transfer Unit.
You are responsible for making sure that every
component of your system is safe and ready
for use.
Checking a DEUS rope before use
L
IMPORTANT: Ropes degrade whether they
are used or not. Therefore, a rope should be
checked before each use. It is the responsibility
of the user to decide if a rope is safe to use. If you
have doubts, do not use the rope. Check:
• The mantle (outside covering) of the rope by
performing a visual and tactile inspection.
Check for frayed fibers, cuts, abrasion, fibers
pulled from the braid, and dirt. UV degradation
from sunlight will cause rope fibers to become
brittle and disintegrate. All of these things
indicate wear and damage.
• The kern (core) of the rope by performing a
tactile inspection. Run the rope through your
fingers checking for soft spots that indicate
damage to the core fibers.
• Knots and end-terminations on the rope by
performing a visual and tactile inspection. Look
for cuts, abrasion, excessive tightening of knots,
broken stitches in sewn eyes, and dirt. All of
these things indicate wear or damage.
Checking connections before use
L
IMPORTANT: Connections like carabiners,
swagged cables and sewn slings can be used to
rig the 7300 device. Check connections before
every use. It is the user's responsibility to decide if
a connection is safe to use. If you have doubts, do
not use the connection. Check:
• Cracks, bends or gates that do not close
properly in mechanical connections, and
springs in auto-locking connectors. Make sure
auto-locking connectors do, in fact, auto-lock.

• Broken stitches, cuts, abrasion and dirt in sewn
webbing slings.
• Broken wires, damaged eyes or broken swages
in cable assemblies.
Checking a harness before use
L
IMPORTANT: Harnesses degrade whether
they are used or not. Therefore, a harness
should be checked before each use. It is the
responsibility of the user to decide if a harness
is safe to use. Please reference your harness
manufacturer's user instructions for specific
inspection criteria. If you have doubts, do not use
the harness. Check:
• Webbing for cuts, abrasion, broken stitches or
UV degradation.
• Hardware for cracks, bends or buckles that do
not open and close properly.
• Connection points that are worn or broken.
Checking an anchorage before use
L
IMPORTANT: DEUS 7300 devices should
only be rigged to an appropriate anchor point.
Life-safety rated anchor points are best. It is the
user's responsibility to select an anchor point
appropriate for use. An anchor point can be
subjected to impact loads when used and can
fail without warning. Check your anchor point
and the anchorage connector before each use.
It is the responsibility of the user to decide if an
anchor point and anchorage connector is safe to
use. If you have doubts, do not use the anchor
point or the anchorage connector.
Checking is safety
L
IMPORTANT: Do not hesitate to retire a
DEUS Rescue product showing signs of wear
which might affect its strength or function, or
that may restrict proper operation. For your
safety, the following three-level check is prudent:
1. Before each use, check the condition of the
7300 controlled descent device and every
component of the system with which it is used.
It is highly recommended that two people,
independently, check the entire system.
