3.0 OPERATION & USE
3.1 PLANNING:
Plan your fall protection system before starting your work. Account for all factors that may affect
your safety before, during, and after a fall. Consider all limitations and requirements de
fi
ned in Section 2.
3.2 GENERAL USE CONSIDERATIONS:
Avoid working where lifeline may cross or tangle with that of another
worker. Do not allow the lanyard to pass under arms or between legs. Do not clamp, tie, or other wise
prevent the rope grab lanyard connection handle from moving freely into the “locked” position.
3.3 SLOPED
ROOFS:
Provisions must be made (warning lines, monitors, guardrails) to prevent swing falls
from unprotected roof edges or corners. The rope grab should be connected to the body support using a
locking carabiner (direct connection) or a short lanyard. If a lanyard is used for connecting to the rope grab,
keep the length as short as possible, and never greater than three feet. The lifeline must be protected from
contact with sharp or abrasive edges and surfaces. The rope grab locking operation must not be hindered by
interference with the roof or objects on the roof surface.
3.4 UNSTABLE
SURFACES:
The rope grab is not suitable for use on unstable or slowly shifting materials, such
as sand or grain.
3.5 CONNECTING THE DETACHABLE WIRE ROPE GRAB TO THE LIFELINE:
WARNING:
In situations where a fall hazard exists, use a back-up fall arrest system, such as a lanyard,
to protect against a fall.
Step 1. Figure 7:
Hold the wire rope grab in the up position, as indicated by an arrow stamped on the wire
rope grab body.
Step 2. Figure 8:
Open the wire rope grab by pressing the button on both detent pins and pulling the
detent pins out of the wire rope grab.
Step 3. Figure 9:
Place the wire rope grab body around the lifeline, ensuring the stamped arrow is pointing
up. Install the upper detent pin.
Step 4. Figure 10:
Install the wedge/handle assembly into the wire rope grab by positioning the slot in the
wedge around the upper detent pin and against the lifeline.
Step 5. Figure 11:
Rotate the bottom end of the wedge/handle assembly into the wire rope grab until the
hole in the handle aligns with the lower hole in the wire rope grab body.
Step 6. Figure 12:
Install the lower detent pin. Insure the detent pins are securely locked. Check the
locking action by lifting the handle up and releasing. The wire rope grab must lock onto the lifeline.
If the wire rope grab does not securely lock on the lifeline, repeat steps 1 through 5. Do not use if
the wire rope grab will not operate correctly.
