Tractel derope STD Manual De Instalación, Operación, Mantenimiento página 12

DANGER: Following each use, whether for a
single descent or repeated descents, the derope™
descender must be inspected by a technician
GB
trained and qualified for this operation.
DANGER: The combined descent height must
be monitored. If the combined descent height
exceeds the limits indicated in the table of § 10-1,
whatever the time taken to reach this combined
descent height, the descender must be overhauled
as instructed in § 10-1 by a technician trained and
qualified for this operation.
The descender can be used at temperatures between
-35°C and +50°C.
DANGER: For use at negative temperatures
(between -35°C and 0°C), the descender must be
dry, including the rope.
DANGER: The technician using the derope™
descender must weigh at least 30 kg.
DANGER: To avoid any risk of burns, it is
prohibited to touch the derope™ descender during
operation and before it has cooled down.
7.2. Voluntary vertical evacuation
This type of evacuation must be performed using
a derope™ STD, derope™ UP A, derope™ UP B or
derope™ UP K descender; the last two models are
intended for use with a ladder.
The person to be evacuated must be equipped with
a fall-arrest harness (EN 361), a rescue harness
(EN 1497) or a rescue strap (EN 1498 class A or B).
During a voluntary vertical evacuation, the person must
not move away by more than 20° with respect to the
vertical to avoid any excessive swinging effects.
1. After you have installed the derope™ descender in
compliance with the instructions in § 6, proceed as
follows:
2. Fasten the person to be evacuated or hook yourself
up by the connector at the end of the evacuation
strand of the derope™ descender to:
– a fall-arrest harness fastening point EN 361: these
points are marked A when they can be used alone
and A/2 when they must be used in combination
with another fastening point marked A/2.
– a rescue harness fastening point EN 1497 or a
rescue strap EN 1498 class A or B, identified by a
label near the fastening point.
3. Pull the free strand of the rope to tension the
evacuation strand.
4. Run the free strand of the rope through the rope
guide then through the clam cleat.

5. If necessary, check that the handwheel handle on
the derope™ UP descender is folded in.
6. Place the person to be evacuated above the open
space. The person will not descend since the rope
is blocked by the clam cleat.
7. Start the descent by releasing the free strand of the
rope in the clam cleat.
8. Once the person has reached the ground, unfasten
the person.
9. Once the connector of the free strand has come
back up to the derope™ descender after the
evacuation, if there is another person waiting to be
evacuated, repeat the procedure detailed in points
1 to 7.
10. For repeated descents, you must observe the
maximum number of descents indicated in the table
in § 7.1.
7.3. Voluntary evacuation on an inclined
surface (Fig. 12)
This type of evacuation procedure must be performed
using a derope™ STD or derope™ UP A descender.
The evacuation location must be equipped with a
tensioned cable or rope forming an angle with the
vertical of between 30° and 60°.
A double in-line pulley with a multi-anchoring plate must
be positioned at the top of the cable.
The person to be evacuated must be equipped with
a fall-arrest harness with, preferably for comfort
purposes, a sternal fastening point (EN 361), a rescue
harness (EN 1497) or a rescue strap (EN 1498 class B).
1. After you have installed the derope™ descender
as instructed in § 6, connect the evacuation strand
of the derope™ descender on the multi-anchoring
plate, mounted on the double in-line pulley.
2. Install a lanyard equipped with 2 connectors
between the anchoring plate of the double in-line
pulley and:
– a fastening point of the fall-arrest harness EN 361.
These points are marked A when they can be
used alone or A/2 when they must be used in
combination with another fastening point marked
A/2.
– a fastening point of the rescue harness EN 1497 or
of the rescue strap EN 1498 class B, identified by a
label next to the fastening point.
3. Pull on the free strand of the derope™ descender to
tension the evacuation strand.
4. Run the free strand of the rope through the rope
guide then through the clam cleat.
5. Make sure that the handwheel handle on the
derope™ UP descender is folded.
