– the metal rope must not show any traces of
bending, scraping, corrosion or broken strands.
• Check that the lanyard locks when you pull sharply
on its end
(figure 3.b)
and that it winds and unwinds
normally along its entire length.
• Check the condition of the casing (no signs of
deformation, screws in place…).
• Check the condition and operation of the connectors:
no signs of deformation, connectors open, close and
lock correctly.
•
Check the state of the harness and connector
attachments
(figures 3.c – 3.d)
. Refer to the specific
manuals for each of the products.
• Check the complete fall-arrester system.

Functions and description
Every time before use, check
(figure 1)
:
•
The blocfor™ self-retracting fall-arrester is a
retractable fall-arrester complying with standard
EN 360. This equipment must only be used by a
single operator equipped with a fall-arresting harness
(EN 361).
• The blocfor™ self-retracting fall-arrester must only
be used for protection of operators against falls when
working at heights.
•
The blocfor™ self-retracting fall-arrester must be
secured to an anchor point, with a resistance (R) of
10 kN or more, using its connector. The retractable
lanyard must be connected by its connector to
the dorsal anchor point of the fall-arrest harness
(figure 1.b)
.
• The operator must not exceed a 20° working angle
from the vertical of the anchor point
(figure 1.c)
.
•
The blocfor™ self-retracting fall-arrester must be
protected against the infiltration of any material inside
the housing (paint, sand, mud, etc.).
• Limitations of use
(figure 1)
.
• The working load of the blocfor™ self-retracting fall-
arrester is 150 kg. By reference to their respective
manuals, you must make sure before use that all the
components of the fall-arrest system are compatible
with this load. If this is not the case, the maximum load
will be that of the fall-arrest system component with
the lowest maximum load.
• Operating temperature: -35°C to 60°C for blocfor™
self-retracting fall-arresters.
•
The blocfor™ can be connected to a temporary
tracpode™ tripod type anchor point
(figure 1.e)
.
blocfor™ SR ESD self-retracting fall-arrester
(with synthetic rope):
blocfor™ SR ESD self-retracting fall-arresters
must not be used in an environment where there
is the risk of sparks flying or the risk of a flame
coming into contact with the self-retracting fall-
arrester’s synthetic rope. The melting point of the
synthetic rope is 140°.
blocfor™ R ESD self-retracting fall-arrester:
As well as the self-retracting fall-arrest function, the
blocfor™ R ESD self-retracting fall-arrester has a
recovery function which allows a lifting rescue to
be made. Please refer to the attached instructions
specifically for the recovery version: blocfor™ 20R and
30R ESD – EN 360 - EN 1496 class B Self-retracting
fall-arrester with lifting rescue device.
The self-retracting fall-arrest function of the blocfor™ R
ESD device is the same as that on the blocfor™ ESD
self-retracting fall-arrester.
Special case: blocfor™ 1.8A ESD and 1.8B ESD
• The blocfor™ 1.8A ESD self-retracting fall-arrester
(figure 5.a)
must be secured to an anchor point, with a
resistance (R) of 10 kN or more, using the connector
located at the top of the device. The M47 connector
secured at the end of the energy absorber of the
retractable lanyard must always be connected to the
fall-arrester harness anchor point.
Any other combination in use is dangerous and
prohibited.
• The blocfor™ 1.8B ESD self-retracting fall-arrester
(
figure 5.b
) must be connected using its M47 connector
attached at the end of the energy absorber to the fall-
arrester harness anchor point. The connector at the
end of the retractable lanyard must be connected to
an anchor point with a resistance (R) anchor of 10 kN
or more.
Any other combination in use is dangerous and
prohibited.
Horizontal use:
blocfor™ self-retracting fall-arresters, with the exception
of blocfor™ 2 ESD, have been tested in horizontal use
in accordance with European spec. CNB/P/11.060
October 2014, according to the type A on edge radius
min. 0.5 mm:
see technical specification table above
.
Horizontal use is prohibited for blocfor™ 2 ESD.
Only blocfor™ 5 ESD, blocfor™ 6 ESD, blocfor™
10 ESD, blocfor™ 20 ESD, blocfor™ 30 ESD,
blocfor™ 1.8A ESD and blocfor™ 1.8B ESD are
certified for horizontal use.
If the arrest is considered to be cutting, or if there
is a sharp edge present, take all possible
precautions to avoid a fall and use edge protection
where this isn’t possible.
Before using the blocfor™ self-retracting fall-arrester,
check
(figures 1.d and 1.f)
:
– Check that the blocfor™ self-retracting fall-arrester
anchor point is located at the same height or above
the edge.
