Prohibited Use - Tractel blocfor 1.8 EVO ESD Manual De Instalación, De Utilización Y De Mantenimiento

and/or descending, the lanyard operator is maintained
tensioned by the return spring.
GB In addition the blocfor™ EVO ESD automatic retraction
fall arrester is fitted with a safety system guaranteeing
that the fall of an operator is stopped in all safety even if
the fall occurs when the strap has completely come out of
the blocfor™ EVO ESD automatic retraction fall arrester.
If this equipment is connected to an EN 795 class C
lifeline, it is imperative to add the maximum deflection
of the anchor point defined in the instructions for use of
the anchor point to the draft (values below).
6.1. Vertical use
The air clearance H (figure 1.g) is the free space under
the feet of the operator. It is defined by the formula:
which breaks down as follows:
3 m = height of fall with the blocfor™ self-retracting fall-
arrester: 2 metres + 1 meter security.
Hp = maximum deflection of the anchor point defined in
the instructions for use of the anchor point.
6.2. Horizontal use
The vertical clearance H (figure 1.h) is the free space
below the operator during horizontal use. This is
defined by the formula below:
which breaks down as follows:
5 m = fall height with the blocfor™ automatic retraction
fall arrester in horizontal use: 4 metres + 1 metre for
additional safety.
Hp = the maximum anchor point deflexion as defined in
the anchor point usage manual.
6.3. Factor 2 use
The air clearance H (figure 1.f) is the free space under
the feet of the operator. It is defined by the formula:
which breaks down as follows:
6 m = height of fall with the blocfor self-retracting fall
arrester: 5 metres + 1 meter security.

H = 3 m + Hp
H = 5 m + Hp
H = 6 m + Hp
Hp = maximum deflection of the anchor point defined in
the instructions for use of the anchor point.

7. Prohibited use

Figure 2.
It is strictly forbidden:
• to install or use the blocfor™ self-retracting fall-
arrester without first having been authorised, trained
and recognised to be qualified in the use of the device,
or otherwise, without the supervision of an authorised
operator, trained and recognised to be qualified in use
of the device.
• to use the blocfor™ self-retracting fall-arrester if any
of the markings are not legible.
• to install or use the blocfor™ self-retracting fall-
arrester without first having carried out the preliminary
checks.
• to use a blocfor™ self-retracting fall-arrester which
has not been covered by a periodical inspection over
the past 12 months by a technician having authorised
re-use in writing.
• to connect the blocfor™ self-retracting fall-arrester to
a point which has not been covered by a periodical
inspection over the past 12 months by a qualified
technician having authorised re-use in writing.
• to use the blocfor™ self-retracting fall-arrester for
any other application other than for automatic fall
protection of operators.
• to secure the blocfor™ self-retracting fall-arrester by
any other means other than its anchor point.
• to use the blocfor™ self-retracting fall-arrester in
contradiction with the information specified in the
section "15. Life cycle".
• to use the blocfor™ self-retracting fall-arrester as a fall
protection system for more than 1 operator.
• to use the blocfor™ self-retracting fall-arrester by
an operator whose weight, equipment included, is
greater than 150 kg.
• To use the blocfor™ self-retracting fall-arrester with a
load of between 100 kg and 150 kg (total weight of
the operator, equipment and tools) if any component
in the fall-arrest system has a lower maximum load.
• to use the blocfor™ self-retracting fall-arrester if it has
served to stop a fall.
• to use the blocfor™ self-retracting fall-arrester as a
means of suspension or to hold a work position.
• to use the blocfor™ self-retracting fall-arrester in a
highly corrosive or explosive atmosphere.
• to use the blocfor™ self-retracting fall-arrester outside
the temperature range specified in this manual.
• to use the blocfor™ self-retracting fall-arrester if the
fall clearance is not sufficient with respect to a falling
operator.
• to use the blocfor™ self-retracting fall-arrester if
any obstacle is located along the fall path or on the
swinging path when used in a horizontal configu ration.
