Swinging risk:
Figure 4: swinging risk
When the fall arrester enters into action, to avoid
injury due to impact, for instance against the building,
whenever possible choose an anchorage point loca-
ted vertically above the user (see figure 4)
Break-tested against an edge:
Resistance of the energy absorbing lanyard has also
been tested using a 100 kg mass on a metallic edge
with a radius of 0.5 mm. Four different tests were
conducted:
- fall from a height of 1.5 m (perpendicular to the
edge) with the shock impact measured at <6kN
- fall from a height of 1.5 m with lateral offset of 1.5
m in relation to the axis (pendulum effect) with the
shock impact measured at <6kN
- fall from a height of 2 m from the axis (perpendicular
to the edge) to test the resistance
- fall from a height of 2 m with lateral offset of 1.5 m
in relation to the axis (pendulum effect) to test the
resistance
The clearance under the edge must be at least 6.75 m.
If the Automatic Retractable Fall Arrester equipped
with an anchoring device in class C according to
standard EN 795 is used, it is also necessary to allow
for the reflection of the horizontal work positioning
support to calculate the clearance needed beneath
the user.
Remember that even if the personal fall protection
system is used in a conforming manner, falling over an
edge is liable to cause an injury (for instance, by im-
pact against part of the structure, against scaffolding
tubes or against any other sharp edges).
Rescue :
After an accident, rescue must take place within
20 minutes (trauma from suspension). The rescue
equipment and devices (for instance, descending
cables) must be operational and procedures suitable
for rescuing the users must be defined.
Users must have been given proper training about
use. The operating capacity of the rescue equipment
shall be the subject of regular checks. Rescue pro-
cedures require regular practice.
