Carriage-safety carriage will not lock on to the locking notches on the Vertical SafeRail-
safety rail and thus won't stop the user from falling, subjecting them to mortal danger.
o
If a Carriage Guide-carriage guide MM 301 has not been installed at both the top and bottom
end of the SafeRail ladder and/or the Vertical SafeRail-safety rail, it is possible for the user
to accidentally couple the SafeRail Carriage-safety carriage with the safety rail the wrong
way round, in which case the carriage will not lock on to the locking notches on the Vertical
SafeRail-safety rail and thus will not stop the fall. This will subject the user to mortal danger.
o
If the Carriage Guide-carriage guide MM 301 has been installed incorrectly such that the
locking screw is placed on the right side of the safety rail instead of the left, it is possible for
the user to accidentally couple the SafeRail Carriage-safety carriage with the safety rail the
wrong way round, in which case the carriage will not lock on to the locking notches on the
Vertical SafeRail-safety rail and thus will not stop the fall. This will subject the user to mortal
danger.
o
If Carriage Stopper-carriage barriers have not been installed to both the top and bottom
ends of the SafeRail ladder and/or the Vertical SafeRail-safety rail, the SafeRail Carriage-
safety carriage may come off the safety rail accidentally, thus subjecting the user to mortal
danger. In this case, mortal danger is particularly present at the top end of the safety rail,
where the risk of falling from a height is significant.
o
If an unlocking Carriage Stopper-carriage barrier MM 312 has been installed incorrectly at
the bottom of the SafeRail ladder and/or the Vertical SafeRail-safety rail instead of the top
end, there is a risk that the SafeRail Carriage-safety carriage may come off the safety rail
accidentally, in which case the user may fall. At the bottom end of the safety rail, the fall is
unlikely to be at height, if the installation is compliant with the ground clearance specification
of the installation instructions for the SafeRail ladder and/or the Vertical SafeRail-safety rail,
which allows for a maximum ground clearance of 1000 mm.
o
If an unlocking Carriage Stopper-carriage barrier MM 311 has been installed incorrectly at
the top end of the SafeRail ladder and/or the Vertical SafeRail-safety rail instead of the
bottom, there is a risk that the SafeRail Carriage-safety carriage may come off the safety rail
accidentally, thus subjecting the user to mortal danger. In this case there is a risk of falling
from significant height.
o
If SafeRail ladders and/or Vertical SafeRail-safety rails have been connected to each other
using some other components than the SafeRail Joint-extension pieces or the SafeRail
Joint- extension pieces have not been appropriately tensioned, there is a danger that the
joints fail and the SafeRail Carriage-safety carriage comes off the safety rail. This may
subject the user to mortal danger.
1.2
INSPECTING THE SAFETY HARNESS AND THE SUPPORT ROPE BEFORE EACH
USE
•
The harness used must be a full-body harness conformant with the EN 361 standard, which is in the
condition required by the relevant regulations. The front of the harness must have a D-ring, or
another approved attachment point for attachment to the SafeRail Carriage-safety carriage.
•
The attachment point on the safety harness is attached directly to the carabiner on the SafeRail
Carriage-safety carriage, which conforms to the requirements of the EN 362 standard. Check that
the locking screw-gate on the carabiner closes securely.
•
The safety harness must be adjusted to fit the user sufficiently tightly.
