JOINING OF VERTICAL SAFERAIL -SAFETY RAILS
•
The SafeRail Joint-extension piece MM 201 is attached using the holes at the ends of the Vertical
SafeRail-safety rails.
3.6
GROUND CLEARANCE
•
We recommend allowing a ground clearance of 500 mm for the Vertical SafeRail-safety rail to
ensure that the SafeRail Carriage-safety carriage can be easily coupled with the Vertical SafeRail-
safety rail and removed from it. The maximum ground clearance allowed is 1000 mm.
3.7
INSTALLATION OF SAFERAIL CARRIAGE STOPPER -CARRIAGE BARRIERS
•
At the top end of the topmost Vertical SafeRail-safety rail, install a SafeRail Carriage Stopper-
carriage barrier MM 313 or the unlocking model MM 312. This prevents the SafeRail Carriage-safety
carriage from coming off the safety rail accidentally.
•
At the bottom end of the bottom Vertical SafeRail-safety rail, install an unlocking SafeRail Carriage
Stopper-carriage barrier MM 311.
3.8
INSTALLATION OF SAFERAIL INSTRUC TIONAL SIGNS
•
The Vertical SafeRail-safety rail must always be equipped with an instructional sign that informs the
user of the need to use a full-body harness and a SafeRail Carriage-safety carriage when using the
SafeRail fall arrest system.
•
The instructional sign must be installed in such a manner that it is easy to spot and clearly visible to
the user before using the system.
•
The installation month and year are also to be recorded on the instructional sign. The party carrying
out the installation is responsible for adding this information on to the sign.
3.9
THINGS TO BE ADHERED TO DURING INSTALLATION
•
During the installation of the Vertical SafeRail-safety rail, you must also make sure that the ladders
on to which the safety rail is installed have been fastened appropriately and securely.
•
When tensioning the SafeRail Joint-extension piece MM 201, make sure that the width of the safety
rail groove remains at 15 mm. The width must be the same on both sides of the extension piece.
•
CAUTION! Each section of the safety rail where the SafeRail Carriage-safety carriage used with the
Vertical SafeRail-safety rail can come off the rail must be equipped with a stopper. As mentioned in
section 3.7, the stoppers designed to be used at the top end of SafeRail ladders and/or Vertical
SafeRail-safety rails include the unlocking Carriage Stopper-carriage barrier MM 312 and the fixed
Carriage Stopper-carriage barrier MM 313. Carriage Stopper-carriage barrier MM 311 is designed to
be used at the bottom end of SafeRail ladders and/or Vertical SafeRail-safety rails.
