Making the Installation
3.4
Preparation of Materials at the Installation Site
Locate all rail sections and installation hardware in a dry place outside the zone of any possible trajectory
of tools or materials, which could fall from overhead during the installation. If this is not possible, install
protective netting of proper strength and mesh above where the ground worker may be while assisting the
climbing installer.
Note:
In some installations, such as confined spaces underground, the materials must be moved down-
ward. If materials are outside or where they can be contaminated, protect them with tarp and
keep them off the ground with pallets.
Before mounting, clean all parts of any residual foreign matter - especially at the connecting areas. Avoid
contact with mortar, concrete or other materials, which may adhere to surfaces. Remove any such contam-
inants immediately. The running surfaces for the fall arrester are particularly important to check for foreign
matter. Check all parts for deformations, improper surface finish, alterations and manufacturing defects
which could affect performance or fit.
Segregate all parts and orient rail sections to facilitate connection at the end which is to be uppermost (notch
opening "up") when being moved for mounting.
Always check to be sure the rail notches are up or the fall arrester will otherwise not lock.
Place installation hardware into a bolt bag and/or climber - borne pouches to ease removal for installation
aloft. Consult the installation plan and lay out special rails (e.g. curved sections) in the sequence they will
be installed. Two-way radio contact is very helpful on long runs of rail to coordinate when things such as
special sections are needed next in the installation sequence. Radio contact is also important to keep the
two installers aware of their respective needs or problems and to provide means of communicating safety
hazards or emergencies.
To assist the climbing installer, it is sometimes preferred to pre-assemble some parts on the ground. For
example, the rail connector assembly can be attached (not tightly) to the bottom of a rail section before it is
moved to the mounting point. (Care must be taken to assure the parts do not come loose and fall during
movement.) The climbing installer is thus saved some time and motion in making the first coupling of that
rail section. It is usually not advisable to pre-assemble parts of mounting assemblies on the ground as their
precise location must be decided by the climbing installer.

As an extra precaution, the ground person may install a piece of heavy wire at the top of each rail section
before moving it to the mounting place with the handline. The wire goes through the top slot in the rail, then
around one side of the rail, and is secured by twisting the wire ends together. The wire must not be removed
until the next rail section is properly connected. This helps to remind the climbing installer which end is "up".
It also prevents the Dyna-Glide fall arrester from slipping out of the top rail and falling to the ground.
Note:
During rail installation it is suggested that a fall arrester be mounted on the rail by the climbing
installer and moved upward with each rail section installation to check for misfit rail abutments
and unsatisfactory fall arrester-to-rail interfacing which may require remedy before the installation
is complete.
The climber must never connect himself to this fall arrester until the entire system installation is completed
and inspected.
