Connection to a Ledger
The Ledger is a proper connection point for the Scaffold
Hook attached to a Lanyard. It is recommended that no
more than one scaffolder be attached to any Ledger at
the same time.
Both Ledger ends must be attached with tightened
wedges to a Standard that is supported by two or more
Ledgers attached to the same rosette. To ensure a pos-
itive connection is created it is recommended that joints
between Standards are pinned together (ensure site
local regulations and current Legislation are followed).
▪
Diagonal braces must be installed as per Doka rec-
ommendations and/or engineering design and they
must be installed as the scaffold is erected. Diagonal
braces may not be used as harness connection
points.
▪
Free fall distance should be limited to 2.0
m
(6'-6")
or
less in accordance with current Safety Guidelines for
the specific conditions of the fall hazard. In addition,
the scaffold-specific fall protection plan should
ensure that all fall zones are clear and unobstructed
and that an effective scaffolder rescue plan has been
developed that can be mobilized quickly in the event
that an arrested fall incident occurs.
▪
All persons using fall protection systems must be
trained in the proper installation and safe use of fall
protection equipment, as required by Work at Height
Regulations.
▪
Contractors and their employees must comply with
the Work at Height Regulations.
▪
Scaffolders should use an appropriate safety har-
ness at all times such that the individual stays fully
protected from falling when working at heights, Scaf-
folders should use suitable safe zones as per TG4
(current revision), at all times.
▪
Scaffolders should hook on immediately after step-
ping off a ladder or other means of access. Doka rec-
ommends the use of a properly installed Davit Arm
and retractable lanyard to ensure that workers are
tied-off while climbing exterior.
▪
When it is necessary to reach below the single
guardrail (e.g. fixing bracing or handling other mate-
rials).
-
Clip to
:
- Available and adequate steelwork.
- Standards.
-
Do not clip to
:
- Ringlock Bay Braces.
- Standards not supported by two or more Ledg-
ers attached to the same rosette.
- Puncheons or cantilevered components.
- Pipework, plant guardrails, cable racks etc.
▪
Anchor points should always be as high as possible.
However, this is not always practical in scaffolding
which is usually built from the ground up. Our recom-
mendation is that where no higher anchor point is
available you should clip to the Ledger immediately
below your feet. There is sufficient space between
the Ledger and the platform to clip on with a safety
harness carabiner.
