The Ledger is a proper connection point for the Scaf-
fold Hook attached to a Lanyard. It is recommended
thatnomorethanonesca󰀨older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 positive 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sca󰀨oldiserected.Diago-
nal braces may not be used as harness connection
points.
▪ Free fall distance should be limited to 2.0m (6’-6”) or
less in accordance with current Safety Guidelines for
thespecicconditionsofthefallhazard.Inaddition,
thesca󰀨old-specicfallprotectionplanshouldensure
that all fall zones are clear and unobstructed and that
ane󰀨ectivesca󰀨olderrescueplanhasbeendevel-
oped 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.
▪ Sca󰀨olders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.
▪ Sca󰀨oldersshouldhookonimmediatelyafterstep-
pingo󰀨aladderorothermeansofaccess.Doka
recommends the use of a properly installed Davit
Arm and retractable lanyard to ensure that workers
aretied-o󰀨whileclimbingexterior.
▪ When it is necessary to reach below the single
guardrail(e.g.xingbracingorhandlingothermate-
rials).
- Clip to:
- Available and adequate steelwork.
-Standards,butreferto“SafetyHarnessAttach-
ment Guidelines”.
- 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.
▪ Refer to “Safety Harness Connection Guide” for suit-
able/appropriate harness locations.
▪ Anchor points should always be as high as possible.
However,thisisnotalwayspracticalinsca󰀨olding
whichisusuallybuiltfromthegroundup.Ourrec-
ommendation is that where no higher anchor point is
available you should clip to the Ledger immediately
belowyourfeet.Thereissu󰀩cientspacebetween
the Ledger and the platform to clip on with a safety
harness carabiner.
