Instructions for Assembly and Use – Standard Configuration
Safety instructions
Cross-system
General
The contractor must ensure that the
Instructions for Assembly and Use sup-
plied by PERI are available at all times and
are understood by the site personnel.
These Instructions for Assembly and
Use can be used as the basis for creat-
ing a risk assessment. The risk assess-
ment is compiled by the contractor.
These Instructions for Assembly and
Use do not replace the risk assessment!
Always take into consideration and com-
ply with the safety instructions and per-
missible loads.
For the application and inspection of
PERI products, the current safety regu-
lations and guidelines must be observed
in the respective countries where they
are being used.
Materials and working areas are to be
inspected on a regular basis especially
before each use and assembly for:
signs of damage,
stability and
function.
Damaged components must be ex-
changed immediately on site and may
no longer be used.
Safety components are to be removed
only when they are no longer required.
Components provided by the contractor
must conform with the characteristics
required in these Instructions for
Assembly and Use as well as all valid
construction guidelines and standards.
Unless otherwise indicated, this applies
in particular to:
Timber components: Strength Class
C24 for Solid Wood according to EN
338.
Scaffold tubes: galvanised steel tubes
with minimum dimensions of Ø 48.3
x 3.2 mm according to EN 12811-
1:2003 4.2.1.2.
Scaffold tube couplings according to
EN 74.
Deviations from the standard configura-
tion are only permitted after a further
risk assessment has been carried out by
the contractor.
On the basis of this risk assessment,
appropriate measures for working and
operational safety as well as stability are
to be determined.
Corresponding proof of stability can be
provided by PERI on request if the risk
assessment and resulting measures to
be implemented are available.
Before and after exceptional occurrenc-
es that may have an adverse effect
regarding the safety of the formwork
system, the contractor must immediately
create an additional risk assessment,
with appropriate measures for ensur-
ing the stability of the scaffolding sys-
tem being carried out based on the
results,
and arrange for an extraordinary in-
spection by a competent person. The
aim of this inspection is to identify
and rectify any damage in good time
in order to guarantee the safe use of
the scaffolding system.
Exceptional occurrences can include:
accidents,
longer periods of non-use,
natural events, e.g. heavy rainfall,
icing, heavy snowfall, storms or
earthquakes.
Assembly, modification and disman-
tling work
Assembly, modification or dismantling
of scaffolds may only be carried out by
qualified specialists under the supervi-
sion of a competent person. The quali-
fied specialists must have received ap-
propriate training for the work to be car-
ried out with regard to specific risks and
dangers.
On the basis of the risk assessment and
Instructions for Assembly and Use, the
contractor must create installation in-
structions in order to ensure safe as-
sembly, modification and dismantling of
the scaffolding system.
Before initial use, the safe functioning of
the scaffold must be checked by a
competent person. The result of the
inspection must be documented in an
inspection record.
The contractor must ensure that the
personal protective equipment required
for the assembly, modification or dis-
mantling of the system, e.g.
safety helmet,
safety shoes,
safety gloves,
safety glasses,
is available and used as intended.
If personal protective equipment against
falling (PPE) is required or specified in
local regulations, the contractor must
determine appropriate attachment
points on the basis of the risk assess-
ment.
The personal protective equipment
against falling to be used is determined
by the contractor.
The contractor must
provide safe working areas for site
personnel which are to be reached
through the provision of safe access
ways. Areas of risk must be cordoned
off and clearly marked.
ensure the stability during all stages
of construction, in particular during
assembly, modification and disman-
tling of the formwork.
ensure and prove that all loads are
safely transferred.
Utilization
Every contractor who uses or allows the
scaffolding system or sections of the
scaffolding system to be used, has the
responsibility for ensuring that the
equipment is in good condition.
If the scaffolding system is used suc-
cessively or at the same time by several
contractors, the health and safety coor-
dinator must point out any possible mu-
tual hazards, and all work must be then
coordinated.
