Introduction
Elementary safety warnings
User target groups
▪This manual is aimed at all persons who will be work-
ing with the Doka product or system that it describes.
It contains information on the standard design for
setting up this system, and on correct, compliant uti-
lisation of the system.
▪All persons working with the product described
herein must be familiar with the contents of this man-
ual and with all the safety instructions it contains.
▪Persons who are incapable of reading and under-
standing this booklet, or who can do so only with dif-
ficulty, must be instructed and trained by the cus-
tomer.
▪The customer is to ensure that the information mate-
rials provided by Doka (e.g. User Information book-
lets, Instructions for Assembly and Use, Operating
Instruction manuals, plans etc.) are available to all
users, and that they have been made aware of them
and have easy access to them at the usage location.
▪In the relevant technical documentation and form-
work utilisation plans, Doka shows the workplace
safety precautions that are necessary in order to use
the Doka products safely in the usage situations
shown.
In all cases, users are obliged to ensure compliance
with national laws, Standards and rules throughout
the entire project and to take appropriate additional
or alternative workplace safety precautions where
necessary.
Hazard assessment
▪The customer is responsible for drawing up, docu-
menting, implementing and continually updating a
hazard assessment at every job-site.
This document serves as the basis for the site-spe-
cific hazard assessment, and for the instructions
given to users on how to prepare and utilise the sys-
tem. It does not substitute for these, however.
Remarks on this document
▪This manual can also be used as a generic method
statement or incorporated with a site-specific
method statement.
▪Many of the illustrations in this booklet show the
situation during formwork assembly and are
therefore not always complete from the safety
point of view.
Any safety accessories not shown in these illustra-
tions must still be used by the customer, in accord-
ance with the applicable rules and regulations.
▪Further safety instructions, especially warnings,
will be found in the individual sections of this
document!
Planning
▪Provide safe workplaces for those using the form-
work (e.g. for when it is being erected/dismantled,
modified or repositioned etc). It must be possible to
get to and from these workplaces via safe access
routes!
▪If you are considering any deviation from the
details and instructions given in this booklet, or
any application which goes beyond those
described in the booklet, then revised static cal-
culations must be produced for checking, as well
as supplementary assembly instructions.
Regulations; industrial safety
▪All laws, Standards, industrial safety regulations and
other safety rules applying to the utilisation of our
products in the country and/or region in which you
are operating must be observed at all times.
▪If a person or object falls against, or into, the side-
guard component and/or any of its accessories, the
component affected may only continue in use after it
has been inspected and passed by an expert.

Rules applying during all phases of
the assignment
▪The customer must ensure that this product is
erected and dismantled, reset and generally used for
its intended purpose in accordance with the applica-
ble laws, Standards and rules, under the direction
and supervision of suitably skilled persons. These
persons' mental and physical capacity must not in
any way be impaired by alcohol, medicines or drugs.
▪Doka products are technical working appliances
which are intended for industrial/commercial use
only, always in accordance with the respective Doka
User Information booklets or other technical docu-
mentation authored by Doka.
▪The stability of all components and units must be
ensured during all phases of the construction work!
▪The functional/technical instructions, safety warn-
ings and loading data must all be strictly observed
and complied with. Failure to do so can cause acci-
dents and severe (even life-threatening) damage to
health, as well as very great material damage.
▪Fire-sources are not permitted anywhere near the
formwork. Heating appliances are only allowed if
properly and expertly used, and set up a safe dis-
tance away from the formwork.
▪The work must take account of the weather condi-
tions (e.g. risk of slippage). In extreme weather,
steps must be taken in good time to safeguard the
equipment, and the immediate vicinity of the equip-
ment, and to protect employees.
▪All connections must be checked regularly to ensure
that they still fit properly and are functioning cor-
rectly.
It is very important to check all screw-type connec-
tions and wedge-clamped joins whenever the con-
struction operations require (particularly after excep-
tional events such as storms), and to tighten them if
necessary.
▪It is strictly forbidden to weld Doka products – in par-
ticular anchoring/tying components, suspension
components, connector components and castings
etc. – or otherwise subject them to heating.
Welding causes serious change in the microstruc-
ture of the materials from which these components
are made. This leads to a dramatic drop in the failure
load, representing a very great risk to safety.
The only articles which are allowed to be welded are
those for which the Doka literature expressly points
out that welding is permitted.
Assembly
▪The equipment/system must be inspected by the
customer before use, to ensure that it is in suitable
condition. Steps must be taken to rule out the use of
any components that are damaged, deformed, or
weakened due to wear, corrosion or rot.
▪Combining our formwork systems with those of other
manufacturers could be dangerous, risking damage
to both health and property. If you intend to combine
different systems, please contact Doka for advice
first.
▪The equipment/system must be assembled and
erected in accordance with the applicable laws,
Standards and rules by suitably skilled personnel of
the customer's, having regard to any and all required
safety inspections.
▪It is not permitted to modify Doka products; any such
modifications constitute a safety risk.
Closing the formwork
▪Doka products and systems must be set up so that
all loads acting upon them are safely transferred!
Pouring
▪Do not exceed the permitted fresh-concrete pres-
sures. Over-high pouring rates overload the form-
work, cause greater deflection and risk breakage.
Stripping out the formwork
▪Do not strip out the formwork until the concrete has
reached sufficient strength and the person in charge
has given the order for the formwork to be stripped
out!
▪When stripping out the formwork, never use the
crane to break concrete cohesion. Use suitable tools
such as timber wedges, special pry-bars or system
features such as Framax stripping corners.
▪When stripping out the formwork, do not endanger
the stability of any part of the structure, or of any
scaffolding, platforms or formwork that is still in
place!
