Elementary safety warnings
User Information Floor props Eco 15
User target groups
▪ This booklet 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 utilisation of the system.
▪ All persons working with the product described
herein must be familiar with the contents of this
booklet 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 difficulty, must be instructed and trained by the customer.
▪ The customer is to ensure that the information mate-
rials provided by Doka (e.g. User Information booklets, Instructions for Assembly and Use, Operating
Instruction manuals, plans etc.) are up to date and
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 regulations
throughout the entire project and to take appropriate
additional or alternative workplace safety precautions where necessary.
Remarks on this booklet
▪ This booklet 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 illustrations must still be used by the customer, in accordance with the applicable rules and regulations.
▪ Further safety instructions, especially warnings,
will be found in the individual sections of this
booklet!
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 calculations must be produced for checking, as well
as supplementary assembly instructions.
Hazard assessment
▪ The customer is responsible for drawing up, docu-
menting, implementing and continually updating a
hazard assessment at every job-site.
This booklet serves as the basis for the site-specific
hazard assessment, and for the instructions given to
users on how to prepare and utilise the system. It
does not substitute for these, however.
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
▪ Der Kunde muss sicherstellen, dass der Auf- und
Abbau, das Umsetzen sowie die bestimmungsgemäße Verwendung des Produktes gemäß den
jeweils geltenden Gesetzen, Normen und Vorschriften von fachlich geeigneten Personen geleitet und
beaufsichtigt wird.
Die Handlungsfähigkeit dieser Personen darf nicht
durch Alkohol, Medikamente oder Drogen beeinträchtigt sein.
▪ Doka-Produkte sind technische Arbeitsmittel, die nur
für gewerbliche Nutzung gemäß den jeweiligen
Doka-Anwenderinformationen oder sonstigen von
Doka verfassten technischen Dokumentationen zu
gebrauchen sind.
▪ Die Standsicherheit und Tragfähigkeit sämtlicher
Bauteile und Einheiten ist in jeder Bauphase sicherzustellen!
▪ Auskragungen, Ausgleiche, etc. dürfen erst betreten
werden, wenn entsprechende Maßnahmen zur
Standsicherheit getroffen wurden (z.B.: durch
Abspannungen).
▪ Die funktionstechnischen Anleitungen, Sicherheit-
shinweise und Lastangaben sind genau zu beachten
und einzuhalten. Die Nichteinhaltung kann Unfälle
und schwere Gesundheitsschäden (Lebensgefahr)
sowie erhebliche Sachschäden verursachen.
▪ Feuerquellen sind im Bereich der Schalung nicht
zulässig. Heizgeräte sind nur bei sachkundiger
Anwendung im entsprechenden Abstand zur Schalung erlaubt.
▪ Die Arbeiten sind an die Wetterbedingungen anzu-
passen (z.B. Rutschgefahr). Bei extremen Wetterbedingungen sind vorausschauende Maßnahmen
zur Sicherung des Gerätes bzw. umliegender Bereiche sowie zum Schutz der Arbeitnehmer zu treffen.
▪ Alle Verbindungen sind regelmäßig auf Sitz und
Funktion zu überprüfen.
Insbesondere sind Schraub- und Keilverbindungen,
abhängig von den Bauabläufen und besonders nach
außergewöhnlichen Ereignissen (z.B. nach Sturm),
zu prüfen und gegebenenfalls nachzuziehen.
▪ Das Schweißen und Erhitzen von Doka-Produkten,
insbesondere von Anker-, Aufhänge-, Verbindungsund Gussteilen etc., ist strengstens verboten.
Schweißen bewirkt bei den Werkstoffen dieser Bauteile eine gravierende Gefügeveränderung. Diese
führt zu einem dramatischen Bruchlastabfall, der ein
hohes Sicherheitsrisiko darstellt.
Das Ablängen von Ankerstäben mit Metalltrennscheiben ist zulässig (Wärmeeinbringung nur am
Stabende), jedoch ist darauf zu achten, dass der
Funkenflug keine anderen Ankerstäbe erhitzt und
damit beschädigt.
Es dürfen nur jene Artikel geschweißt werden, auf
die in den Doka-Unterlagen ausdrücklich hingewiesen wird.
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 formwork, 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!

Transporting, stacking and storing
▪ Observe all regulations applying to the handling of
formwork and scaffolding. In addition, the Doka
slinging means must be used - this is a mandatory
requirement.
▪ Remove any loose parts or fix them in place so that
they cannot be dislodged or fall free!
▪ All components must be stored safely, following all
the special Doka instructions given in the relevant
sections of this booklet!
Maintenance
▪ Only original Doka components may be used as
spare parts. Repairs may only be carried out by the
manufacturer or authorised facilities.

The main features:
▪ High load-bearing capacity
- see the section headed 'Permitted carrying
capacity'
▪ Quick connection:
Head adapters of various types can be attached in a
crane-handling-safe manner with the spring-locked
connecting pin
▪ Drop-out latch:
For safety reasons, Doka props have latches to prevent the inner tube sliding out of the outer tube.
▪ the special geometry of the thread, which makes the
prop easier to release even when it is under high
load

a clear 10 cm gap so that the operator's hands are
not trapped.
▪ galvanised, long-life constructional design

secure intermediate props for floor formwork (see
user information document for Dokaflex 15).
➤ When using props as temporary reshoring, press
them sufficiently tightly to the underside of the floor
slab so that they cannot topple.
