General usage considerations Alsipercha System
General usage considerations
These considerations complement those described in the system’s
assembly and disassembly process.
The system has been designed and calculated for the specifi c uses
and applications described in this manual. Therefore, Alsina accepts
no responsibility for the use of the equipment in situations other than
those described in this manual.
The Alsina Group does not participate in the management or execution
of the project, and the client is solely responsible for the proper use of
the materials supplied.
All the components have suffi cient strength and stability to support
the loads and stresses described in these instructions. It is essential
to place all the system’s components with all the accessories mounted
and properly assembled.
The technical operating instructions, safety indications and data on
loading conditions must be scrupulously observed and followed.
Failure to respect these indications may lead to accidents and severe
injuries (or death) and to considerable material damage.
Systems should not be mixed as they may be incompatible and are
neither designed for nor adapted to the assembly. Alsina rejects all
liability if the system components are replaced with similar components
supplied by another company.
Before starting assembly, the person in charge must plan for loading
and unloading, material storage, and laying out and marking the
areas where the work is to take place, in accordance with the general
organization of the construction work.
The following PPE must be used in the assembly/disassembly:
Gloves, boots, goggles, helmet, refl ective vest, etc.
For heights greater than 3.5 m, a safety harness must be used.
The equipment must be assembled by specialized personnel.
Work areas must be kept clean and orderly.
The largest possible number of operations must be carried out on the
fl oor.
Formwork must be interrupted in the event of heavy rain, snow,
lightning storms, or winds over 65 km/h (service wind pressure of
0.2 kN/m²), removing any materials or tools that may be loose.
Sources of fi re are not allowed near the formwork area.
Workers must always access the work area through the areas made
available for this purpose.
Storage
Having an area designated for compiling and controlling all the
elements supplied is recommended.
Areas must be delimited for the storage of materials or accessory
items for formwork, assembly, use and disassembly of formwork
elements. Personnel not involved in assembly or disassembly shall
not be allowed inside these delimited areas.
Storage shall be properly organized in suitable locations, away from
passageways.
All material must be properly stacked, without exceeding safe heights,
to avoid the risk of toppling or causing diffi culties when roping it for
lifting or transport. Work materials and tools must be placed or stored
so that they cannot collapse, fall or turn over.
Materials stored must be stable, arranged horizontally and wedged
in place.
Materials must not be stored on insecure slopes, unstable or loose
ground, or loose or unstable elements.
If the material is strapped, the straps should not be removed while
there are workers in its path.
Transporting Materials
There must be proper coordination between the crane worker and the
worker who hooks or guides the load. The crane worker must have a
clear view of the trajectory of the load or, failing this, must be assisted
by a guide, communicating with each other using a pre-agreed set of
signals.
Before starting load hoisting, the worker must move away from the
sweep area of the load. When the load is moving, no worker shall
be on it, and movements above or near people should be avoided.
The presence or passage of people under suspended loads must be
avoided.
The load must be well balanced and must be raised and lowered
slowly, avoiding abrupt acceleration and deceleration.
Loads must be lifted vertically, never diagonally, avoiding rocking and
horizontal dragging movements. When necessary, guide ropes or
cables adequate for the load being supported must be used for this
purpose.
When lifting heavy or bulky loads, the use of rocker arms is
recommended.
If the loads could collide with the structure, other on-site elements or
personnel, retention or load-guiding cables should be used.
