GENERAL RISKS

– Falls at different level

– Collapse of the structure

– Knocks from falling objects

– Falls at the same level

– Direct or indirect electrical contacts

PRECAUTIONARY MEASURES

Scaffolds should be projected, mounted and maintained conveniently so as to prevent them from accidentally collapsing or shifting.

Work platforms, walkways and scaffolding ladders should be constructed, sized, protected and used in a manner that prevents people from falling or being exposed to falling objects. To this end, its measures will be adjusted to the number of workers who will use them.

– When the calculation note of the chosen scaffold is not available, or when the planned structural configurations are not included in it, a calculation of strength and stability must be carried out, unless the scaffold is mounted in a generally recognized type configuration.

– Depending on the complexity of the chosen scaffold, a plan for assembly, use and disassembly must be drawn up. This plan and the calculation referred to in the previous section must be done by a person with a university education that enables it to carry out these activities. This plan may take the form of a generalized application plan, complete with elements corresponding to the specific details of the scaffolding in question.

For the purposes of the provisions of the previous paragraph, the assembly, use and disassembly plan will be mandatory for the following types of scaffolding:

Suspended platforms of the variable level (of manual or motorized operation), installed temporarily on a building or a structure for specific tasks and lifting platforms on a mast.

Scaffolding consisting of prefabricated elements supported on the natural ground, concrete slabs, slabs, overhangs or other elements whose height, from the lower level of support to the crowning of the scaffolding, exceeds six meters or has horizontal elements that save flights and distances higher between supports of more than eight meters. The scaffolds of easels or briquets are accepted.

Scaffold Shrink Wrapping

Scaffolding installed on the outside, on roofs, domes, roofs or upper structures whose distance between the levels of support and the ground or ground level exceeds 24 meters in height.

Access towers and mobile work towers in which work is carried out more than six meters high from the point of operation to the ground.

However, in the case of scaffolding that, despite being included among the aforementioned, have the “CE” mark, as they are subject to specific regulations on commercialization, the aforementioned plan may be replaced by the specific instructions of the manufacturer, supplier or supplier, on the assembly, use and disassembly of equipment, unless these operations are carried out in a manner or under conditions or circumstances not provided for in these instructions.

– The support elements of a scaffold must be protected against the risk of sliding, either by clamping the support surface, either by means of an anti-slip device, or by any other solution of equivalent efficiency, and the supporting surface must have a sufficient capacity. It should guarantee the stability of the scaffold. The unexpected displacement of mobile scaffolds during work at height must be prevented by suitable devices.

– The dimensions, the shape and the layout of the platforms of a scaffold should be appropriate for the type of work to be carried out, be suitable for the loads that must be supported and allow them to work and circulate in them safely. The platforms of the scaffolds will be mounted in such a way that their components do not move in a normal use of them. There should be no dangerous gap between the components of the platforms and the vertical collective protection devices against falls.

– When parts of a scaffold are not ready for use, in particular during assembly, dismantling or transformation, these parts must have warning signs of general danger, in accordance with Royal Decree 485/1997, of 14 April, on safety and health signage in the workplace, and conveniently delimited by physical elements that prevent access to the danger zone.

– The scaffolding can only be assembled, disassembled or modified substantially under the direction of a person with a university or professional training that enables it for it, and by workers who have received adequate and specific training for the operations planned, which allows them to face specific risks in accordance with the provisions of Article 5, intended in particular to:

The understanding of the plan of assembly, disassembly or transformation of the scaffolding in question.

The safety during assembly, disassembly or transformation of the scaffolding in question.

The measures to prevent the risk of falling people or objects.

The security measures in case of change of weather conditions that could negatively affect the safety of the scaffolding in question.

The conditions of admissible load.

Any other risk involved in the aforementioned assembly, disassembly and transformation operations.

Both the affected workers and the person supervising will have the aforementioned assembly and disassembly plan, including any instructions that may be included.

When, it is not necessary to prepare a plan of assembly, use and disassembly, the operations foreseen in this section may also be directed by a person who has an experience certified by the employer in this matter for more than two years and has the preventive training corresponding, as a minimum, to the functions of the basic level, in accordance with the provisions of section 1 of article 35 of the Regulation of Prevention Services, approved by Royal Decree 39/1997, of January 17.

Shrink Wrap Services

– The scaffolding must be inspected by a person with a university or professional training that enables it to do so:

Before being put into service.

Next, periodically.

After any modification, period of non-use, exposure to the weather, seismic shocks, or any other circumstance that could have affected its strength or stability.

When it is not necessary to prepare an assembly, use and disassembly plan, the operations foreseen in this section may also be directed by a person who has an experience certified by the employer in this matter for more than two years and has the Preventive training corresponding, as a minimum, to basic level functions, in accordance with the provisions of section 1 of article 35 of the Regulation of Prevention Services, approved by Royal Decree 39/1997, of January 17.
