What is a mobile scaffolding
The mobile scaffolding, also known as the scaffolding or tower wheeled bridge, is a construction composed of metal pipes and wooden and metal boards. This equipment is used to perform high-level masonry work, or to allow painting and painting operations both inside and outside buildings. The mobile scaffoldings are scaffoldings that must have a very wide base able to withstand the loads and also the eventual oscillations caused by the strong wind. The mobile scaffolding of reduced dimensions has wheels that allow it to be easily moved and suitable locking elements to prevent them from moving during the execution of the work. In addition to being homologated, large-scale mobile scaffolds must be locked to the building every two floors and their slope must be checked with a level.
What risks do mobile scaffoldings entail?
Analyzing all the incidents that occurred using mobile scaffolding, statistics were created from which it emerged that the risks to which workers are most exposed are: the risk of falling from a height and the risk of overturning the bridge that constitutes the mobile scaffolding. The risk of overturning occurs when the scaffolding is not anchored to the ground and to the building or when the wheels have not been properly locked. As for the fall from above, the causes can be of various types, such as the failure of the base with the consequent collapse of the scaffolding, or the absence of parapets. Among the other causes there were fractures of the boards used to create the walkways, displacement of the scaffolding without taking into account the presence of people working and finally the non-use of PPE, or personal protective equipment.
Proper use of mobile scaffolding
Let's see together how mobile scaffolding should be used correctly. The first thing to specify is that on the scaffolding there must be no other structures such as stairs or trestles. Furthermore, the height of the external mobile scaffolding must never exceed the height of the building itself. Before installing a scaffolding, it is always better to contact a surveyor or engineer if you are not very practical. As already specified it is very important that the base is solid to support the loads and to avoid collapses during movement. For all mobile scaffolding, technical safety data sheets are provided for the assembly which also contain information on the material to be used, which must be CE marked. For companies operating in the building sector, training courses have been set up by accredited bodies and at the end of which a certificate is issued. The importance of PPE is also explained during the course. For a correct use of the scaffolding, even before starting work, the helmet must be worn and the belts and straps to be tied to the structure must be in place to prevent the risk of accidental falls.
Mobile scaffolding: Mobile scaffolding guidelines
We have already anticipated that for the correct use of scaffolding it is necessary to wear personal protective equipment. Now let's discover together the guidelines to get to work on a scaffolding in total safety. First of all, you should never climb on the external structures, but use the appropriate stairs provided for access to the scaffolding. Furthermore, no materials should be thrown from above to prevent them from hitting passers-by or work colleagues. Furthermore, you should never lean over the scaffolding and avoid having too many heavy loads at the same time. The scaffolding must be installed away from electrical cables, but if the building's shape does not allow it, it is necessary to take the right precautions. Finally, after its use, clean the gangways and connecting bridges, and check that there are no structural damages.
