Due to its activities in China, SEFTIM has been invited by CMA to participate to a workshop with the aim to determine the best protection solutions for the Potala Palace in Tibet. A 3 days trip in Tibet has allowed to visit this historical monument and determine its specificities:
- The walls are made of stone covered by insulating material.
- The roof has a wooden structure and there are many wooden poles inside the structure. A lot of flammable material such as books, carpets, electrical circuit. A significant fire risk will be considered
- Soil is very far and can be seen only on the back side of the Palace. So making an earthing system will be a challenge and the distance between rods and earth will be long with a large separation distance).
Visiting the site is rather difficult due to the reduction of oxygen content (-40%) at this altitude and the quite numerous staircase both inside and outside of the structure.
