n buildings, asbestos is mainly used for fire protection, for thermal, acoustic insulation and reinforcement for concrete of buildings. In general, asbestos can be found mainly in the materials that cover sprayed surfaces (flocked), insulating pipes and boilers, and in a prefabricated material (asbestos cement). The presence of material-containing asbestos in a building is not free from hazard. It can hamper some danger to the health of the inhabitants. In fact, the health risks depend by the probability that individuals can inhale the material releases in the air asbestos fibres by accident.
