What is asbestos, what interventions disposal and clean-up methods

Asbestos is a group of natural mineral with a fibrous structure to separate into very thin fibers and durable, widely used in the past in various sectors from industry, until the adoption of Law 257/92 which approved the full disposal, since the inhalation of fibers released into the air poses a serious health risk. Therefore if asbestos is compact, that is, the fibers are strongly linked in a stable matrix and solid for which it is difficult to release, is not damaged and is free of abrasion and there are no particular health risks, while if asbestos is crumbly, ie which can be easily crumbled or reduced to powder by simple manual pressure, there is the danger of inhale the fibers. 

Interventions / Disposal
