Asbestos - Use

sbestos has caught the attention of some industrial in the late XIXth century for its resistance to heat, fire, tension, electrical and chemical attacks, as well as its absorbency capabilities.

In its friable form, it has been used in many heat insulations and sprayed coatings, as well as sheets, felts, glues, sealants, cardboard plates, or braided or woven.

It is also found (not friable form) incorporated in cement products (asbestos cement) or in various binders (glues, paints, gaskets, plaster based mortar, asphalt, friction materials and even asphalt for roads or sealing ...). It has also been used for brake pads, or in boilers and electric furnaces. It has been massively used in buildings for its flame-retardant properties, insulation, flexibility, tensile strength and sometimes for its resistance to chemicals.

But because of their chemical composition and physical properties, these fibers can constitute a severe health threat. Inhalation of asbestos fibers is causing asbestosis (pulmonary fibrosis), of lung cancers, as well as cancers of the pleura (mesothelioma) and cancers of the larynx and gastrointestinal tract. The victims of these pathologies are mainly the "asbestos workers" but also people exposed to environmental and often without their knowledge.

The detection of the asbestos in the materials is based on the optical properties of the fibers, observed using the microscope under polarized light in phase contrast. The laboratories for these analyzes are approved following the Royal Decree of 31 March 1992 (Groups 2 and 6).
