Hundreds of fibrous minerals can be found around the world and classified as asbestoforms. Only six of them were used on industrial scale and for practical reasons are classified as asbestos. Some of them are very common and some are extremely rare. Among all samples tested positive for asbestos by our laboratory, 90% contain Chrysotile, 5% are Amosite, 5% Tremolite or Actinolite, 0.2% Crocidolite, and Anthophyllite is seen in less than 0.1% of all samples.
The “popularity” of Chrysotile can be explained by its unique properties: lightweight, non-flammable, suitable for making yarn and cloth, chemically inert, and so cheap that it can be used in construction materials. It used to be a “wonder mineral”. It took 30 years to recognize that the “wonder” is toxic.
Amosite has absolutely unique heat resistance and was mostly used as insulation material for furnaces. From time to time, we find Amosite in ceiling tiles and pipe insulation.
Tremolite and Actinolite were used only occasionally. They would be out of scope of our discussion, but unfortunately, they are natural contaminants of Vermiculite, which was widely used as insulation material for industrial and residential buildings.
If your building (house) was built before 1982, it may contain asbestos in construction materials.
Call us to discuss your renovation or demolition project prior starting it. It is easy and affordable to test for asbestos. Stay safe!!!!!
