Actually there is 6 types of Asbestos ;)
But only 3 main ones used in Aust.
Chrysotile (White) -This is the most commonly used form of asbestos and can be found today in roofs, ceilings, walls and floors of homes and businesses. Chrysotile asbestos also was used in automobile brake linings, pipe insulation, gaskets and boiler seals.
Amosite - This is known as brown asbestos, and it originates mostly in Africa. It was used most frequently in cement sheet and pipe insulation. It can be found in insulating board (which contained up to 40 percent asbestos), ceiling tiles and in thermal insulation products. Like the other forms of amphibole asbestos, it has needle-like fibers.
Crocidolite - This is blue asbestos and its known for having the best heat resistance. Mined mostly in South Africa, Bolivia and Australia, this is seen as the most dangerous type of asbestos. Crocidolite was commonly used to insulate steam engines, and it was found in some spray-on coatings, pipe insulation and cement products.
The others are
Tremolite which can be white, green, gray and even transparent.
Anthophyllite which is a gray-brown colour
Actinolite is most often found in metamorphic
rock is is mainly a contaminant to the othe forms of Asbestos and was not used commercially.
Having being trained in Asbestos removal, and now working for Local Government in QLD I get public enquiries nearly every week, most people blow everything out of the water in 90% of the cases I see. It is the untrained and unsupervised Asbestos removal that causes all the issues. Keep suspect material wet and do not disturb.
