AsbestosWhat is asbestos, you ask? Well, asbestos is the name for a group of naturally occurring silicate minerals that can be separated into fibers. The fibers are strong, durable and resistant to heat and fire. They are also long, thin and flexible, so that they can even be woven. Because of these qualities, asbestos has been used in thousands of consumer, industrial, marine, automotive, scientific and construction products. During the twentieth century, approximately 30 million tons of asbestos were used in industrial sites, homes, schools, shipyards, and commercial buildings in the United States. There are several types of asbestos fibers, of which three have been used for commercial applications: (1) Chrysotile, or white asbestos, comes primarily from Canada and has been used extensively in the United States. It is white-grey in color and is found in serpentine rock. (2) Amosite, or brown asbestos, comes from southern Africa. (3) Crocidolite, or blue asbestos, comes from southern Africa or Australia. Amosite and crocidolite are called amphiboles. This term refers to the nature of their geological formation. Other asbestos fibers that have not been used commercially are tremolite, actinolite, and anthophyllite, although they are sometimes contaminants in asbestos-containing products. What are products containing asbestos? What many asbestos-containing products have in common is that they were used to contain heat (i.e. for thermal insulation). It is impossible to list all the products that, at one time or another, have contained asbestos. Some of the most common products containing asbestos are pipe liners, insulating cement, insulating blocks, asbestos fabrics, gaskets, patching materials, thermal seals, refractory and boiler insulation material, transit panels . Other materials include asbestos-cement pipes, fire-retardant sprays, joint compounds, vinyl floor tiles, ceiling tiles, mastics, adhesives, siding, acoustic structures, installation of ductwork for heating, ventilation and air conditioning systems, roofing products, insulated electrical cables and panels, and brake assemblies and fabrics. Some of these products contained a very high percentage of asbestos, while others contained small amounts. Some people may wonder why asbestos is still a problem. Well, asbestos is still a problem. It is because it has been used largely in the United States and elsewhere. Also because man... at the center of the paper... there is the fibre. It is important not to release fibers into the air or onto yourself when taking samples. Only you should be in the room when sampling is completed. Asbestos repair. Where and how to repair asbestos is different in all places. Pipe, Furnace and Boiler Insulation: When the insulation material moves when touched by the hand or the covering is no longer solid and tight, the insulation is probably too deteriorated to be repaired. For material in these conditions call a professional. Repair by the homeowner should be attempted, if at all, where the insulation is sound and the covering airtight, and there should be a minimum of holes or tears in the insulation (e.g., no more than an inch of opening diameter in four linear lines). feet of tube cover). For minor damaged areas like this, you can get commercial products designed to fill holes and seal damaged areas in asbestos pipe insulation. These products are available from security store vendors. Bottom line, asbestos is not something you want to mess with. It is very dangerous for health and life. If you have asbestos, don't mess with it;.
