The environmental Safety of Asbestos in Canada There has been recommendation in Canada to assess the safety of asbestos. The recommendation came as a response in opposition the proposed opening of Jeffery mine-an asbestos Canada town.
Asbestos Canada like all asbestos occurs naturally as a mineral in the earth’s surface. It contains strong fibers that are resistant to fire, is highly durable and was widely used in residential houses until 1978 when it was banned. Fibers of asbestos are very thin and in fact are more than 150 times thinner than the human hair. They can even float in air and not be visible to the eye thereby making it easy to be inhaled. Scientifically, it has been shown that living in a building that has materials made of this fiber is not harmful except it is damaged or disturbed. It may be difficult to notice products within your home that are made of these materials by just looking. However you may identify them because they are bound in a few products that were once used in the construction industry. These two ways may be helpful in identifying them: Firmly bound or bonded asbestos Canada is a fiber cement product that is embedded firmly in a cement medium that is hardened however new fibers especially those made of cellulose are now used today as replacement and you can find them around homes that have been built before the 1970s in some of the following materials: vinyl floor tiles, textured paints, plaster patching mixtures, the backing of vinyl floor coverings, flat or corrugated sheeting, roof shingles, limitation brick siding and water or flue pipes. The loosely bound asbestos is described as friable. This type is found in older types of household insulations used on heater, stoves and ceiling insulation materials. But today they have replaced by glass fibers. You do not need t panic when you find materials containing asbestos as you may even leave the materials in place. For instance if there is an internal sheet walls made of them and the sheet walls are in good condition and possibly coated with paint, then there is no cause for alarm as there is no health risk posed and the external cement roofs and siding may not have need to be replaced except their surfaces are damaged or are broken. Furthermore cement construction products can be disposed or removed safely provided you take the proper precautions in order to prevent the release of the poisonous dusts
However as stated earlier asbestos Canada is not exempted from danger every asbestos possess to people when it is exposed or disturbed, which happens especially during renovation and it is quite costly to remove because the procedure is no ordinary one that should be handled by individuals whenever they wish. It is mandatory to get the attention state licensed technicians who will handle the processes in a specially sealed environment. Also the removal may be dangerous since if done improperly may contaminate the air further. Encapsulation which is the sealing off the disintegrated materials may be good alternative method or control.
