  1. 1. Asbestos to ban<br />Asbestos (from Greek ἄσβεστος or asbestinon, meaning "unquenchable" or "inextinguishable")is a set of six naturally occurring silicate minerals exploited commercially for their desirable physical properties.] They all have in common their asbestiform habit, long, (1:20) thin fibrous crystals. The inhalation of asbestos fiberscan cause serious illnesses, including malignant lung cancer, mesothelioma(a formerly rare cancerstrongly associated with exposure to amphibole asbestos), and asbestosis (a type of pneumoconiosis). Long exposure to high concentrations of asbestos fibers is more likely to cause health problems, as asbestos exists in the ambient air at low levels, which itself does not cause health problems. The European Union has banned all use of asbestos and extraction, manufacture and processing of asbestos products.<br />
  2. 2. Asbestos became increasingly popular among manufacturers and builders in the late 19th century because of its sound absorption, average tensile strength, and its resistance to heat, electrical and chemical damage. When asbestos is used for its resistance to fire or heat, the fibers are often mixed with cement or woven into fabric or mats. Asbestos was used in some products for its heat resistance, and in the past was used on electric oven and hotplate wiring for its electrical insulation at elevated temperature, and in buildings for its flame-retardant and insulating properties, tensile strength, flexibility, and resistance to chemicals.<br />
  3. 3. Banned under the Clean Air Act:<br />Most spray-applied Surfacing ACM<br />Sprayed-on application of materials containing more than 1% asbestos to buildings, structures, pipes, and conduits unless the material is encapsulated with a bituminous or resinous binder during spraying and the materials are not friable after drying.<br />Wet-applied and pre-formed asbestos pipe insulation, and pre-formed asbestos block insulation on boilers and hot water tanks.<br />Banned under the Toxic Substances Control Act:<br />Corrugated paper, rollboard, commercial paper, specialty paper, flooring felt, and new uses of asbestos.<br />
  4. 4. Asbestos is to ban because it is dangerous and hazardous to people.<br />It can cause health problems , and it has a high concentration when you use this chemical.<br />
