Asbestos <br /> is resistant to destruction by heat or chemicals, and its fibers are extremely durable. These <br /> characteristics led to its use in wall insulation, paint, sprayed- or troweled-on surfacing <br /> materials, ceiling and flooring materials, pipe, boiler, and duct insulations, cement filler, <br /> and a variety of other products. Asbestos that may be crumbled by hand pressure is called <br /> "friable" asbestos. Material containing friable asbestos is considered hazardous because the <br /> fibers are easily released into the air by impact and deterioration. The inhalation of these <br /> fibers has been linked to the lung disease asbestosis, as well as lung cancer,mesothelioma, <br /> Fand other cancers. ("A Consumer Guide to Asbestos," Second Edition, California J <br /> Contractors State License Board, September 1991). <br /> { The U.S. Environmental Protection Agency banned nearly all uses of asbestos in 1977/78 <br /> for ceilings, walls, insulation, patching and taping compound, and pipe and boiler <br /> r <br /> insulation. However, the potential exists for asbestos to be present in older friable and non- <br /> friable materials. <br /> F,' No evidence of Asbestos Containing Materials was observed on the property. I <br /> 10.2 Lead-based Paint <br /> Buildings constructed prior to 1978 may have been painted with lead-based paint. When <br /> ingested or inhaled,lead constitutes a serious health hazard, especially for young children. <br /> Any renovation or demolition project which may result in disturbing lead-based paint <br /> must be completed according to federal regulations which control the release of lead dust. <br /> F Paint which will not be disturbed, but which is peeling or flaking, is also a significant <br /> hazard and should be abated utilizing proper techniques. g g cant <br />�i No evidence of lead-based paint was observed on thero er <br /> p p ry. <br /> F. <br /> 10.3 Radon <br /> Fi " <br /> Radon is a colorless, odorless, and tasteless gas that is produced by the decay of uranium <br /> and radium. This naturally occurring, radioactive gas is produced in most soil or rock.
