Asbestos containing building materials

Asbestos may be released to indoor or outdoor air as a result of the disturbance of asbestos-containing building materials such as insulation, fire-proofing material, dry wall, and ceiling and floor tile. Amphibole asbestos has been found in some sources of vermiculite that has been used as home and building insulation. Workers or homeowners involved in demolition work or asbestos...

Ores which comprise a variety of minerals are, as a rule, heterogeneous. An ore body is usually named for the most important mineral (s) in the rock, referred to as value minerals, mineral values, or simply values. Some minerals contain metals, which are extracted by concentration and smelting. Other minerals, such as diamond, asbestos (qv), quartz (see Silicon COMPOUNDS), feldspars, micas (see Mica), gypsum, soda, mirabillite, clays (qv), etc, maybe used either as found, with some or no pretreatment, or as stock materials for industrial compounds or building materials (qv) (3). 

SRM 1868 consists of a set of two common bulk mine-grade asbestos materials chrysotile and amosite, contained in matrices simulating building materials (calcium carbonate and glass fiber), in quantities at just below the U.S. ERA regulatory limit of I %. This material is certified by weight for the quantity of each asbestos material present.

Asbestos-containing cement sheets, millboard, and paper have been used frequently in buildings when wood-burning stoves have been installed. These asbestos-containing materials were used as thermal insulation to protect the floor and walls around the stoves. On cement sheets, the label may tell the plant manager if they contains asbestos. The cement sheet material will probably not... 

In still another case, airborne asbestos is frequently qualitatively identified and/or sampled by either a licenced engineer or a certified asbestos contractors, and quantitatively analyzed by a certified laboratory. The building material, such as the insulation for the plumbing system, however, can only be removed by a State-certified asbestos contractor. The readers are referred to Section 3.6.3 for air sampling and identification of asbestos-containing materials.

Asbestos may, however, attack carpenters, electricians, plumbers, and school custodians who inadvertently disturb it. These people have to exercise due caution and use protective equipment whenever they think they may be dealing with asbestos. As for the rest of us, I don t think asbestos is much of an issue. Would I like to work in an asbestos mine No way. Would I want to be drilling through asbestos panels Uh, uh. Would I hesitate to send my children to a school constructed with asbestos-containing materials Nope. But I would like to know that an expert who has up-to-date knowledge of asbestos inspects the building periodically. And if that expert should recommend action, I would certainly not insist that it begin the next day.

The CIPE plan called for a remediation of asbestos-containing materials in the Etemit and in the ILVA steelwork factories. Ninety percent of the buildings, squares, and sites were cleared of asbestos by March 4,2000. During the remediation activities, and in coordination with the local Health Unities (ASL)), a series of control samples were collected. 915 samples were analyzed to evaluate the presence of aerially dispersed asbestos fibers in nearby locations. No values exceeding WHO limits were detected. 1044 samples and analyses from the Etemit site and 56 from the ILVA site were also collected to monitor fiber dispersion inside the area of the operations. 

In indoor air, the concentration of asbestos depends on whether asbestos was used for insulation, ceiling or floor tiles, or other purposes, and whether these asbestos-containing materials are in good condition or are deteriorated and easily cmmbled. Concentrations measured in homes, schools, and other buildings that contain asbestos range from about 30 to 6,000 fibers/m (0.00003-0.006 fibers/mL). People who work with asbestos or asbestos-containing products (for... 

Asbestos exposure in both children and adults may occur while breathing air in or near buildings (public or private) containing asbestos building materials or near asbestos-related industrial operations. Children breathe differently and have different lung structures than adults. It is not known if these differences may cause a greater amount of asbestos fibers to stay in the lungs of a...
