When asbestos fibers are incorporated into initially non-friable products such as floor tiles, the material is less hazardous because it will not readily release fibers into the air. whether the ACM is likely to be disturbed.whether the ACM is friable, easily crumbled by hand pressure, and.The hazard asbestos poses depends on two factors: Intact undisturbed asbestos does not pose a health hazard Under certain circumstances asbestos exposure can be harmful. A copy of the asbestos survey report is accessible at Environmental Health and Safety by appointment. What asbestos-containing materials are present at SUNY New Paltz?īased on a comprehensive asbestos survey performed by an environmental consulting firm and on numerous bulk samples collected by Environmental Health and Safety, several building materials in certain locations have been identified as asbestos-containing: sprayed-on fireproofing, thermal insulation such as pipe insulation/pipe fittings, roofing materials, interior panels on fume hoods, lab bench tops, some skim coats on walls, floor tiles and associated floor tile mastic. ![]() A suspect material should be assumed to contain asbestos until laboratory testing proves otherwise. Certain non-friable materials (materials which are not easily pulverizable by hand-pressure) such as floor tiles and roofing materials may require further analysis by transmission electron microscopy (TEM). Laboratory analysis by polarized light microscopy (PLM) must be performed on the bulk samples. Bulk sampling procedures must be performed by a New York State Department of Labor-certified Asbestos Inspector. Known materials such as fiberglass, rubber, and styrofoam do not require sampling. In order to determine whether a material contains asbestos, bulk samples must be collected of the suspect material. How are asbestos-containing materials identified? The majority of asbestos containing materials was installed in buildings between 1960 and the mid-1970s. An asbestos-containing material (ACM) is defined by numerous agencies as any material containing more than one percent asbestos by weight. Asbestos has been used in more than 3,000 types of products, frequently in combination with other materials, fillers, or binders. In addition, because asbestos is naturally fibrous, it can be woven and mixed with other substances. Why was asbestos used?Īt one time, asbestos was considered the miracle fiber because of its noncombustible, non-corrosive, high tensile strength and low electrical conductivity properties. Crocidolite, Actinolite, Amthophyllite, and Tremolite asbestos were utilized to a much smaller degree in building construction. Approximately 95% of the asbestos used in building construction is Chrysotile asbestos. Amosite was used frequently on high-temperature thermal systems, such as boiler and pipe insulation. Asbestos is the common name for several naturally occurring minerals, including Chrysotile, Amosite, Crocidolite, Actinolite, Anthophyllite, and Tremolite.
