Similar products from other sources may be substituted. 1. Introduction This Get An Asbestos Certification In Pennsylvania method describes the collection and analysis of asbestos. 

Bulk materials by light microscopy techniques including phase-polar illumination and central-stop dispersion microscopy. Some Get An Asbestos Certification In Pennsylvania terms unique to asbestos analysis are defined below: Amphibole: A family of minerals whose crystals are formed by long, thin units which have two thin ribbons of double chain silicate with a brucite ribbon in between. 

The shape of each Get An Asbestos Certification In Pennsylvania unit is similar to an "I beam". Minerals important in asbestos analysis include cummingtonite-grunerite, crocidolite, tremolite-actinolite and anthophyllite. Asbestos: A term for naturally occurring fibrous minerals. 

Asbestos includes chrysotile, cummingtonite-grunerite asbestos (amosite), anthophyllite asbestos, tremolite asbestos, crocidolite, actinolite asbestos and any of these Get An Asbestos Certification In Pennsylvania minerals which have been chemically treated or altered. The precise chemical formulation of each species varies with the location from which it was mined. 

Nominal compositions are listed: Chrysotile, Crocidolite (Riebeckite asbestos), Cummingtonite-Grunerite asbestos (Amosite), Tremolite-Actinolite asbestos, Anthophyllite asbestos, Asbestos Fiber: A fiber of asbestos meeting the criteria for a fiber. Aspect Ratio: The ratio of the Get An Asbestos Certification In Pennsylvania length of a fiber to its diameter usually defined as "length : width", e.g. 3:1. Brucite. 

A sheet mineral with the composition Mg(OH)(2). Central Stop Dispersion Staining (microscope): This is a dark field microscope technique that images particles using only light refracted by the Get An Asbestos Certification In Pennsylvania particle, excluding light that travels through the particle unrefracted. 

This is usually accomplished with a McCrone objective or other arrangement which places a circular stop with apparent aperture equal to the objective aperture in the back focal plane of the microscope. Cleavage Fragments: Mineral particles formed by the comminution of minerals, especially those Get An Asbestos Certification In Pennsylvania characterized by relatively parallel sides and moderate aspect ratio. 

Differential Counting: The term Get An Asbestos Certification In Pennsylvania applied to the practice of excluding certain kinds of fibers from a phase contrast asbestos count because they are not asbestos. Fiber: A particle longer than or equal to 5 um with a length to width ratio greater than or equal to 3:1. This may include cleavage fragments. (see section 3.5 of this appendix). 

Phase Contrast: Contrast obtained in the microscope by causing light scattered by small particles to destructively interfere with unscattered light, thereby enhancing the visibility of very small Get An Asbestos Certification In Pennsylvania particles and particles with very low intrinsic contrast. 

Phase Contrast Microscope: A microscope configured with a phase mask pair to create phase contrast. The technique which uses this is called Phase Contrast Microscopy (PCM). Phase-Polar Analysis: This Get An Asbestos Certification In Pennsylvania is the use of polarized light in a phase contrast microscope. It is used to see the same size fibers that are visible in air filter analysis. 

Although fibers finer than 1 um are visible, analysis of these is inferred from analysis of larger bundles Get An Asbestos Certification In Pennsylvania that are usually present. Phase-Polar Microscope: The phase-polar microscope is a phase contrast microscope which has an analyzer, a polarizer, a first order red plate and a rotating phase condenser all in place so that the polarized light image is enhanced by phase contrast. 

Sealing Encapsulant: This Get An Asbestos Certification In Pennsylvania is a product which can be applied, preferably by spraying, onto an asbestos surface which will seal the surface so that fibers cannot be released. Serpentine: A mineral family consisting of minerals with the general composition  having the magnesium in brucite layer over a silicate layer. 

Minerals important in asbestos analysis included in this family are chrysotile, lizardite, antigorite. 1.1. History Light microscopy has been used for well over 100 years for the determination of mineral species. This Get An Asbestos Certification In Pennsylvania analysis is carried out using specialized polarizing microscopes as well as bright field microscopes. 

The identification of minerals is an on-going process with many new minerals described each year. The first recorded use of asbestos was in Finland about 2500 B.C. where the Get An Asbestos Certification In Pennsylvania material was used in the mud wattle for the wooden huts the people lived in as well as strengthening for pottery. 

Adverse health aspects of the mineral were noted nearly 2000 years ago when Pliny the Younger wrote about the poor health of slaves in the asbestos mines. Although known to be injurious for centuries, the first modern Get An Asbestos Certification In Pennsylvania references to its toxicity were by the British Labor Inspectorate when it banned asbestos dust from the workplace in 1898. 

Asbestosis cases were described in the literature after the turn of the century. Cancer was first suspected in the mid 1930's and a causal Get An Asbestos Certification In Pennsylvania link to mesothelioma was made in 1965. Because of the public concern for worker and public safety with the use of this material, several different types of analysis were applied to the determination of asbestos content. 

Light microscopy requires a great deal of experience and craft. Attempts were made to apply less subjective Get An Asbestos Certification In Pennsylvania methods to the analysis. X-ray diffraction was partially successful in determining the mineral types but was unable to separate out the fibrous portions from the non-fibrous portions. 

Also, the minimum detection limit for asbestos analysis by X-ray diffraction (XRD) is about 1%. Differential Thermal Analysis (DTA) was no more Get An Asbestos Certification In Pennsylvania successful. These provide useful corroborating information when the presence of asbestos has been shown by microscopy.

However, neither can determine the difference between fibrous and non-fibrous minerals when both Get An Asbestos Certification In Pennsylvania habits are present. The same is true of Infrared Absorption (IR). When electron microscopy was applied to asbestos analysis, hundreds of fibers were discovered present too small to be visible in any light microscope. 

There are two different types of electron microscope used for asbestos analysis: Scanning Electron Microscope and Transmission Electron Microscope. Scanning Electron Microscopy is useful in identifying minerals. The can provide two of the three pieces of Get An Asbestos Certification In Pennsylvania information required to identify fibers by electron microscopy: morphology and chemistry. 

The third is structure as determined by Selected Area Electron Diffraction -- SAED which is performed in the. Although the Get An Asbestos Certification In Pennsylvania resolution of the is sufficient for very fine fibers to be seen, accuracy of chemical analysis that can be performed on the fibers varies with fiber diameter in fibers of less than 0.2 um diameter. 

The is a powerful tool to identify fibers too small to be resolved by light microscopy and should be used in conjunction with this method when necessary. The can provide all three pieces of Get An Asbestos Certification In Pennsylvania information required for fiber identification. 

Most fibers thicker than 1 um can adequately be defined in the light microscope. The light microscope remains as the best instrument for the determination of mineral type. This is because the minerals under Get An Asbestos Certification In Pennsylvania investigation were first described analytically with the light microscope. 

It is inexpensive and gives positive identification for most samples analyzed. Further, when optical techniques are inadequate, there is ample indication that alternative Get An Asbestos Certification In Pennsylvania techniques should be used for complete identification of the sample.
