Asbestos Abatement >> Remove Asbestos Tile In The Home


Minerals consist of atoms that may be arranged in random order or in a regular arrangement. Amorphous materials have atoms in random order while crystalline materials have long range order. Many Remove Asbestos Tile In The Home materials are transparent to light, at least for small particles or for thin sections. 

The properties of these Remove Asbestos Tile In The Home materials can be investigated by the effect that the material has on light passing through it. The six asbestos minerals are all crystalline with particular properties that have been identified and cataloged. These six minerals are anisotropic. They have a regular array of atoms, but the arrangement is not the same in all directions. 

Each major direction of the crystal resents a different regularity. Light photons traveling in each of these Remove Asbestos Tile In The Home main directions will encounter different electrical neighborhoods, affecting the path and time of travel. The techniques outlined in this method use the fact that light traveling through fibers or crystals in different directions will behave differently, but predictably. 

The behavior of the light as it travels through a crystal can be measured and compared with known or determined values to identify the Remove Asbestos Tile In The Home mineral species. Usually, Polarized Light Microscopy (PLM) is performed with strain-free objectives on a bright-field microscope platform. This would limit the resolution of the microscope to about 0.4 um. 

Because OSHA requires the counting and identification of fibers visible in phase contrast, the phase contrast platform is used to visualize the fibers with the polarizing elements added into the light path. Polarized light methods cannot identify Remove Asbestos Tile In The Home fibers finer than about 1 um in diameter even though they are visible. 

The finest fibers are usually identified by inference from the presence of larger, identifiable fiber bundles. When fibers are present, but not identifiable by light microscopy, use Remove Asbestos Tile In The Home either SEM or TEM to determine the fiber identity.

Advantages and Disadvantages The advantages of light microcopy are: (a) Basic identification of the materials was first performed by light microscopy and gross analysis. This provides a large base of published Remove Asbestos Tile In The Home information against which to check analysis and analytical technique. (b) The analysis is specific to fibers. 

The minerals present can exist in asbestiform, fibrous, prismatic, or massive varieties all at the same time. Therefore, bulk Remove Asbestos Tile In The Home methods of analysis such as X-ray diffraction, IR analysis, DTA, etc. are inappropriate where the material is not known to be fibrous. 

The analysis is quick, requires little preparation time, and can be performed on-site if a suitably equipped microscope is available. The disadvantages are: (a) Even using phase-polar illumination, not all the Remove Asbestos Tile In The Home fibers present may be seen. This is a problem for very low asbestos concentrations where agglomerations.

Large bundles of fibers may not be present to allow identification by inference. (b) The Remove Asbestos Tile In The Home method requires a great degree of sophistication on the part of the microscopist. An analyst is only as useful as his mental catalog of images. Therefore, a microscopist's accuracy is enhanced by experience. 

The mineralogical training of the analyst is very important. It is the basis on which subjective decisions are made. The method uses only a tiny amount of material for Remove Asbestos Tile In The Home analysis. This may lead to sampling bias and false results (high or low). This is especially true if the sample is severely inhomogeneous. 

Fibers may be bound in a matrix and not distinguishable as fibers so identification cannot be made. 1.4. Method Performance 1.4.1. This Remove Asbestos Tile In The Home method can be used for determination of asbestos content from 0 to 100% asbestos. 

The detection limit has not been adequately determined, although for selected samples, the limit is very low, depending on the number of Remove Asbestos Tile In The Home particles examined. For mostly homogeneous, finely divided samples, with no difficult fibrous interferences, the detection limit is below 1%. For inhomogeneous samples (most samples), the Remove Asbestos Tile In The Home detection limit remains undefined. 

NIST has conducted proficiency Remove Asbestos Tile In The Home testing of laboratories on a national scale. Although each round is reported statistically with an average, control limits, etc., the results indicate a difficulty in establishing precision especially in the low concentration range. It is suspected that there is significant bias in the low range especially near 1%. 

EPA tried to remedy this by requiring a mandatory point counting scheme for samples less than 10%. The point counting procedure is tedious, and may introduce significant biases of its own. It has not been incorporated into this Remove Asbestos Tile In The Home method. 1.4.2. The precision and accuracy of the quantitation tests performed in this method are unknown. 

Concentrations are easier to determine in commercial products where asbestos was deliberately added because the amount is usually more than a few percent. An analyst's results can be "calibrated" against the Remove Asbestos Tile In The Home known amounts added by the Remove Asbestos Tile In The Home manufacturer. For geological samples, the degree of homogeneity affects the precision. 

The performance of the method is analyst dependent. The analyst must choose carefully and not necessarily randomly the portions for Remove Asbestos Tile In The Home analysis to assure that detection of asbestos occurs when it is present. For this reason, the analyst must have adequate training in sample preparation, and experience in the location and identification of asbestos in samples. 

This is usually accomplished through substantial on-the-job training as well as formal education in mineralogy and microscopy. 1.5. Interferences  Any Remove Asbestos Tile In The Home material which is long, thin, and small enough to be viewed under the microscope can be considered an interference for asbestos. There are literally hundreds of interferences in workplaces. 

The techniques described in this method are normally sufficient to eliminate the interferences. An analyst's success in eliminating the interferences depends on proper training. Asbestos minerals belong to two Remove Asbestos Tile In The Home mineral families: the serpentines and the amphiboles. In the serpentine family, the only common fibrous mineral is chrysotile. 

Occasionally, the mineral antigorite occurs in a fibril habit with morphology similar to the amphiboles. The amphibole minerals consist of a score of different minerals of which only five are regulated by federal Remove Asbestos Tile In The Home standard: amosite, crocidolite, anthophyllite asbestos, tremolite asbestos and actinolite asbestos. 

These are the only amphibole minerals that have been commercially exploited for their fibrous properties; however, the rest can and do occur occasionally in asbestiform habit. In addition to the related Remove Asbestos Tile In The Home mineral interferences, other minerals common in building material may present a problem for some microscopists: gypsum, anhydrite, brucite, quartz fibers, talc fibers or ribbons, wollastonite, perlite, attapulgite, etc. 

Other fibrous materials commonly present in workplaces are: fiberglass, mineral wool, ceramic wool, refractory ceramic fibers, kevlar, nomex, synthetic fibers, graphite or carbon fibers, cellulose (paper or wood) fibers, metal fibers, etc. Matrix embedding Remove Asbestos Tile In The Home material can sometimes be a negative interference. 

The analyst may not be able to easily extract the fibers from the matrix in order to use the Remove Asbestos Tile In The Home method. Where possible, remove the matrix before the analysis, taking careful note of the loss of weight. Some common matrix materials are: vinyl, rubber, tar, paint, plant fiber, cement, and epoxy. 

A further negative Remove Asbestos Tile In The Home interference is that the asbestos fibers themselves may be either too small to be seen in Phase contrast Microscopy (PCM) or of a very low fibrous quality, having the appearance of plant fibers. The analyst's ability to deal with these materials increases with experience.
