The following recount criterion is for a pair of counts that estimate AC in fibers/cc. The criterion is given at the type-I error level. That is, there is 5% maximum risk that we will reject a pair of counts for the reason that one might be biased, when the large How To Remove Asbestos Siding observed difference is really due to chance. 

Reject a pair of counts if: Where: AC1 = lower estimated  airborne fiber concentration AC2 = higher estimated airborne fiber concentration ACavg = average of the two concentration estimates (FB) = for the average of the two   concentration estimates If a pair of counts are rejected by this criterion then, recount the rest of the filters in the How To Remove Asbestos Siding submitted set. 

Apply the test and reject any other pairs  failing the test. Rejection shall include a memo to the industrial hygienist stating that the sample failed a statistical How To Remove Asbestos Siding test for homogeneity and the true air concentration may be significantly different than the reported value. 7.4. Reporting Results Report results to the industrial hygienist as fibers/cc. 

Use two significant figures. If multiple analyses are performed on a How To Remove Asbestos Siding sample, an average of the results is to be reported unless any of the results can be rejected for cause. 8. References 8.1.

Quality Control The OSHA asbestos regulations require each laboratory to establish a quality control program. The following is presented as an example of how the OSHA-SLTC constructed its internal curve as part of meeting this requirement. Data is from How To Remove Asbestos Siding samples collected during OSHA compliance inspections and analyzed from October 1980 through April 1986. 

Each sample was counted by 2 to 5 different counters independently of one another. The standard deviation and the statistic was calculated for each sample. This How To Remove Asbestos Siding data was then plotted on a graph of vs. fibers/mm(2). A least squares regression was performed using the following equation: where: Application of least squares gave: 

Using these values, the equation becomes: Sampling Pump Flow Rate Corrections This How To Remove Asbestos Siding correction is used if a difference greater than 5% in ambient temperature and/or pressure is noted between calibration and sampling sites and the pump does not compensate for the differences. 

(For Equation D, ) Where: Q(act) = actual flow rate Q(cal) = calibrated flow rate (if a rotameter was used, the rotameter value) P(cal) = uncorrected air pressure at calibration P(act) = uncorrected air pressure at sampling site T(act) = temperature at How To Remove Asbestos Siding sampling site (K) T(cal) = temperature at calibration 

Graticule When ordering the Graticule for asbestos counting, specify the exact disc diameter needed to fit the ocular of the microscope and the diameter (mm) of the circular counting area. Instructions for measuring the How To Remove Asbestos Siding dimensions necessary are listed: (1) 

Insert any available graticule into the focusing eyepiece and focus so that the graticule lines are sharp and clear. (2) Align the microscope. (3) Place a stage micrometer on the microscope How To Remove Asbestos Siding object stage and focus the microscope on the graduated lines. (4) Measure the magnified grid length, PL (um), using the stage micrometer. 

Remove the graticule from the microscope and measure its actual grid length, AL (mm).  This can be accomplished by using a mechanical stage fitted with verniers, or a jeweler's loupe with a direct reading scale. (6) Let D = 100 um. Calculate the  How To Remove Asbestos Sidingcircle diameter, d(c)(mm), for the Walton-Beckett graticule and specify the diameter when making a purchase.

Each eyepiece-objective-reticle combination on the microscope must be calibrated. Should any of the three be changed (by zoom adjustment, disassembly, replacement, etc.), the  How To Remove Asbestos Siding combination must be recalibrated. Calibration may change if interpupillary distance is changed. 

Measure the field diameter.acceptable range: 100 plus or minus 2 um) with a stage micrometer upon receipt of the graticule from the manufacturer. Determine the How To Remove Asbestos Siding field area. The Graticule is available from: Graticules Ltd., Morley Road, Tonbridge TN9 IRN, Kent, England (Telephone 011-44-732-359061).
