Welding rod samples were First tested for asbestos and non-asbestos fiber content by having a bulk sample o f the rod coating analyzed by Transmission Electron Microscopy (TEM) and Polarized Light Microscopy (PLM). Welding rods found to be positive for asbestos content were selected and subjected to the abrasion test. In addition, one set of welding rods found not to contain asbestos was tested as a negative control o f the experimental procedure. Testing involved bumping and rubbing two identical welding rods together in a small chamber for approximately 15 minutes while air samples were collected inside the chamber. Background air samples were obtained between each test. Abrasion Test Design Asbestos fiber release was tested using a customized Plexiglas glove box fitted with high efficiency particulate air (HEPA) filters. (See Appendix C, Figure 1.) The glove box is air tight except for access ports and filtered air intake and exhaust ports. Prior to each simulation, the glove box was thoroughly washed, and the air inside the glove box purged for 25 minutes using a high volume exhaust system. All air entering and leaving the glove box was HEPA filtered. Purging of the glove box was performed to reduce ambient particulate levels. For each set of experiments, all necessary materials were placed inside the glove box in sealed plastic bags. This included two sets o f air filters (one for the background air sample and one for the test sample), the welding rods to be tested, and clean-up materials. The air sampling pump was calibrated with a "Gilibrator" air flow calibrating device before and after all sampling using an identical calibration filter (marked for calibration only) so as not to contaminate the sampling filter with ambient air. Flow rates of approximately 12 liters per minute were used for all samples. To confirm that the air inside the glove box was free of asbestos fibers, a background air sample was collected for 20 minutes before testing each set of welding rods. Just prior to the initiation of the welding rod experiment, the air sampling pump was turned on. The two identical welding rods to be tested were then removed from the plastic bag and were bumped and rubbed against each other for approximately 15 minutes. After the rods had been bumped together for 15 minutes a small mixing fan was turned on for 5 minutes and then turned off. The mixing fan was used in order to enhance air mixing within the glove box. Air sampling was performed for a total o f 30 minutes. The glove box was cleaned, purged with HEPA filtered air, and re cleaned before being used for testing the next set of rods. All air samples were obtained using 25 mm diameter sampling cassettes fitted with mixed cellulose ester filters. Samples were analyzed for asbestos using Transmission Electron Microscopy (TEM), 40 CFR 753 Subpart E, Appendix A, and Phase Contrast Microscopy (PCM), NIOSH 7400. Welding Rods Tested The welding rods subjected to the abrasion experiment were two Hobart 6010 (batch 109), two Westinghouse 6011 (batch 107), and two partially burned asbestos containing received from Dr. James Millette of MV A. Analytical data for the rods tested arc given in Appendix A. The Westinghouse 6011 (batch 107) rods were found not to contain asbestos and were tested between the tests o f rods containing asbestos. This was done as an overall control of the testing, chamber clean-up and analytical procedures. Sample Preparation and Analysis Samples were prepared using the above protocol for the abrasion test. The flow rates and total sampling time for each filter cassette are outlined below in Tabic 1. (Cassettes 1 and 2 were used only for calibration and were not analyzed.)

They were sent via Federal Express to Materials Analytical Services in Atlanta and were analyzed there by the methods mentioned, under "Abrasion Test Design." Results Specifics of the laboratory analyses and results are included in Appendix B. For each set of asbestos containing rods tested, the phase contrast data for the test detected Fiber concentrations in excess of background. The abrasion test using the non-asbestos rod found no asbestos fibers or structures by TEM thus confirming that the chamber was free of contamination. Highest TEM concentrations were observed for the partially used rods with a concentration o f asbestos structures by TEM o f 1.231 structures/cc. The partially used welding rods were much more friable than the unused rods and generated significantly more airborne asbestos fibers. Fiber identification by TEM demonstrated that the fibers generated by the abrasion tests were chrysotile. Filter blanks and chamber background samples collected prior to each experiment did not detect the presence of chrysotile nor did the test conducted with non-asbestos containing welding rods. Therefore, the fiber concentrations measured arc the result of fibers released from the welding rods. Electron micrographs of typical asbestos structures observed in this sample are shown in Appendix B. APPENDIX A WELDING ROD COATING ASBESTOS ANALYSIS RESULTS MATERIALS ANALYTICAL SERVICES INC.

During the bumping tests within the enclosure, the used rods were found to be friable rsulting in visible dusts which accumulated on the bottom of the chamber. A sample of this dust was collected and submitted for TEM studies. Results of the TEM studies confirmed the presence of chrysotile asbestos with the concentration ranging from 1.8 to 5.5%. The mean fiber length was 3.55 micrometers with a significant proportion longer than 5 micrometers. Please call if you have questions.

Our results show that the chrysotile weight percent range w as found to range from 1.8 to 5.5% . Also, the m ean chrysotile fiber length calculated from 2 0 0 m easured structures was 3 .5 5 microns. DESCRIPTION OF SAMPLE PREPARATION AND ANALYSIS: Weight Analysis: The welding rod residue was analyzed by the Chatfield method to determine the weight percent of asbestos present. This analysis was performed as follows, 0 .1 0 2 9 g of the residue was placed in a muffle furnace and heated to 4 8 0 C for 12 hours. The sample was removed from the furnace and allowed to cool to jo o m temperature and reweighed. Sample weight after ashing was 0 .0 9 6 2 grams. The remaining residue was placed into 100 ml of 3% HCI in a 150ml Erlenmeyer flask. The solution was allowed to stir for 30 minutes and filtered through a pre-weighed 0.22/ym polycarbonate (PC) filter. The PC filter was dried in a desiccator for 24 hours at room temperature and weighed. The sample weight after the acid dissolution was 0 .0 3 7 7 g . After weighing, the remaining residue was suspended in alcohol and drop mounted onto a TEM grid and placed in a JE0L 1200X transmission electron microscope. The sample was scanned by TEM at a screen magnification of 2 0 ,00 0X . A visual estimation was made of the percent of chrysotile present versus the amount of non-asbestos particulates. These results were compared to the percent loss during both muffle furnace and acid dissolution analysis. Fiber Size Distribution: Approximately 10 mg of welding rod residue was placed in a 25ml glass vial with 15ml of alcohol. The sample was capped and shaken by hand. A 2ml sample was removed from the suspension and filtered through a 0.22pm PC filter. The filter was allowed to dry and prepared for TEM analysis using a direct preparation technique. The prepared sample grid was placed in a JEOL 1200 EX TEM and examined at a screen magnification of 20,00 0X . For the fiber size distribution, the first 200 chrysotile structures were measured for both their length and width. This data is shown in the enclosed TEM count sheets. FLOOR TILE ANALYSIS BY CHAT FI ELD METHOD Sa me l * !: :1i 2 ,:c 4 ; i I .A l v ai MUFFLE FURNACE ASHING RESULTS v vai weight (A> v i a l we i g h t , p l u s s a mol e wei pi?t \ B ' Or i g i 's i s a m p l e w s i ghc A i We i g ht o f v i a ] and. samp Vs a f t e r a s h i n g (C) Samp 1s w e i g h t a f t e r a s n i n a ( C - a ) O. 1029 -j iWi; ,LI-. 4 2 0 4 C O .0962q (WVZ) Muffle Furnace Ashing Results After Acid Dissolution P o l y c a r b o n a t e f i l t e r w e i g h t (D; F ilte r plus dry sample weight () Sample weight a f t e r a c ic d i s s o l u t i o n (E-C) Percent weight of organic material (W l - W2 1 ' 'LOO = W1 Psrcsrt w eight of do l e m i t e / c a l c i t a ( UP - W.T,) v LOO = Wi E s t i m a t e d u p p e r and Lower p e r c e n t a s b e s t o s by TSM s c a n i e r r e c weight cf asbestos LI.: _ c ; r : ;< W i W L / . $ 7t 0X5323 0.0377g (W 3 ) s 7q /f 7. we r iJhp l r.r ASBESTOS FIBER SIZE DISTRIBUTION Duke University Medical C enter Q cr -- Tl "*O 3 8 O n MAS JOB NMBER: sra G RID# # SQUARE# \ ?> S' C ? ? lo \\ \T- \3 Mp ______ Zo 2-1 Z.Z- 7.5" .
