Prcj ect No. 5617 EYGZIA LMC. 1. iirrscDucricH The objective of this investigation was to determine levels of airbcme asbestos fiber generated curing .the removal of worn asbestos-containing valve caching materials. These packings are press-fit into the flanges between the valve and the connecting pipe. The cachings manufactured by the A. tf. Chesterton Company contain woven chrysotile asbestos fiber impregnated with a resin. The paching is cast into a rope having a more-cr-less square cross section approximately 1/4- to 3/3-inch on a side. Over time, the resin deteriorates and, as leahs occur at the flange, the paching must be replaced with a new cr.e. This study focuses on the level of asbestos fiber released into the air during the removal of the dried asbestos woven fiber. 2. AI3S. SAMPLING PHCCSDC3SS Air samples vara collected or. JTcvember 22, 1333 at the A. W. Chesterton Wccum facility. These samples were collected in the bciler room containing two process steam boilers. Beth boilers - are insulated with asbestos lagging which appears to be completely intact and in good condition. The valve used in these tests was located on a pipe leading from the top of one of the boilers. This boiler had net been epera-ad for several years and. the paching in the valve needed replacement. In this test, a six-inch hcc watar valve (sea Appendix D) located at the top of the bciler was removed for paching replacement. The belts attaching the valve to the pipe were 'locsened and removed and the valve was pried off the paching material that was stiching to the two flanges. The valve was then lowered to the floor with an assist from a rope sling. Air monitoring was - carried out, as described below, during the removal of the paching material. It was ncted that the paching was compressed flat to approximately l/2-inch by 1/3-inch. The paching was remarkably dry and a oust was visible during the first attempt at removal. The paching was very solidly adhering to the metal fiance and had to be removed using a cold chisel cine* Air samples were collected far both, chase contrast microscopic (PCX) and analytical transmission electron microscopic (ATIM) analysis. A 25_mm mixed-cellulose ester (MCI) membrane filter having a nominal pore sloe of o.ao micrometers (un) was used for the PCM sample and a 25 mm MCI filter with a nominal pore size of 0.45 urn was used for the ATIM analysis. These cassette and pore sioes are these required for the*NIOS.K 7.40G PCM and U.S. I?A TIM methods. 1 :n 3 ec Me .

ANALYTICAL METHODS AND RESULTS Bulk Analysis of Packinc Material: Samples of the actual gasket and packing material were collected after the removal process. These samples were analyzed by the EYGZIA INC. Laboratory. The bulk samples were analyzed by polarised light microscopy (ZPA Interim Method: Appendix A to Subpart F-40 CFR Part 762) at magnifications ranging from lOx to 40Ox. The estimated phase abundances are provided in weight percent and are accurate to within 10 to 15 percent of the amount reported. This method is sensitive to the presence of asbestos to less than one percent by weight. The EYGZIA INC. laboratory is accredited by the u.S*. ZPA for asbestos in bulk samtia analysis (#1G35) and by the State of Massachusetts for asbestos analysis. This laboratory is also accredited under the National > Voluntary Laboratory Accreditation Program (NVLAP), number 1011.00, administered by the National Institute of Standards and Technology (formerly the National 3uraau|cf Standards). The results of the bulk analyses are shewn in Table 1; the laboratory worksheets are contained in Ascencix A.

The total fiber count corresponds to the National Institute of Occupational Safety and Health (NTOSH) Method 7400 for determination of asbestos fibers and should be used solely when assessing overall air quality according to the appropriate OSEA or EPA standards. The asbestos fiber percentage refers to these larger fibers (on the filter wedge sample) which could be positively identified as asbestos by polarized light microscopy. The asbestos fibe percentage given is qualitative only and represents an estimate percentage of the total fibers cn the filter wedge which coul be identified as asbestos. This value should be used as supplementary information for assessing currant air quality and is net to be used above for determining compliance with regulatory air quality standards.

Project Nc. 5517 EYGEIA INC Analytical Transmission Electron Microscopic Analysis ef Air Samelas: A Philips Mcdel 300 Analytical Transmission Electron Microscope (ATZM) equipped with a non-dispersivs X-ray spectrometer and having electron diffraction capability was used for the analysis. The analytical method used was a modified version of the United State Environmental Protection Agency (u.S. EPA) "Methodology for the Measurement of Airborne Asbestos by Electron Microscopy", Level III, Contract No. 53-02-3255. The modifications involved counting an area of the filter to achieve analytical sensitivity of 0.005 structures per cubic centimeter as required by the "Asbestos-Containing Materials in Schools; Final Rule and Notice" 40 CFR Part 763 (Appendix A to Subpart E) . According to this regulation a building space is deemed to be free of asbestos ^f there are fever than 70 structures per square millimeter (s/mm2. Asbestos fibers are identified by their aerpheiegy, chemical composition and selected .Electron Diffraction (SAID) patterns. Photos of the morphology were taken for each sample containing asbestos structures for documentation. The results expressed in units of fibers per cubic centimeter (f/cc) and nancgrams per cubic aetar (r.c/m3) of air are reported - Table 3 _ and the complete computer printout cf the analyses is contained in Appendix 3.

DISCUSSION 07 RZSCLT AND CONCLOSICNS The bulk sample analyses indicate there to be apprcximatalv 45 ta 50 percent by weight chrysotila asbestas present in the packing material. The packing material, when new, is encapsulated in a resin; however, as the packing ages in place seme resin is removed to expose a braided asbestas rape when the valve is dismantled. The air testing during this disassembly at the A. w. Chestertan Campany was canductad during extremely aggressive removal of the gaskat from the flange. The boiler unit had net been operated for several months and the leaking gaskat, which was the subject of this test, had dried and hardened in the flange. To part the valve flange from the mating pipe flange, considerable force was applied to disconnect the tvc. There was a visible dust when the tvc parts were separated. A cold chisel and hammer had to be used ta peel the dried gaskat from the groove of the flange. This last operation represents the greatest prapertian of the sampling time. The personal sample was cailectad from the breathing zone cf <he mechanic who removed the gaskat from the flange. The dual sampling unit, collecting both phase contrast and ATZh samples was hand held within a few inches cf the mechanic's nesa and mouth. The duration cf this work was less than 15 minutes. An area sample was collected in the vicinity cf the valve as it was being removed from, the pipe flange. The cassette was placed at a distance of about one fact, from the flange itself. Beth phase contrast and an ATZh background air samples were ' col lactsd in the boiler room before any tasting activiti.as began in that space. Filter blanks, (i.e ., unexpesed filters) yielded no fibers cn microscopic analysis. The phase contrast analytical results are at the limit of detection for the volume cf air that was collected^ The total airteme fiber concentration was exceedingly low ar.d well below the Permissible Exposure Limit (PEL) cf 0.2 f/co currently enforced by the Occupational Safety ar.d Health Administration (QS:-:a; . The lew airborne fiber concentration and the short duration cf the w~rk comb ins to give an ever, lower time-weighted average exposure. EEGIIA INC -o-tcje Nc. 5617 'GZIA INC. The ATZN results are a mere "absolute" in the assessment of actual airborne asbestos fiber concentrations. Unlike the chase contrast method, used for enforcement of the occupational standard, which is based on the total fiber count, the ATZM results are based on actual asbestos fibers. Hera -again the airborne fiber concentrations are exceedingly lew and, in fact, the asbestos structures seer, were non respirable. All the asbestos-containing artifacts that were observed on the filters are shewn in the Figures in Appendix E. Four filters were analyzed using phase contrast microscopy acc--riing to the NICSH 7400 method. The results are as follows. A backrrcur.d sample taker, before any activity tock place gave a fiber count of less than 0.01 fiber per cubic centimeter (f/cc). Nc asbestos fiber could be detected. During gasket removal the fiber count was 0.01 f/co. Curing packing removal the fiber count was less than 0.01 f/co. Finally, a personal sample collected during the whole operation gave a finer count of 0.01 f/cc. This operation included pulling the cate valve away from the flange, and the removal cf both packing and gasket materials _using a cold chisel. The total elapsed time for this operation was about 20 minutes.. Four air samples were collected for analysis by analytical transmission ` electron microscopy (ATEH), with the following result. A background sample collected ever a period cf 50 minutes gave an asbestos, structure count cf less than 0.005 structures per cc. That is, no asbestos fiber was found at'the limit cf detection. During packing removal, an asbestos structure count cf 0.05 structures per cc was found. During gasket removal, the asbestos structure count was 0.005 structures per cc. These samples represent airborne fiber concentrations in the area adjacent to .the operation.. A personal sample collected in the breathing zone of the operator gave a result cf 0.0 05 structures per cc for the duration cf the cceraticn. 5y way of explanation, ws provide the fallowing comments. The term "structures per cubic centimeter" includes individual fibers, fiber bundles, clustars and matrices. 'Referring to the to obtain selected area electron diffraction (SAZD) patterns or. tne fibers because they ware coated with resin. Fiber EYGZIA INC . Project No. 5517 EZGZZA INC. Tiie short duration of the dismantling operation made it; necessary to collect tiie personal samples at .a higher volumetric flew rata than is normally used. Also, a far greater Rusher cf TZh grids had to be examined in order to attain the detection limit cf O.OQS structures per cc. The computer printout attached provides individual measurements of the asbestos fiber matrices. The |photographs, we believe, are a gacd representation cf the structures observed (keeping in mind that there were very few cf them). In cur opinion, the airborne asbestos fiber concent: aticn created during the aggressive removal cf dried, spent valve packing/gasket cf the type used here is ex reedincly low. The short duration cf packing/gasket replacemej :t work (i.e., less than 13 minutes duration) also has an i npcrtar.t effa :t in reducinc alraadv lew total dose to the worker In conclusion, the results demonstrate that the asbestos fiber level is well below even the currant CSZA Standard cf 0.2 f/cc or the 0.1 f/cc action level. The shorn duration cf the werk procedure, approximately 20 minutes, further reduces the level exposure when based cn an 3-hour time-weiohead averaca. In mere "absolute" terms, the actua.1 asbestos fiber content in the air at the workers' breathing ::cne is also very small indeed. The photomicrographs included in this report depict all asbestos-containing bodies observed cn the filters. Without exception, the fibers were enclosed with:Ln larger bodies cf resin or the individual fibers were encaost:latad with resin. We believe that these fibers could net be respired deeply into the -sspiratory tract. Rather, they would be trapped in the upper bronchial tree to be raneved by muccc:Lliary action. We also infer that the cr.e single asbestos fibe r encountered was coated with resin, a fact that may affect the f:iber potency. GZIA ETC. Prcjeoi Nc- 5SI7 EZGZIA ISC.
