Vanderbilt began talc operations at the Couverneur Tale Company in 1947 with one mine 21 and one mill 21 In 1974 the Vanderbilt Corporatio acquired all talc operations of the International Tale Company From this purchase Vanderbilt was operating two mills # and 6 one underground mine # mine and one open pit Arnold Pit at the time of this study Only the 3 mine contains what the Vanderbilt Corporation considers to be fibrous anthophyllite and this ore is processed in the 33 mill The total employment at all R.T. Vanderbilt New York talc operations at the time of the present study was approximately 170 persons These are broken down as follows Underground ~- 41 Open Pit ~ 13 Mills - 67 Salaried - 49 170 Employees of these operations are represented by Local 4979 of United Steel Workers which organized in these talc operations in 1954. All operations were on a 5 day per week schedule with the mine operating only during the day shift while the mill operates three shifts A list of jobs and a de- scription of related duties in the number one mine and mill are given in Appendix II Approximately 19 talc products from all of the Company's New York talc operations are marketed Mineral Product Safety Data Sheets for these products supplied by .. Vanderbilt ; are shown in Appendix I. These talcs are used in numerour products Some typical uses are as follows CRMC _ 1. Ceramic wall tile 2. Pottery artware artware 3.

Copies of the reports submitted by McCrone and Mt. Sinai and analytical data obtained by NIOSH are given in Volume II of this report These reports all concluded that asbestiform tremolite and anthophylite anthophyllite were present in tthhese ese samples In In addition Mt. Sinai and NICSH NICSH reported trace quantitiesquantities of chrysotile in some samples The only major discrepancy notable is a higher quartz content for each sample reported by Mt. Sinai NICSH aralyses tend to support the lower McCrone results which is substantiated by the air sample results Results of NIOSH electron microscopic analyses of these talcs given in Table 3 show that a majority of the fibrous particles in these samples are anthophyllite 67 to 883 with smaller quantities of tremolite 4 to 123 A large majority of the fibrous Anthophyllite by tremolite identified ray fibers withvery large large aspect diffractiodniffraction is not ratios 1000/1 were' observed A close association between talc and tremolite has been demon- stratebdy Stemple and Brindley 15 Results of further ray diffraction and petrographic microscopic analyses McCroneof product samples collected during the study are shown in Table 4.

One of the most comprehensive studies of mortality and morbidity among anthophyllite asbestos workers was reported by Meurman et.al. 32 A cohort of 1092 workers who had worked at least 3 months between January 1936 and June 1967 was obtained obtained obtained obtained obtained obtained from from from from two mining operations one of which produced anthophyllite asbestos and the other produced mainly tremolite talc For calculation of expected age cause specific deaths proportional rates for Finland were used for 1958 which was the median year of death for these workers In addition a control group matched for date of birth and sex was chosen from a locul population registry of the 1092 employees 248 deaths were observed Thirteen deaths due to asbestosis were observed for the cohort and none in the controls Twenty one lung cancers were observed in the worker cohort versus 13 in the control group The most significant cancer risk was observed in those with ten or more years of These authors adjusted lung cancer rates for smoking exposure habits and concluded that a smoking asbestos worker had a re- lative risk of 1.4 whereas the smoking asbestos worker had a relative risk of 17.0 No cases of mesothelioma were reported All of the above epidemiological studies of workers exposed to fibrous tremolite or anthophyllite have demonstrated an excess risk of both pneumoconiosis and lung and pleural cancer No evidence of an excessive risk of mesothelioma 000340 CRMC among such exposed workers has yet been demonstrated however an excessive incidence of pleural changes including pleural calcifications have been ob- served in chest films CRMC CONCLUSIONS AND RECOMMENDATIONS Results of the present industrial hygiene study show numerous operations in both the number one mine and mill to have excessive exposures to air- borne fibers Analyses of both bulk tales samples and airborne dust samples by analytical electron microscopy have shown that a majority of these fibers are asbestiform tremolite and anthophyllite Based on these studies and on exhaustive review of the epidemiological literature concerning health effects of such exposures it is concluded that immediate corrective actions to re- duce exposures must be taken as recommended in the Progress Report issued on May 25 1976. Specific actions include the following & 1 Mine ventilation should be evaluated with considerations for increasing air volume and distribution Water sprays should be installed at the ore pockets | 2. During the present study numerous leaks were observed at material transfer points within the mill More emphasis should be placed on maintaining equipment in proper working order 3 At the packing stations ventilation improvements are needed Local exhaust hoods at these machines are located too far from the filling spout to be effective Hood designs at these machines should be further evaluated In addition bursting bags at these stations are a significant source of exposure therefore use of an should be provided with respiratory protection as spec.fied in 5. All provisions for medical examinations specified in the OSHA asbestos standard should be followed The ashestiform mineral content of products from the number one mine and mill make it imperative that these talcs be labeled with the OSHA warning label 8 61 CRMC ae REFERENCES Ross M.
