Ketchaa Insulation Block Dust Survey I Construction Insulation Shop Plant 511 Enclosed Is an Industrial hygiene report by Mr. R. E. Peele on the potential hazardousness of "new and Improved" "Thermobestos" insulatIon blocks submitted by the manufacturer for evaluation by band saw processing in the Construction Departawnt's Insulation Shop. The report points out that the three new and Improved" sample blocks, subjected to test conditions Identical with those In use and reported upon In torch of this year, are an improvement somewhat, but these blocks too, release q,uantitles of asbestos dust particles Into the working environment considerably above the acceptable safe limits (l.e., the T.L.V.). Therefore, definitely, the processing of "new and Improved" blocks also constitute a.hazard to " health. Paolo recooaeals that "Theraobestos" blocks not be processed in the Construction DepartEsat Insulation Shop until they meet acceptable standards and I concur fully. , Very truly yours, RJStgl Enclosure R. /Sexton, M.D. Plant Medical Director 11 IK MM * r T-J-* ' y * t\ i UNION CH8MICALS COMPANY R.

On 16 May 1962, a copy of a letter from Doctor Nale to the UCC Central Purchasing Department in New York pertaining to this subject was sent to some of the people on the above distribution list.. Undoubtedly, Johns Manville is extremely Interested In having our Construction Department use their "Thermobestos" blocks. However, I believe that possibly unnecessary pressure is being applied to us from several sources. The enclosed report by Mr. Peele includes information on an invitation for Mr. Peele to visit Manville, New Jersey, at Johns ItenviUe's expense to evaluate their industrial hygiene studies. Mr. Peele points out In this report also that he has been contacted recently Design and Construction Department at the Technical Center who have Implied that Mr. Peele should comply with Johns Manville s proposal. It is sy opinion that we should continue to do surveys, with limitations, on samples of "thermobestos" blocks that are of a new formula and are submitted to nr Construction Insulation Shop at the Institute Plant for evaluation. However, I am not In favor of Mr. Peele accepting Johns Seville's invitation and would appreciate approval or disapproval for this trip from my supervision so that Mr. Peele can be Informed accordingly.

Johns Manville "Thercotestos" Subiti '_ On 21 March 1962, an Industrial Hygiene Report, i.e., 62-IH-1-6-1, identified the existence of a hazard to health In the Construction Insulation i Shop ^r*"g such tines as when Insulation blocks manufactured by the Johns j Manville ?r"p*"y are being fabricated with exhausted band saws. It was recommended j at that tine that 18" x 36" x V "Thermobestos" insulation blocks* should not be fabricated with the existing equipment unless -- . I (a) The atmospheric dust problem could be reduced to below 20 mppcf s of air through the use of ventilation, etc., or _ , / ** - ; j (b) The producer of this product begins manufacturing an insulation j block which will not release upon fabrication with a band saw, dust j . concentrations in excess of 2D mppcf of air. ' In accordance with these recommendations, the Construction Insulation Shop discontinued almost immediately the purchase of "Thermobestos" j insulation blocks. - i On 20 JUly 1962, a second Industrial Hygiene Report, i.e., - 62-IH-2-G-1, was submitted subsequent to an evaluation of three new insulation materials supplied by the Johns Manville Company. This report concluded that these materials were improved over the original. However, the dust concentrations produced upon fabrication of these insulation blocks were substantially in excess of the recommended safe concentrations of 20 mppcf of air. Therefore, the recommendations contained in this report remained exactly as those stated in the initial report of March, 1962. . On 20 November 1962 the author was contacted by Mr. D. R. Matheny, General Formosa of the Insulation Shop, who stated that three Johns Manville representatives, i.e., Msssers. F. B. Saxer, N. Gordon, and H. Kaufman, were present and had requested' a meeting with the Plant Industrial Hygienist. This meeting was held in the lobby of Building 2, at.which time Mr. Saxer produced the accompanying copy of portions of a report submitted by the Johns Manville Industrial Hygiene laboratory located at Manville, N.J. Mr. Saxer stated that, in accordance with this report, they were not able to produce results which agreed with those contained in the reports submitted by this department. Therefore, they were concerned and interested in learning if their methods of reproducing The Johns Manville trade name for their Insulation blocks R. J. Sexton, M.D. 3 December 1962 Page 2 our environmental conditions, sampling and evaluating the dust concentrations contained therein were subject to question. At this point he stated also that this conclusion was promoted on the basis of their analysis of the atmospheric dust conditions produced by their competitors-product, (i.e., Kaylo or Item # 5AT In the report) which in no way agreed with the data submitted In the Industrial Hygiene Report** IH-62-I-G-I. <' . It was explained at this point, that this department's interest in this problem is always confined solely to the environmental conditions as they effect the health of our workers, and that no part of the Investigation should be construed as an attempt to arbitrarily promote the use of one company's product over that of another. Upon completion of this statement, Mr. Saxer proposed that Mr. D. R. Matheny and the Plant's Industrial Hygienist make a trip to Manvllle, New Jersey, at Johns Manville's expense and at a time selected by Union Carbide. This visit would be for the specific purpose of observing, scrutinizing and comparing their method of atmospheric dust evaluation with that as utilitized by the institute Plant's industrial Hugiene Department. It was Mr. Saxer's opinion that such a visit would permit a more positive approach to the problem and remove the possibility .of misunderstandings, etc., that results from written' correspondence. At this point, Mr. Saxer was assured that there would be no personal,objection on my part to the performance of such a .service. However, a proposal of this nature would have to be submitted to the Plant Manager, Mr. L. N. Dickinson,through appropriate channels before a final decision could be made. ' m conclusion, it should be stated that a phone call was received-; from Mr. F. G. Ccmerford of Design and Construction on the morning of 21 November 1962, who requested that he be brought up to date on this specific problem. This request was Immediately satislfled both by verbal explanation and by the promise that copies of both reports, i.e., 62-IH-I-G-I and 62-32-2-G-l would be mailed to him Immediately. Mr. Comerford further stated that we should not back down on our requirements, but that it probably might be wise to consider their proposal in light of the many ramifications of the problem as it affects the whole company structure, i.e., purchasing, sales, manufacturing, etc. Very truly yours, REi:gh Enclosure Robert E.

In the following month of April, three new "Thermcoestos" Insulation blocks were submitted to Plant 511 for evaluation under environmental conditions Identical with those experienced heretofore. C ritical analysis of the data obtained on th is more recent survey revealed the existence o f some degree of improvement in the dust contamination associated with the fabrication of these particular "Thermobestos" insulation blocks. However, the magnitude of the improvement did not reduce the atmospheric dust concentrations to within the reccncecded safe acceptable lim its o f 20 mppcf (m illion particles per cubic foot) of a ir . Therefore, the recommendations remain exactly as those stated in the report of the survey of torch, 1962. INTRODUCTION: It was established unquestionably, in an Industrial hygiene report submitted in torch of th is year, l . e . , Report 62-IH-l-G-l, that an inhalation hazard' to health lo produced within the Construction Insulation Shop whenever "Theraabeotos" insulation blocks are fabricated. Furthermore, i t was * recommended also that the fabrication o f "Theraobestos" insulation blocks ehould cease u n til at least one of the following two conditions are met: F irst, that the atmospheric dust problem is reduced to below 20 mppcf of air through the use o f ven tilation , e tc ., or, second, that, i f a new insulation block should be manufactured by the producer o f "Theraobestoc" blocks that, i t would be subjected to testin g under identical conditions as before thereby establishing the fact that i t w ill not release, upon fabrication with a band sow, dust concentrations in excess of 20 mppcf of a ir . The Industrial Hygiene Department's reconsnendatIons met exact compliance by those responsible persons in the Construction Insulation Shop, in that no "Theraobestos" insulation blocks have been fabricated with band saws for use in th is plant since the date of the issuance of these recommendations. However, some change In procedure was Indicated when, cn 25 April 1962, t h i s . department wan contacted by Mr. D. R. Matheny, General Foreman of the Insulation Shop. At that time, .Mr* Matheny requested an evaluation of a new "Theraobestos0 insulation block which had been developed by the manufacturer, In an effort to comply with the specifications as stated in the second part of the above lis te d recommendations. Insulation Block Dust urvey, Construction Insulation Shop, Plant 511, Report 62-IH-l-G-l. DISCUSSION: Mr. Matheny's request for services was immediately acted upon at which time two basic decisions were made: F irst, Friday, the 27th of April, would be the most opportune time for obtaining the infcrcation needed in the performance of th is evaluation and, second, two atmospheric dust samples of each condition should be ob:r.ined with each one being taken in identical locations so as to provide greater r e lia b ility . These sampling plans had to bo altered somewhat, however, on the s it e , when i t was discovered that the manufacturer had provided only three inculation blocks each o f which differed in the precise manner in which i t had been produced*. Ib is shortage of material, with identical characteristics, complicated the sampling and evaluation procedures somewhat, since i t was impossible, therefore, to obtain more than one sample of atmospheric dust being produced by any one material (in actuality, a to ta l of only three atmospheric dust samples were collected during the te s t period). However, th is complication van cot so severe no to render the sample data o f no use, as is revealed in the condensed explanation of the sampling procedure selected on this date which is as follows: First : The data contained on page 8 of Report 62-IH-1-6-1 revealed clearly that the greatest concentrations of atmospheric dust were produced at the band saws, and that location #3, i . e . , #2 band saw while sawing, d efin itely provided the greatest hazard to health. ` Consequently each of the three samples, under consideration in th is report, i . e . , 62-IH-2-G-1, were taken at th is same location. . - Secondi A ll of the results revealed in the preceding report, i . e . , 52-H-1-C-1, were obtained during the la te f a ll and winter, therefore, th doors to the building were closed for purposes of heat consor vatlon. These environmental conditions were duplicated during the performance of th is second survey. . Third: The operator of the #2 band saw employed sawing techniques . as nearly Identical with those in evidence during the preceding periods of evaluation as vere possible to duplicate, i . e . , position of the block with respect to the saw blade, speed of feeding the block into the saw blade, position of the operator's head with respect to the block, etc. Fourth: Each o f the dust samples obtained during the time o f performing the in itia l survey were held in the operator's breathing zone. This feature was also duplicated for this second survey, i . e . , 62-IH-2-G-1. EVALUATION: Each of the three samples collected were evaluated in the laboratory in ` accordance with recommended and prescribed ligh t field microscopic counting techniques as referred to and identified in Report 62-IH -l-G-l. It should be noted that no effo rt was expended to obtain anything more than a knowledge o f the concentration of dust in the a ir since the composition ami particle size of th is material should not be expected to deviate to any degree from the prior recorded valueo. This supposition was based on two facts, (1) the accordance with infarmation received from the manufacturer eacn block was composed o f Identically the earns materials and was formed in the same general manner, i . e . , by the "Pan Method". However, the sim ilarity in production differed from here oa with the manufacturer :elng the only one in possession of the exact description and the sp ecific a lte r cos Incorporated In each method. 3. chemical make up of these materials vas reported as being Identical with the "Thermobestoa" materials reported on in the prior survey and, (2) the saving techniques utilized on both occasions vere Identical in nature. PROCEDURES: Both sampling and analytical methods vere identical in detail with those described in the earlier report, with sampling being accomplished through . the use of the Mine Safety Appliance Company's Midget Implnger Pump and Apparatus ami the analysis taking place in accordance with light field microscopic counting techniques. f RESULTS: Analysis of the physical data contained on page 5 reveals that the ' atmospheric dust concentration in mppcf (million particles per cubic foot) of air for each of the three nev materials vas ~ (a) 36.8 mppcf of air for J.M. #21, (b) U8.1 mppcf of air for J.M.#22, and (c) W*.l mppcf of air for J.M. #23* CONCLUSIONS: (1) None of these three samples revealed a concentration as high as that recorded in the previous report for "Theraobestos" exposures in this position, i.e., 101.U mppcf of air for Location #3* Hovever, by the same token, none of the present three samples revealed a concentration as lov as that recorded for "Kaylo" exposures In this position, i.e., . 17.1 mppcf of air for Location #3* . ` (2) Each of the three values exceeded the established T.L.V. (Threshold Limit Value) of 20 mppcf of air by a substantial amount. (3) None of the three Insulation materials, i.e., J.M.#21, J.M.#22, and J.M.#23, as submitted by the manufacturer of "Thermobestoa", should be fabricated vlth band save In the Insulation Shop by our employees unless the manufacturer complies exactly vlth the following conditions: The physical and/or chemical characteristics and composition of these materials are improved to the degree that some further future evaluation wight reveal them to be Incapable of releasing concentrations of dust into the atmosphere that are in excess of the T.L.V. RECOMMENDATIONS: Do not fabricate the 18" x 36" x k" "Thermobestos" Insulation blocks (J.RTjp21, J.M.#22, J.M.#23) V i t h existing equipment unless - (1) The producer of this material can further Improve h is product to the , point tat it vill not release, upon fabrication vith our ventilated band sbits dust concentrations in excess of 20 mppcf of air, or, u.
