Peele have been issued on this subject (21 March 1962 and 20 July 1962) and sent out under my signature. On 16 May 1962, a copy of a letter from Doctor Hale 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. Eowever, 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 Manville's expense to evaluate their industrial hygiene studies. Mr. Peele points out in this report also that he has been contacted recently by the Design and Construction Department at the Technical Center who have implied that Mr.'Peele should comply with Johns Manville's proposal. 'It is my 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 our Construction' Insulation Shop at the Institute Plant for evaluation. However, I am not in favor of Mr. Peele accepting Johns Manville's invitation and. would appreciate approval or disapproval for this trip from my supervision so that Mr. Peele can be informed accordingly.

This investigation took place during the morning of Thursday, 14 Nov 63, in the company of Hr; K. B.

No effort was made,-at that time; to determine the actual concentration of atmospheric dust being produced-during this, operation. It should not be necessary to perform this specific test so long as_working conditions are not altered appreciably from those.observed on this date. However, a more thoroughevaluation of these conditions will be performed if (1) it is`specifically requested, (2) employees begin.complaining about reactions such as nose bleed, etc., (3) a thicker material, i.e.,more .than two inches in diameter.is substituted for fabrication, or (4) the fabrication shop begins cutting each curved half-section from large blocks of "Carey-Temp".

Sexton, M.D. t-** Medical Department Da'* 3 December 1962 originating d-pi. Industrial Hygiene - Plant 512 4nswrmg Utie doi% Johns Manville "Thermobestos" 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 Shop during such times as vhen insulation blocks manufactured by the Johns Manville Company are being fabricated with exhausted band saws. It was recomen: at that time that 18" x 36" x U" "Thermobestos" insulation blocks* should not be fabricated with the existing equipment unless -- (a) The atmospheric dust problem could be reduced to below 20 mppcf . of air through the use of ventilation, etc., or (b) The producer of this product begins manufacturing an insulation block which will not release upon fabrication with a band saw, dust concentrations in excess of 20 mppcf of air. In accordance with these recommendations, the Construction Insulation Shop discontinued almost immediately the purchase of "Thermobestos" insulation blocks. 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 concentratic produced upon fabrication of these insulation blocks were substantially in execs 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. Mathen} General Foreman of the Insulation Shop, who stated that three Johns'Manville representatives, i.e., Messers. F. E. Saxer, N. Gordon, and H. E. Kaufman, were present and had requested' a meeting with the Flant 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 agrs with those contained in the reports submitted by this department. Therefore, they were concerned and interested in learning if theix methods of reproducing *The Johns Manville trade name for their insulation blocks ' A03078 UCC 015593 ^ R. J. Sexton, M.D. 3 December 19^2 . 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'vas promoted on the basis of their analysis of the atmospheric dust conditions produced by their competitors-product, (i.e., Kaylo cr Item 5AT in the report) which in no way agreed with the data submitted in the Industrial Hygiene Report "IH-62-I-G-1. 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 Manville, 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 r 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 wTould have to be submitted to the Plant Manager, Mr. L. N. Dickinson, through appropriate channels before a final decision could be made. In conclusion, it should be stated that a phone call was received from Mr. F. G. Comerfcrd of Design and Construction on the morning of 21 November 19^2, who requested that he be brought up to date on this specific problem. This request was immediately satisified both by verbal explanation and by the promise that copies of both reports, i.e., 62-2E-I-G-I and 62-H-2-G-1, would be mailed to him immediately. Mr. Ccmerford 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, : ^(to^3r C.

Table I gives the results of seven separate tests, including 24 breathing zone level air samples end shovs an average dust concentration of 5.2 million particles per cubic foot of air. A ''threshold Unit value" of 22 nppcf of air has been suggested. 1 When three employees, or less, hsnd-cut and apply "Eaylo" insulation, the concentration of dust is considered safe from the health standpoint; however, vith S men the dust count exceeds the IIV. It is at this phase of the operation that exhaust ventilation should be used. Excessive dust concentrations can be expected when the insulation is removed from piping and tanks, Agcin, exhaust venti lation should be used to move the_dust away from the employees, if possible; otherwise, respirators_are advised. "Zaylo" insulation contains 12 to 13% asbestos and 5.5 to 7.4% crystalline-free silica.^ This material is received in block and pipe form and the insulator measures and marks the material into appropriate sizes and cuts it with a hand saw. The insulation material is wired into position around the tank or pipe. Ihe tasks of cutting and apply ing the "Zaylo" insulation are shown in Figures 1 and 2. --- Hie air samples were collected with a.midget implnger and a Uni-jet sampler, drawing 0.1 cubic fcot of air per minute through impingc-r flaslcs containing 10 milliliters of distilled water. Bust counts, made by the Light Field Microscopic Counting Technique, appear in Table I. This study has revealed that further research work is needed to: 1. Attain an established figure for the "threshold limit value". 2. Utilise exhaust ventilation to remove the dust from the work area. 3; Determine the particle size of the asbestos fiber where the oust count exceeds 5 appef. 4. Obtain Range Finding Tests on animals exposed to different percents of asbestos fiber. 5. Continue our plant-wide study in support of these conclusions. 1.
