Myers Dear Mr. Myers: Confirming our telephone conversation of October 25th, we a re most appreciative of your offer resulting from our conversation relative to the testing of asbestos du3t samples. We have this date forwarded to your attention ten (10) separate samples which we identified as follows: Sample Number ML* s of Air 1 2 3 4 5 B - 36 B - 37 B - 38 B - 39 B - 40 150,000 150,000 114,000 96,600 21,000 118,800 87,400 113,800 91,080 91,080 We would appreciate your returning to us the remaining unused portion of the samples when you are through with your tests. As I explained to you we are getting very wide discrepancies in our testing vs. our insurance company, the state and federal government tests. These particular samples were tested initially by us then by our insurance company and we felt that with your company's expertise in this matter we may. be able to resolve the discrepancies which have cropped up* We understand that you will be unable to ship asbestos in plastic bags until some time after the first of the year. We would appreciate A 2 38 3 2 UCC 015979 on Carbide Corporation Page 2 October 27, 1-972 your advising us as soon as you are able to ship in plastic at which time our plants will consume the present paper bags and re place this inventory with plastic# Thank you for your cooperation in the above matters.

Answering lH*r dal* March 3> 1972 Mr. W. N. Johnson Mr. J. W. Rawlings Dr. J. J. Welsh/Dr. K. S. Lane Subject Dear Mr. Myers: The following is the report of the survey we conducted at American Biltrite Company plant in Trenton, New Jersey, March 1, 1972. The purpose of the survey was to obtain information on the concentration of asbestos fibers in the work environment during the use of asbestos in the manufacture of plastic tile. Samples of airborne particulates were collected on Millipore filter paper at typical work points by use of battery-powered air pumps. They were examined for fiber content by the microscopic procedure recommended in the proposed amendment of OSHA regulations. Federal Register, January 12, 1972. Results are given below. Location Fibers 5 microns or longer per milliliter of air* Inside box car during manual handling of bags of asbestos preparatory for use of fork-lift (Phillips-Carey TTS3). Beside operator on platform at Banbury ^3 (Une !) ifoperati^^ 73/iK * + Background on platform for line 2 blender (no loading of asbestos). Platform for line 2 blender while loading 18 bags of Phillips-Carey TTS3. 21^ 1^28^ 0.54 2.03 ^ Aisleway between Banbury lines 1 & 3 Aisle back of No. 2 mill. 0.75 1.41 At tile cut-out machine. 1.11 OSHA limit - 5 fibers per milliliter of air A2383b UCC 015982 Mr. J. L. Myers -2- March 3, 1972 While there was considerable visible dust in the air at most of the locations sampled, the actual fiber content was not great implying that the visible dust consisted of other tile mix ingredients. One exception in fiber count was noted during the manual handling of bags of asbestos in a box car in preparation for use of a fork-lift truck. Strangely enough, the amount of visible dust at this operation was considerably less than noted inside the plant. During operations involving the direct handling of asbestos (un loading the box car, dumping 'bag contents into blenders, removing empty bags, etc.) and for certain other operations, personnel wore paper throw away respirators that appeared to be 3M (Minnesota Mining & Milling) products. These respirators do not conform with the requirements of the proposed OSHA. amendments and therefore are not acceptable for control of exposure to asbestos. For this purpose, only respirators approved by the U. S. Bureau of Mines under Schedule 21B or the more restrictive schedules in cases of higher air concentrations of fiber are allowed. The selection of the respirator needed for any one point of exposure will depend on the concentration of asbestos encountered. Very truly yours, PWM:dp Paul W.
