Carolina . CHARLOTTE WORKS P. O. BOX 105 16 charlotte, north caroiinj MANUFACTURERS OF SOUTHERN ASBESTOS PRODUCTS __ SUBJECT: Routine Atmospheric Hast Survey - Kay 2l;-25, 1959 We appreciate very much the copy ve have received of your technical report and analytical results on the dust counts made in our plant on Kay 21;th and 25th. Re-checks -will be made in the next ten days on all of these locations. V.'e are disturbed about your results op. your Samples #639 and #;6ii0. These .. . samples should be veil below 1.0 and according*to our calculations below 50. It is true that at the time the samples were made the system was not - completely enclosed and some outside air was being drawn in. We also believe there was a bag .lOosp in the adjacent dust collector, contandnating this cut- side air. ' W*e are making immediate checks of the far. speeds on the tape looms where you secured your Bar pie #`6i[l. The dust counts on looms equipped with this type of- exhaust have in the past shewn, the best results. In case of your Sample #65J, we :ently gone to dry warp and fill on these looms v:hich were formerly all vet. Wrs are taking immediate steps to provide exhaust ventilation or. these two looms. In case of yuur Sample #633 around Cards #16, #!?, #iS, and #19 where we normally have quite satisfactory counts, vs believe that this was the period at which the floor had been tern up and the area must have been contaminated by tills work. . ` . I trust that if cither you or Kr. Lunsden are in the Charlotte area that you will not neglect dropping by' to see us. V.'e are going to do some additional work in the blending and on the: conveyor line and then concentrate ili tensively ir the Card Room. Our humidity' system in the Spinning, Twisting, and Winding me in Cloth. Weaving should be in operation in the next thirty' days, control 1:: r.~ the relative h.umidity in these areas to 655 and substantially' reducing the dual counts. A new compressor for this sy'stem is being installed at the nresent time. Tanks are due to arrive next- week. \
