General Manager Gentlemen: On February 13, 1969 we conducted a dust study of the various representative operations carried out in the manufacture of brake linings. .* ' Air samples were collected in the breathing zone of the workers for dust content anc compared to the limit of 5 mil lion particles per cucic foot of air. All of our samples collected, except two, '..ere below the maximum allowable concentration. ..here tne employee was dumping the asbestos mix from the can into the press for disk brake pads, the dust count was slightly areve the limit. The other sample where the limit was exceeded, was on the bra.<e lining grinder in bay s-6 wnere the ventilation to the machine was disconnected. During our visit we discussed these two machines and found tr.at cox-rective measures were going to be taken on the press and that tne ventiiaticr. to the brake grinding machine would be reconnected. Until these changes are made, respirators should be worn to protect the workers from over-exposure to asbestos dust. We plan to visit your slant within the near future to examine the control measures rlaced on the new mixers installed to prepare the brake lir.ir.j material. If the controls are satis factory, it snoulc be a vast improvement over the batch type unit now in use. "Equal Hrallh Opportunity for AlT 14.
