W* S. McCormick 0/0020 - Akron 9/5-1 October 8* t$4 Louisville Plant Industrie! Hygiene Survey Louisville Plant Wo hove received end studied your note* together with George Wilson's hygiene survey which ho Issued based on his work at Louisville during tho period September 1-5. As regards tho handling of Iced compounds wo plan to do the followlngi 1* Install exhaust ventilation at tho sklpt hoist on the 4" Ferrol lino. 2. Further Investigate the adequacy oP ventilation at tho Henschel Mixer on tho 4*1 Ferrol line. 3. Review with all personnel handling lead compounds tho necessity for tho maintenance of good work habits, particularly, with regard to minimising dusting while handling theso compounds. 4. Wo plan to partition and to extend the hood at the Building 3 weigh station. 5. We are reemphasising tho necessity for good personal hygiene among personnel handling lead and antimony compounds. Wo are also posting In additional locations. Including tho lunch room, smoking room, shower room and all weigh booths a list of lead handling rules and personal hygiene rules. Vie agree with your recommendation that liver function studies ore not re quired on a regular basis for personnel In our EDC unit* Wo will continue, to make these examinations on a pro-asslgnmont basis to personnel assigned to this unit. Doth you end Mr. Wilson have mode recommendations to us concerning vinylfdone hazards* based on the analysis of th^ various samples obtained by Mr. Wilson during his visit* One recommendation was to prevent spillage of vinylldune chloride during drum handling operations. We will certainly moke ovary effort to minimize such spillage, however. In tho rare Instances where spillage does occur, tho spill will bo promptly and thoroughly washed down and personnel will bo instructed to ovoid Inhalation of fumes. Wo have boon doing some work with our vlnylidono recipes which wo hope will enable us to discontinue tho use of j vfnylldone In drums and to permit us to use all of our vinylldana In bulk from '5 * our tank farm, i NGC39450 To?
