BASF Wyandotte Corporation TO R. W. McNab OATE F \-iJf hr^:^ \M;j t CE MEMORANDUM Geismar - February 22, 1972 FROM P. E. Armstrbng SUBJECT Asbestos Dust in Cell Renewal COPIES CWAxce, ifjRonayne, MNDokken, GJMelanson, REFERENCE HWMcNab to JJRonayne & MNDokken 2-1-72 Same Subject ' I either don't understand the results shovn in the referenced memo, or I don't understand the standard. As I see the data, the lab found a total dust count (lead, asbestos, dirt, and others) ranging from 2.3 to 7-9 MPPCF. The lab could find ncs asbestos fibers 5 microns long. Since ve are allowed 5 fibers per ml. of sample, it seems to me we passed the OSHA asbestos in air standards with flying colors. Correct my thinking if it is wrong, please. Warren, what was the TWAE on the dust count? Are there any industrial or legal standards we can use for dust counts in general? PEA/ee P E. Armstrong F 46 8
