Green subject Airborne Asbestos Monitoring at Chicago Joint Cement Plant location location date Chicago Tigard April 29, 1976 Three production workers at the Chicago Plant were monitored for airborne asbestos fibers on April J), 1976. All the time weighted averages continue to be well below the maximum of 5 fibers per milliliter. The overall average of 0.57 is slightly higher than the previous count. The reason for this is explained in the letter from George Fowler which is attached to this report. The fiber counts were done by Dawn Steyaert. GWG/gvp Att. Mr. J. R. Hurd - Portland Mr. T. VJ.

Normal production was observed. A new dry blend mixer man was working that area. He had been on the about three weeks. General plant was clean with good housekeeping observed in most areas. job GFF/gvp / G. F. F. SGP 0021630 AIRBORNE ASBESTOS FIBER SAMPLING Plant Name ^ TX Te.

Production was limited to Ready Mix and Ready Mix Filler. Mike Oravis was a new man doing the dry nlending. It was noted that due to his inexperience, an excess amount of dust was created. Generally, good housekeeping was observed at most working stations. Production for the day was just slightly down from their average production. Please note that on two of the reports, additional pumps were used. This was due to minor malfunctions. Sample #364 is being returned as a blank. / / - GFF/gP G. F. F. CP 09 SGP 0021638 Plant C.
