S. lane Industrial Hygiene Survey; Red Oak - December 10-11, 1975 BUBIRKSS C0HF1KNXIAL Dear Mr. Skahill: A routine periodic industrial hygiene survey was conducted at the Red Oak plant on December 10-11, 1975. All plant areas were inspected, and air samples were collected for airborne dusts, fumes and vapors. These air samples were analyzed for total dust, arsenic, manganese, lead, vinyl chloride monomer, perchlorethylene and methyl isobutyl ketone (MIBK). This second set of air samples collected here for arsenic analysis yielded results which were quite comparable to those of the first set. The results of air samples collected for approximately 6J hours each on a Mix Screener and a Cramic Molding Machine Operator showed a time-weighted average exposure of less than 0.001 mg/K3 to arsenic. Urns, each of the 4 shift-length air samples collected in this mixing and forming area during 1975 gave results of less than 0*001 mg/M* as the time-weighted avergge concentration for exposure to airborne arsenic. This is less than 0.2 of the existing 06HA standard for arsenic, and less than 50 oven of the proposed new threshold limit value. The time-weighted average concentrations for the exposure of the Mix Screener and the Cramic Molding Machine Operator to airborne manganese dusts were 0.30 and 0.29 mg/M^, respectively. Thus, the average exposure measured here during 1975 for each of 3 Job classifications (also Mix Operator) was less than 10jt of the threshold limit value for manganese in workroom air. A personal air sample was collected for approximately 6 hours on one of the operators on the finishing line. This gave a time-weighted average concentration for lead of less than 0.004 ag/)P, This calculates to be less than 2% of the existing threshold ltait value for lead in workroom air. This was the only such sample collected here for lead analysis during 1975. ucc 067882 Mr. J. H. Skahill 2- Januaxy 23* 1976 Tha exposure to total dust and fuse continues to be acceptably low at operations in the Red Oak plant. During this visit the time-weighted average exposures to total dust and fune for the Cmamlc Molding Machine Operator, Mix Screener, and finishing Line Operator were 2.09, 1.71, and 0.06 mg/M3, respectively. The air sample collected for approximately 7-hours (12/10/75) on the Xxtrusion Machine Operator contained less than 0.05 parts per million (by volume) of vinyl chloride monoawr, Thus, none of the air samples collected on this operator has ever contained as much as the OSHA action level of 0.5 parts per million (by volwe) of vinyl-chloride monomer as a time-weighted average concentration. During the afternoon of 12/10/75, spot air samples were collected for perchlorethylene in the aisle beside both the Blakeslee and the Phillips Degreasers. No concentration as high as 10 parts per million (by volume) was found. This indicated that the local exhaust ventilation systems of both degreasers were functioning properly. A personal air sample, collected on the Roll-Coat Operator during the day shift on 12/11/7?* gave a time-weighted average concentstion of 90 parts per million (by volume) for methyl isobutyl ketone In workroom air. Spot air samples, collected both forenoon and afternoon on this same day, had indicated 100 ppm (the OSHA TLV) as the concentration at the time of each sample. Additional shift length air samples are needed here to better evaluate the concentrations of both MIBX and toluene to which this operator is exposed. I greatly appreciate the courtesies extended to me during my visit. If I can be of further assistance, please let me know. Very truly yours, S. 0.

Welsh/Dr. K. 8. lane Dear Mr. Alspaugh: On January 7, 1976 air samples were obtained at case molding and 0 ring molding to determine what air-borne concentrations of vinyl chloride might be present from the use of PVC resins in these items. At the case molding unit, the operator wore a personnel sampler during both the morning and afternoon segments of the shift. In neither case were vapors of winyl chloride detected. Operating difficulties were experienced with the 0 ring mold and two samples obtained at this location in the morning indicated 0.18 parts per million of vinyl chloride. The unit did not operate in the afternoon. Pram these results and those taken in May of 1971*, it is Indicated that msployees at these operationssare not being exposed to levels of vinyl chloride requiring further action. In the future, additional samples may be obtained to ascertain that concentrations remain at these levels or lower. If you have any questions, please let me know. Very truly yours, LJl/eg L. J.
