Employee performed routine duties of reactor operator in the new vinyl unit. No specific cause has been identified. Employee performed routine work of reactor operator. No specific cause has been found. Employee overexposed while changing out a Corken com pressor. ABDOO136634 Routine Chemical Dosimetry Summary Page 2 OVEREXPOSURES - Continued Job Class General Mechanic General Mechanic Exposure 1.5** ppm, VCM 1.7** ppm, VCM Source Employee overexposed while tightening a leaking con denser lid on D-600 reactor. Employee overexposed while repairing the dryer line #2 centrifuge while pond resin was being reclaimed on dryer Line I. General Mechanic Line Compounder 14.8** ppm. VCM 87.6* micrograms Lead/m^ Employee overexposed while changing 742 reactor slow vent line. Employee overexposed while charging blenders on Com pound Line I. * Respiratory protection was worn. ** Respiratory protection was not worn. VCM Area Sampling Three VCM area samples were taken on the roof of the V-ll dryer building during roof repair on 3/16/84. The samples were taken using REAL minimonitors. Wind velocity ranged from 0 to 5 miles per hour, direction being from northwest to southeast: Sample Location On safety railing east of 655 blend tank Sample Time (Hrs,-Min.) 7-ib Result ppip, VCM 0.4 Comments Coarse 5385 resin in 655. On Safety railing east of and between 653 and 651 blend tanks 7-8 2.1 5305 resin in 651 and 653 On safety railing north of 650 blend tank 7-6 0.7 5305 resin in 650 Area Ventilation Checks The second quarter check of lab and compound ventilation hood velocities and flowrates was completed. No serious deficiencies were discovered. ABDOO136635 Routine Chemical Dosimetry Summary * Page 3 Noise Final arrangements for a plant noise survey to be conducted by the Medical Department on April 10-12, 1984 were made. Total Particulates Analysis A five-place analytical balance, suitable for performing total particulates analyses, was purchased and received by the laboratory. Plans are to do all such analysis at Aberdeen beginning in April, 1984. Equipment Calibration The second quarter calibration of the precision rotameter used to measure Bendix BDX 44 air pump flowrates was completed using a large ''bubble tube" as a primary standard. No significant drift was seen. Program Plans Both the Respirator Program and the Work Environment Hazard Control Plan were updated and approved. rah / C" c ABDOO136636 ABERDEEN CHEMICAL PLANT CHEMICAL DOSIMETRY TRENDS - 1 1.1 i i 1 11S s I i i9 82-- >x</$ozo Se .nJ *5s -- a J`i?
