Instrument Technician Color Weigh Compounder I 1.8 ppm, VCM Employee overexposed calibrating the old fresh VCM receiver indicator. while unit level 169.6 Micrograms Lead/M3 Employee overexposed while weighing up small quantities of Cyastab 988 and Tribase EXL for Compound Line V in the Color Weigh Room. At writing, the source of the employee's recent overexpo sures has been investigated and related to work practice changes caused by Line V startup. Corrective measures are being taken. * Respiratory protection was worn. ** Respiratory protection was not worn. II. HAZARD COMMUNICATION PROGRAM - A Hazard Communication Program makeup class was held for six people. - The Hazardous Material Reference Books were improved by adding index tabs and hi-lighting the product names on all MSDSs. ABDOO136547 Industrial Hygiene Monthly Report Page 2 III. LAB VENTILATION Lab ventilation hood airflows were checked. found. No abnormalities were IV. SHORT-TERM VCM EXPOSURES Two short-term VCM exposure measurements were made during the blanking of the 745 reactor condenser. The measurements were made using REAL "Minimonitors" worn by two mechanics as they performed the work. Conclusions about the need for respirator protection during this job are being deferred until additional samples have been taken. Mechanic Sample Time (Min.)
