Employee overexposed while weighing up Cyastab 523, 564 and 988 in the color weigh room.
Compounder
61.7 M^crograms Lead/M
Employee overexposed while charging Line III blenders with Cyastab 564.
Compounder
36.6 Micrograms Lead/MJ
Employee overexposed while charging Line III blenders with Cyastab 564.
* Respiratory protection was worn.
II. VENTILATION
The quarterly check of the compound ventilation system revealed decreased airflows through the Line III blende'* hoods. The hoods were then cleaned out by operations and re-checked, showing the flows to be back to acceptable levels.
III. RESPIRATORY PROTECTION
The plant's respirator program was revised and submitted for approval.

IV. OSHA HAZARD COMMUNICATION STANDARD
The plant's hazard communication program was revised and distributed to plant department heads for comment.
Copies of Tel-A-Trains "Chemical Safety, Parts 1 and 2," videotapes were ordered for use in hazard communication training.
Ringbinders for the plant's "Hazardous Materials Reference Books" were ordered.
V. SHORT-TERM VCM EXPOSURES
One set of short-term VCM exposure measurements was made during blanking of 744 reactor. The measurements were made, using REAL "Minimonitors" worn by three mechanics while they performed the work. As shown below, Mechanics "A" and "B" confined their work to blanking out the bottom of the reactor, while Mechanic "C" blanked out the condenser. Conclusions concerning the need for respiratory protection during this job are being deferred until additional samples have been taken.
