I. VINYL CHLORIDE (OSHA PEL 1 PPM, 8-HR TWA)
During 1994 there were 82 monitorings completed for vinyl chloride
exposure (38 poly/44 dryer).
Of the total monitorings, four (4)
exceeded 1 ppm and 55 (67%) were below 0.5 ppm. No Exposures of greater
than 1 ppm without a respirator occurred in 1994. These.exposures are
summarized below.
