VINYL CHLORIDE VAPOR IN AIR Dispersion Resin Unit Vinyl Resin Area
SOUTH CHARLESTON PLANT
Dear Nick:
Attached are results of additional air samples that you requested for determir vinyl chloride vapor in air throughout the vinyl resin area.
In the general atmosphere all breathing level samples showed concentrations less than 100 ppm.
Nick, to support the concentrations obtained with the Drager Detector tube, we collected bag samples at a few spot locations. The Gas Chromatographic results were as follows:
