Fifteen employees were monitored in January. Range 0.0 to 0.5 ppm VCI 0.51 to 1.0 ppm VCI 1.0- over ppm VCI No. of Employees 15 0 0 % 100% 0 0 2. All employees tested in January were below the .5 ppm action level. 3. See data attached. B. VCM Area Monitoring 1. The VCM area monitors consist of two Bendix gas chromatographs having ten sample points each throughout the VCI Complex. 2. The chromatograph charts were scanned for excursions of VCI: a. Over 5 ppm extending over a 15 minute period. b. Over 1 ppm extending over an 8 hour period. c.
