In addition, numbers and locations of excursions for the regulated area were taken by scanning the area monitoring GC charts. CONCLUSIONS A. Personnel Monitoring 1. Twenty employees were monitored in December. Range 0.0 to 0.5 ppm VC1 0.51 to 1.0 ppm VCI 1.0- over ppm VCI No, of Employees 20 0 0 2.
