7.0 WORK ZONES AND SECURITY MEASURES <br /> A. General <br /> A site must be controlled to reduce the possibility of exposure to any contaminants present <br /> and their transport by personnel or equipment from the site. <br /> The possibility of exposure or translocation of contaminants can be reduced or eliminated in a <br /> number of ways, including: <br /> • Setting up security or physical barriers to exclude unnecessary personnel <br /> from the general area. <br /> • Minimizing the number of personnel and equipment on-site consistent with <br /> effective operations. <br /> • Establishing work zones within the site. <br /> • Conducting operations in a manner to reduce the exposure of personnel and <br /> equipment. <br /> • Minimizing the airborne dispersion of contaminants. <br /> • Implementing the appropriate personnel and equipment decontamination <br /> procedures. <br /> B. Field Operations Work Area <br /> Work areas (zones) will be established based on anticipated contamination. Within these <br /> zones prescribed operations will occur utilizing appropriate personal protective equipment. <br /> The planned zones are: <br /> 1. Exclusion Area (contaminated). The actual areas where work is being performed <br /> are considered to be the exclusion areas. Access to these areas will be strictly <br /> limited to the personnel needed to conduct the work being performed. <br /> 2. Contamination Reduction Area. An area near to each active work zone will be <br /> designated as the contamination reduction area. Disposable protective gear will <br /> be removed and placed in garbage bags prior to leaving the reduction zone. <br /> Heavy equipment and non-disposable gear will be cleaned at a decontamination <br /> area within this zone. <br /> 3100971B/SSP2.DOC 8 April 12. 1996 <br />
