4 , <br /> 7.0 WORK ZONES AND SECURITY MEASURES <br /> A. General <br /> A site must be controlled to reduce the possibilit3 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 cor taminants can be reduced or eliminated in <br /> a number of ways, including: <br /> o Setting up security or physical barriers to exclude unnecessary personnel <br /> from the general area <br /> o Minimizing the number of personnel and quipment on-site consistent with <br /> effective operations <br /> o Establishing work zones within the site <br /> o Conducting operations in a manner to reduce the exposure of personnel and <br /> equipment <br /> o Minimizing the airborne dispersion of co taminants <br /> o 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 ares where work is being performed <br /> are considered to be the exclusion areas. Access to these areas will be <br /> strictly limited to the personnel needed to conduct the work being <br /> performed. <br /> 2. Contamination Reduction Area. An area near to each active work zone will be <br /> designated as the contamination reductior area. Disposable protective gear <br /> will be removed and placed in garbage b gs prior to leaving the reduction <br /> S <br />
