These zones may be established using cones, barricades, tape, fencing, or other appropriate means. 6.3.1 Exclusion Zone ' The Exclusion Zone is considered to have the highest potential for the presence of ' chemicals of concern. Within this area, the prescribed protection must be worn by personnel in the field, as determined by site conditions and air monitoring data. An entry checkpoint will be established at the periphery of the Exclusion Zone to control ' flow of personnel and equipment between contiguous zones and ensure that the procedures established to enter and exit each zone are followed. ' The Exclusion Zone boundary will be conservatively established in the field by the SSO, or designated representatives, at the time the particular field activity is performed. Subsequent to initial operations, the boundary may be readjusted based on ' observations and/or measurements made in the field. The boundary will be physically secured and posted. 6.3.2 Contamination Reduction Zone The Contamination Reduction Zone will be established between the Exclusion and ' Support Zones. The purpose of this zone is to provide an area to prevent or reduce the transfer of chemicals that may have been picked up by personnel or equipment returning from the Exclusion Zone. All decontamination activities will occur in this area. The boundary between the Support Zone and the Contamination Reduction Zone is the contamination control line. This boundary separates the potentially contaminated area from the clean area of the Support Zone. Entry into the Contamination Reduction ' Zone from the clean area of the Support Zone will be through an access control point. Personnel entering at this station will wear the prescribed PPE for work in the Contamination Reduction Zone. Exiting the Contamination Reduction Zone to the clean area of the Support Zone requires the removal of any suspected or known contaminated PPE and compliance with the established decontamination procedures. 6.3.3 Support Zone The Support Zone is the outermost of the three concentric areas and is considered ' decontaminated, or the "clean area."
