6.0 - SITE SECURITY AND CONTROL 6.1 Work Zones Restricted Site areas will include, but not necessarily be limited to,the following zones: • Exclusion Zone or Hot Zone-any area where contamination is either known or likely to be present in concentrations that could pose a threat to human health and safety or that potential for harm to personnel exists because of the type of work activities being conducted.Appropriate PPE and warning signs should be utilized in this area. • Contamination Reduction Zone-any area where workers conduct personal and equipment decontamination. • Support Zone-areas where access is controlled,but the chance to encounter hazardous materials or conditions are minimal. Access to the work zones will be controlled by work zone delineators(e.g.traffic cones, flags,vehicles, DOT approved devices,temporary or permanent fencing, and/or safety barrier tape). Figure 6-1 is an example of a work zone.Additionally ATC employees should follow the requirements of the Employee Health and Safety Policy Manual,Policy No. 36,Work Zones in Traffic Areas for additional information. In the event on-site personnel must upgrade their personal protective equipment,the work zones may require substantial modification in order to provide for the safety of nearby personnel not associated with this work. Any upgrade level will be communicated by the Site Supervisor to the PM. The PM will then inform the RSC of this occurrence.
