Site Health and Safety Plan Countryside Market, Stockton, California March 21, 2014 7.0 SITE CONTROL MEASURES 7.1 Designation of Work Zones Specific work zones are identified for projects where contaminated soils are exposed and may release their contaminants to the air, or come in contact with field personnel. To minimize the migration of contaminant from the Site to uncontaminated areas, the following three work zones will be set up: Zone 1 — Exclusion Zone Zone 2 — Contamination Reduction Zone Zone 3 — Support Zone The Exclusion Zone is the area where contamination occurs or could occur. Initially, the Exclusion Zone should extend a distance of 25 feet from the edge of intrusive activity unless conditions at the Site warrant either a larger or smaller distance as determined by the Site Health and Safety Coordinator. All persons entering the Exclusion Zone must wear the applicable level of protection. It is anticipated that work zones will be established at each individual area of intrusive work rather than encompass the entire Site. Between the Exclusion Zone and Support Zone is the Contamination Reduction Zone, which provides a transition between the contaminated and clean areas of the Site. The Contamination Reduction Zone will be located directly outside the Exclusion Zone. All personnel must decontaminate when leaving the Exclusion Zone. A Contamination Reduction Zone (decontamination area) will be established adjacent to each individual area of intrusive work. The Support Zone is the area of the Site where significant exposure to contamination is not expected to occur during non-intrusive activities. The Support Zone is considered to be the "clean area" of the Site. 7.2 Confined Space Entry Confined space entry is not anticipated as part of this scope of work. If needed in the future, confined space entry protocols will be described in an Appendix to this HASP and will require specific health and safety measures. 7.3 Emergency Exit Evacuation routes will be discussed in the tailgate safety meeting and included in the site plan as appropriate (Figure 2). During an emergency, these routes should be followed unless conditions HASP 21MAR2014 7-1 APEX
