GeoSyntec Consultants <br /> identified hazards. Hazard analysis involves a complete review of chemical, physical, <br /> and biological hazards. <br /> 5.1 Chemical Hazards ❑ APPLICABLE ® NOT APPLICABLE <br /> A comparison has been made between previous environmental sampling results and <br /> EPA Primary Drinking Water Standards (for liquids) and EPA Soil Screening Levels <br /> (for solids) to select those contaminants that may cause health and safety concerns, <br /> henceforth referred to as Contaminants of Concern. Based on this comparison, only <br /> contaminants that: exceed 5 times these standards have been considered Contaminants of <br /> Concern as indicated in Table 4. Contaminant Fact Sheets for each of the <br /> Contaminants of Concern for this project are provided in Appendix B. <br /> Information from. the Contaminant Fact Sheets (e.g., flash point, water reactive, <br /> etc.) have been utilized in performing the chemical hazard analysis in Table 5 (e.g., fire, <br /> inhalation, reactivity, and skin absorption hazards). If, based on the hazard analysis, <br /> chemical hazards exist, hazard mitigators must be utilized to control these hazards <br /> (Appendix C). In addition, air monitoring equipment (Section 6) and personal <br /> protective equipment (Section 8) must also be utilized to evaluate airborne <br /> concentrations and protect workers. <br /> 5.2 Physical Hazards ® APPLICABLE ❑ NOT APPLICABLE <br /> Physical hazards associated with tasks to be performed (e.g., electrocution due to <br /> drilling, etc.) and site location (e.g., slips, trip, or falls due to rocky terrain, etc.) have <br /> been analyzed in Table 5. If, based on the hazard analysis, physical hazards exist, <br /> hazard mitigators (Appendix C) must be implemented. <br /> 5.3 Biological Hazards ® APPLICABLE ❑ NOT APPLICABLE <br /> If, based on the hazard analysis (Table 5), biological hazards exist associated with <br /> tasks to be performed and site location (e.g., allergic reactions to poisonous plants or <br /> insects indigenous to the area, etc.), hazard mitigators (Appendix C) must be <br /> implemented. <br /> Vernalis_2007_HASP.doc 5 16 July 2005 <br />
