Kennedy/Jenks Consultants <br /> • Water and/or commercial electrolyte solutions will be available and drinking of these <br /> fluids will be encouraged. The water will be kept reasonably cool. <br /> • Suitable acclimation periods will be provided for workers to gradually establish their <br /> resistance to heat stress. <br /> Personnel exhibiting symptoms of heat stress (nausea, cramps, dizziness, clammy skin)will be <br /> removed from the work area, cooled, fluids will be administered, and the personnel will be <br /> observed. Personnel exhibiting symptoms of heat stroke (hot dry skin, mental confusion, <br /> unconsciousness)will be immediately cooled and taken to the hospital. <br /> 5.5 Potential Chemical Hazards <br /> Lead has been detected in soil samples collected at the site. Field personnel could potentially <br /> be exposed to petroleum hydrocarbon compounds at the site by direct contact with soil or <br /> groundwater, through inhalation of dusts containing organic chemicals, or through inhalation of <br /> organic chemical vapors. Field personnel will minimize potential chemical hazards by <br /> (1) avoiding direct contact with groundwater and soil, (2) performing air monitoring to determine <br /> necessary level of personal protective equipment and (3) avoiding generation of dust. Ingestion <br /> of particulate matter containing chemicals is another general exposure route. However, for the <br /> site personnel, the potential for this type of exposure is minimal. Safe work practices, including <br /> restriction of eating, drinking, or smoking to certain times and places will be enforced at the work <br /> site. <br /> 5.5.1 Groundwater Samples <br /> Chemicals detected in the groundwater from the site and the highest detected concentrations <br /> are listed in Table 2. <br /> 5.5.2 Soil Samples <br /> Lead has been detected in subsurface soil samples collected at the site. The highest reported <br /> concentrations are listed in Table 3. <br /> Available Threshold Limit Values (TLV) or Permissible Exposure Limits (PEL) published for the <br /> chemicals detected in soil and groundwater are listed in Table 4. <br /> Site Health and Safety Plan Page 9 <br /> Former Tracy Railyard, Tracy, California <br /> g:\is-group\adrrnWb10510565777.03_upa%Sreportslwork p1an4i finahappendices\ppc_hasplappc_texl.doc <br />
