16 <br /> Calculate the adjusted temperature: <br /> T (adjusted) = T (actual + (13 x fraction sunshine) <br /> Measure the air temperature with standard thermometer, shielded from direct <br /> sunlight. Estimate fraction of sunshine by judging what percent the sun is out: 100% <br /> sunshine = no cloud cover 1.0; 50% sunshine = 50% cloud cover= 0.5; 0% sunshine <br /> = full cloud cover= 0.0. <br /> Water and/or commercial electrolyte solutions will be available and drinking of these <br /> fluids will be encouraged. <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 /> 4.2 Potential Chemical Hazards <br /> VOCs and other organic and inorganic chemicals have been detected in groundwater and soil <br /> samples collected at the site and adjacent sites. Field personnel could potentially be exposed to <br /> VOCs and other chemicals at the site by direct contact with soil or groundwater, through <br /> inhalation of dusts containing organic or inorganic chemicals, or through inhalation of organic <br /> chemical vapors. Field personnel will minimize potential chemical hazards by (1) avoiding direct <br /> contact with groundwater and soil, (2) performing air monitoring to determine necessary level of <br /> personal protective equipment and (3) avoiding generation of dust. Ingestion of particulate <br /> matter containing chemicals is another general exposure route. However, for the site personnel, <br /> the potential for this type of exposure is minimal. Safe work practices, including restriction of <br /> eating, drinking, or smoking to certain times and places will be enforced at the worksite. <br /> Soil Samples. PCE has been detected in subsurface soil samples at the site. The maximum <br /> reported level detected is 430 micrograms per kilogram (Ng/Kg). <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 3. <br /> 5.0 COMMUNITY HAZARD ANALYSIS <br /> Generally, insignificant particulate and vapor emissions are generated during routine soil and <br /> groundwater sampling activities. Onsite worker exposure to chemicals at concentrations of <br /> concern is not expected. Potential exposures to the surrounding community will likely be much <br /> less than potential onsite worker exposure, and is therefore also not expected to be of concern. <br /> 3!7196 3:09 PM 5 952704.01 <br /> g:yobs\952704.01\hUplan.doc <br />
