0 0 <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 /> 5.2.3 Cold Exposure <br /> ' Cold injury (e.g., frostbite and hypothermia) and impaired ability to work are dangers <br /> encountered at low temperatures and high wind-chill factors. To guard against these conditions, <br /> ' if cold weather becomes an important consideration at this Site, field personnel should wear <br /> appropriate clothing, have access to readily available warm shelter, take carefully scheduled <br /> work and rest periods, and monitor the physical conditions of other workers. <br /> 5.3 Potential Chemical Hazards <br /> Diesel range organics have been detected in soil and surface water samples collected at the <br /> Site. Field personnel could potentially be exposed to the diesel fuel at the Site by direct contact <br /> with soil or water, through inhalation of dusts containing the organic chemicals, or through <br /> inhalation of organic chemical vapors. Field personnel will minimize potential chemical hazards <br /> ' by(1) avoiding direct contact with soil and water, (2) performing air monitoring to determine <br /> necessary level of personal protective equipment, and (3) avoiding generation of dust. <br /> Ingestion of particulate matter containing chemicals is another general exposure route. <br /> ' However, for the Site personnel, the potential for this type of exposure is minimal. Safe work <br /> practices, including restriction of eating, drinking, or smoking to certain times and places will be <br /> enforced at the work Site. <br /> 5.3.1 Soil Samples <br /> ' Diesel range organics have been detected in subsurface soil samples collected at the Site. The <br /> highest reported concentration is listed in Table 1. <br /> Available Threshold Limit Values (TLV) or Permissible Exposure Limits (PEL) has not been <br /> established for the diesel fuel detected in the soil samples, Table 2. <br /> Health and Safety Plan Page 7 <br /> Union Pacific Railroad Company, Stockton Railyard Site, Stockton, California <br /> g:\ad6nasstlobs120031032777.16_unionpacific-stocktonyard109-reports19.09 reports2005_hasplhasp.doc <br />
