Kennedy/Jenks Consultants 5.1.3 Heat Stress Adverse climate conditions, primarily heat, are important considerations in planning and conducting site operations. Maximum daytime temperature in the summertime may exceed 105 degrees F at the site and heat stress is an associated concern. Provisions of the K/J Heat Illness Prevention Program (Attachment G)will be applied to all projects when K/J employees are subjected to sustained temperatures of 85 degrees Fahrenheit or greater. Preventative measures include the followirig: • Water and/or commercial electrolyte solutions will be available and drinking of these fluids will be encouraged. When temperatures exceed 85 degrees Fahrenheit, sufficient water will be provided to accommodate each employee with one quart of water per hour. The water will be kept cool by means of a portable cooler with ice or similar means. • Suitable acclimation periods will be provided for workers to gradually establish their resistance to heat stress. Personnel exhibiting symptoms of heat stress (nausea, cramps, dizziness, clammy skin)will be removed from the work area, cooled, provided with water, and the personnel will be observed. Personnel exhibiting symptoms of heat stroke (hot dry skin, mental confusion, unconsciousness)will be immediately cooled and taken to the hospital. 5.2 Potential Chemical Hazards TPHg, TPHd, lead, and VOCs (low levels) have been detected in soil samples collected at the site. Field personnel could potentially be exposed to organic molecules and lead at the site by direct contact with soil or groundwater, through inhalation of dusts containing organic chemicals, or through inhalation of organic chemical vapors. Field personnel will minimize potential chemical hazards by(1) avoiding direct contact with groundwater and soil, (2) performing air monitoring to determine necessary level of personal protective equipment and (3) avoiding generation of dust. Ingestion of particulate matter containing chemicals is another general exposure route. However, for the site personnel, the potential for this type of exposure is minimal. Safe work practices, including restriction of eating, drinking, or smoking to certain times and places will be enforced at the work site. 5.2.1 Soil Samples TPHg, TPHd, lead, and VOCs (low levels) have been detected in subsurface soil samples collected at the site. The highest reported concentrations are listed in Table 2. Available Threshold Limit Values (TLV) or Permissible Exposure Limits (PEL) published for the chemicals detected in soil are listed in Table 3.
