HEAT STRESS <br /> Heat stress is a concern when field activities are performed during hot weather. <br /> Exposure to temperatures greater than 70 degrees Fahrenheit while wearing protective <br /> clothing and respirators can intensify heat stress. Heat stress can be prevented by <br /> adequate intake of water, worker self monitoring of heart rate (not to exceed 130 <br /> bpm), and scheduled hourly rest periods. If any worker at any time show signs and <br /> symptoms of heat exhaustion (profuse sweating, dilated pupils, weak and rapid pulse, <br /> ' shallow and rapid breathing,abdominal cramps, nausea, difficulty in walking, cool and <br /> sweaty skin) he or she will immediately be removed from the primary area and allowed <br /> to rest in a cooler environment and slowly drink cool water. If symptoms persist after <br /> one hour, medical attention will be sought. <br /> HEAT STROKE <br /> If a worker demonstrates symptoms of heat stroke (hot, dry reddish skin, body <br /> temperature above 105°F, no sweating, deep rapid breathing which progresses to <br /> shallow weak breathing, confusion, dizziness, nausea, vomiting, dry mouth, muscular <br /> twitching, collapse or convulsions), the worker would be moved to a cooler <br /> environment and would be quickly cooled by any necessary means. The victim should <br /> not drink water and would be transported to a medical facility as quickly as possible. <br /> WORK ZONES AND SECURITY MEASURES <br /> The work area is accessible to the public if not kept in check. It will be the responsibility of <br /> the on-site engineer and the drill team to keep public access to a minimum and to discourage <br /> curious passersby. Plastic flagging and traffic cones will help keep unauthorized personnel <br /> from entering work zones. <br /> DECONTAMINATION <br /> Gross contamination will be removed from the equipment and/or protective garments prior to <br /> leaving the site. Cleaning materials would include tri-sodium phosphate (TSP) or Alconox <br /> cleanser and pressurized hot water (steam cleaner). Rinseate will be collected, containerized, <br /> labeled, and left on-site pending chemical testing. Augers, samplers, and well development <br /> and sampling equipment will be decontaminated (cleaned) between borings, followed by <br /> thorough clean water rinsing. Rinseates will be contained. <br /> STORAGE AND DISPOSAL OF SOIL AND FLUIDS <br /> Rinseate will be placed in D.O.T. approved sealed, labeled containers pending chemical <br /> testing. Bore hole cuttings, if any, also will be placed in sealed drums. After an evaluation <br /> of chemical test data,appropriate treatment and/or disposal alternatives will be discussed with <br /> both the client and San Joaquin County personnel. <br /> ■ Geotechnical <br /> T <br /> d <br /> C <br /> lV <br /> 0: <br />
