IV. SITE EVALUATION <br /> A. Chemical Hazards <br /> The primary chemical hazard to which field personnel may be potentially exposed <br /> is gasoline hydrocarbon vapors volatilizing from the excavation of the possible <br /> gasoline contaminated soils. No previous petroleum hydrocarbon laboratory <br /> analysis of soils has been completed at this site. <br /> 1. Gasoline / CAS # 8006-61-9 <br /> Properties: see attached. <br /> B. Physical Hazards <br /> No significant physical hazards are anticipated. <br /> 1. Potential exposure to nuisance dust from soil excavation, removal and <br /> moving of U.S.T.'s during construction operations. <br /> 2. Potential particle in eye hazard if wind conditions develop. <br /> 3. Potential exposure to traffic hazards associated with vehicle/equipment and <br /> crane operations. <br /> 4. Potential intermittent exposure to noise at levels above 90 dBA. <br /> 5. Potential physical injury hazard from operation of heavy equipment, i.e. <br /> front-end loaders and excavators. <br /> 6. No heat stress hazard is anticipated because of predicted ambient weather <br /> conditions (with day time temperatures of 70-80°F). <br /> 7. No anticipated high voltage electrical hazards (no overhead or underground <br /> utilities in the construction area). <br /> V. JOB HAZARD SUMMARY <br /> The excavation and possible stockpiling of spoils from gasoline contaminated soil will be <br /> covered with 6- mill poly sheeting. These activities present minimal potential exposure <br /> or hazards for field employees. The work area is isolated with a 6 foot high cyclone fence <br /> 2 <br />
