The following potential exposures and hazards have ? <br /> i <br /> U <br /> been identified: <br /> ie f <br /> o Volatilization of gasoline hydrocarbons during all <br /> operations poses a potential hazard, via the inhalation <br /> of vapors. <br /> � o Skin and eye contact with the impacted soil and water ! <br /> may occur during drilling, and soil and groundwater i <br /> sampling, as well as when cleaning sampling equipment. <br /> �j <br /> I <br /> o Atmospheres that contain a level of oxygen greater than <br /> 25% pose ars extreme fire hazard (the ambient oxygen <br /> level is approximately 20.5%) . This is compounded by 1. <br /> t <br /> the fact that the vapors are flammable. <br /> -- o Look for falling objects, slipping, and tripping <br /> hazards (Visqueen sheet used to hold excavated soil can <br /> be slippery) . <br /> i <br /> o Be aware that a heat stress situation may develop when <br /> impermeable protective clothing is worn. <br /> o Limit exposure time to noisy equipment, such as <br /> jackhammers, scrapers, compressors, or vacuum trucks. <br /> The noise level can be .as high as 100 dba at the <br /> source. <br /> 3 <br /> 6 <br /> 4 �. <br />
