HEALTH AND SAFETY PROCEDURES FOR SAMPLING, THE INSTALLATION <br /> OF SOIL BORINGS, VAPOR EXTRACTION AND GROUNDWATER <br /> MONITORING WELLS, AND EX-SITU BIOREMEDIATON OF SOIL <br /> The following health and safety procedures have been <br /> developed for personnel participating in site investi- <br /> gations that may involve exposure to fuel hydrocarbon <br /> contaminated soil and/or groundwater. While the referenced <br /> protocol is considered generally appropriate, modifications <br /> may be made by qualified service providers and/or <br /> regulatory agency representatives in response to site <br /> specific conditions . <br /> PRI14ARY HEALTH AND SAFETY STAFF <br /> John Rapp, Registered Environmental Health Specialist <br /> Day Telephone: (209) 538-3768 <br /> Ater Hours : (209) 551-3591 <br /> Ozdemir Beyce, Ph.D. <br /> Day Telephone: (209) 538-3768 <br /> After Hours : ( 415) 325-0311 <br /> Richard Jacobs, Ph.D. <br /> Day Telephone: ( 209) 538 -3768 <br /> Ater Hours : ( 209) 523.7210 <br /> PUBLIC HEALTH/ENVIRONMENTAL HAZARD ASSESSMENT <br /> Hazards associated with the performance of tasks related to <br /> the above referenced assessment and remedial activities <br /> are: 1) Direct exposure to hydrocarbon contaminated soil , <br /> 2) The potential for ignition of flammable-explosive <br /> vapors , and 3) Physical hazards associated with working <br /> near heavy equipment . <br /> HAZARDS OF CHEMICAL EXPOSURE <br /> A portion of the soil in the area of investigation may be <br /> contaminated with gasoline and/or diesel fuel . The most <br /> toxic constituents present in these compounds are believed <br /> to be their aromatic constituents- benzene, toluene, <br /> ethylbenzene, and xylenes (BTEX) ; with benzene the most <br /> toxic of these having been identified as a carcinogen that <br /> forms as much as 3 . 5% of gasoline by weight . <br /> Due to the volatile nature of aromatic compounds, the most <br /> significant route of potential exposure would likely be via <br />
