Iv. DAMES a RE aCTIVITIES ON SITE <br /> Dames a Moore proposes to install approximately 10 to 12 soil <br /> boring„ to a total of 25 to 30 feet each. Ro inas will be advanced <br /> using a truck-mounted drill rig with hollow-stem augers. Soil samples <br /> will be collected during the boring installation using a Dames & Moore <br /> U-type 504.1 sampler. Several soil samples from each boring will be <br /> selected for chemical analyses for total petroleum hydrocarbons. The <br /> borings will be installed in areas where diesel contamination was pre- <br /> viously detected, <br /> V. HAZARD ANALY&I5 <br /> Based on the site -,ackground and planned activities, the following <br /> types of hazards exist: <br /> Pinch points associated with the drilling equipments <br /> ° overhead;felli,,y uhject_ associated with the drilling equipment= <br /> ° Skin contact with ecntaminated soil or water while sampling; <br /> ° Inhalation of diesel fumes while drilling; and <br /> ° Inhalation and ingestion of soi2 particles contaminated with <br /> di*sel or pentachlorophenol. <br /> rreviouz invesLiydLlcuia have indicated soils are contaminated with <br /> diesel. In addition, it is suspected that pe taohlorophenol may be <br /> present in the soil or ground water on site. Therefore, with regards to <br /> vapor and particulate inhalation and particulate ingestion, protective <br /> mcanures requir-iny Let-plLatory protection and cr anic vapor monitoring <br /> must be instituted. Also, protective measures must be instituted to <br /> prevent and mitigate icjuries resulting from overhead hazards and skin <br /> contact with contaminated soil and water. Specifies regarding necessary <br /> proteCLive measures are- addressed in the next section and in Tables 3 <br /> and 4. In addition, the attached MSDSes and TLbles 1 and 2 contain <br /> health and safety information on diesel and pent tahlorophenol that may <br /> be present in the soil or ground water. <br /> VI. PERSONNEL PROTECTIVE MEASURES AND UIPME <br /> During drilling and sampling activities within 25 feet of the drill <br /> rig personnel shall wear: safety goggles, hard hats, nitrile gloves or <br /> nitrile gloves beneath canvas gloves, tyvek coveralls, safety boots with <br /> rubber boot covers, and half-mask or full-face (if full-face is used, <br /> then no need for safety glasses) MSA respirator with GMC-x cartridges. <br /> -2- <br />
