PID w/lamp of 10.2 ev Yes <br /> RISK ASSESSMENT <br /> i ' I' III The primary safety goal during the contamination analysis is to <br /> protect the sampling team and support staff while they acquire <br /> j representativsamples and monitor air quality. If proper LLL <br /> ? values ar, ,aintained, then the risk of explosion and resulting <br /> I fMire will i,e minimal. Due to the unconfined nature of the proj9ct <br /> site, toxic vapors released during the operations will be <br /> sufficiently diluted by ambient air so that the surrounding <br /> community will be exposed to ziegligible risk. In order to assure <br /> '. that vapor dispersal is adequate, a handheld Photo Ionizing <br /> trr( Detector (PID) will be used to monitor vapor concentrations. <br /> ur EXPOSURE MONITORING PYRAN <br /> Environmental exposure will be monitored periodically using a hand <br /> held PID and an LEL/02 meter. Personal exposure monitoring (in <br /> t', addition to the annual check-up) will not be conducted. <br /> +i fl All personnel have been approved for respirator use. <br /> All WEGE personnel have current 40 hour OSHA certification. <br /> WORK ZONES AND SECURITY MEASURES <br /> IT <br /> ISI`. j <br /> The work area will be restricted to WEGE personnel and site/job <br /> i specific sub-contractors near the sampling. Site access will be <br /> .�. restricted as needed by Mr. Bennett during ground water sampling <br /> operations. <br /> i <br /> t=: ; <br /> rr:�rr :•j . <br /> s� DECONTAMIMATION MEASURES <br /> , At the end of each work day, all WEGE personnel will thoroughly <br /> I wash their hands, face, and footwear before leaving the site. In <br /> lj the event that personal protective equipment is necessary, all <br /> disposable items will be deposited into a steel drum container on <br /> site and all reusable items wil be washed with TSP detergent and <br /> rinsed with clean water. Residual liquid will be placed in a = <br /> steel drum container on site. Personnel will not be allowed to <br /> leave the contaminated area without completing the decontamination <br /> process. <br /> F • `GENERAL SAFE WORK PRACTICES <br /> All personnel wil be alert for trucks and other vehicles entering <br /> �, I • and leaving the site. <br /> .• ! <br /> II, All personnel performing sampling will wear disposable gloves. <br /> Anyone entering the site without authorization will be asked to <br /> leave and escorted out of the control area. <br /> J <br /> I:• S ' <br /> 1 <br /> i <br />
