Hard hats will be worn during all drilling <br />' activities. <br /> d. Disposable clothing will be properly disposed of at <br />' the completion of the job. <br /> 2 . Respiratory/Eye Protection <br />' a. During drilling activities, ambient air and soil <br /> vapor shall be continuously monitored by a Draeger <br /> tube sampler and an explosive meter. <br />' b. Site perimeter shall also be monitored on 30 minute <br /> intervals . Monitoring frequency would be increased <br />' by the site manager if conditions approach alarm <br /> level. <br />' SITE PERSONNEL <br /> Breathing zone vapor concentrations at the borehole greater than <br /> the Permissible Exposure Limits (PELs) require site personnel to <br /> use a respirator with organic vapor cartridges and goggles . <br /> Breathing zone vapor concentrations at the borehole that approach <br />' the maximum element capacity of the organic vapor cartridge <br /> requires site manager to monitor site perimeter (concentrating in <br /> the down wind direction) . <br />' Breathing zone vapor concentrations at the borehole that exceed <br /> the maximum element capacity of the organic vapor cartridge <br />' requires site activities to be stopped until concentrations <br /> decrease. Site manager should continuously monitor site <br /> perimeter. <br /> I � <br /> SITE PERIMETER <br /> Breathing zone concentrations at site perimeter less than the <br /> PEL, site manager shall monitor on 30 minute intervals unless <br /> notified by project personnel of elevated readings. <br /> IBreathing zone concentrations at the site perimeter greater than <br /> the PEL, site manager shall continuously monitor conditions on <br />' site boundary concentrating in the down wind direction. <br /> Breathing zone concentrations at site perimeter greater than the <br /> NAlim", <br />' CONDOR <br />
