,aria o- <br /> SHARP Management Manual <br /> +''►• Former Tracy MGP Project Safety Plan(PSP) <br /> Respiratory: None <br /> For VOC monitoring, a PID and benzene Draeger tubes will be used. The PID will be <br /> calibrated daily prior to use with 100 ppmv isobutylene span gas. Draeger tubes will be <br /> used according to instructions provided with the tubes. Both the investigation area and <br /> breathing zones of site personnel will be monitored using a PID. If the PID reading <br /> exceeds 1 ppmv, the breathing zone will be monitored for benzene using benzene <br /> Draeger tubes. All site personnel will remain upwind at all times. During disturbance of <br /> contaminated soils, the breathing zones will be monitored continuously and recorded <br /> every 15 minutes. <br /> All air monitoring results will be recorded on the boring logs for each drilling location. <br /> Any additional health and safety issues and requirements shall be included in the field <br /> notebook. <br /> Sampling Type of Minimum Parameter(s)to Minimum Action Level <br /> Location Equipment Calibration be Measured Sampling <br /> Frequency Frequency <br /> Breathing Photo- I per day Total Volatile Every 15 minutes, Upgrade to <br /> Zone ionization Organic or continuously Level C if>5 <br /> Detector(PID) Hydrocarbons when PID readings ppmv for>30 <br /> exceed 5 ppmv seconds <br /> above background <br /> Perimeter of Photo- 1 per day Total Volatile Every hour and Increase <br /> Work Zone ionization Organic when PID readings frequency <br /> Detector(PID) Hydrocarbons exceed 5 ppmv of vapor <br /> above background suppressant; <br /> in the breathing extend work <br /> zone. zone perimeter <br /> Breathing Draeger tubes Leak check prior Benzene PID readings Upgrade to <br /> Zone to use exceed 1 ppmv Level C if <br /> above background concentration is <br /> for 30 seconds to greater than 0.5 <br /> establish the ppmv benzene <br /> absence of <br /> benzene;if benzene <br /> is detected,every <br /> 15 minutes <br /> Perimeter of Draeger tubes Leak check prior Benzene Every 15 minutes, Increase <br /> Work Zone to use if benzene is frequency <br /> detected on the of vapor <br /> Draeger tube. suppressant; <br /> extend work <br /> zone perimeter. <br /> 25 <br />
