Health and Safety Plan <br /> 1319 & 1327 South Madison Street, Stockton, CA <br /> 432770 <br /> 6.0 AIR MONITORING PROCEDURES <br /> Air monitoring for the presence of volatile organic compounds (VOCs) and will be conducted while <br /> all field work is being undertaken. Air monitoring may necessitate using one or more monitoring <br /> devices as listed in Table 8, particularly if gases, vapors, explosion hazards and/or oxygen <br /> deficient atmospheres can occur and/or are expected. If a monitoring device will be utilized, the <br /> corresponding device letter will be placed in the column labeled "Required Monitoring <br /> Instrument"as noted in Table 9. <br /> Table 8: Monitoring Devices Available <br /> A PID 10.6 eV H Summa Canister <br /> B PID 11.7 eV I Heat Stress Monitor <br /> C FID ) Air Sampling: mini-RAM dr-1000 <br /> D OVA K Air Sampling: <br /> E CGI/LEL L Radiation Detector <br /> F Colorimetric Indicator Tubes M Gas Multimeter <br /> G Dust Monitoring N Other Device: <br /> Table 9 lists the applicable Action Level in the appropriate box using 50% of the most restrictive <br /> (lowest) PEL or TLV as the Trigger as presented in Appendix A or other recognized source. CVOCs <br /> and particulates are the potential airborne hazards anticipated during the planned Site work. <br /> Table 9: Required Monitoring Instrument <br /> Required Trigger Insert Monitoring <br /> Monitoring Constituent Task(s) (Action Level) Instrument Letter' <br /> identified in Table 8 <br /> If monitoring is Oxygen <br /> necessary to Carbon <br /> identify that a risk Monoxide <br /> is at or above 1-12S <br /> acceptable limits C2S <br /> and/or is used in CH4 <br /> controlling a risk VOCs: Total 1,2 0.5 ppm A <br /> on site, document sustained <br /> the task and the Semi - VOCs: <br /> maximum <br /> allowable Metals <br /> exposure or Dusts <br /> trigger, and the Others: <br /> monitoring Others: <br /> instrument <br /> required to be <br /> used. <br /> Page 7 <br />
