The criteria for such protocols are <br /> provided below. <br /> Instrument Breathing Zone Action Taken <br /> (As Applicable) Reading <br /> Photoionization Total <br /> detector(PID) (MiniRae 2000 Ora.Vapors Level D. Work may continue. <br /> or equivalent) Bkgrd-20 ppm <br /> Leave area. Contact Project Manager for <br /> 20-200 ppm direction. If re-entry authorized by Project <br /> Manager,use air-purifying respirator with <br /> organic vapor canisters. <br /> >250 ppm Leave area. Contact Project Manager for <br /> direction. <br /> The NIOSH pocket guide to chemical hazards forms for the Site-specific contaminants are <br /> provided in Appendix D. <br /> 7.2 FREQUENCY OF AIR MONITORING <br /> The breathing zone of field employees on-Site will be monitored every hour (at a minimum) and <br /> recorded in an air monitoring log provided in Appendix E. A qualified individual will calibrate the <br /> PID before and after field activities. Calibration will be documented in the calibration log provided <br /> in Appendix F. <br /> 7.3 RECORDS RETENTION AND DATA REPORTING <br /> The air monitoring log and instrument calibration log are provided in Appendices E and F, <br /> respectively. The air monitoring log must include the following minimum information: <br /> Name of personnel <br /> 21 MIL L EN" KS <br /> P:\707 Cove Contractors\Groundwater\Well Installation Workplans\SHSP\SHSP_FINAL.doc <br />
