Equipment Calibration and Maintenance <br /> Table 7-1c lists the specific monitoring instruments and the calibration procedures used <br /> on this facility. Instruments are calibrated and maintained according to the <br /> manufacturers' recommendations. Copies of the manufacturers' recommendations and <br /> instrument calibration and maintenance records are located :J 0-6M c e" <br /> ........................................................ <br /> K ........... <br /> (M M A <br /> EA[ <br /> Ta NO T4 40 <br /> 0",it 1 Z <br /> 1 <br /> Instrument Serial Hazard(s) Field Calibration Field Calibration Manufacturer Re-calibration <br /> Number Measured Method Frequency Date <br /> (see Pick Lists at <br /> end of chapter) <br /> Methane Factory Calibrated N/A <br /> Ionizing Factory Calibrate <br /> Radiation <br /> Documentation and Employee Examination <br /> Direct-reading monitoring data will be documented daily, by qualified individuals <br /> (Section 7.0), in the Wastewater Treatment Plant Office. Air sample collection <br /> procedures and analytical results will be documented by qualified individuals during <br /> field investigation. Procedures for documenting both direct-reading monitoring data and <br /> air sampling events are included in Chapter 12, Standard Operating Practices. <br /> Workers may review general air and surface monitoring results and may obtain copies <br /> of their personal monitoring results. (Patrick Riggs, Public Works Superintendent) <br /> provides and interprets this information routinely during pre-entry briefings. Employees <br /> who participated in an air sampling event receive written notification of their respective <br /> personal exposures within (1) days of receipt of results. <br /> 7.2 Surface Monitoring <br /> For this facility decontamination project, surface samples are collected in all work <br /> zones. Surface samples in the EZ provide exposure information. Surface samples in <br /> the CRZ and SZ are used to evaluate the effectiveness of decontamination methods <br /> and exposure controls, including hygiene practices, and to ensure that zone boundaries <br /> accurately reflect the presence or absence of contamination. Surface sample locations, <br /> methods, and permissible contamination limits are listed in Table 7-2. <br /> Surface concentrations in excess of the established limits may results in adjustments of <br /> PPE, decontamination procedures, and controls, and corresponding information in <br /> those chapters of the HASP. Activities will cease in the event any hazardous <br /> substances are detected during soil excavation activities. <br /> Chapter 7 - 6 <br />
