Kennedy/Jenks Consultants <br /> be discontinued until proper equipment is obtained or additional monitoring shows that <br /> Level C protection is no longer required. <br /> If non-routine field activities are initiated, the level of protection will be specified in the <br /> activity-specific health and safety addenda. <br /> 6.2 Work Zones <br /> Work zones including designation of an Exclusion Zone, a contamination Reduction Zone, <br /> and a Support Zone will be established for any field activity which requires Level C protec- <br /> tion or greater. Work zones will be clearly marked in the field. Work zones may vary <br /> depending on the proposed field activity and will be established in the activity-specific <br /> health and safety addenda. <br /> 6.3 Monitoring <br /> Field personnel will perform air monitoring twice daily with a direct reading organic vapor <br /> analyzer (OVA, OVM or HNU) in the breathing zone at each work location. All readings <br /> shall be recorded in field logs. All direct reading instruments shall be calibrated according <br /> to the manufacturer's specifications. Additional monitoring requirements for non-routine <br /> site work will be specified in the activity-specific health and safety addenda. <br /> If air monitoring readings for a particular work area exceed five parts per million (ppm) <br /> above background in two readings made 15 minutes apart, then sampling will cease and <br /> personnel will withdraw from the work area. if concentrations persist above 5 ppm, then <br /> Level C protection will be required if work is to continue. If readings exceed 10 ppm in the <br /> breathing zone while workers are in Level C protection, then work will cease and the <br /> source of the emission will be identified and controlled before work continues. <br /> 6.4 Site Control <br /> Personnel and vehicle entry and exit will be restricted onsite. Offsite work zones will be <br /> secured using traffic controls and yellow caution tape. Work zones will not be established <br /> for Level D activities. individuals not directly involved in ongoing work will be requested to <br /> stay at least 50 feet away from Level D activities. <br /> 6.5 Decontamination <br /> For activities requiring Level D protection and modified Level C protection without estab- <br /> lished work zones, it is unlikely that major decontamination will be necessary. At the con- <br /> clusion of each day, disposable gloves and coveralls will be removed and disposed of in <br /> onsite containers. In addition, work boots will be removed and cleaned in a decontamina- <br /> tion solution, or using a pressurized spray washer, prior to leaving the site, if boot covers <br /> have not been used. <br /> If full Level C protection is required, minimum decontamination procedures associated with <br /> Level C protection will be followed and established within the decontamination Reduction <br /> Zone. These procedures are presented in Table 4. <br /> gNobs%9405491H&Sp1anlp1an 7 940549.00 <br />
