6.3 Monitoring Field personnel will perforin air monitoring twice daily with a direct reading organic vapor analyzer(OVA, OVM or PID) in the breathing zone at each work location. All readings shall be recorded in field logs. All direct reading instruments shall be calibrated according to the manufacturer's specifications. [Unknown unexpected vapors while drilling the following: If OVA readings for a particular work area consistently exceed 5 parts per million (ppm) above background, then sampling will cease and personnel will withdraw from the work area. If concentrations persist above 5 ppm, then Level C protection will be required if work is to continue. If OVA readings exceed 10 ppm in the breathing zone while workers are in Level C protection, then work will cease and the source of the emission will be identified and controlled before work continues.] PCE may be present in soil gas. Base appropriate action on TI-Vs or PELs listed in Table 3. Field personnel will initially monitor noise levels associated with equipment and machinery with a direct reading portable noise level monitor unless based on experience, it is known that hearing protection is not necessary. Readings will be taken within the normal worker hearing zone. If maximum noise levels exceed 85 decibels at any time during site operations, hearing protection will be worn. 6.4 Site Control Personnel and vehicle entry and exit will be restricted. There will be only one entry and one main exit. Alternate exits will be used only in the event of an emergency. These exits will be clearly marked. All personnel entering or exiting the site will be required to sign a daily log. Work zones will not be established for Level D activities. Individuals not directly involved in ongoing work will be requested to stay at least 50 feet away from Level D activities. 6.5 Decontamination For activities requiring Level D protection and modified Level C protection without established work zones, it is unlikely that major decontamination will be necessary. At the conclusion of each day, disposable gloves and coveralls will be removed and disposed of in onsite containers. If full Level C protection is required, minimum decontamination procedures associated with Level C protection will be followed and established within the decontamination Reduction Zone. These procedures are presented in Table 4. 6.6 Training K/J personnel participating in field activities will have completed the Hazardous Waste Operations and Emergency Response 40-hour health and safety training course (29 CFR 1910.120) or have equivalent training. Training requirements are discussed in K/J's Corporate Health and Safety Program. Prior to each day of work, a meeting will be held at the site to familiarize personnel with health and safety issues, protective equipment, emergency information and supplies, and to discuss special topics. 3r7196 3:09 PM 7 952704.01 9:yobs%52704.01\h&splan.doc
