modifications to the level of protection, additional medical monitoring and training, and <br />implementation of further engineering controls. <br />It should be noted that freshly exposed soil and the lack of ventilation in the excavation <br />might exacerbate <br />the <br />airborne concentrations of <br />organic vapors by allowing vapors to <br />concentrate. The <br />Site <br />Safety and Health Officer <br />will take special care to monitor these <br />conditions. <br />Care will be taken to avoid dusty conditions resulting from work activities. Presence and <br />concentrations of dust, if any, will be monitored in accordance with the Site Health and Safety <br />Plan. Fugitive dust will be monitored by all Geofon personnel, and mitigated by correcting <br />vehicle/machinery operation and/or by wetting exposed surfaces. <br />If required, prior to commencing excavation or removal and loading operations, soils <br />and/or the stockpile surface will be thoroughly wetted with water to prevent potential off-site <br />migration of dust. The process will be repeated as required to prevent the generation of dust. <br />Geofon personnel will carefully apply water used to mitigate dust. Water use will be monitored <br />at all times and at no time will water be allowed to run or pond on-site in excessive quantities <br />that would create hazardous or dangerous conditions for personnel or equipment. Should excess <br />water use be detected, the Geofon Project Manager will be notified immediately and the situation <br />will be immediately corrected. <br />Any offsite release or suspected offsite release of hazardous substances must be <br />immediately reported to the Site Safety and Health Officer. Any suspected exposure to <br />hazardous substances resulting from PPE failure, accident, or other reason must be reported to <br />the Site Safety and Health Officer, in writing, within 24 hours. <br />46 <br />
