hazardous material sills. Sampling and decontamination media such as hexane, acetone <br /> and nitric acid will be handled in small containers. <br /> Plastic sheeting surrounding boreholes shall be sized to contain the volume of spoil/water <br /> anticipated to be unearthed. Where significant quantities of potentially contaminated water <br /> will be handled, the sheeting will be bermed to prevent the flow of liquids to surrounding <br /> areas. <br /> A supply of sorbents will be kept on-site sufficient to contain the contents of the largest <br /> single portable container of hazardous material (hexane, gasoline, acetone, etc.) The PPE <br /> present for field work is suitable for clean-up of spills of this nature. <br /> 12.0 WORKER DECONTAMINATION <br /> Decontamination is required each time persons leave a work zone and there is reason to <br /> suspect soil contamination.
