The drilling company will steam-clean the drilling equipment (augers, <br /> split-spoons, and other equipment) in the decontamination area before drilling each <br /> borehole. <br /> Under Clayton's supervision, the drilling company will decontaminate the split-spoons <br /> before extracting a soil sample from a borehole to minimize the possibility of cross- <br /> contamination between samples. Clayton's geologist will decontaminate other <br /> sampling equipment such a bailers, hand augers, and trowels. During soil and <br /> groundwater sampling, decontamination of sampling equipment (bailers, split-spoons, <br /> hand augers, and trowels) will be conducted in the following order: <br /> (1) Washing and scrubbing with non-phosphate detergent <br /> (2) Rinsing with water <br /> (3) Second rinsing with deionized water <br /> (4) Air drying <br /> 7.4 ELECTRICAL HAZARDS <br /> Overhead power lines, underground power cables, and electrical equipment may pose <br /> shock, electrocution, or fire if contacted or severed during site activities. <br /> Underground utilities will be marked prior to drilling. <br /> Operations adjacent to overhead lines are prohibited unless one of the following <br /> conditions is satisfied: <br /> * Lockoutltagout procedure.
