Good <br />contamination prevention should minimize worker exposure and help ensure valid sample results <br />by precluding cross -contamination. Procedures for contamination avoidance include: <br />Personnel <br />• Do not walk through areas of obvious or known contamination; <br />• Do not handle or touch contaminated materials directly; <br />• Make sure all personal protective equipment (PPE) does not have any cuts or tears prior to <br />donning; <br />• Fasten all closures on suits, covering them with tape, if necessary; <br />• Take particular care to protect any skin injuries; <br />• Stay upwind of airborne contaminants; and <br />• Do not carry cigarettes, gum, etc. into contaminated areas. <br />Sampling/Monitoring <br />• When required by the SHSM, cover instruments with clear plastic, leaving an opening for <br />sampling and exhaust ports; and <br />• Bag sample containers prior to the placement of sample material. <br />Heavy Equipment <br />• Care should be taken to limit the amount of contamination that comes in contact with heavy <br />equipment; <br />• If contaminated tools are to be placed on non -contaminated equipment for transport to the <br />decontamination pad, plastic should be used to keep the equipment clean; and <br />• Excavated soils should be contained and kept out of the way of workers. <br />11.2 Decontamination <br />At the conclusion of Site activities each day, or when leaving the work zone, personnel and <br />equipment shall be thoroughly decontaminated. <br />ROUX ASSOCIATES HASP. 4/93 3425 Tracy Boulevard <br />Tracy, California <br />
