Phase II Sampling and Analysis Plan SOP-5—Equipment Decontamination <br /> Port of Stockton-Rail and Bridge,Stockton,CA FN <br /> STANDARD OPERATING PROCEDURE 5— EQUIPMENT DECONTAMINATION <br /> 1 Purpose and Summary <br /> This Standard Operation Procedure (SOP) provides guidance for proper decontamination of <br /> equipment used in sampling and collection of equipment rinsates to evaluate effectiveness of <br /> decontamination procedures. <br /> 2 Health and Safety <br /> Each individual is required to have read and understood the Site-specific Health and Safety Plan <br /> (HASP)for the project and signed the acknowledgement sheet confirming their review. <br /> Health and safety concerns for equipment decontamination include exposure to contaminants from <br /> sampling equipment. Nitrile gloves and safety glasses should be used during decontamination. <br /> 3 Personnel Qualifications and Responsibilities <br /> Sampling equipment decontamination and rinsate sample collection will be directed by the Field <br /> Team Leader (FTL), an environmental professional (engineer, geologist or scientist)with experience <br /> in equipment decontamination and sampling activities. The field staff, environmental professionals or <br /> technicians, are responsible for following these procedures and seeking direction from the FTL when <br /> questions or problems arise. <br /> 4 Equipment and Supplies <br /> The required equipment and supplies will consist of Alconox soap, distilled water tap water, paper <br /> towels, and sample containers. <br /> 5 Procedure <br /> Proper equipment decontamination will prevent cross-contamination of samples due to residual <br /> contamination from previous sample locations and spread of contamination via sampling equipment. <br /> Proper decontamination also supports the legal defensibility of data generated during site activities. <br /> Decontamination procedures will be evaluated by the collection of equipment rinsate samples. <br /> These samples consist of reagent water collected from final rinse of sampling equipment after the <br /> decontamination procedure has been performed. The samples are analyzed with the environmental <br /> samples to assess the adequacy of the decontamination performed. <br /> 5-1 <br />
