.A; <br /> 6 <br /> A chai n-of-custody Car(J (rigure 3) will be use(! to record <br /> possession of the sample from time of collection to its arrival at <br /> tile laboratory. The sample control officer at the laboratory will <br /> verify sample integrity and confirm that it was collected in the <br /> proper contain,2r, preserved correctly, and that there is an adequate <br /> ;ei volume for analysis. ILE the5e conditions are met, the sample will be <br /> assigned a unique log number ror identification throughout analysis <br /> and reporting. The log number will be recorded on the chain-of- <br /> log book Eureka maintains at <br /> custody card and in the legallY reqUired <br /> the laboratory. The sample description, date received, client' s <br /> name, and any other relevant information will also be recorded. <br /> L a bo,:a!��r Analytical QualitV Assurance <br /> In ad dition to rou*tine I c'.ali b.ration of the instruments with <br /> standards and blanks, the analyst is required to run duplicates and <br /> spikes on 10 percent of the analyses to ensure an added measure of <br /> the <br /> precision and accuracy. Accuracy is also verified through <br /> following: <br /> 1. Certification by California Department of Health Services. <br /> 2. Participation in interlaboratory or round-robin programs. <br /> 3. "B3 'nd" samples are submitted by the laboratory's quality <br /> ficer on a weekly basis. These are prepared from <br /> asburance of <br /> National Bureau of Standards or U.S. Environmental Protection <br /> Agency reference standards. <br /> Safety Proqram <br /> it is important that the on-site safaty program be designed to <br /> protect the worker from direct skin contact, inhalation, or ingestion .. <br /> that may be encountered at the <br /> hazardous materials <br /> of potentially <br /> also familiarize the worker with appropriate first <br /> site. It should <br /> aid procedures in the event of a harmful exposure. In order to do <br /> this, the poCentially hazardous properties of the materials and their <br /> toxic effects muEt be understood. Brown and Caldwell has reviewed <br /> results of prior chemical analyses performed on samples obtained <br /> the <br /> sed to develop the <br /> from s;imilar sites. This information was u <br /> following site safety plan for this work. <br /> personnel Protection <br /> The personnel' protection plan for this project is desi9ned to <br /> prevent sampling . personnel from exposure to petroleum hydrocarbons <br /> which illight be CnCOUntered on site.
