Ira', {r- . sos� ,y_,^2. d�i�Y <br /> �T u � <br /> r <br /> i <br /> A chain-of-custody card (Figure 3) will be used to record <br /> possession of the sample from time of collection to its arrival at <br /> the laboratory. The sample control officer at the laboratory will <br /> verify sample integrity and confirm that it was collected in the <br /> proper container, preserved correctly, and that there is an adequate <br /> volume for analysis. If these conditions are met, the sample will be <br /> assigned a unique log number for identification throughout analysis <br /> and report-ing. The log number will be recorded on the chain-of-- <br /> custody card and in the legally required log book Eureka maintains at .i <br /> the laboratory. The sample description, date received, client' s s <br /> name, and any other relevant information will also be recorded. . <br /> •.a <br /> . - borator-y_ Analytical Quality Assurance <br /> in addition. to routine °`calibration �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 /> 'X precision and accuracy. Accuracy is also verified through the <br /> AK following <br /> N y�Y a <br /> �t 1. Certification by California Department of Health Services. ° <br /> 2. Participation in interlaboratory or round-robin programs. <br /> 3. "Blind" samples are submitted by the laboratory's quality <br /> assurance officer on a weekly basis. 'These are prepared from }F. <br /> National Bureau of Standards or U.S. Environmental Protection ' <br /> Agency reference standards. <br /> Safety Pro ram <br /> It is iraportant thatthe on-site safety program be designed to } <br /> Protect the worker from direct skin contact, inhalation, or ingestion <br /> < s of .' potentially hazardous materials that may 'be encountered at the <br /> t .site. , It should also familiarize the worker with appropriate first <br /> aid procedures in the event of a harmful exposure. In order to do 'rt <br /> this,; the potentially hazardous properties of the materials and their ` <br /> ` toxic effects must be understood. Brown and Caldwell has reviewed <br /> the results of prior chemical analyses performed on samples obtained <br /> from similar sites.
