Project Plan <br />Revision 6 <br />1/8/1988 <br />Page 19 of 37 <br />analytical check-out samples during audits. Any problems detected are <br />immediately reported to the Laboratory Director and a solution determined. <br />Audits will be carried out on a pre -announced date. A final audit report <br />M. is submitted to the Laboratory Director covering both system and <br />performance evaluations. <br />6.2 Workbook Checks <br />workbooks, including standard books and logbooks, are to be checked <br />bi-monthly by the QA/QC officer. The findings are to be recorded on a <br />report to the Laboratory Director, Data Book Check. Among the items to be <br />checked are sample indentification, cross-referencing, completeness of data <br />recording and accuracy of calculations. <br />6.3 Data Retrieval <br />In order to assure that reports and data have been properly stored d <br />can be easily retrieved, retrieval tests are to be made on reports randomly <br />selected from log books. This is to be done 5% of all reports. In a <br />retrieval test, information is to be traced back to the original scans or <br />data recording. Checks are to be made for accessibility, cross- <br />referencing, accuracy of calculations and recording, and for recording of <br />work order numbers, dates, and other means of identification. Findings are <br />to be recorded and submitted to the laboratory director. <br />6.4 Laboratory Checks <br />The laboratory director (or designee), QA/QC officer are to check the <br />lab monthly for safety, proper use and calibration of instruments, labeling <br />and storage of samples, treatment of standards and reagents, and laboratory <br />cleanliness. Standards and reagents are to be checked for proper storage, <br />25 <br />
