Calibration and <br /> maintenance of field equipment and instrumentation should be in accordance with <br /> manufacturers' specifications or applicable test specifications and should be <br /> documented. <br /> 3.3.7 Corrective Action <br /> The procedures describing how to identify and correct deficiencies in the <br /> sample collection process should be specified. These should include specific <br /> steps to take in correcting deficiencies such as performing additional <br /> decontamination of equipment, resampling, or additional training of field <br /> personnel . The procedures should specify that each corrective action should be <br /> documented with a. description of the deficiency and the corrective action taken, <br /> and should include the person(s) responsible for implementing the corrective <br /> action. <br /> ONE - 10 Revision 1 <br /> July 1992 <br />
