If the person collecting -the sample does not deliver the samples containers for <br />shipment, the first block for Relinquished By , Received By ,must <br />be completed. <br />• The samples will be shipped to the laboratory by commercial carrier. The original <br />COC form is placed in the shipping container and the shipping container is sealed <br />prior to being given to the carrier. The carbonless copy of the COC form is sent to the <br />field file. The carrier waybill will serve as an extension of the COC record between <br />the final field custodian and receipt in the laboratory. <br />• Upon receipt in the laboratory, the quality control (QC) coordinator or a designated <br />representative opens the shipping containers, compares the contents with the COC <br />record, and signs and dates the record. Any discrepancies are noted on the COC form. <br />• If discrepancies occur, the samples in question are segregated from normal sample <br />storage and the field personnel immediately notified. <br />• COC records are maintained with the project records by becoming part of the <br />data/report package. <br />In addition to initiating the COC form, field personnel are responsible for uniquely identifying <br />(required on the COC form) and labeling samples, providing proper preservation, and packaging <br />samples to preclude breakage during shipment. <br />Every sample label includes the following: <br />• A unique sample number <br />• Sample Location <br />• Sampling date and time <br />• Name of person collecting the sample <br />• Method of sample preservation/conditioning <br />Shipping containers are sealed at the ends with tape prior to shipment. <br />The final step in providing information to the laboratory is the request for analysis. The request <br />for analysis section is completed by the field personnel on the COC record. The request for <br />analysis form is provided so that analytical requirements are defined and sample holding tunes <br />are not exceeded. A copy of the COC and request for analysis form is maintained in the field <br />data sheet/log. <br />7.2.2 Laboratory Sample Handling <br />The first step in the laboratory receipt of samples is to complete the log -in form. The QC <br />coordinator or a designated alternate accepts the shipment and notifies the laboratory manager or <br />designated representative of the incoming samples. <br />7-2 <br />
