Sample Handling 10.1 Refrigerator Storage and Temperature Log Samples may be stored in a refrigerator at the consulting office prior to transport to the laboratory Refrigerator storage is maintained under the following conditions • Refrigerators used for sample storage are dedicated for that usage only (no food or other materials are stored in sample refrigerators) • Refrigerators can be locked from the outside by a sample manager, and only the sample manager has access to samples while in storage • Refrigerators are maintained at temperatures between 2 to 4°C, and are adjusted dally depending on thermometer readings • Each refrigerator contains a dedicated, reliable thermometer The thermometer is designed for use in a refrigerator and is fixed/secured to the inside of the unit The thermometer range is specific for measuring temperatures in the 2 to 4° C range • A temperature log is kept on the outside of the refrigerator in a lightweight, three-ring binder, or similar logbook Temperatures are recorded dally or when the refrigerator is open for sample management • Completed CDCs are kept with the samples stored in the refrigerators The COCs may be held on a clipboard outside the refrigerator, or may be placed inside the cooler if the entire cooler is placed inside the refrigerator • If a cooler is placed in the refrigerator, the cooler lid remains open to insure that samples are maintained at the refrigerator temperature 10.2 Cooler Packing The sample coolers are packed as directed by the receiving laboratory Standard procedures for cooler packing include • The cooler contains enough ice to maintain the required temperature of 2 to 4° C (roughly 20 percent of the volume of the cooler) • Water ice (not dry ice or ice packs) is used for shipping • The ice is placed above and below the samples in at least two sealable plastic bags This requires that the packing/divider material is removed and replaced • The COC is placed in the cooler in a sealed plastic bag, and the cooler lid is taped closed to secure it for transport and to minimize loss of temperature A custody seal is placed vertically across the seam of the cooler lid Main\D\$nvironmentat\ParmarTexaco\Workplan\042003 wpd
