Unused lines on the COC record will be crossed out ("Z"). COC records initiated in the field will be signed, placed in a resealable plastic bag and taped to the inside of the shipping container used for sample transport.

Copies of the COC record and the airbill will be retained and filed by the sampler prior to shipment. 9.1.9.19 Upon receipt of an ice chest, laboratory personnel will review the contents and will sign and retain the COC record and the airbill.
