Title: Cleaning Validation OBJECTIVE:
To define the minimum requirements for validation of cleaning procedures for equipment associated with the manufacture of drug products to assure that fitness for use of each end product is adequately protected. Also, this procedure established limits for acceptable cleaning levels on swab tests or rinse samples used to validate the cleaning of equipment. RESPONSIBILITY:
- Production Prod uction engineering: engineering: Equipment structure, surface area - Production Prod uction department: leaning process - !: "ampling, cleaning evaluation, analytical method validation, acceptance criteria determination - !A: #eviewing and final approval.

Approvals required for acceptance of the protocol by all the validation team and !A.
6. E/ecution of leaning 7ethod $alidation a. Perform, or have performed, equipment cleaning validation in accordance with an approved equipment cleaning validation protocol. b. (nvestigate non-conforming results. )ocument the investigation and include a description of the situation, all ancillary information and data related to the investigation, conclusions as to the probable cause, and recommended actions with rationale. c. E/ecute approved cleaning protocol %s& under conditions which reflect actual manufacturing processes. All acceptance criteria must be met for the validation to be considered complete. Any swab or rinse failures must be e/plained. 6& +or dry product operations, perform three successful consecutive cleaning validation runs for each piece of equipment listed in the protocol. 8& +or parenteral operations, successfully complete an approved cleaning protocol a minimum of three consecutive times to validation a cleaning process. 6. +inal Equipment leaning $alidation Pac9age a. The final equipment cleaning validation pac9age includes: 6& The approved cleaning validation protocol.
8& All data developed to support the validation, including data supporting adustments to the original protocol, if any. & A final summary which should include a discussion on the possible need to conduct routine monitoring studies to ensure the cleaning systems continue to perform as validated. ;& Approvals. a. The final equipment cleaning validation pac9age must be reviewed and approved by department heads of each of the following areas: Technical services and0or validation, and !. *ther areas may be added as appropriate. 6.
