WIN Execution Guide — Production Cleaning Verification
Non-Authoritative WIN Execution Guide Notice
This WIN Execution Guide supports execution of applicable Family Pack controls.
Authority for control intent and requirements remains solely with the
governing Family Pack. This document does not create, modify, or interpret controls.
Purpose
To support consistent verification of production cleaning completion and
suitability prior to next use, to prevent cross-contamination between batches.
Scope
Applies to production equipment and areas that require cleaning verification
prior to reuse, including changeovers, post-batch cleaning, and cleaning after
maintenance or abnormal events where contamination risk could exist.
Section 6 — AA (Auditable Artifacts)
AA-PROD-CLEAN-CHK — Production Cleaning Verification
- Equipment and area identification
- Cleaning completion confirmation
- Authorization prior to next use
- Escalation reference if criteria are not met
Auditor focus: Prevention of cross-contamination between batches.
QC-REQ Anchor: QC-ENV-002
Section 7 — WIN (Work Instructions / Control Requirements)
WIN-PROD-CLEAN
- Verify cleaning completion.
- Confirm suitability prior to next use.
Stop-Execution Condition:
- Cleaning incomplete or undocumented
- Residue or contamination identified
Control outcome: Cross-contamination risk is prevented prior to next batch.
Process: Production (PROD)
Business Process Owner: Production BPO
Primary Systems / Forms: CLEAN-CHK-01 (or equivalent cleaning verification log)
BPO-Owned Execution Zone — Operational Step Sequence
Cleaning verification is completed and documented prior to authorizing
equipment or areas for next use. Verification includes confirmation of
completed cleaning and visual suitability checks.
Step 1 — Identify Equipment and Area
- Confirm equipment ID(s) and production area subject to verification.
- Verify cleaning activity corresponds to correct equipment/area and prior operation.
- Confirm cleaning record is available for review.
Step 2 — Verify Cleaning Completion
- Confirm cleaning steps have been completed and documented.
- Verify cleaning completion time and responsible personnel attribution.
- Confirm required disassembly/reassembly steps (if applicable) are complete.
Step 3 — Confirm Suitability Prior to Next Use
- Perform visual inspection for residue, product carryover, or contamination indicators.
- Confirm equipment contact surfaces appear clean and dry as applicable.
- Verify cleaning status labels/tags reflect readiness for use.
Step 4 — Authorize or Restrict Use
- If criteria are met, authorize equipment/area for next use and document approval.
- If cleaning is incomplete, undocumented, or residue is identified, restrict use immediately.
- Escalate nonconformance through site escalation process and document reference number.
Step 5 — Document Verification
- Record equipment/area identification, date/time, verifier, and outcome.
- Document authorization for next use or restriction decision.
- Reference escalation record where applicable.
Stop-Execution Principle
If cleaning is incomplete/undocumented or residue/contamination is identified:
STOP — DO NOT USE — ESCALATE — DOCUMENT
Authority Reminder
This document supports execution only and is non-authoritative.
The governing Family Pack remains the sole source of control intent and requirements.
