Pharmaceutical Cleanroom Mop Cleaning SOP (GMP)

1. SOP Overview: Scope and Personnel

This cleanroom mop SOP defines the standardized methodology for floor and wall disinfection within classified life science environments. Adherence ensures consistent bioburden reduction and prevents cross-contamination between cleanroom grades.

• Personnel: Only personnel successfully trained in cleanroom gowning and aseptic technique may perform this SOP.
• ਬਾਰੰਬਾਰਤਾ: As per the site-specific Master Cleaning Schedule (MCS).
• Control: This document is a controlled reference; all updates must undergo QA impact assessment via supplier-aligned change control.

2. Materials & Preparation

Success in cleanroom disinfection starts with material integrity. Preparation must occur in a controlled manner prior to entering the critical zone.

• Mop Selection: Use sterile, double-bagged polyester or microfiber mops for Grade A/B. Verify ਬੈਚ-ਪੱਧਰ ਦੇ ਦਸਤਾਵੇਜ਼ before use.
• Disinfectant: Prepare agents (IPA, Quats, Peroxides) according to the validated concentration specified in the site SDS.
• Saturation: Ensure mops are adequately wetted but not dripping. For pre-saturated mops, follow the "first-in, first-out" (FIFO) logic to maintain chemical efficacy.

3. Wiping Technique: Pattern and Pressure

ਦ pharmaceutical cleaning procedure mop technique focuses on removing contaminants rather than redistributing them. Avoid "scrubbing" motions which can generate particles.

• Unidirectional Strokes: Use long, straight strokes. Each new stroke must overlap the previous one by approximately 20%.
• "S" Pattern: When using a swivel mop head, maintain a continuous "S" motion to capture particles at the leading edge.
• Changeover Frequency: Change the mop head every 15–20 m² or whenever visible soiling is present. Never return a contaminated mop to a clean disinfectant bucket.

4. Disinfectant Contact Time & Rotation

Disinfection is a chemical reaction requiring time. Surfaces must remain visibly wet for the full duration of the disinfectant contact time validated by the facility.

Rotation Logic: Perform a weekly or monthly sporicidal "hit" to prevent the development of resistant microflora, documenting each cycle in the cleaning log.

5. Sterile Handling & Aseptic Transfer

In high-grade zones, the sterile mop procedure must include strict transfer protocols:

• Opening: Use "peel-back" methods to remove the outer bag at the airlock boundary. The inner bag is removed only within the cleanroom.
• Isolation: If a mop head touches the floor accidentally (when cleaning walls) or contacts a non-sterile surface, it must be discarded immediately.
• Gloving: Sanitize gloves with sterile IPA after every mop head change.

6. Documentation & Records (Audit-Ready)

In the eyes of a GMP auditor, "if it isn't documented, it didn't happen." Every cleaning session must be recorded with 100% traceability.

• Logbook Fields: Room ID, date/time, disinfectant lot number, mop batch number, and operator signature.
• Second Person Verification: Grade A cleaning must be witnessed and co-signed by a supervisor or QA lead.
• Deviation Management: Record any EM (Environmental Monitoring) excursions or instances where contact time was not met, initiating a CAPA if necessary.

7. Training & Visual Aids

To ensure SOP compliance, facilities should post "SOP Quick Cards" at gowning exits. These cards should visually demonstrate the stroke pattern and list required contact times.
