Do Not Permit Floor Cleaning During Product Exposure in GMP Areas

Never Perform Floor Cleaning While Product Is Exposed in GMP Zones

Remember: Cleaning activities must not occur when products are exposed—this violates GMP and significantly increases contamination risk.

Why This Matters in GMP

Floor cleaning in GMP manufacturing areas generates aerosolized particulates, chemical vapors, and micro-droplets—all of which can settle on exposed products, raw materials, or open equipment surfaces. If such activities occur during batch processing or product exposure, the risk of cross-contamination or chemical ingress becomes unacceptably high. GMP requires that product protection be the highest priority, with cleaning restricted to periods when materials are closed, removed, or securely covered. Failure to follow this leads to compromised batch quality, rejection, or worse—patient harm.

Regulatory and Compliance Implications

FDA 21 CFR Part 211.67 mandates that cleaning procedures be designed to prevent contamination of product during manufacturing. EU GMP Annex 1 explicitly prohibits cleaning or maintenance activities during open product exposure unless justified. WHO GMP and Schedule M stress the segregation of production and cleaning operations by time and space. Inspectors will review shift schedules, cleaning logs, and BMR entries for overlap. Unauthorized cleaning during processing is treated as a serious compliance lapse and

can lead to deviation investigations or regulatory warnings.

Implementation Best Practices

Schedule floor and area cleaning during breaks, post-shift hours, or dedicated cleaning windows.
Include “Product Covered/Removed” verification as a checklist item in all cleaning SOPs.
Train housekeeping and production personnel to communicate before initiating cleaning near production lines.
Use cleaning logs to record exact time, area, cleaning agent used, and personnel initials.
Design facility layouts to enable minimal overlap between active manufacturing and sanitation tasks.
