Never Move In-Process Containers Without Lids or Covers in GMP Zones

Never Transfer In-Process Containers Without Lids in GMP Areas

Remember: GMP requires all in-process material containers to be fully covered before any movement to avoid contamination and ensure traceability.

Why This Matters in GMP

Open containers containing raw materials, intermediates, or in-process products are highly susceptible to contamination during handling or transfer. Airborne particles, microbes, fibers, or even insects can enter the open surface, especially in shared or transitional areas. Movement increases this risk due to turbulence and vibration. Operating with open containers not only compromises batch integrity but also increases the likelihood of environmental deviations and failed batch investigations. GMP demands complete material protection during all stages of manufacturing, including temporary holds and intra-departmental transfers.

Regulatory and Compliance Implications

FDA 21 CFR Part 211.113 and 211.65 mandate control of contamination and require equipment to be operated in a manner that prevents compromise of materials. EU GMP Chapter 5 stresses proper handling of materials and prevention of cross-contamination. WHO GMP and Schedule M require that in-process material containers be labeled, closed, and cleaned as per procedure. During inspections, auditors look for material handling logs, container integrity, and deviation reports tied to transfers. Instances

of uncovered material movement often result in citations under poor manufacturing practices.

Implementation Best Practices

Use tamper-evident, cleanroom-grade covers or lids for all containers with in-process materials.
Train personnel to always inspect lid integrity before moving containers.
Include container closure checks in the batch manufacturing record (BMR) and area clearance logs.
Utilize color-coded, dedicated lids for different manufacturing zones to avoid cross-contamination.
Implement a material transfer SOP that requires QA or supervisory verification of lid presence before movement.
