Partner with specialists like Mercury to simplify your supply chain and focus on your core business.
Why GMP Compliance Matters for Biologics
Biologics storage plays a crucial role in maintaining product integrity throughout the pharmaceutical supply chain. Monoclonal antibodies, vaccines, and cell therapy products lose potency when stored outside specified conditions. A single temperature excursion can destroy months of research or render life-saving treatments unusable.
GMP warehousing provides the regulatory framework that protects high quality pharmaceutical products from receipt through distribution. FDA regulations under 21 CFR Parts 210 and 211 establish mandatory requirements for storage facilities.
Selecting the right storage partner affects patient safety, regulatory standards, and operational efficiency. This checklist guides pharmaceutical companies through essential criteria for warehouse evaluation.
Temperature Control Infrastructure
Temperature-sensitive products require precise maintenance across multiple temperature ranges. Your warehouse must demonstrate validated control systems for each storage category your products need.
Evaluate whether the facility maintains 2°C to 8°C refrigerated zones for standard biologics. Confirm capacity for -20°C frozen storage conditions when your pipeline includes certain vaccines or enzymes. Ultra-low temperature capabilities at -80°C support sensitive products and research materials requiring the desired temperature.
Request documentation showing temperature mapping studies across all storage areas. These studies reveal hot spots, cold zones, and areas vulnerable to external influences. Professional facilities conduct mapping during extreme seasonal conditions to verify year-round performance.
Temperature-controlled shipping begins at storage. Loading docks and staging areas require the same environmental controls as primary zones.
Real-Time Monitoring Systems
Continuous monitoring catches problems before they damage your products. Modern facilities deploy networked temperature sensors that track environmental conditions around the clock and ensure compliance with GMP standards.
Ask potential partners about their alert thresholds and response protocols. Effective systems trigger alarms when readings drift toward acceptable limits, not after violations occur. Quick response reduces the risk of product loss.
Data logging creates the audit trail regulators expect. Calibrated sensors must record readings at intervals short enough to detect rapid changes. Backup systems protect against primary failures and sensitive data loss.
Documentation and Traceability
Good Distribution Practice requires complete documentation for every product movement. Your warehouse partner must maintain batch-level traceability from receiving through shipping with clear roles and responsibilities defined.
Review their standard operating procedures for incoming shipments. Staff should verify conditions, inspect packaging integrity, and confirm product identity before acceptance.
FEFO inventory management ensures products ship in the correct sequence based on expiration dates. Electronic records must meet FDA 21 CFR Part 11 requirements for data integrity and prevent data breaches.
Facility Security and Access Control
High-value biologics attract security concerns beyond typical warehouse operations. Your partner should implement multiple layers of protection against theft, tampering, and unauthorized handling.
Evaluate access control systems for restricted storage areas. Biometric authentication or keycard systems grant access only to authorized personnel with individual accountability.
Video surveillance should cover all storage areas, loading docks, and entry points. Recording retention policies must align with your quality agreement requirements and regulatory compliance obligations.
Environmental Controls Beyond Temperature
Temperature represents only one environmental factor affecting biologics' stability. Humidity, light exposure, and air quality also impact therapeutic materials, similar to how food products require controlled environments.
Humidity control prevents condensation that damages packaging and labeling. Most biologics require storage at controlled humidity levels below 60%.
Light-sensitive products need protection from UV exposure. Air handling systems and the HVAC system should maintain positive pressure and HEPA filtration to prevent contamination.
Pest Control and Contamination Prevention
Contamination risks extend beyond environmental factors. Comprehensive pest management programs protect products from physical contamination.
Request documentation of integrated pest management programs. Effective facilities combine preventive measures, monitoring, and targeted interventions.
Material segregation prevents mix-ups between different products, lots, or statuses. Quarantine areas for incoming products and rejected materials require clear separation.
Staff Training and Qualification
Personnel competency directly impacts GMP compliance. Warehouse staff handling biologics need specialized training.
Training should cover GMP principles, temperature-sensitive handling, documentation practices, and emergency response.
Ongoing competency programs keep skills current. Annual requalification addresses regulatory updates and facility-specific procedures. Training records must demonstrate completed requirements.
Emergency Response Capabilities
Equipment failures and power outages happen despite preventive maintenance. Your warehouse partner needs robust contingency plans to protect products during emergencies.
Review their backup power systems. Uninterruptible power supplies bridge short outages while generators provide extended coverage.
Emergency product transfer protocols outline steps when primary storage becomes compromised. Communication procedures should notify customers promptly when events affect their products.
