DAF Form 7504: Biologicals/Re-icing/Refrigeration Log PDF – The Department of the Air Force (DAF) Form 7504, officially titled Biologicals/Re-icing/Refrigeration Log, serves as a critical document in U.S. Air Force air transportation and logistics operations. It tracks the handling, temperature monitoring, re-icing, and refrigeration of perishable, biological, medical, or temperature-sensitive items during transport.
Military personnel, especially those in aerial port operations, cargo movement, and air transportation roles, use this form to maintain strict chain-of-custody and environmental controls for items that require continuous refrigeration or freezing, such as biological samples, vaccines, blood products, food provisions, or other perishables.
What Is DAF Form 7504 Used For?
In Air Force cargo and passenger operations governed by DAFI 24-605 Volume 2, Air Transportation Operations, DAF Form 7504 provides a standardized log for documenting re-icing, refrigeration, and freezing activities. It ensures compliance with safety, quality, and regulatory standards for handling items vulnerable to temperature excursions.
Key uses include:
- Logging re-icing of refrigerated or frozen cargo during ground handling and airlift.
- Recording temperature checks and refrigeration status for biological materials and medical supplies.
- Maintaining an auditable record to prevent spoilage, ensure patient safety (in the case of medical logistics), and support food safety protocols.
- Supporting accountability during multi-leg transports or extended ground times where dry ice or mechanical refrigeration may need replenishment.
The form appears in the list of standard DAF forms alongside related documents like DAF Form 7503 (Aircraft Ground Handling Record) and DAF Form 7505, highlighting its role in the broader air transportation workflow.
Who Needs DAF Form 7504?
Primary users include:
- Aerial Port Squadrons (APS) and Traffic Management Offices (TMO) personnel.
- Load teams, ramp supervisors, and passenger service agents involved in cargo loading/unloading.
- Medical logistics specialists handling biologicals or temperature-controlled pharmaceuticals.
- Unit-level logisticians responsible for perishable or frozen rations and supplies.
The form applies across the Department of the Air Force, including Regular Air Force, Air Force Reserve, and Air National Guard components involved in air transportation operations.
How to Complete DAF Form 7504?
Although specific field-by-field instructions appear directly on the form (available as a fillable or printable PDF), typical refrigeration/icing logs in military airlift operations capture:
- Date and time of each check or re-icing action.
- Item description (e.g., biological samples, frozen meals, medical cargo with NSN or lot numbers).
- Container or pallet identifier.
- Initial and current temperature readings (refrigerated vs. frozen ranges).
- Dry ice quantity added or remaining.
- Re-icing or refrigeration method applied.
- Ambient temperature and any deviations or corrective actions.
- Operator/inspector name, rank, and signature for accountability.
Personnel should follow any unit-specific supplements or local procedures while adhering to overarching guidance in DAFI 24-605V2. Accurate, timely entries help demonstrate compliance during inspections or audits related to food safety, medical standards, or cargo integrity.
Pro Tip: Always use the most current version of the form from the official source to ensure you meet the latest requirements.

Related Guidance and Best Practices
- DAFI 24-605V2, Air Transportation Operations (updated as of 2025 with Change 1 and subsequent guidance memoranda) provides the primary policy framework. It references DAF Form 7504 in the context of cargo handling procedures for temperature-sensitive items.
- Personnel must maintain records per Air Force records management policies.
- For temperature-controlled cargo, integrate this log with broader cold chain management practices to prevent excursions that could compromise mission effectiveness or safety.
Proper use of DAF Form 7504 supports operational readiness by ensuring that critical biological, medical, and perishable supplies arrive in usable condition—whether for humanitarian missions, contingency operations, or routine sustainment.
Why Proper Refrigeration Logging Matters in the Air Force?
Temperature excursions can render biological materials ineffective or unsafe, spoil food rations, or compromise medical readiness. In a global mobility environment with varying climates and long transit times, standardized logging provides:
- Traceability for quality assurance.
- Defense against regulatory or safety findings.
- Data for process improvements in airlift logistics.
Units are encouraged to train load teams and cargo handlers on consistent use of the form as part of pre-mission briefs and safety protocols.
