DA Form 7479-R: Ventilation System Inspection Checklist – U.S. Army facility managers, safety officers, maintenance teams, and contractors working on military installations rely on standardized tools to ensure HVAC and ventilation systems operate safely and efficiently. DA Form 7479-R, titled Ventilation System Inspection Checklist (LRA), is the official U.S. Army form used for this critical task. Published in December 2002 and still active through the Army Publishing Directorate, this Local Reproduction Authorized (LRA) checklist supports the commissioning, inspection, and verification of ventilation systems in Army facilities.
Whether you’re conducting routine maintenance, retro-commissioning an existing building, or verifying new construction on a U.S. military base, understanding and properly using DA Form 7479-R helps maintain compliance, protect personnel, and optimize system performance. This comprehensive guide explains everything you need to know, including how to complete the form, its role in Army technical manuals, and where to download the latest official PDF.
What Is DA Form 7479-R?
DA Form 7479-R is a one-page, fillable checklist specifically designed for inspecting ventilation systems. It falls under the series of mechanical system commissioning forms (DA Forms 7477-R through 7488-R) outlined in TM 5-697, Commissioning of Mechanical Systems for Command, Control, Communications, Computer, Intelligence, Surveillance, and Reconnaissance (C4ISR) Facilities.
- Proponent: U.S. Army Corps of Engineers (COE)
- Date: December 2002 (DEC 2002)
- For use with: TM 5-697
- LRA Status: Local Reproduction Authorized – units and facilities can print and reproduce as needed
The form ensures systematic documentation of visual, mechanical, calibration, and functional performance tests for ventilation equipment, including fans, ducts, dampers, filters, and associated controls.
Purpose of the Ventilation System Inspection Checklist
The primary goal of DA Form 7479-R is to verify that ventilation systems are installed correctly, function as designed, and meet operational and safety requirements. This supports:
- Building commissioning (new construction or major renovations)
- Retro-commissioning of existing facilities
- Routine preventive maintenance and safety inspections
- Compliance with Army safety, occupational health, and mechanical system standards
Proper ventilation is essential in Army facilities to maintain indoor air quality, control temperature and humidity, remove contaminants, and integrate with fire protection systems (e.g., fire and smoke dampers). Deficiencies identified on the checklist can prevent energy waste, equipment failure, or health hazards for service members and civilians.
TM 5-697 emphasizes that these checklists help facility managers plan, implement, test, and document mechanical systems throughout the facility lifecycle.
Key Sections of DA Form 7479-R
The form is organized into five clear sections for easy completion during on-site inspections:
Section A – Customer Data
- Plant, location, and job number
Section B – Equipment Data
- Equipment description, air loop designation, inspection date (YYYYMMDD), test equipment used, tester’s name
- Fan manufacturer, model/serial number, type, HP @ RPM, rated flow, and rated pressure
Section C – Visual and Mechanical Inspection
Checkpoints include:
- Exterior of equipment and completeness of assembly
- Equipment rotation and electrical/mechanical interlocks
- Instruments, grounding, insulation, and tightness of bolted connections
- Proper lubrication and condensate drip pans
- Sensors, controllers, actuators
- Fire dampers and smoke dampers checked
- Filters and overall cleanliness
Section D – Calibration and Set Point
- Equipment identification, bracing, labeling, safety interlocks, working space
- Anchorage, system cleaned, comparison to drawings, control system verification
Section E – System Tests
- Operating modes, temperatures, pressures, flows, levels
- Duct leak test, air balance test, coil number, control dampers, and overall system test
Each checkpoint uses simple codes:
- A = Acceptable
- R = Needs Repair, Replacement, or Adjustment
- C = Corrected
- NA = Not Applicable
Ample space is provided for notes on deficiencies and corrective actions.
How to Fill Out DA Form 7479-R? (Step-by-Step)
- Complete Section A with facility and job details.
- Enter full Section B equipment and fan data from nameplates and design documents.
- Perform the visual/mechanical inspection (Section C) and mark conditions.
- Verify calibration and set points in Section D.
- Conduct functional system tests (Section E), including airflow measurements, damper operation, and balance testing.
- Document deficiencies, corrections, and sign/date the form.
- Retain copies for commissioning records, maintenance logs, and safety audits.
Always use calibrated test equipment and follow TM 5-697 procedures. Trained personnel (e.g., qualified HVAC technicians or commissioning agents) should complete the inspection.
Why DA Form 7479-R Matters for U.S. Army Facilities?
Ventilation systems directly impact mission readiness, personnel health, and energy efficiency on Army installations. Using this standardized checklist ensures:
- Alignment with Army Safety Program requirements (AR 385-10) for workplace inspections and hazard abatement.
- Integration with fire protection and smoke control systems.
- Reduced downtime and lower long-term operating costs.
- Documented proof of compliance during audits or safety inspections.
Whether at a stateside garrison or overseas installation, consistent use of DA Form 7479-R supports the Army’s commitment to safe, reliable facilities.
