DA Form 7400 PDF Download | Record of Area/Equipment Survey

DA Form 7400 PDF Download | Record of Area/Equipment Survey – If you’re a U.S. Army Radiation Safety Officer (RSO), maintenance technician, or unit leader handling equipment or areas potentially contaminated with depleted uranium (DU) or other radioactive materials (RAM), DA Form 7400 is a critical document. Officially titled Record of Area/Equipment Survey, this form ensures compliance with Army radiation safety standards, documents survey results, and helps determine whether equipment or areas can be released for unrestricted use.

In this comprehensive guide tailored for U.S. Army personnel, you’ll learn exactly what DA Form 7400 is, when to use it, how to complete it step by step, and where to download the latest official fillable PDF. All information is drawn from trusted Army sources including armypubs.army.mil and DA PAM 700-48.

What Is DA Form 7400?

DA Form 7400, dated December 1999, is the Department of the Army’s standardized form for recording radiological surveys of areas and equipment. It is prescribed by DA PAM 700-48, Handling Procedures for Equipment Contaminated with Depleted Uranium or Radioactive Commodities.

The form is used to:

  • Document the discovery and assessment of radioactive contamination.
  • Record survey methods, instruments, and results.
  • Verify compliance with maximum free-release limits (detailed in DA PAM 700-48, Appendix J).
  • Support decontamination, retrograde, and disposal decisions.

It pairs closely with DA Form 7399 (Survey/Decontamination Record) for full documentation of incidents involving radioactive commodities.

Why DA Form 7400 Matters for U.S. Army Operations?

Radioactive contamination from DU munitions, damaged radioactive sources, or other RAM can occur during training, combat, maintenance, or retrograde operations. DA Form 7400 provides an auditable record that:

  • Protects personnel health by ensuring ALARA (As Low As Reasonably Achievable) principles.
  • Supports legal and regulatory compliance (AR 385-10, AR 700-48, and NRC license conditions).
  • Enables safe release, repair, or disposal of equipment and areas.

Units failing to properly document surveys risk mission delays, safety violations, or improper handling of low-level radioactive waste.

When Should You Use DA Form 7400?

Use this form whenever you conduct or document:

  • Initial or follow-up radiation surveys of equipment or storage areas.
  • Post-decontamination verification surveys.
  • Retrograde operations involving potentially contaminated vehicles, weapons, or commodities.
  • Any incident where contamination is suspected (e.g., DU strike damage, source leakage).

It is not a general maintenance or safety inspection form—its primary focus is radiological contamination control.

Step-by-Step: How to Fill Out DA Form 7400?

Follow the flow instructions in DA PAM 700-48, Appendix C-10 for best results. Here’s a clear breakdown of the form’s fields (based on the official PDF layout):

SECTION I – ESSENTIAL INFORMATION

  1. DATE OF INCIDENT (YYYYMMDD)
  2. TIME OF OCCURRENCE
  3. LOCATION OF INCIDENT
  4. GRID COORDINATES, IF KNOWN
  5. CAUSE OF CONTAMINATION (e.g., DU impact, source damage)
  6. WHEN WAS CONTAMINATION DISCOVERED?
  7. EQUIPMENT NOMENCLATURE / NSN (include serial numbers or ICRIS data as applicable)

SURVEY DETAILS

  1. SURVEY PERFORMED BY (name/rank)
  2. UNIT
  3. SURVEY INSTRUMENT MANUFACTURER AND SERIAL NUMBER (e.g., AN/PDR-77 or AN/VDR-2)
  4. PROBE TYPE
  5. CALIBRATION (status and due date)
  6. DATE (of survey, YYYYMMDD)

SECTION II – SURVEY RESULTS

  • Record actual survey readings (background, contact, 1/2-inch distance, wipe test results in DPM/100 cm² or mR/hr).
  • 14. RESULTS WITHIN RELEASE LIMITS? (Yes/No) – Reference DA PAM 700-48, Appendix J for surface radioactivity limits.

Additional Best Practices:

  • Attach DA Form 7399 if this is a follow-up survey.
  • Include photos, sketches, or wipe test lab results.
  • Have the RSO or commander sign as required.
  • Retain copies per your unit’s radiation safety program and local records retention policy.
  • DA PAM 700-48 – Primary guidance (27 September 2002 edition still widely referenced).
  • AR 385-10 – The Army Safety and Occupational Health Program.
  • DA Form 7399 – Survey/Decontamination Record (often used together).
  • DA Form 7401 – Radioactive Commodity Incident Report.
