DA Form 7353: Universal Safety T Guide & PDF – DA Form 7353 (often referred to as DA Form 7353-R or Universal Safety T) is a critical US Army form used in field artillery operations to document and verify safety parameters for firing. It ensures safe artillery fire by organizing key data such as quadrant elevations (QE), deflection limits, time settings, and charge-specific information. This form supports compliance with Army safety regulations during training, live-fire exercises, and combat operations.
What Is DA Form 7353 (Universal Safety T)?
The Universal Safety T is a reproducible form designed to present safety data in a clear, T-shaped format for quick reference by key personnel, including the Fire Direction Officer (FDO), Executive Officer (XO)/Platoon Leader, and howitzer section chiefs.
It is prescribed for use under FM 6-40 (and successor publications like FM 3-09.8 Field Artillery Gunnery) with TRADOC as the proponent agency. The current version dates to January 1996 (with updates referenced in later manuals), and it remains an active tool for artillery units.
Key Sections on the Form Typically Include:
- Firing Point (FP), Grid, Altitude (ALT), Azimuth of Lay (AOL), Date, Charge and Type, Angle of Fire.
- Preregistration and Postregistration Safety data.
- Shell(s) and Fuze information.
- MAX QE, DF LIMITS (deflection limits), MIN QE (with fuze types noted), MIN TI (Time of Impact or fuze settings), and MIN VT.
This organized layout allows rapid verification that fire commands stay within safe boundaries, preventing accidents and ensuring rounds impact only in authorized areas.
Purpose and Importance in Army Operations
The primary goal of DA Form 7353 is to translate range safety card data into actionable limits for the firing unit. It helps:
- Prevent friendly fire or off-range impacts by enforcing minimum and maximum quadrant elevations, deflection limits, and fuze settings.
- Support both low-angle and high-angle fire safety computations.
- Facilitate updates after registrations, meteorological (MET) changes, or position shifts.
- Ensure chain-of-command accountability under AR 385-63 (Range Safety).
In practice, the Safety T is constructed from a basic safety diagram and provides the FDO, XO, and section chiefs with the exact parameters needed to check every fire mission. It is a cornerstone of live-fire safety certification and range operations for US Army artillery units.
Who Uses DA Form 7353?
- Fire Direction Center (FDC) Personnel: FDO and chief computer compute and verify data.
- XO/Platoon Leader: Determines XO’s minimum QE for intervening crests and oversees safety.
- Howitzer Section Chiefs: Apply and verify safety limits before firing.
- Battery Commanders/OICs: Ensure overall compliance.
All key personnel must be command safety-certified per unit programs.
How to Use and Fill Out DA Form 7353?
- Obtain Range Safety Data: From the Range Officer (grid, lateral limits, min/max ranges, authorized ammo).
- Construct Safety Diagram: Plot limits on a chart or map.
- Compute Safety Data: Use firing tables (TFT), Graphical Firing Tables (GFT), or manual methods for QE, deflection, and fuze settings. Distinguish pre- and post-registration values.
- Complete the Form: Enter firing point details, charge, shells, fuzes, angle of fire, AOL, and computed limits. Note fuze types in parentheses as required.
- Verify: At least two certified personnel review computations.
- Distribute: Issue updated Safety Ts to relevant personnel; collect old ones when superseded.
- Update as Needed: After registration, MET updates, or moves.
Pro Tip: Always follow the most restrictive guidance—local range regulations take precedence over general manuals.

Best Practices for Artillery Safety
- Cross-check all data against the range safety card and DA Form 581 (ammunition request).
- Use safety aids like stakes or tape on howitzers for physical verification.
- Command “CHECK FIRING” immediately for any unsafe condition.
- Maintain thorough training and certification programs.
Proper use of the Universal Safety T reinforces the Army’s commitment to protecting personnel, equipment, and surrounding communities while maintaining mission readiness.
