Unexploded ordnance (UXO) is most likely to be encountered on military or former military sites. UXO poses risk of injury or death to anyone in the vicinity. Safety measures include:

Situation Awareness

  • Early identification of potential UXO is the first and most important step in reducing risk posed by UXO.
  • Many types of UXO may be encountered:
    • Small arms munitions
    • Guided missiles
    • Rockets
    • Projectiles
    • Mortars
    • Bombs
    • Grenades
    • Sub munitions
  • UXO may be found fully intact or in fragments – NOTE: ALL UXO presents a potential hazard and should be treated as such.
  • Deteriorated UXO presents a particular hazard because it may contain chemical agents that could become exposed.

Hazard Control

  • If you see UXO, stop and do not move closer.
  • Isolate and clearly mark the area.
  • Deny entry to others.
  • Never transmit radio frequencies near UXO.
  • Never remove anything near UXO.
  • Never touch, move, or disturb UXO.
  • Keep a minimum of 1000 feet away from areas on fire that contain suspected UXO.
  • Report discovery of UXO to your immediate supervisor and/or dispatch.
  • U.S. Army Operations Center for incidents involving explosives and ammunition: (703) 697-0218.

Information on UXO can be found in the gray section of the Incident Response Pocket Guide, PMS 461.
