What To Do If You Find Unexploded Ordnance

report and evacuate immediately

If you find unexploded ordnance, stop all activity immediately and back away without disturbing the object or surrounding area. Don’t touch it, move it, or assume it’s inert based on appearance — corroded casings can make explosives more volatile, not less. Evacuate using your exact entry route, warn others to stay clear, and call 911 immediately. Every decision you make from this point forward directly affects whether everyone walks away safely.

Key Takeaways

  • Stop all activity immediately, back away carefully without disturbing the object, and evacuate using the exact path you entered.
  • Never touch, move, or attempt to transport unexploded ordnance, as this can trigger fatal detonation.
  • Mark the location using visible landmarks, GPS coordinates, or barriers to prevent others from entering the area.
  • Call 911 or 112 immediately, providing your name, location, and a clear description of the object.
  • Remain at a safe distance and wait for trained EOD professionals to arrive and authorize re-entry.

Why You Should Never Assume Old Ordnance Is Harmless

One of the most dangerous assumptions you can make is that old ordnance has degraded beyond the point of detonation. Historical context confirms that unexploded bombs, shells, and grenades from both World Wars remain fully functional decades after initial deployment.

Corrosion doesn’t neutralize explosive compounds — it destabilizes them, making detonation triggers increasingly unpredictable and sensitive to minor disturbances.

Rust doesn’t make explosives safer — it makes them angrier, more volatile, and far less predictable.

You’re dealing with devices engineered for maximum destructive yield. Age doesn’t diminish that capacity; it complicates it. Degrading casings can leak toxic compounds into surrounding soil, creating environmental hazards alongside physical ones.

Understanding this historical context reinforces why safety protocols exist — not as bureaucratic formality, but as life-preserving frameworks. Dismissing ordnance as harmless because it looks old is a decision that’s cost countless lives.

Don’t make it yours.

What Does Unexploded Ordnance Actually Look Like?

Unexploded ordnance appears in many forms, including artillery shells, aerial bombs, mortar rounds, grenades, landmines, and naval mines, each with distinct physical characteristics.

You can often identify suspected ordnance by its cylindrical or spherical metal casing, tail fins, fuse mechanisms, or corroded yet structurally intact body — features that distinguish it from ordinary debris.

If you spot an object with these characteristics, treat it as live ordnance regardless of its age or apparent condition.

Common Ordnance Forms

Identifying unexploded ordnance (UXO) in the field requires recognizing a broad range of forms, since military munitions vary considerably in size, shape, and condition. Munitions types include artillery shells, mortar rounds, aerial bombs, grenades, naval mines, and anti-personnel landmines.

Historical context matters here — ordnance from both World Wars remains buried across Europe, Asia, and the Pacific, still lethal decades later.

You’ll encounter items ranging from small, fist-sized projectiles to large cylindrical bombs exceeding several feet. Detection methods like metal detectors and ground-penetrating radar help professionals locate buried threats, but you shouldn’t attempt amateur recovery.

Handling procedures are strictly reserved for trained EOD personnel. Community awareness and environmental impact considerations drive proper disposal techniques, since degrading explosives contaminate soil and water.

If it looks suspicious, treat it as live.

Visual Identification Clues

Knowing what ordnance looks like in the field builds directly on recognizing its many forms. Sharp visual cues and reliable identification techniques help you assess what you’re dealing with from a safe distance.

Watch for these defining characteristics:

  • Cylindrical or finned metal objects partially buried or surface-level
  • Corroded, greenish, or rust-covered casings indicating aged munitions
  • Fuse mechanisms or detonator caps protruding from one end
  • Stenciled markings, lot numbers, or color-coded bands on the casing
  • Unusual weight distribution visible through soil displacement or impact craters

You don’t need to confirm it’s live ordnance to act. If something matches even two or three of these indicators, treat it as dangerous and evacuate immediately.

Stop Everything and Back Away Immediately

If you suspect you’ve encountered unexploded ordnance, stop all activity immediately and back away without disturbing the surrounding area.

Halt all machinery to eliminate vibration risks, and don’t touch, strike, or attempt to move the object under any circumstances.

Follow established safety protocols by retracing your exact arrival route during evacuation procedures — this minimizes contact with any additional hazards you haven’t yet identified.

Keep everyone else out of the immediate area, including children, animals, and bystanders.

Maintain a minimum safe distance and use visible landmarks or GPS coordinates to mark the location without approaching closer.

Your personal safety and the safety of others depend entirely on your restraint.

Any disturbance, however minor, can trigger detonation, resulting in fatal consequences.

Keep People Away From the Ordnance Site

Once you’ve backed away from the ordnance, immediately warn everyone in the vicinity to stay clear of the area.

Alert bystanders, coworkers, or residents with clear, direct instructions to move away and not approach the site under any circumstances.

You’re responsible for preventing access until emergency responders arrive, so position yourself where you can monitor the perimeter without closing the distance to the object.

Warn Nearby Individuals Immediately

After identifying suspected unexploded ordnance, your immediate priority is warning everyone in the vicinity. Use clear warning signals and follow established evacuation procedures to protect lives efficiently:

  • Shout clear, direct warnings so nearby individuals understand the danger immediately.
  • Physically direct people away from the area without causing panic.
  • Establish a visible perimeter using landmarks, barriers, or posted individuals.
  • Prevent curious bystanders, children, and animals from approaching the site.
  • Direct evacuees along the same route used to enter the area.

Don’t rely on assumptions that others already know. Your swift, decisive communication determines whether people stay safe or wander into danger.

Take control of the situation, secure the perimeter, and keep unauthorized individuals away until professional EOD responders arrive and assume command.

Restrict Access to Area

Keeping people warned is only half the job—you also need to physically stop them from entering the danger zone. Station yourself at a safe distance and use whatever’s available—rope, caution tape, vehicles, or natural barriers—to establish a clear access control perimeter.

Direct foot traffic away from the site using visible landmarks as reference points.

Don’t rely solely on verbal warnings. People are curious, and curiosity kills near unexploded ordnance. Your safety measures must create a physical boundary that discourages entry without requiring confrontation.

Shut down nearby machinery to eliminate vibration risks, and keep animals secured.

Hold your position until emergency responders arrive and transfer authority to them. You’ve done your part—maintaining that perimeter protects everyone’s right to walk away unharmed.

How To Mark the Location Without Getting Closer

marking ordnance from afar

Marking the location of suspected unexploded ordnance accurately—without closing the distance—requires you to rely on landmarks, technology, and visual reference points.

These location marking techniques let you document precisely while maintaining a safe distance:

  • Use your smartphone’s GPS to record exact coordinates from where you stand.
  • Identify fixed landmarks—trees, structures, fences—and note the ordnance’s position relative to them.
  • Place visible markers like cones or flags at the perimeter, never near the object.
  • Photograph the surrounding area from your current position without moving closer.
  • Describe distances using natural reference points you can clearly observe.

Avoid approaching for a “better view.” Authorities need your location data, not your proximity.

Precision from a distance protects you and accelerates the professional response.

What To Tell the Emergency Dispatcher

Once you’ve recorded the location, your next move is contacting emergency services—and what you say to the dispatcher matters. Call 911 in the US or Canada, or 112/110 in Europe.

Effective dispatcher communication requires specific, calm delivery. State your name, exact location using GPS coordinates or landmarks, and describe the object’s size, shape, and condition without speculation. Tell the dispatcher you haven’t touched or disturbed it.

Follow emergency protocols precisely—don’t embellish or guess at the object’s origin. Confirm whether bystanders are present and whether you’ve already evacuated the area.

Stay on the line until the dispatcher releases you. If you’re on a work site, inform your site manager simultaneously.

Never transport the item to authorities—wait for trained EOD personnel to respond.

Who To Call When You Find Unexploded Ordnance

report unexploded ordnance immediately

When you discover unexploded ordnance, three contacts take priority: emergency services, local law enforcement, and your site manager if you’re on a work location. Having the right contact numbers ready guarantees a fast, efficient response:

  • Emergency services: Dial 911 in the US/Canada or 112/110 in Europe immediately
  • Local authorities: Contact your nearest police department directly if emergency lines are congested
  • Site manager: Alert them immediately if you’re on a construction or industrial location
  • Military EOD teams: Local authorities will coordinate these specialists for large or high-explosive devices
  • Never transport: Don’t bring the ordnance to any contact — responders come to you

Stay on the line with dispatchers, follow their instructions precisely, and don’t let anyone access the site until professionals arrive.

What Happens After You Report Unexploded Ordnance

After you report unexploded ordnance, a structured professional response kicks into motion.

Police arrive first, securing the perimeter and restricting access. They’ll contact an explosive ordnance disposal (EOD) team, whose response timeline depends on location, device type, and available resources.

EOD personnel assess the item remotely when possible, using robots or specialized equipment. They’ll identify whether it’s inert or live.

From there, disposal methods vary: inert items get removed safely, while live ordnance gets destroyed on-site through controlled detonation or relocated to a designated destruction area. High-explosive devices may require military EOD involvement.

Throughout this process, you remain outside the secured zone, following authority instructions.

Once professionals clear the area, they’ll authorize re-entry. Don’t re-enter until you receive explicit authorization — that decision belongs to them, not you.

Mistakes That Turn a Discovery Into a Disaster

avoid handling unexploded ordnance

Most fatalities linked to unexploded ordnance don’t result from accidental discovery — they result from what happens next. Hazardous assumptions and ignored safety protocols kill people. Avoid these critical mistakes:

Most UXO fatalities aren’t caused by discovery — they’re caused by what survivors did next.

  • Touching or moving the item — corrosion and internal pressure changes make handling instantly fatal.
  • Striking or throwing objects at it — even indirect vibration can trigger detonation.
  • Approaching for a closer look or better photograph — distance is your only reliable protection.
  • Transporting it to authorities yourself — movement destabilizes deteriorated casings unpredictably.
  • Assuming it’s inert because it looks old or damaged — degraded ordnance remains fully capable of detonation.

You don’t get a second chance with unexploded ordnance. Every wrong decision compounds your risk.

Stop, back away, and let trained EOD professionals take control.
