Munitions are designed to injure, maim
or kill people, or to destroy equipment or
structures. Consider any encounter with
a known or suspected munition as an
extremely dangerous situation.
During construction work (e.g. clearing
vegetation, grubbing, grading, or excavation), munitions may be encountered.
This is particularly true for areas known to have once been used by the military
for munitions-related activities (e.g., live-fire training and testing, and munitions
demilitarization).
Military munitions operating buildings (e.g., munitions production and
demilitarization facilities) and any installed equipment may contain explosives
residue in high enough concetrations to present an explosive hazard. Building
features (e.g., floors, walls, drains, internal and external piping, and ventilation
systems), in which explosives residues could accumulate and present an explosive
hazard, are of particular concern. Industrial equipment, particularly equipment
with internal cavities, from facilities used in munitions production or demilitarization
operations (e.g., cast loading, milling, or steam-out) that generated explosive
residues (e.g., dust or vapors) is also of concern.
After both world wars and recently with force
realignment and modernization efforts, the
Department of Defense (DoD) closed a number
of military installations and training areas, and
returned other lands previously used for military-
related activities to public use. Because of the
live-fire training and testing required to maintain
this force, millions of acres in the United States
are known or suspected to contain military munitions in the form of unexploded
ordnance (UXO), or discarded military munitions (DMM). In some cases, munitions
constituents (e.g., TNT) may also exist in high enough concentrations to present
an explosive (detonation) hazard. Although DoD routinely made an effort to remove
any explosive hazards present before releasing land from its control, some may
remain. These explosive hazards may be found on the surface or in the subsurface.

wIll yoU Know whaT To do If yoU enCoUnTer a mUnITIon?
Areas at which DoD conducted munitions-related activities include, but are
not limited to operational and former ranges, and areas used for munitions
demilitarization. The types of explosive hazards present may differ between areas.
As an example, a former impact area may contain UXO, while a former maneuver
area may only contain DMM.
Munitions can also be found in areas
where combat operations once occurred.
Even cannon balls found on Civil War
battlefields present a potential explosive
hazard. However, for a variety of reasons
(unauthorized disposals, discarded
souvenirs) munitions may be encountered
almost anywhere.
Prior to working in areas with a history of military use, even areas where DoD
has completed an environmental response to remove any hazards detected, it is
important to familiarize yourself with the site history and potential hazards. This can
be provided through site-specific safety training. In some cases, safety officials may
determine that on-site or on-call construction support by UXO-qualified personnel
is necessary to help ensure the safety of construction workers, particularly during
ground disturbing or intrusive activities.

Remember that munitions:
• Come in many shapes and sizes.
o They could look like a:
-Pointed pipe
-Soda can
-Baseball
-Car muffler
o They may:
-Look new or old
-Be found alone or in clusters
• Should be considered extremely
dangerous regardless of size or age
• Munitions often become more
dangerous with age, not safer
Munitions may be:
• Found almost anywhere
• Clearly visible on the surface
• Buried at depths of inches to many feet
• Partially or completely hidden by dirt
or vegetation
• Found under paved areas (roads,
parking lots) or building slabs
• Underwater, in lakes, streams, or the ocean
• Exposed by natural phenomena (e.g., tides)
• Easy or difficult to recognize
While munitions are most likely to be encountered
during construction in areas where DoD conducted
munitions-related activities, they may be
encountered anywhere. To protect yourself and
your co-workers, know whether munitions-related
activities ever occurred at your work site, and learn
to follow the 3Rs: Recognize, Retreat, Report.

Recognizing that you may have encountered a munition is one of the most
important steps in reducing the potential risk of injury or death. Because munitions
pose a potential explosive hazard, they should never be touched, moved or
disturbed (handled).
wIll yoU do The rIghT ThIng when The TIme ComeS?
In 1993, a construction worker digging a trench unearthed what looked like large
bullets. He recognized the potential danger, stopped digging and notified his
supervisor. Local authorities were called. As a result of this worker’s actions, nearly
150 high explosive tank shells were recovered from a former WWI training area.
Remember, whether complete or in
pieces, any munition or suspect munition
encountered should be considered
extremely dangerous. Do the right thing!
immediately stop all operations in the
area; do not touch, move or disturb it, and
notify your supervisor or local authorities.
If you encounter or suspect you may have encountered a munition, do not touch,
move or disturb it. Instead, carefully retreat from the area by retracing your steps.
• Immediately stop all construction activities in the area, warning others of the
potential danger.
• Do not approach the munition or a suspect munition. (Some fuzes are sensitive to
changes in temperature, movement or pressure.)
• Move away from the area and keep others away from it!
Unfortunately, munitions are often popular, but potentially deadly souvenirs. Taking
a munition for a keepsake presents an immediate and real danger to you. Bringing
one home endangers your family, your friends, and your community. Don’t be
tempted.

If you encounter or suspect you have encountered
a munition, do not touch, move or disturb it. Instead,
immediately stop construction activities and move
away from the area and report what you saw.
Protect yourself, your co-workers, and the public
by immediately reporting any munitions or suspect
munitions encountered to your foreman, site
supervisor, or by calling 911.
Provide as much information as possible about what you saw and where you saw
it. This will help the police and explosive ordnance disposal personnel (usually
referred to as EOD personnel) find, evaluate and address the situation.
If you believe you may have encountered a munition, report the following:
• The area where you encountered it.
• A general description of the munition, to include:
o Its size
o Its shape
o Any readily visible markings--do not approach or handle the munition to see
the markings

don’t forget
follow the 3rs
• Munitions are dangerous and may not be easily recognizable!
• The history of your work site--know when you are working on a
former military range or disposal area!
• Never touch, move or disturb a munition!
Recognize
When you may have encountered a munition.
Retreat
Do not touch, move or disturb it, but carefully leave the area.
Report
Immediately notify the police if on land,
or the U.S. Coast Guard if at sea.
Emergency contacts:
• On land: Call 911
• At sea: Use Channel 16 (156.800 MHz)
