A bomb threat usually brings to mind a picture of a bomb hidden inside a facility, but devices may be
planted against a facility. A great amount of damage can be caused by a device planted outside a
facility. Therefore, the search must proceed from the outside to the inside, and from the bottom to the
top. These procedures have resulted from years of practical experience. This reduces the risk of injury
to both the searchers and the occupants. It is preferable to search all areas at the same time if the
search team is large enough. The following breakdown of team members has been found to be
o Outside search - 25 percent.
o Inside search - 50 percent.
o Public areas - 25 percent.
Of course, if the location of the bomb is known or suspected, the search should begin in that area.
a. Exterior Search. The search of the outside of a building is more important. This is the most
accessible area to the bomber, especially after dark. It must cover all feasible areas where a device
may have been planted. The search pattern begins at ground level. Close attention must be given to
o Window ledges.
o Piles of leaves or refuse.
o Garbage cans.
o Flower arrangements.
o Air conditioner units.
o Automobiles (extreme caution must be used when the search involves automobiles).
The search should be conducted to a distance of 25 to 50 feet from the building (see Figures 2-3, 2-4,
2-5, 2-6). After completing the ground-level
