The Control Act of 1970 also attempts to license and regulate explosives when sufficient interstate
contacts exist. Despite laws regulating explosives, there is little control over a would-be bomber's
access to explosives. The ready access to chemicals and the simple instructions set forth in the guides
mentioned above are all the technology needed by would-be bombers. Bombs are, therefore, a very
serious threat. They should not be underestimated.
Security Against the Bomber.
It may not be possible to completely keep explosive devices out of a facility. However, an active
security program will greatly increase the difficulty of the bomber.
Four security measures should be emphasized within a physical security program as control measures
against the introduction of bombs. These are identification and control procedures, package and
material control, intrusion detection systems (IDS), and closed circuit television (CCTV).
Identification and Control Procedures. The primary objective of these procedures is to be aware of who
is entering and exiting the facility and to keep persons from wandering through the facility. This can be
as complicated as automated entry control or as simple as being greeted and challenged by a
receptionist. The use of single card or badge, card or badge exchange, or multiple badge systems is
useful in the control and movement of persons into, within, and out of the facility. These measures
serve as an obvious deterrent against a would-be bomber believing an unobserved entrance may be
Package and Material Control. In conjunction with the above procedures, there should be control of
packages entering a facility. Procedures which may be used are:
o A roster of expected incoming packages.
o Verification of all unexpected items prior to acceptance.
o Sign in/out sheet of persons with hand-carried items, listing the items.
o Bomb-detector dogs.
Package control should not be limited to packages carried openly. It must include controls on articles
of clothing, handbags, briefcases, umbrellas, lunch boxes, and anything of a similar nature, which can
be used to hide bombs. Even a folded newspaper could carry a bomb or incendiary device.
Motor vehicles are another important potential bomb threat. All motor vehicles privately owned and
operated by the site personnel should be registered with the command post. Whenever possible,
parking areas for such
