Adams is a security consultant in Washington since 1972. His partner, Jarro, is a Dutch Shepherd. Dutch Shepherd Dogs are commonly used for
explosive detection work. International
Detection Canine Foundation (IDCF) certifies this team as an explosive
detection team.
Detection
dogs are selected for their drive and keen sense of smell. Dogs with long snouts and plenty of exposed
nose tend to have a keener sense of smell.
The farther up a dog’s nasal passage the more discriminating the alveoli
is.
Therefore
Labrador Retrievers, Golden Retrievers, Malinois, Dutch Shepherds, and German
Shepherds are commonly used as detector dogs.
Many individuals from these breeds display vigorous drive and they all
have physical characteristics providing a long nasal passage.
Scent
constantly tries to flow from higher concentrations to lower concentrations. To this end odors will bleed through
containers and a detector dog will find it.
Several factors can influence this including temperature, humidity, and
barometric pressure.
Everything
has an odor. Some things are just
odorless to people.
There
are literally thousands of explosives, combinations, mixtures, and
compounds. This is not to say that an
Explosive Detector Dog (EDD) must detect and discriminate thousands of
explosives.
All
commonly used commercial and military explosives contain products that are
found in five common explosive families.
All these explosives, combinations, mixtures, and compounds contain at
least one of the explosive families.
Any
of a number of other ingredients can be added to an explosive mixture. Some of these ingredients are intended to
enhance the explosive nature of the product.
These products are not detectable when found alone. But these very same products pose no threat
when found alone. An EDD will ignore
those added odors and search only for the explosives.
Therefore
an EDD need only detect and discriminate the five explosive families in order
to detect all the commonly used commercial and military explosives.
Some
certifying and accreditation agencies allow EDDs to certify with a reliability
rate as low as 92%. Others require a
demonstrated reliability of 100%.
Simply because an EDD has a reliability rate of 100% by no means assures
complete protection from threat of explosives.
If
an EDD is100% reliable and is only tasked to screen 50% of the luggage at a
passenger terminal the effective reliability of the screening is only 50%. If a 100% reliable EDD screens only one or
two sections of a stadium the spectators seated in that area are assured an
explosive-free environment. The
remaining spectators will not have such assurance.
In
order to maintain the effectiveness and proficiency of an EDD team, on-going
training is necessary. Maintenance
training and annual re-certification are two ways of maintaining, and
documenting, reliability.
Of
all the explosive detection and deterrent methods available an Explosive
Detector Dog is the best single technique.
Any
business or governmental organization that is realistically at risk of threat
by explosives must first conduct an assessment in order to determine their
actual needs. The assessment will allow
reasoned decisions when considering whether to add security personnel, harden a
perimeter, select training criteria, or when best to deploy an EDD.
A
comprehensive safety and security program must include combinations of tools
and techniques in order to provide the best possible protection.
Line
personnel must be selected based on their history of reliability and their
desire to assure protection. They must
be afforded adequate training and education.
Supervisory
personnel must be selected based on their proven experience, history of
reliability, their familiarity with and understanding of industry practices,
and a desire to assure protection.
An
explosive deterrent and response plan should be an integral part of any safety
and security program. Protocols and
procedures must be developed that are specific to each location.
The
EDD team is a part of the overall safety and security program. It is the essential component for an
explosive deterrent and response plan.
There
is no single preventative measure that can detect and deter the threat of
explosives. A safety and security program
that is realistic, comprehensive, and complete must be in place in order to
assure the greatest level of protection.
Program
components must include appropriate protocols and procedures for explosives
deterrence and response.
Essential
components of any explosive deterrence and response plan include a realistic
threat assessment, proper selection and training of personnel, and the proper
deployment of Explosive Detector Dog teams.
