Silica Coated NESTT
Molten silica rapidly solidified was chosen for it purity and lack
of vapor pressure as a base for this type of NESTT. Pure silica being
essentially transparent and odorless, this type of NESTT can be considered
the closest thing to delivering the scent of pure explosive to the
K-9. This is particularly important in the initial imprint training
it is desirable to keep distractive odors to a minimum. The coating
is accomplished by a patented method in which explosive is dissolved
in acetone and mixed with silica. The mixture is tumbled and the acetone
driven off leaving pure explosive crystals fixed to the outside of
granules. The texture of Silica Coated NESTT is similar to beach sand
and is impervious to extremes of environmental temperatures.
Silica Coated NESTT in Training Tins
XM Training Tins containing silica coated NESTT are the most convenient packaging for training and maintenance. Each tin contains 0.035 lb. (16g) of NESTT. The tin is made up of three parts, perforated training lid, storage lid, and base. All parts are of raw aluminum. Explosive type contained in the tin is stamped on the perforated lid. Batch code for the NESTT material is stamped on the bottom of the base. After loading and assembly, the unit is place into a resealable foil lined storage bag and heat-sealed. This vapor proof bag is designed to act as a storage magazine for NESTT products and prevents cross-contamination. Each bag is labeled for content and has place to record date of first and last use.
Use of Training Tins
To avoid cross-contamination and inadvertent transfer of explosive
scent, we suggest prior to opening the foil storage bag and during use
of the training tins that you put on powderless polypropylene or latex
gloves. When you are ready to use this training aid, cut the top off
the foil bag, below the heat seal and above the ziplock feature (indicated
by the notch in the upper portion of the bag. Remove the training tin
and inspect that explosive type engraved on the lid matches label on
bag. Remove perforated lid. Next remove storage lid by holding base
firmly against a horizontal surface, such as a table top and with the
other hand pinch the storage lid flange and base and gently pull upwards.
Place the storage lid back into the bag during training session. Replace
perforated lid onto base. You are now ready to locate the training tin
into position for training. Use care to keep shaking the training tin
or rotating more than 90 degrees from horizontal to avoid spilling contents.
Silica Coated NESTT in Cloth Bags
For scenarios requiring a larger explosive representation than training
tins contain, silica coated NESTT in cloth bags increase the game by
a factor of ten. Each bag contains 0.35 lb. (160g) of silica coated
NESTT. Bags are made of raw cotton, washed prior to sewing in hot water
only. Labeling of the bags is accomplished by sewing a ribbon loop in
one corner of the bag with explosive designation imprinted. As with
all XM K-9 NESTT products, assembly conditions are configured to avoid
cross-contamination from other explosive types and avoid imparting other
secondary odors. Each cloth bag is shipped in foil storage bag and labeled
accordingly. Also available are cloth outer bags. These bags are used
as a protective covering to help extend the useful life of the inner
bag containing NESTT. The outer bags are made from the same material
as the bags containing NESTT and have a brass metal zipper. Five ribbons
with each explosive designation are shipped with the outer bag. It is
recommended that an outer bag be designated for sole use with each type
of NESTT containing inner bag. As a reminder, the ribbon with correct
designation can be tied through the hole in the zipper finger grip.
To clean outer bag, wash separately in plain hot water.
Silica Coated NESTT in Bulk
Bulk packaged 2 pounds (907g) per quart metal can. By weight, this
is the most economical unit. It is suitable for improvised training
aids calling for scenarios in which large amounts of explosives would
be present. Empty XM Training Tins #21002 can be filled by users from
this bulk supply.
Petrolatum Suspension NESTT
Convenience in the field, was the idea behind Petrolatum Suspension
NESTT. In this material, explosive is dispersed into petrolatum, a light
wax more commonly known as Vaseline™. The result is a material
with the consistency of toothpaste. It will adhere to virtually any
surface and is insoluble in water. It comes packaged 0.26 lb. (120g)
in metal tubes. The tubes act as their contents own vapor proof storage
Use of Petrolatum NESTT
Having a base made from between 92-96% light wax, the viscosity of
Petrolatum Suspension NESTT is susceptible to temperature. At temperatures
exceeding 100F (38C), the material will become fluid. At temperatures
below 65F (18C), the material will become viscous to the point where
it will be difficult to squeeze out of the tube without the crimped
seal from opening. It is suggested to store the tube at temperatures
between 65F and 90F prior to use and as noted above powderless polypropylene
or powderless latex gloves should be used when handling this material
to avoid handler contamination.
XM Training Aids Accessories
These products round out the NESTT line by providing packaging for
use with NESTT training aids, bulk NESTT, distractors, and equipment
for staging training exercises.
What it’s made of
XM NESTT (Non-hazardous Explosive for Security Training and Testing) provides the K-9 with the scent of pure explosive through two delivery methods, coated silica and petrolatum suspension. In both systems, pure explosive is used at the following percentages by weight:
At these levels, the explosive content has been certified non-explosive
by the United States Department of Transportation (DOT) for the purpose
of transportation. The remainder of these formulas is made entirely
of either pure silica or USP grade petrolatum (Vaseline).
