Securesearch,
Inc.
manufactures a chemical spray for the surface detection of the presence of
two explosives that are frequently involved in criminal bombings. If the
explosive has been handled by a person or has been transferred to a surface that
the person has handled it is detectable on the surface or on hands by a
color-test spray.
The two explosives this spray can detect are TNT (Trinitrotoluene) and
DNT (Dinitrotoluene). The spray is a clear and colorless liquid mist that is
applied to the hands or suspect transfer surface by means of a pump atomizer
bottle. There is no gas propellant in the bottle that may contaminate the
atmosphere or to leak out with resultant loss of pressure. The container becomes
pressurized by several strokes to the cap. The fluid is sprayed by finger
pressure applied to a pump button on the top of the dispensing bottle. The spray
mist is directed to a surface that you suspect may be contaminated by trace
amounts of explosive. The clear liquid reacts instantaneous with either of the
two explosives it is designed to detect.
TNT
produces a red-brown color indication wherever the spray mist contacts it on the
suspect surface.
DNT
produces a blue color reaction with the detection chemical wherever the spray
mist contacts it on the suspect surface.
Over
time, the color intensity will tend to fade on the surface where the detection
chemical has been applied.
The
spray mist should not be applied to the eyes or sensitive mucous membranes, as
it is mildly irritating. If applied to the hands or other skin contact occurs it
should be washed off with soap and plenty of water. If it accidentally is
sprayed into the eyes they should be flushed out with plenty of clear cold water
and medical attention should be sought. If the product is ingested, medical
attention should also be immediately sought. A material safety data sheet (MSDS)
is available for this product. Chemical formulations are being developed to
detect other explosives and related compounds.
