Nuevos analisis de explosivos

[pepelui]

Bueno esto es lo ultimo que aportare (me estoy rayando ya con esto) acerca de la imposibilidad porosa.

Q. And in the United Kingdom, if you intend to test for
organic explosives, would you use ordinary polyethylene bags to
collect evidence at a bombing scene?
A. Again, the polyethylene bags aren't ideal, but they're
often used.
Q. And why aren't they ideal?
A. Some high-performance explosives, particularly the liquid
ones such as nitroglycerin, are volatile and will seep through
polyethylene bags.
Q. And nitroglycerin is one ingredient of ammonium-nitrate-
based dynamites; correct?



Linda Jones - Cross
A. Some dynamites, yes.
Q. So if one were concerned to try to identify the presence of
ammonium-nitrate-based dynamites, one would not use
polyethylene bags; correct?
A. That wouldn't be ideal, but again circumstances dictate. A
polyethylene bag is better than no bag.
Q. Understood. But in the United Kingdom, what kind of bags
do you recommend?
A. For explosive-residue analysis, wherever practical, we

recommend a different type of plastic bag, which is a nylon
bag.
Q. A nylon bag?
A. Yes.
