Resalto lo que dice en lalgunos parrafos:
Quote:e. The post blast and uninitiated explosive exhibits were packaged in
polyethylene bags and transported together in one envelope. Polyethylene
is permeable to explosive vapours such as nitroglycerin and the presence of
nitroglycerin in just one exhibit has the potential to contaminate one of
more of the others. Our investigators are instructed to use
nylon/polyethylene exhibit bags or glass or metal containers and to store
and ship post blast and uninitiated explosive exhibits separately.
The exhibits were shipped in polyethylene bags which are permeable to volatile explosives such as
NG. Clean, airtight + impermeable containers should be used. Investigators submitting exhibits to
this laboratory are instructed to ship post blast + uninitiated exhibits separately.
I would change how the items were shipped in for analysis. The bags used to contain the items were
polyethylene, which nitroglycerin has been known to difuse through and contaminate other
specimens. You should switch to a nylon bag or kapok bag and also use a pink antistatic bag. Also,
all of the items were HEAT SEALED which could be a problem with bulk explosives!
