Day 4 Flashcards
name some sensitivity tests
drop hammer, friction, thermal, chemical
what are sensitivity test useful as
a relative indication of sensitivity
what can explosives be sensitive to
chemical, spark, mechanical, light, thermal
sensitivity of an explosive is dependent on many factors including…
impurities, molecular structure, age, humidity, particle size
“sensitivity can _____ or _____ over time
increase or decrease
what are the types of detonators
electric and non electric
how much explosive should be in a detonator for safety
the minimum amount
what are the sub-types of detonators
simple and compound
explain simple detonators
only contains primary explosives
larger quantity of explosive must be used since primary’s have low detonation pressure
describe compound detonators
minimizes quantity of primary explosives
increases the detonator strength, more reliably sets off other explosives
how much NEW should an improvised detonator contain
1 gram
what can you use for a detonator casing
vial
brass casing
battery casing
cardboard
metal tubing
pen
what are the required items for a improvised detonator
primary explosive
secondary explosive
casing
initiation stimulis
what stimulas can you use for a improvised detonator
fuse
light bulb
primer cap
resistor
name some HME detection kits
AHURA
first defender RM
field forensics idex
