3.2.1.AMMONIUM NITRATE- (AN) BASED HME s
AN is frequently used by NSAGs due to its availability from fertiliser. AN can be mixed with several fuels to produce an effective HME. Grinders and blenders are often used in its production.
ׁ WARNING. Ammonium nitrate itself is explosive if subjected to heat and / or confinement.
Prevalent examples of AN-based HMEs are:
Ammonium nitrate & aluminium (ANAL)
Silver / grey powder or granules. Odourless, may have a slight ammonia smell.
Identifiers
Figure of insensitivity 3 (FoI)
Approx. 200.
Suffers from moisture absorption. No booster required if initiated with good quality detonator.
Notes
Ammonium nitrate & fuel oil (ANFO)
Off-white to light pink granules or prills. Off-white to light grey granules or prills. Off-white to brown granules or prills. Diesel or other fuel oil odour.
Identifiers
Figure of Insensitivity (FoI)
Approx. 200.
Suffers from moisture absorption. Requires a booster charge to detonate.
Notes
Ammonium nitrate & sugar (ANS)
White powder. Off-white to light brown powder. Odourless, may have a slight sweet smell. Can attract insects due to the sugar.
Identifiers
Figure of Insensitivity (FoI)
Approx. 200.
Suffers from moisture absorption. Requires a booster charge to detonate.
Notes
3 Figure of Insensitivity is a measure of an explosive’s sensitivity. It is measured on an inverse scale with TNT having an FoI of 100.
