Ammogex / ANFO
Ammogex / ANFO Safety Sheet
A mixture of Ammonium Nitrate and Fuel Oil(ANFO).
ANFO Explosives are classed U.N. Division 1.1.
i.e. Substances which have a mass explosion risk.
a) Personnel handling explosives must be trained in their use.
b) Personnel should be trained in lifting/handling.
c) Gloves should be worn when handling exposed explosives.
First Aid Measures
Because of the fuel content, ANFO can cause dermatitis. Contact with the skin – wash thoroughly with water. Do not ingest.
Fire Fighting Measures
Fires involving explosives must NOT be fought. An area of at least 300 metres around the fire should be evacuated and the site of the fire must not be approached until it is absolutely certain that the fire is out.
Accidental Release Measures
Spillages of ANFO should be carefully lifted and, preferably put into a drill hole for disposal by detonation: if this is not possible, the explosive should be destroyed in the manner described in IIE`s leaflet “RECOMMENDED METHODS FOR THE DESTRUCTION OF EXPLOSIVES & ACCESSORIES”.
Handling & Storage
Explosives must be handled with care and not subject to naked flame, friction or shock. Smoking whilst handling explosives is forbidden. Explosives may only be stored in licensed premises.
Exposure Controls / Personal Protection
When handling exposed ANFO, personnel are advised to wear suitable gloves, see “FIRST AID MEASURE” above.
Physical and Chemical Properties
ANFO is a relatively free-flowing material, consisting of white prills and having a distinctive fuel oil (diesel) smell. ANFO has no water resistance and when exposed to moisture will dissolve leaving an oily residue which is non-explosive.
The colour is white with a slight pink tinge.
Ammogex is sold in 25kg bags. The density varies from 0.8 to 0.9 gms/cc. (For further information see the relevant Product Information Sheet).
Stability and Reactivity
The shelf life of these explosives, stored in good condition is at least one year.
There is no known toxic hazard from these explosives.
When burned, these explosives give off some nitrous fumes. Should the explosives be exposed to moisture, the ammonium nitrate will dissolve releasing nitrates and free fuel oil.
See above under “Accidental Release Measures”.
The Transport of Explosives is Controlled.
