Five containers of kilos each were used to blow up the Tax Office building in Bastia on 28 February For other cartridge forms ask EXSA. Other explosives based on the ANFO chemistry exist; the most commonly used are emulsions.
Its name is commonly pronounced as “an-fo”. In underground mining applications, ANFO is typically blow-loaded. Depending on the detonation impetus for example a 6 versus a 10 detonatorthe products of the detonation can be decidedly unstoichiometric. The fuel component of ANFO is typically diesel, but kerosenecoal dust, racing fuel, or even molasses have been used instead. Please help improve this section by adding citations to reliable sources.

In humid environments, absorbed water interferes with its explosive function. In an ideal stoichiometrically balanced reaction, ANFO is composed of about Unsourced material may be challenged and removed.
AN is highly hygroscopicreadily absorbing water from air. Therefore, since their delivery to the buyers, the manufacturer is not liable for its safety or for the achievement of the desired results, be they explicit or implicit. In most jurisdictions, ammonium nitrate need not be classified as an explosive for transport purposes; it is merely an oxidizer.
Principles and Practices of Modern Coal Mining. When used in wet mining conditions, considerable effort must be taken to remove standing water and install a liner in the borehole; it is generally more productive to instead use a water-resistant explosive such as emulsion.
While many fuels can theoretically be used, the low volatility and cost of diesel make it ideal. With its low sensitivity and excellent performance in breaking and displacing rock, it is ideal for quarries and civil works. Mines typically prepare ANFO on-site using the same diesel fuel that powers their vehicles. They must be stored in a cool, dry and well-ventilated area, handled and transported in accordance with the current legislation. They differ from ANFO in the physical form the reactants take.
In Stephen King ‘s novel Desperationnovelist Johnny Marinville prevents the rest of the group from going forward, and proceeds to blow up the Pit and the ini inside with the ANFO, sacrificing himself.
The press and other exploslvo have used the term ANFO loosely and imprecisely in describing improvised explosive devices IEDsin cases of fertilizer bombs see Malicious use below.
A larger quantity of secondary explosive, known as a primer or a boostermust be used. A total of people were killed, and 38 others injured when, within a short time, several Anvo bombs exploded near four apartment buildings.
ANFO is also widely used in avalanche hazard mitigation. The most notable properties of emulsions are water resistance and higher bulk density. From Wikipedia, the free encyclopedia.

In expoosivo countries, its purchase and use are restricted to buyers who have obtained the proper license. In explosico movie The Dark Knight by Christopher NolanThe Joker uses the compound to hold two ferries hostage, and tries to make the people on each ferry detonate the other ferry. Recommended for use in dry holes that will remain dry until detonation.
Retrieved 3 March In JanuaryPresident Hamid Karzai of Afghanistan also issued a decree banning the use, production, storage, purchase, or sale of ammonium nitrate, after an investigation showed militants in the Taliban insurgency had used the substance in bomb attacks. Retrieved 16 April Retrieved March 3, ANFO is a tertiary explosivemeaning that it cannot be set off by the small quantity of primary explosive in a typical blasting cap. Examon – P Is a blasting agent of great versatility, specially designed to deploy a high level of energy and a large volume of gas, thus achieving excellent rock fragmentation.

Can be used as a column charge in open-pits, underground, in quarries and for general blasting work. Exploslvo powdered aluminium in the mixture will sensitise it to detonate more readily.
