ANFO (/ ˈ æ n f oʊ / AN-foh) [1] (or AN/FO, for ammonium nitrate/fuel oil) is a widely used bulk industrial high explosive. It consists of 94% porous prilled ammonium nitrate (NH 4 NO 3 ) (AN), which acts as the oxidizing agent and absorbent for the fuel, and 6% number 2 fuel oil (FO). [ 2 ]
Its other major use is as a component of explosive mixtures used in mining, quarrying, and civil construction. It is the major constituent of ANFO, a popular industrial explosive which accounts for 80% of explosives used in North America; similar formulations have been used in improvised explosive devices.
They are explosives based on ammonium nitrate, with other ingredients such as paraffin wax, aluminum and dinitrotoluene. The inclusion of these additional ingredients creates a more stable explosive. Nitramex and Nitramon have in modern times been replaced by more advanced high explosives based on ammonium nitrate, such as ANFO.
1988 Kansas City explosion: On 29 November 1988, at 4:07 AM two trailers containing approximately 23,000 kg (50,000 lb) of the explosive ANFO (ammonium nitrate with fuel oil) exploded at a construction site located near the 87th street exit of Highway 71 in Kansas City, Missouri. The explosives were to be used in the blasting of rock while ...
The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure. The pressure can be calculated using Chapman-Jouguet theory from the velocity and density.
The explosives factory was later operated by AECI (African Explosives and Chemical Industries). The demand for the product came mainly from the country's vast gold mines, centered on the Witwatersrand. The factory at Somerset West was in operation in 1903 and by 1907 it was already producing 340,000 cases, 23 kilograms (50 lb) each, annually.
A common chemical used for explosives was discovered by the FBI in a Texas storage locker linked to Bourbon Street terrorist Shamsud-Din Jabbar, who the agency has identified as the person who ...
A Maryland law intended specifically to ban the sale or ownership of consumer products containing binary explosive components (such as Tannerite brand rifle targets) became effective on October 1, 2012, and expanded the definition of an explosive to include, in addition to "bombs and destructive devices designed to operate by chemical ...
