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] The use of ANFO originated in the 1950s. [3]
As a result, two trailers containing approximately 50,000 pounds (23,000 kilograms) of the explosive ANFO were situated nearby for use as a blasting agent. [1] [2] Shortly before the explosion, at 3:40am, the Kansas City Fire Department received their first call alerting to a pickup truck fire on the construction site. The possibility of ...
Detonation cord will initiate most commercial high explosives (dynamite, gelignite, sensitised gels, etc.) but will not initiate less sensitive blasting agents like ANFO on its own. 25 to 50 grain/foot (5.3 to 10.6 g/m) detonation cord has approximately the same initiating power as a #8 blasting cap in every 2 to 4 inches (5 to 10 cm) along its ...
Solid ammonium nitrate decomposes on heating. At temperatures below around 300 °C, the decomposition mainly produces nitrous oxide and water: NH 4 NO 3 → N 2 O + 2 H 2 O. At higher temperatures, the following reaction predominates. [13] 2 NH 4 NO 3 → 2 N 2 + O 2 + 4 H 2 O. Both decomposition reactions are exothermic and their products are gas.
The fatal explosion involved at most a few tonnes of explosive. A larger explosion of about 80 tonnes of ammonium nitrate emulsion, ANE, an emulsion of ammonium nitrate, fuel and water, UN 3375) was caused by fires under storage facilities at the site at 11:02 AM. There were no fatalities in the second explosion because the site had been evacuated.
