Is Ammonium Nitrate Flammable Or Explosive? Texas City & Lebanon Accident

Ammonium nitrate is not combustible under typical applications as well as is ruled out a fire danger, however will certainly sustain combustion in an existing fire by liberating oxygen— even if surrounded.

It is because of this that discharges entailing ammonium nitrate can not be snuffed out by the prevention or air access (for instance,
smoldering with steam) as a result of the in situ provision of oxygen from the ammonium nitrate itself.

Thermal decay may lead to hazardous gases, such as oxides of nitrogen and ammonia, being generated.

After combustion ammonium nitrate can be severely hazardous due to the white, orange, or brown fumes of hazardous oxides of nitrogen.

A fire anywhere is a reason for problem, however a fire at a plant food plant is a potential disaster. Ammonium nitrate is a highly eruptive substance, as revealed by the substantial fireball at a plant food plant in the community of, Texas (17 ).

Nitrogen, phosphorous, as well as potassium are essential plant nutrients, as well as plant foods are rated by the quantities of these elements fertilizers consist of.

Ammonium nitrate, or NH4-NO3, is frequently included in enhance a plant food’s nitrogen material. It’s reasonably stable under most problem and also is inexpensive to produce making it a prominent choice to various other, extra expensive, nitrogen resources.

The lethal disadvantage of ammonium nitrate is if it can be found in contact with an open flame or various other ignition source, which triggers a terrible explosion. The eruptive pressure takes place when solid ammonium nitrate breaks down really rapidly into two gases, laughing gas and also water vapor.

The most dangerous industrial crash in united state background occurred in the port of Texas City, Texas, in 1947. A thoughtlessly thrown cigarette began a fire aboard a ship carrying concerning 2,300 lots (2,086,000 kgs) of ammonium nitrate packed in paper sacks.

When the chemical took off, it caused a blast effective sufficient to knock people to the ground in Galveston, Texas, 10 miles (16 kilometres) away.
