Ammonium nitrate has a melting point of 1700C and decomposes above 2100C. It is not in itself combustible but, as it is an oxidising agent, it can assist other materials to burn, even if air is excluded. Ammonium nitrate will not explode due to the friction and impact found in normal handling, but it can be detonated under heat and
Ammonium nitrate mixed with oil or other sensitizing contaminants may explode or detonate when exposed to fire or shock. Organic materials (e.g., packing materials, seed, etc.) will increase the likelihood of an explosion and will make the ammonium nitate explosion more energetic.

Check to make sure the respiratorUse a vacuum or a wet method to reduce dust during
The use of ammonium nitrate (AN) as an ingredient in blasting composi-tions is not new. In 1867, Ohlsson and Norrbin patented Ammoniakkrut (5, z),5 consisting of ammonium nitrate,either alone or in mixtures with charcoal, saw-dust, naphthalene, picric acid, nitroglycerin, or nitrobenzene.Since that

In the relationship between pH and ammonium/ammonia, periods that were dust-rich and mixed sulfate-nitrate-coal regions were identified according to the relative contributions of those factors (Figure 3). Table S1 shows the average source contribution (%), concentrations (μg/m 3) of NH 3 (g) and TWI, and pH in dust-rich and mixed regions.

ammonium nitrate(V) mixed with wheat flour, hard coal, rape seeds or wood dust. It was found that all of the mixtures tested decompose at significantly lower temperatures than ammonium nitrate(V) and ANFO explosive. Some of them decompose close to the melting temperature of ammonium nitrate(V) and their decomposition is violent.
However, inhalation of high concentrations of ammonium nitrate dust can cause respiratory tract irritation. Symptoms may include: coughing, sore throat, shortness of breath, or even suffocation. When swallowed in high concentrations, ammonium nitrate may cause headache, dizziness, abdominal pain, vomiting, bloody diarrhea, weakness, a tingling ...
a source of urea dust (0.5-2.2 kg/t) as is the granulator (0.1-0.5 kg/t). Particulates are the principal air pollutant emitted from ammonium sulfate plants. Most of these are found in the gaseous exhaust of the dryers. Uncontrolled discharges of particulates may be in the order of 23 kg/t from rotary dryers and 109 kg/t from fluidized bed dryers.
– Ammonium nitrate is also used in instant cold packs. In this use, ammonium nitrate is mixed with water in an endothermic reaction, which absorbs 26.2 kilojoules of heat per mole of reactant. – Products of Ammonium nitrate reactions are used in Airbags. Sodium azide (NaN3) is the chemical used in airbags, as it decomposes to Na (s) and N2 (g).

All ammonium nitrate plants produce an aqueous ammonium nitrate solution through the reaction of ammonia and nitric acid in a neutralizer. Approximately 60 percent of the ammonium nitrate produced in the U. S. is sold as a solid product. To produce a solid product, the ammonium nitrate solution is concentrated in an evaporator or concentrator.
Abstract. Results of tests conducted with 14 brands of permissible explosives and with 3 nonpermissibles to study the hazards of coal-dust ignition during blasting in coal mines show that permissible explosives will not ignite coal dust in a mine and cause an explosion when fired in a manner approved by Bureau of Mines, according to this report describing tests made.
