Ammonium Nitrate (alias of 0222)

CAS RN:6484-52-2

Toxic Combustion Products

Combustion by-products include oxides of nitrogen and ammonia.

In a fire, all types of ammonium nitrate may melt and decompose with the release of toxic fumes (mainly oxides of nitrogen) which may be yellow or brown. Most types do not continue to decompose once the fire has been extinguished. However, when some types of ammonium nitrate fertilizers (cigar burners) are heated they undergo a smoldering (self-sustaining) decomposition that can spread throughout the mass to give substantial toxic fumes, even when the initial heat source is removed.
