Characteristics of Ammonia (NH3)
Ammonia can be found in a variety of common industrial environments. It's a colorless gas with a pungent suffocating odor. Ammonia is characterized as a flammable although it is very difficult to ignite. When exposed to heat, an ammonia solution will decompose to form ammonia gas and oxides of nitrogen (NOx). Ammonia is an irritant and will become extremely irritating to anyone exposed to it as concentrations increase.
