Chemical Properties & Uses

Ammonia is a colorless alkaline gas with a characteristic pungent odor. Ammonia is one of the most abundant nitrogen-containing compounds in the atmosphere.

Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. Ammonia is also used in the production of fertilizers, refrigerants and textiles. Other uses include water treatment and pulp & paper processing.

Ammonia is irritating and highly corrosive to the skin, eyes, nose, throat, and lungs. It is also a flammable gas at concentrations; LEL = 15% and UEL = 28% by volume air. The minimum concentration of a particular combustible gas or vapor necessary to support its combustion in air is defined as the Lower Explosive Limit (LEL) for that gas. Below this level, the mixture is too “lean” to burn. The maximum concentration of a gas or vapor that will burn in air is defined as the Upper Explosive Limit (UEL). Above this level, the mixture is too "rich" to burn.

Ammonia is highly toxic and proper safeguards, including gas monitoring, are deemed critical to industrial health and safety programs.
