What is it?

Aqua ammonia is a solution of ammonia gas and water and has a sharp, irritating odor.

How is it used?

Aqua ammonia is one of CALAMCO’s key fertilizer products. It is used as a source of nitrogen and as an ingredient in the manufacture of some specialty fertilizers.

Potential Hazards

Aqua ammonia is corrosive to copper, silver, aluminum, zinc and zinc alloys. It reacts with body moisture and burns skin, eye, mouth, throat, lung and stomach tissues on contact if inhaled or swallowed.

Although the smell of ammonia is unpleasant and sharp, it is generally tolerable up to 25 parts-per-million (ppm). Above this concentration, irritation of the eyes, nose and throat may begin. 25ppm is also the OSHA permissible exposure. Above 400ppm, skin burns and coughing occur.

Flammability / Explosion Risk

Aqua ammonia is not flammable or explosive. However, when exposed to fire or elevated temperatures above 600°F, it will decompose into hydrogen and nitrogen. Hydrogen is a highly flammable gas. In a confined area, hydrogen presents an explosive danger and nitrogen presents an asphyxiation danger.

Emergency Response Procedures

In the event of a spill of aqua ammonia, local authorities will assess the scene. The local fire department will attempt to contain the spilled material and prevent additional discharge. If there is a fire, water will be used to extinguish the blaze. Any spilled aqua ammonia will be diluted with water and mopped up or absorbed with an inert dry material and placed in an appropriate disposal container.
