Anhydrous ammonia is a nitrogen liberating fertilizer.
It is stored in liquid form in pressured tanks and is sprayed directly onto fields. Exposure to anhydrous ammonia can occur during this application or during connection of a tank to spraying equipment. The most severe burns result from direct contact with the liquid ammonia. Anhydrous ammonia is very water soluble and forms a strong alkaline solution which can produce severe burns of the skin, eyes or mucous membranes. First and second degree burns of the skin can result.
