Granular urea is received from ammonia and carbon dioxide. Urea is used in an industry as raw materials at manufacturing of pitches, glues, etc., for use in agriculture as mineral nitrogen fertilizer. Urea can be utilized in animal husbandry as fodder additive.
Urea is non-combustible, fire-and is explosion-proof under normal conditions. As regards to its influence on organism, it falls into 3-rd class of hazardous substances. Urea is packed in paper bitumized of laminated bags, polyethylene bags, woven polymeric laminated bags woven polymeric bags with inserts, and also in soft specialized containers as MKR-1, OS. Granular urea is stored in closed store rooms protecting the product from rainfall. At storage of product in bulk its mixture with other fertilizers is not permitted. It is permitted to store granular urea containers and transport packages fastened by synthetic film on open areas.
