UREA-AMMONIUM NITRATE SOLUTION (UAN)

SECTION 2: Hazards identification

No. 1272/2008 Classification of substance or mixture Urea-ammonium nitrate solution (UAN) is a mixture of aqueous solutions of ammonium nitrate and urea with the addition of corrosion inhibitor

Health hazards

The following aspects should be taken into account skin contact: may cause irritation and slight burns of the skin eye contact: may cause irritation and eye disorders ingestion: no toxic effects in small quantities but if used in large quantities may cause nausea, vomit, diarrhea, abdominal pains or even methemoglobinemia inhaling: toxicity is very low for exposures to small quantities; the exposures to high concentrations may cause respiratory tract irritation, headaches, dizziness, tingling etc thermal decomposition products: inhaling gases resulted from thermal decomposition may cause serious disorders of the respiratory system

Environmental hazards

Therefore accidental discharge of Urea-ammonium nitrate solution (UAN) may have a negative impact on environment by soil, flowing or phreatic water contamination

2.2 Label elements

Labeling according to CLP Regulation The mixture is not classified as hazardous according to the Regulation No.1272/2008/EC on classification, labeling and packaging. 2.3 Other dangers
