Urea - Ammonium Nitrate Solution: Health Hazard Data
Carcinogenicity: NTP: NO
IARC Monographs: NO
OSHA Regulated: NO
Occupational Exposure Limits:
OSHA Permissible Exposure Limit (PEL): None established for Urea - Ammonium Nitrate.
ACGIH Short-term Exposure Limit (STEL): None established for Urea - Ammonium Nitrate.
NIOSH Immediately Dangerous to
Life and Health (IDLH): None established for Urea - Ammonium Nitrate.
Effects of Overexposure:
Acute:
Eyes: Dried salts or liquid may cause redness, pain and irritation to eye.
Skin: Dried salts or liquid may irritate skin resulting in reddening of the skin and possible dermatitis.
Frequent or prolonged contact may promote an allergic reaction.
Inhalation: Dried salts may be irritating to mucous membranes, respiratory tract, causing sore throat,
coughing, difficult breathing and severe lung congestion. Delayed reactions may result in
pulmonary edema and chemical pneumonitis.
Ingestion: Dried salts or liquid may cause gastric irritation, nausea, abdominal spasms, vomiting and
faintness. Large doses may cause systemic acidosis and methemoglobinemia.
Chronic:
None known for Ammonium Nitrate. None known for Urea.
Additional Medical and Toxicological Information:
Dried salt may aggravate preexisting dermatitis and lung conditions.

Urea - Ammonium Nitrate Solution: Emergency First Aid Procedures
Eye contact: Immediately flush with large amounts of water, including under the eyelids. If discomfort persists
contact a physician, preferably an Ophthalmologist. Speed and thoroughness in rinsing eyes are
important to avoid permanent injury.
Skin Contact: Immediately remove contaminated clothing and shoes. Wash the affected area with soap and
flush with large amounts of water. Get medical attention if discomfort persists.
Inhalation: Remove to fresh air. If breathing has stopped, apply artificial respiration. Keep warm and at rest.
Get immediate medical attention.
Ingestion: Do not induce vomiting. If vomiting occurs, keep head below hips to help prevent aspiration. Get
immediate medical attention. Treat for methemoglobinemia.
Urea - Ammonium Nitrate Solution: Suggested Protection
Eye Protection: UAN 32% is an aqueous salt solution and will dissolve with mucosal membrane contact (eyes).
Remove contact lenses and wear safety glasses, chemical goggles or face shield where contact
with liquid or dried salt may occur.
Skin Protection: UAN 32% is an aqueous salt solution and will dissolve with perspiration contact. Wearing of
appropriate protective clothing and gloves is suggested if epidermal sensitivity develops.
Inhalation: Dried salt or aerosol solution will dissolve with mucosal membrane contact (lungs). Use
approved respiratory protective equipment for cleaning large spills or upon entry into large tanks,
vessels, and other designated confined space areas or in any situations where airborne
concentrations may exceed occupational exposure limits. (15 mg/m3, dust)
Ventilation: Provide adequate general and local exhaust ventilation to attain occupational exposure limits,
particularly in a confined space area.
Urea - Ammonium Nitrate Solution: Spill or Leak
Spill Procedures: Remove sources of heat or ignition. Clean-up spill but do not flush to surface water.
Contaminated soil can be spread as if it were fertilizer.
Urea - Ammonium Nitrate Solution: Waste Disposal
Procedure: Dispose of through a licensed waste disposal company. Follow federal, state and local
regulations.

Urea - Ammonium Nitrate Solution: Special Precautions
Storage Precautions: Store away from incompatible materials or sources of heat and ignition. Empty containers may
contain residue and can be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind or
expose such containers to heat, flames, sparks or other sources of ignition; they may evolve
poisonous gas and cause injury or death.
Comment: Never heat a dried UAN solution, especially when confined.
Never combine with Nitric Acid.
