Reactivity Alerts
- Explosive
Air & Water Reactions
Water soluble. A significant amount of heat may be generated when water is added to the mixture.
Fire Hazard
Special Hazards of Combustion Products: Heating to decomposition yields oxides of nitrogen.
Behavior in Fire: Organic and oxidizable materials can sensitize DRY ammonium nitrate to readily explodable state; can detonate if heated under confinement with high pressure. (USCG, 1999)
Behavior in Fire: Organic and oxidizable materials can sensitize DRY ammonium nitrate to readily explodable state; can detonate if heated under confinement with high pressure. (USCG, 1999)
Health Hazard
INHALATION: Irritation of mucous membranes may result from exposure. EYES and SKIN: Irritation may result from exposure. INGESTION: Nausea, possible vomiting and diarrhea. Methemoglobinemia may occur, particularly in children under 1 year of age. (USCG, 1999)
Reactivity Profile
UREA, AMMONIUM NITRATE SOLUTION, (W/AQUA AMMONIA) is a basic solution. Reacts exothermically with acids. Can react with both oxidizing agents and reducing agents. May be subject to detonation if allowed to dry out.
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents
Use caution: Liquids with this reactive group classification have been known to react with the absorbents listed below. More info about absorbents, including situations to watch out for...

The
Response Recommendation fields
include isolation and evacuation distances, as well as recommendations for
firefighting, non-fire response, protective clothing, and first aid. The
information in CAMEO Chemicals comes from a variety of
data sources.
Isolation and Evacuation
No information available.
Firefighting
Fire Extinguishing Agents: Water (USCG, 1999)
Non-Fire Response
No information available.
Protective Clothing
Rubber gloves, safety glasses, clothes that minimize skin exposure. (USCG, 1999)
DuPont Tychem® Suit Fabrics
No information available.
First Aid
INHALATION: Evacuate to fresh air and give artificial resuscitation. Keep under observation for 24 hours as symptoms may be delayed.
EYES: Flush eyes with water for 15 minutes or until irritation subsides.
SKIN: Wash contaminated surface with soap and water. If irritation develops consult a physician.
INGESTION: Give milk and demulcents, induce emesis or perform gastric lavage: give fluids: observe for methemoglobinemia, particularly in infants. If needed, give methylene blue as a 1% solution intravenously, 1 to 2 mg/ kg; and if severe, consider exchange transfusion. (USCG, 1999)

Physical Properties

The
Physical Property fields
include properties such as vapor pressure and
boiling point, as well as explosive limits and
toxic exposure thresholds
The information in CAMEO Chemicals comes from a variety of
data sources.
Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
