UNUSUAL FIRE OR
EXPLOSION DATA: |
Aqueous
solutions of Urea- Ammonium Nitrate will not burn or support
combustion, but will decompose into noxious, poisonous gases
when exposed to the high temperatures of a fire. The solutions
may become explosive if combined with a flammable substance
and/or dried to a low percentage of water. |

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. |
EFFECTS OF
OVER EXPOSURE: |
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. |

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.

- 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.
Consult
DOT "Emergency Response Guidebook" - Guide 31.

Special Precautions and Comments
|
|
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.
