Material Safety Data Sheet
SECTION IV - FIRE AND EXPLOSION HAZARD DATA
Flash Point: Not applicable Flammable Limits: Not applicable
Extinguishing Media: Not applicable
Special Fire Fighting Procedures: Firefighters should wear self-contained breathing apparatus and full protective
clothing if urea solution reaches decomposition temperature.
Unusual Fire and Explosion Hazards: Aqueous solutions of urea will not burn or support combustion but will
decompose into noxious, poisonous gas when exposed to the high temperatures of a fire.
SECTION V - HEALTH HAZARD DATA
Effects of Overexposure
Eyes: Dried Urea dust or solution may cause eye irritation.
Skin: Dried Urea dust or solution may irritate skin resulting in reddening of the skin and possible dermatitis.
Ingestion: Dried Urea dust or solution may cause abdominal pain, nausea, vomiting and gastrointestinal irritation. (Urea
is a protein to ruminants, animals with the enzyme Urease in their digestive systems, but is toxic to humans).
Inhalation: Excessive inhalation of dried Urea dust or atomized solution may cause sore throat, coughing and irritation
of mucous membranes and the respiratory tract.
Systemic or Other Effects: The smell of ammonia, in the vapor space above the liquid, may aggravate respiratory
conditions.
Carcinogenicity: NTP: No IARC Monographs: No OSHA Regulated: No
Emergency and First Aid Procedures
Eyes: Immediately flush with large amounts of water, including under the eyelids. Cool burned area with ice. Contact a
physician immediately, preferably an Ophthalmologist. Speed and thoroughness in rinsing eyes are important to avoid
permanent injury.
Skin: Immediately remove contaminated clothing and shoes. Flush chemical from affected area with large amounts of
water, then wash with soap and water. Seek medical attention if irritation develops.
Ingestion: Do not induce vomiting. If vomiting occurs, keep head below hips to help prevent aspiration. Get immediate
medical attention.
Inhalation: Remove to fresh air. If breathing has stopped, apply artificial respiration. Keep warm and at rest. Get
immediate medical attention.
Special Considerations: None.
SECTION VI - REACTIVITY DATA
Stability: Stable. Decomposes at about 135癈, just above its melting point.
Conditions to Avoid: Avoid exposing containers to heat or flame. Keep separated from incompatible materials.
Materials to Avoid (Incompatibility): Nitric Acid, gallium, perchlorate, strong oxidizing agents, caustics and alkalis.
Hazardous Decomposition Products: Ammonia and Nitrogen Oxides (Nitric Oxide and Nitrogen Dioxide).
Hazardous Polymerization: Will not occur.
SECTION VII - SPILL OR LEAK PROCEDURES
Steps to be taken in Case Material is Released or Spilled: Contain spills as much as possible. Do not flush to surface
water. Spilled chemical can be used as fertilizer (46% N). Follow applicable Federal, State and local reporting
requirements.
Waste Disposal Method: Dispose through a licensed waste disposal company. Follow federal, state and local
regulations. Contaminated dirt may be spread as a fertilizer.

Material Safety Data Sheet
SECTION VIII - SPECIAL PROTECTION INFORMATION
Ventilation: Provide adequate general and local exhaust ventilation to avoid exceeding occupational exposure limits,
particularly in a confined space area.
Respiratory Protection: Dried Urea residue is water-soluble and 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 of dried amide may exceed
occupational exposure limits (15 mg/m3, dust).
Protective Clothing: Aqueous solution at ambient temperature will not cause tissue damage. Wearing of canvas work
clothing is sufficient protection.
Eye Protection: Aqueous solution at ambient temperature will not damage eyes. Wear safety glasses or chemical
goggles where contact with liquid may occur.
Other Precautions Required: None.
SECTION IX - SPECIAL PRECAUTIONS
Precautions to be taken in handling and storage: Store in compliance with all Federal, State, and local regulations.
Store in a well ventilated area, 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 noxious fumes.
Other Precautions: Never combine with nitric acid.
