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.
Unusual Fire and Explosion Hazards: 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: Dust and micro particles may cause eye irritation.
Skin: Frequent or prolonged contact with dust may aggravate preexisting dermatitis and possibly promote an allergic
reaction.
Ingestion: Abdominal pain, nausea, vomiting and gastrointestinal irritation may result. (Urea is a protein to ruminants,
animals with the enzyme Urease in their digestive systems, but is moderately toxic to humans when ingested).
Inhalation: Excessive inhalation of the dust may cause sore throat, coughing and irritation of mucous membranes and
the respiratory tract.
Systemic or Other Effects: None known.
Carcinogenicity: NTP IARC Monographs OSHA Regulated
Urea No No No
Biuret No No No
Methylene diurea No No No
Emergency and First Aid Procedures
Eyes: Immediately flush with large amounts of water, including under the eyelids. If pain persists seek medical attention,
preferably an Ophthalmologist. Speed and thoroughness in rinsing eyes are important to avoid permanent injury.
Skin: Immediately remove contaminated clothing and shoes. Wash affected area with soap and flush with large
amounts of water. Seek medical attention if irritation develops.
Ingestion: Do not induce vomiting. If vomiting occurs, keep head below hips to help prevent aspiration. Get medical
attention immediately.
Inhalation: Remove to fresh air. If breathing has stopped, apply artificial respiration. Keep warm and at rest. Get
medical attention immediately.
Special Considerations: None.
SECTION VI - REACTIVITY DATA
Stability: Stable. Decomposes at about 135癈, just above its melting point. Can be made explosive when
dissolved in Nitric Acid, even without completely drying.
Conditions to Avoid: Avoid exposing containers to heat or flame. Keep separated from incompatible materials.
Formaldehyde may be formed and released if feed urea is dissolved in highly acidic solutions.
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: Shovel spilled material into containers for disposal. Do not
flush to surface water. Spilled chemical can be used as fertilizer (46-0-0). 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.
SECTION VIII - SPECIAL PROTECTION INFORMATION
Ventilation: Provide adequate general and local exhaust ventilation to avoid reaching occupational exposure limits,
particularly in a confined space area.
Respiratory Protection: Urea is water-soluble and will dissolve with mucosal membrane contact (lungs). Use NIOSH
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 dust may exceed occupational
exposure limits (15 mg/m3).
Protective Clothing: Urea is water-soluble and will dissolve with perspiration contact. Wearing of appropriate protective
clothing and gloves is suggested if epidermal sensitivity develops.
Eye Protection: Urea is water-soluble and will dissolve with mucosal membrane contact (eyes). Remove contact lenses
and wear safety glasses, chemical goggles or face shield where contact with dust or micro particles 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: None.
