Section IV 鈥? Fire and Explosion Hazard Data
Flash Point (Method Used): Not applicable Flammable Limits: LEL (Lower Explosive Limit) - N/A
UEL (Upper Explosive Limit) - N/A
Extinguishing Media: Suitable extinguishing agents. CO2, extinguishing powder, or water spray.
Special Fire Fighting Procedures: Fight larger fires with water or alcohol resistant foam. Firefighters should wear
protective equipment and self-contained breathing apparatus.
Unusual Fire and Explosion Hazards: During heating or in case of fire, poisonous gases are produced. Reaction with
incompatibles may pose an explosion hazard.
Section V 鈥? Reactivity Data
Unstable Conditions to Avoid: Protect from moisture and light. Hygroscopic.
Stability:
Stable X
Incompatibility (Materials to Avoid): Reacts with acids, alkalis, oxidizing agents, Lithium, and Bromine trifluoride. Urea
reacts with calcium hypochlorite or sodium hypochlorite to form the explosive nitrogen trichloride. It is incompatible with
sodium nitrite, gallium perchlorate, phosphorus pentachloride, titanium tetrachloride and chromyl chloride.
Hazardous Decomposition or Byproducts: When heated to above 801掳C it emits toxic fumes of chloride and sodium
oxide. Urea decomposes upon heating and can form products including ammonia, oxides of nitrogen, phosphorus oxides,
cyanuric acid, cyanic acid, biuret, and carbon dioxide.
May Occur Conditions to Avoid: Incompatible materials.

Section VI 鈥? Health Hazard Data
Inhalation? Yes Skin? Yes Ingestion? Yes
Route(s) of Entry:
Harmful. Urea can be harmful if swallowed or inhaled. Irritating to eyes, respiratory system, and
Health Hazards:
skin. Irritant to mucous membrane.
(Acute and Chronic)
Carcinogenicity: NTP? No IARC Monographs? No OSHA Regulated? No
(National Toxicology Program) (International Agency for Research in Cancer)
Signs and Symptoms of Exposure: Can cause irritation to the respiratory tract. Symptoms may include coughing and
shortness of breath. May be absorbed into the bloodstream with symptoms similar to ingestion. mucous membranes.
Irritating effect to eye. Ingestion of Urea can cause nausea, vomiting, and diarrhea. May also include headache, confusion
and electrolyte depletion.
Medical Conditions Generally Aggravated by Exposure: A study of 67 workers in an environment with high airborne
concentrations of Urea found a high incidence of protein metabolism disturbances, moderate emphysema, and chronic
weight loss. Supersensitive individuals with skin or eye problems, kidney impairment or asthmatic condition should have
physician's鈥? approval before exposure to Urea dust. The toxicity of phosphates is their ability to sequester calcium.
Chronic exposure of phosphates may sequester calcium and cause calcium phosphate deposits in the kidneys.
Ingestion: If swallowed, seek medical attention immediately.
Emergency /
First Aid
Inhalation: Supply fresh air or oxygen. Seek medical attention.
Procedures:
Eye Contact: Rinse opened eye for at least 15 minutes under running water. Seek medical attention.
Skin Contact: Wash with plenty of soap and water for at least 15 minutes. Seek medical attention.
Section VII 鈥? Precautions for Safe Handling and Use
Accidental Release Measures: Ventilate area of leak or spill. Wear suitable protective clothing. Wipe up with damp
sponge or mop. Remove contaminated clothing.
Waste Disposal Method: Dispose in accordance with all applicable federal, state, and local environmental regulations.
Handling and Storing: Keep container tightly closed. Protect from moisture. Suitable for any general chemical storage
area. Store away from incompatible materials.
Other Precautions: Prevent formation of dust. Ensure good ventilation / exhaustion at the workplace. Containers of this
material may be hazardous when empty since they retain product residues. Avoid prolonged or repeated exposure.
Section VIII 鈥? Control Measures
Respiratory Protection (Specify Type): None required where adequate ventilation conditions exist. If airborne
concentration is high, use an appropriate respirator or dust mask.
Local Exhaust: 50 鈥? 100 CFM Special: N/A
Ventilation:
Mechanical (General): N/A Other: N/A
Protective Gloves: Proper disposable gloves Eye Protection: Chemical resistant safety goggles
Other Protective Clothing or Equipment: Uniform, lab coat, or disposable lab wear.
Work / Hygienic Practices: Follow the usual precautionary measures for handling chemicals / powder. Keep away from
food and beverages. Immediately remove all soiled and contaminated clothing. Avoid contact with eyes, skin, and
clothing.
