3. HAZARDS IDENTIFICATION

EMERGENCY OVERVIEWNot available.Potential Health EffectsEye:Causes eye irritation.Skin:Causes skin irritation.Ingestion:Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause cardiac disturbances. May cause disturbed blood electrolyte balance.Inhalation:Inhalation of dust causes irritation of the nose and throat, coughing and sneezing.Chronic:Prolonged or repeated exposure may cause adverse reproductive effects. Laboratory experiments have resulted in mutagenic effects.Prolonged exposure or exposure to high concentrations may cause eye damage.

4. FIRST AID MEASURES

Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.Skin:Get medical aid. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.Wash clothing before reuse.Ingestion:Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.Inhalation:Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.Notes to Physician:Treat symptomatically and supportively. Weak acids such as acetic acid and propionic acid can be used as chemical antidotes, demulcents and stimulants.

5. FIRE FIGHTING MEASURES

General Information:During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Wear appropriate protective clothing to prevent contact with skin and eyes. Wear a self-contained breathing apparatus (SCBA) to prevent contact with thermal decomposition products.Extinguishing Media:Substance is noncombustible; use agent most appropriate to extinguish surrounding fire. Use water spray, dry chemical, carbon dioxide, or appropriate foam.

6. ACCIDENTAL RELEASE MEASURES

General Information:

Use proper personal protective equipment as indicated in Section 8.Spills/Leaks:Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty conditions.Provide ventilation.

7. HANDLING AND STORAGE

Handling:Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid breathing dust, vapor, mist, or gas. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.Storage:Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.

8. EXPOSURE CONTROLS, PERSONAL PROTECTION Engineering Controls:Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low.Exposure Limits CAS# 57-13-6: Russia: 10 mg/m3 TWA Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.Skin:Wear appropriate protective gloves to prevent skin exposure.Clothing:Wear appropriate protective clothing to prevent skin exposure.Respirators:A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant respirator use

11. TOXICOLOGICAL INFORMATION RTECS#:CAS# 57-13-6: YR6250000 LD50/LC50:CAS# 57-13-6: Oral, mouse: LD50 = 11 gm/kg; Oral, rat: LD50 = 8471 mg/kg.Carcinogenicity:Urea - Not listed by ACGIH, IARC, or NTP.Other:See actual entry in RTECS for complete information.

12. ECOLOGICAL INFORMATION Ecotoxicity:Bacteria: Phytobacterium phosphoreum: EC50 = 23914 mg/L; 5 min; Microtox testIf released to water, urea can degrade readily through biotic hydrolysis as demonstrated by various screening studies. The presence of naturally-occurring phytoplankton increases the degradation rate because phytoplankton use urea as a nitrogen source and because urea is decomposed by phytoplankton photosynthesis. In phytoplankton-rich waters, degradation occurs much faster in sunlight than in the dark. Abiotic hydrolysis of urea occurs very slowly in relation to biotic hydrolysis.
