Section 4.  First Aid Measures

Eye contact                              :   Immediately flush eyes with water for at least 15 minutes, occasionally lifting and lowering the upper and lower eyelids.  Check for and remove any contact lenses.  Get medical attention if irritation occurs.

Skin Contact                            :   Wash skin thoroughly with soap and water or use recognized skin cleanser.  Get medical attention if irritation occurs.  Remove contaminated clothing and shoes.  Wash clothing before reuse.  Clean shoes thoroughly before reuse.

Inhalation                                 :   Move exposed person to fresh air. Keep person warm and at rest.  If not breathing, if breathing is irregular or if respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel.  If may be dangerous to the person providing aid to give mouth-to-mouth resuscitation.  Get medical attention if symptoms occur.  If unconscious, place in recovery position and get medical attention immediately.  Maintain an open airway.  Loosen tight clothing such as a collar, tie, belt or waistband.

Ingestion                                  :   Wash out mouth with water.  Remove dentures if any.  Move exposed person to fresh air.  Keep person warm and at rest.  If material has been swallowed and the exposed person is conscious, give small quantities of water to drink.  Stop if the exposed person feels sick as vomiting may be dangerous.  Do not induce vomiting unless directed to do so by medical personnel.  If vomiting occurs, the head should be kept low so that vomit does not enter the lungs.  Get medical attention.  Never give anything by mouth to an unconscious person.  If unconscious, place in recovery position and get medical attention immediately.  Maintain an open airway.  Loosen tight clothing such as a collar, tie, belt or waistband.

  Procedures                            :   material. Toxic gas and vapor (carbon monoxide, ammonia, nitrogen oxide) may be released by decomposition.

Other Fire/Explosion Hazards  :   Not combustible, but urea decomposes at > 133°C generating toxic NO_x fumes and ammonia gas.

Section 6.  Accidental release measures

Personal precautions               :   Immediately contact emergency personnel.  Keep unnecessary personnel away.  Use suitable protective equipment.

Environmental precautions      :   Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains and sewers.

Method of Cleaning up             :   Collect all spilled material and store in containers suitable for recycle or disposal.

Section 7.  Handling and storage

Handling                                  :   Avoid contact with eyes, skin and clothing.  Ensure that eyewash stations and safety showers are close to the workstation location.

Storage                                    :   Urea is extremely hygroscopic at relative humidity above approximately 70%.  Store in a cool and well-ventilated area.  Keep away from heat, sparks, and flame.  Keep containers closed.  Do not expose sealed containers to temperatures above 49°C.  Keep dry.

Section 8.  Exposure Controls, Personal Protection

Engineering Controls               :   Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their respective occupational exposure limits.  Ensure that eyewash stations and safety showers are close to the workstation location.

Personal Protection

Eyes                                         :   Use chemical safety goggles when there is potential for eye contact.

Skin                                         :   Cotton gloves and protective clothing should be used.

Respiratory                              :   A dust mask should be suitable for most applications.  Wear respiratory protection for dust/mist where ventilation is inadequate.

Other Precautions                    :   Locate safety shower and eyewash station close to chemical handling area.

Exposure limits                        :   OSHA PEL
