3 HAZARDS IDENTIFICATIONPOTENTIAL HEALTH EFFECTSEye:Contact may cause mild eye irritation including stinging, watering and :Contact may cause mild irritation including redness and a burning sensation. Noharmful effects from skin absorption are (Breathing):No information available. Studies by other exposure routes suggest a low degreeof toxicity by inhalation. urea dust may cause mild irritation of the nose, throatand respiratory (Swallowing):No harmful effect report by ingestion. Swallowing may cause irritation of thedigestive andSymptoms:Effects of overexposure may include irritation of the nose, throat, respiratory anddigestive tract, nausea, vomiting, coughing, and transient :No carcinogenic effects in humans reported in the literature Organs:No data :Inadequate data available to evaluate the developmental effects of this Comments:May be harmful to livestock if ingested without adequate mixing.

4 If used for themanufacture of feeds for livestock, mix thoroughly by making a preblend withone of the ingredients, then adding and mixing the pre-blend with all otheringredients. Equivalent protein from urea should not exceed 1/3 of the protein inthe Conditions:None SAFETY data SHEETFEED urea 46%Page 4 of 9 Issue Date: April 20064. FIRST AID MEASURESEye:If irritation or redness develops, move victim away from exposure and into freshair. Flush eyes with clean water. If symptoms persist, seek medical :Remove contaminated shoes and clothing and cleanse affected area(s) thoroughlyby washing with mild soap and water. If irritation or redness develops andpersists, seek medical (Breathing):If respiratory symptoms develop, move victim away from source of exposure andinto fresh air.

5 If symptoms persist, seek medical attention. If victim is notbreathing, clear airway and immediately begin artificial respiration. If breathingdifficulties develop, oxygen should be administered by qualified personnel. Seekimmediate medical (Swallowing):First aid is not normally required; however, if swallowed and symptoms develop,seek medical to Physicians:No information Antidoteand EmergencyTreatment:In animals, the cold water-acetic acid treatment may be useful. The adult cow isgiven 19 - 38 liters cold water and liters of 5% acetic acid (vinegar) treatment limits absorption of ammonia from the rumen by diluting therumen contents and slowing the rate of hydrolysis of urea by decreasing rumenpH and temperature.

6 This treatment also promotes urine flow that, if maintainedby fluid therapy, may assure recovery from urea toxicity. Gaseous or fluid bloatshould be relieved before pumping water into the rumen.

Undergoes thermal decomposition at elevatedtemperatures to produce solid cyanuric acid and release toxic and combustiblegases (ammonia, carbon dioxide, and oxides of nitrogen).

Stay upwind and away from spill (dust hazard). Wear appropriate protective equipment, including respiratory protection, as conditions warrant (seeSection 8).

8 Prevent spilled MATERIAL from entering sewers, storm drains, other unauthorized treatment drainagesystems, and natural waterways. Notify appropriate federal, state, and local agencies as may be required (see Section 15). Minimize dust generation. Sweep up and package appropriately for HANDLING AND STORAGEH andling:The use of appropriate respiratory protection is advised when concentrationsexceed any established exposure limits (see Sections 2 and 8). Wash thoroughlyafter handling. Wash contaminated clothing or shoes. Use good personal used for the manufacture of feeds for livestock, mix thoroughly by making apre-blend with one of the ingredients, then adding and mixing the preblend withall other :Keep container(s) tightly closed.

9 Use and store this MATERIAL in cool, dry, wellventilated areas. Sore only in approved containers. Keep away from anyincompatible MATERIAL (see Section 10). Protect container(s) against EXPOSURE CONTROLS/PERSONAL PROTECTIONE ngineeringControls:If current ventilation practices are not adequate to maintain airborneconcentrations below the established exposure limits (see Section 2), additionalventilation or exhaust systems may be SAFETY data SHEETFEED urea 46%Page 6 of 9 Issue Date: April 2006 Personal Protective Equipment (PPE)Respiratory:A NIOSH approved air purifying respirator with a type 95 (R or P) particulatefilter may be used under conditions where airborne concentrations are expected toexceed exposure limits (see Section 2).

10 Protection provided by air purifyingrespirators is limited (see manufacturer's respirator selection guide). Use apositive pressure air supplied respirator if there is potential for uncontrolledrelease, exposure levels are not known, or any other circumstances where airpurifying respirators may not provide adequate protection. A respiratoryprotection program that meets OSHA's 29 CFR and ANSI must be followed if workplace conditions warrant a :The use of cloth or leather work gloves is advised to prevent skin contact,possible irritation and absorption (see glove manufacturer literature forinformation on permeability).Eye/Face:Approved eye protection to safeguard against potential eye contact, irritation, orinjury is PPE:A source of clean water should be available in the work area for flushing eyes andskin.
