With slight ammonia (pungent) odor. Reacts with sodium hypochlorite or calcium hypochlorite to form the explosive nitrogen trichloride. When heated, urea Prod.Name: TerraCair Urea Solution, AUS 32 Manufacturer: Terra Industries Inc. Supplier: GM of Canada - Oshawa HMCS ID: 1189736 SUC: 16 - General Use MATERIAL SAFETY DATA SHEET Revision: 17.May.2007 Effective: 17.May.2007 Print Date: 05.Apr.2010 Page: 2 of 6 3 HAZARDS IDENTIFICATION Hazards Overview: releases ammonia and when heated to decomposition it emits toxic fumes of nitrogen oxides (NOx), ammonia, and cyanuric acid. Use water to control fires involving urea solution if water is compatible with burning material. Urea solution itself is non flammable. Specific Hazards: Primary Routes of Entry: Skin contact/absorption, eye contact, and vapor inhalation. Specific Hazards (Routes Of Exposure): Exposure Routes Exposure Duration Observation Eye Contact Acute May cause irritation to eyes. Skin Contact Acute May cause irritation to skin. Medical Conditions Aggravated By Exposure: No test data available. Additional Health Hazard Data: Ammonia and carbon dioxide vapors may accumulate in a confined space. General Chronic Exposure: No test data available. 4 FIRST AID MEASURES First Aid By:: Inhalation If irritation develops move patient to fresh air and monitor. If cough or difficulty in breathing develops, evaluate for respiratory tract irritation. If trained to do so, administer supplemental oxygen if needed. If irritation, coughing, or difficulty in breathing persists the patient should be seen in a health care facility. Skin Contact If irritation occurs, flush exposed area with copious amounts of tepid water for at least 15 minutes followed by washing area thoroughly with soap and water. The patient should be seen in a health care facility if irritation or pain persists. Eye Contact Flush eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, excessive tearing, or light sensitivity persists, the patient should be seen in a health care facility. Ingestion If conscious, give the patient large quantities of water to drink and induce vomiting. Seek medical attention. 5 FIRE FIGHTING MEASURES Product Flammability: Urea solution is not flammable. Extinguishing Media: Use water to extinguish a fire involving urea solution if water is compatible with the burning material. Fire and Explosion Hazards: At elevated temperature, urea solution may decompose to form cyanuric acid, ammonia, biuret, and/or nitrogen oxides. Special Fire Fighting Procedures: Positive pressure self-contained breathing apparatus (SCBA) should be used when there is a potential for inhalation of vapors and/or fumes. Wear full fire fighting protective equipment that is appropriate for conditions. Runoff from fire control or dilution water may cause pollution. 6 ACCIDENTAL RELEASE MEASURES PRECAUTIONS IN CASE OF ACCIDENTAL RELEASE Personal Precautions: Keep unnecessary people away and isolate hazard area. Urea solution may be toxic to cattle (ruminants) when ingested if amount ingested is not controlled properly. Generally, a small spill is one that involves a single, small package (i.e. up to a 55 gallon drum), small cylinder, or a small (non- continuing) leak from a large container. Spilled urea solution may cause slippery conditions. Environmental Precautions: Prod.Name: TerraCair Urea Solution, AUS 32 Manufacturer: Terra Industries Inc.

SPILL OR LEAK PROCEDURES Recovery: Recover and use as fertilizer. If disposal of product or contaminated by-products is necessary, follow guidelines set forth by local, state, and federal environmental agencies. 7 HANDLING AND STORAGE HANDLING Safe Handling Procedures: Use proper personal protective equipment when working with or around urea solution. (See section 8). STORAGE Storage Conditions: No unusual storage precautions are necessary. 8 EXPOSURE CONTROLS/PERSONAL PROTECTION Engineering Measures: If necessary to enter an area that contains urea solution, monitor for ammonia and oxygen content. Oxygen levels should be maintained between 19.5% and 23.5%, if outside of this range use appropriate precautions. Adequate ventilation should be supplied. Safety shower and eyewash fountain or at least 5 gallons of accessible clean water should be provided in a urea solution storage/handling area.

If ammonia vapors are present, protect as follows: <25 ppm: No protection required. 25 to 35 ppm: Protection required if the daily TWA is exceeded. 35 to 50 ppm: Protection required if exposed for more than 15 minutes 50 to 250 ppm: Minimum of an air-purifying respirator equipped with ammonia canister(s) or cartridge (s). 250 to 300 ppm: Minimum of a full-face air-purifying respirator equipped with ammonia canister(s) or cartridge (s). >300 ppm: A fresh air supply system must be used (i.e. positive pressure self contained breathing apparatus) Hand Protection Chemically Impervious gloves should be worn. Eye Protection It is recommended that safety glasses or goggles be used and if there is a potential for splashing liquid, a face shield should be used in conjunction with the safety glasses or goggles. 9 PHYSICAL AND CHEMICAL PROPERTIES APPEARANCE Physical State: Liquid.
