Safety Data Sheet MEG Energy Rail Loaded Dilbit SECTION 1. IDENTIFICATION Product Identifier Other Means of Identification Other Identification Product Family Recommended Use Manufacturer / Supplier MEG Energy Rail Loaded Dilbit Produced Crude Sour Crude, Sour Oil Crude Oil Refinery feedstock. MEG Energy, Christina Lake Regional Project P.O. Box 21008, Fort McMurray, Alberta, T9H 5B2 Emergency Phone No. Terrapure Environmental, 1-800-567-7455, (24 hr) CANUTEC, 1-613-996-6666, (24 hr) SECTION 2. HAZARDS IDENTIFICATION GHS Classification Flammable liquid - Category 1; Acute toxicity (Oral) - Category 2; Acute toxicity (Dermal) - Category 3; Acute toxicity (Inhalation) - Category 2; Skin corrosion/irritation - Category 2; Serious eye damage/eye irritation - Category 2A Other Hazards EMERGENCY OVERVIEW : FLAMMABLE LIQUID AND VAPOUR. Extremely flammable. May form flammable/explosive vapour-air mixtures. Electrostatic charges may be generated during handling. Electrostatic discharges may cause fire. CONTAINS HYDROGEN SULPHIDE. Product may contain hazardous quantities of dissolved hydrogen sulphide gas. H2S has a broad range of effects dependent on the airborne concentration and length of exposure: 0.02 ppm odor threshold, smell of rotten eggs; 10 ppm eye and respiratory tract irritation; 100 ppm coughing, headache, dizziness, nausea, eye irritation, loss of sense of smell in minutes; 200 ppm potential for pulmonary edema after >20-30 minutes; 500 ppm loss of consciousness after short exposures, potential for respiratory arrest; >1000 ppm immediate loss of consciousness, may lead rapidly to death, prompt cardiopulmonary resuscitation may be required. Do not depend on sense of smell for warning. H2S causes rapid olfactory fatigue (deadens sense of smell). There is no evidence that H2S will accumulate in the body tissue after repeated exposure. HIGHLY FLAMMABLE : Will be easily ignited by heat, sparks, or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along the ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors, or in sewers. Runoff to sewer may create fire or explosion hazard. General Hygiene Comments : Do NOT eat, drink or store food in work areas.

If the victim has difficulty breathing or tightness in the chest, is dizzy, vomiting, or unresponsive, administer oxygen with rescue breathing or CPR as required. If breathing has stopped, trained personnel should begin rescue breathing. Obtain medical attention immediately. Skin Contact Avoid direct contact. Wear chemical protective clothing if necessary. Take off contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Immediately wash gently and thoroughly with lukewarm, gently flowing water and mild soap for 15-20 minutes. Eye Contact Immediately rinse the contaminated eye(s) with lukewarm, gently flowing water for 15-20 minutes, while holding the eyelid(s) open. If eye irritation persists, get medical advice/attention. Ingestion Rinse mouth with water. Immediately call a Poison Centre or doctor. Do not induce vomiting. Most Important Symptoms and Effects, Acute and Delayed If inhaled: Can irritate the nose and throat. Symptoms may include headache, nausea, dizziness, drowsiness and confusion. If in eyes: May cause moderate to severe irritation. Symptoms include sore, red eyes, and tearing. Product Identifier: MEG Energy If swallowed: Rail Loaded Dilbit Date Preparation: Page 02 of 08 10, 2015 Smallofamounts can irritateJune the mouth, throat and stomach. Large amounts can cause severe and/or permanent organ damage, even death. May cause moderate to severe irritation. Symptoms include sore, red eyes, and tearing. If swallowed: Small amounts can irritate the mouth, throat and stomach. Large amounts can cause severe and/or permanent organ damage, even death. SECTION 5. FIRE-FIGHTING MEASURES Suitable Extinguishing Media Small fire: Carbon dioxide, dry chemical powder, appropriate foam, water spray or fog. Large fire: Water spray, fog or regular foam. Do not use straight streams. Move containers from fire area if you can do it without risk. Fire involving Tanks or Car/Trailer Loads: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. Specific Hazards Arising from the Chemical PRODUCT CONTAINS HYDROGEN SULPHIDE. May accumulate in hazardous amounts in low-lying areas especially inside confined spaces, resulting in a health hazard. May accumulate in hazardous amounts in low-lying areas especially inside confined spaces, resulting in a fire hazard. Special Protective Equipment and Precautions for Fire-fighters Fight fire from a safe distance or a protected location. For a massive fire, immediately evacuate the area and use unmanned hose holder or monitor nozzles. Chemical protective clothing (e.g. chemical splash suit) and positive pressure SCBA may be necessary. SECTION 6. ACCIDENTAL RELEASE MEASURES Personal Precautions, Protective Equipment, and Emergency Procedures Evacuate the area immediately. Isolate the hazard area. Keep out unnecessary and unprotected personnel. Evacuate downwind locations. Use the personal protective equipment recommended in Section 8 of this safety data sheet.
