Petroleum Distillate (mineral oil) 64742-47-8 55 Mild eye irritant, dizziness, nausea due to vapors (Sec. VI) The specific chemical identity of this material is being withheld as a trade secret. It will be provided to a treating health professional in accordance with 29 CFR Part 1910, 1200 (i) in the event of medical emergency. III. PHYSICAL DATA Boiling Point (ΕF): 424 - 460° F Specific Gravity (H2O=1): 0.97 Vapor Pressure (mm. Hg): ND Melting Point: ND Vapor Density (Air = 1): ND Evaporation Rate (Butyl Acetate = 1): ND Solubility in Water: ND pH: 6.9 Density (at 20Ε C): 8.1 lbs./gal.

Appearance/Odor

Off-white viscous liquid with mild very slight petroleum-like odor IV. FIRE AND EXPLOSION DATA Flash Point: >185° F (closed cup) Flammable Limits LEL ND UEL ND Special Fire Fighting Procedures: Water fog or spray may be used to cool containers. Avoid using water on product. Product becomes extremely slippery when mixed with water. Unusual Fire and Explosion Hazards: None Extinguishing Media: CO2, dry chemical, foam. V. REACTIVITY Stability: Stable. Hazardous Polymerization: Will not occur. Incompatibility: Strong oxidizing agents. Hazardous Decomposition Products: Thermal decomposition may produce CO2, and, possibly, CO. NA = Not Applicable ND = Not Determined Date Prepared August 30, 2001 77 of 78 Doc #: 4160-90 VI. HEALTH HAZARD INFORMATION Routes of Exposure and Effects: Eyes: Slight to moderate eye irritant. Skin: Prolonged or repeated skin contact tends to remove skin oils possibly leading to irritation and dermatitis. Inhalation: Vapors unlikely except at high temperatures. High vapor concentrations may cause mild mucous membrane irritation, headache, dizziness, nausea or unconsciousness in extreme cases. Ingestion: May cause indigestion. May have laxative affect due to mineral oil if ingested in larger amounts. Permissible Exposure Limits: OSHA TWA ACGIH TLV MFRS RECOMMENDED (for air contaminants) 5 mg/m3 ND 400 ppm (for mineral oil mist) Carcinogenicity: Not listed by NTP, IARC or OSHA.

Other Health Effects

A component has caused kidney injury in male rats only. No comparable hazard for injury is known in humans. Acute Oral LD5O: ND Acute Dermal LD5O: ND Aquatic Toxicology LC5O: ND Emergency and First Aid Procedures: Eyes: Flush with clear water for 15 minutes or until irritation stops. Seek medical attention if irritation continues. Skin: Wash with soap and water. Seek medical attention if irritation continues. Inhalation: Remove from exposure, give oxygen if symptoms are severe. Ingestion: Give two glasses of water and induce vomiting if subject is conscious. Seek medical attention if illness or adverse symptoms develop. VII. HANDLING AND USE PRECAUTIONS Steps to be Taken if Material is Released or Spilled: Contain spill and absorb with inert material such as sand or earth. Clean up area immediately. Flush area with large volumes of water after removing absorbent to thoroughly remove remaining product. Do not allow product, or its solutions, to enter waterways. Waste Disposal Methods: Product should be disposed of in accordance with applicable local, state and federal laws. Handling and Storage Precautions: Avoid high temperatures and open storage systems to minimize vapors. Do not reuse containers. Empty containers should be returned to a drum reconditioner or disposed of in an environmentally safe manner. Launder contaminated clothing before reuse. VIII. INDUSTRIAL HYGIENE CONTROL MEASURES Ventilation Requirements: Mechanical ventilation recommended for enclosed work spaces. Respirator: Normally not needed at ambient work temperatures. Where necessary use NIOSH/MSHA respirator approved for use with organic vapors. Eye Protection: Use splash goggles or face shield when eye contact may occur. Gloves: Use chemical resistant gloves, if needed, to avoid prolonged contact with skin. Other Protective Clothing or Equipment: Use chemical resistant clothing, if needed, to avoid contaminating regular clothing which would result in prolonged or repeated skin contact. IX. SPECIAL PRECAUTIONS Caution: Product becomes very slippery when mixed with water. DEPARTMENT OF TRANSPORTATION HAZARDOUS MATERIAL INFORMATION Shipping Name: Petroleum products, N.O.S.

FNFN would like to thank Fortis for their efforts in engaging with us, ranging from providing information on the proposed development, to offering to include FNFN in employment and archeological work. We understand that Fortis wishes to create a new crossing using the technique of horizontal directional drilling and that this option is the most cost effective, and poses the least environmental risk, of those being considered. Because of this, and as a result of FortisBC’s ongoing engagement with us, FNFN supports this option and has no objection to the project as currently proposed. However, FNFN is very concerned about the safety of our lands and waters in the face of development in our traditional territory, and will not support the option of installing an aerial crossing due to the greater environmental impact expected from this technique. If you have any questions, or wish to discuss this project further, please contact myself or Cynthia Burke at 250- 774-6313 or via email alexis.jorgensen@fnnation.ca, or cynthia.burke@fnnation.ca Sincerely, Alexis Jorgensen Environmental Technician Fort Nelson First Nation Lands Department
