FIRST AID MEASURES First Aid Procedures Inhalation Move victim to fresh air. Call a Poison Centre or doctor if the victim feels unwell. Skin Contact Take off contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Wash gently and thoroughly with lukewarm, gently flowing water and non-abrasive soap for 5 minutes. Call a Poison Centre or doctor if the victim feels unwell. Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 15-20 minutes, while holding the eyelid(s) open. If irritation or pain persists, see a doctor. NEVER give anything by mouth if victim is rapidly losing consciousness, or is unconscious or convulsing. DO NOT INDUCE VOMITING. Have victim rinse mouth with water. Immediately call a Poison Centre or doctor. If exposed or concerned, see a doctor for medical advice. Eye Contact Ingestion First Aid Comments 5. FIRE FIGHTING MEASURES Flammable Properties FLAMMABLE SOLID. Suitable Extinguishing Small fire: Carbon dioxide, dry chemical powder, appropriate foam, water spray or fog. Media Large fire: Use flooding quantities of water spray or fog. Unsuitable Extinguishing Media None known. Specific Hazards Arising from the Chemical Gas or vapour may travel a considerable distance to a source of ignition and flash back to a leak or open container. In a fire, the following hazardous materials may be generated: very toxic carbon monoxide, carbon dioxide. Protective Equipment Use extreme caution. and Precautions for Firefighters should enter area wearing specialized protective equipment. (Bunker Gear will not Firefighters provide adequate protection.). 6. ACCIDENTAL RELEASE MEASURES Personal Precautions Use the Personal Protective Equipment recommended in Section 8 of this MSDS. Increase ventilation to area or move leaking container to a well-ventilated and secure area. Eliminate all ignition sources. Use grounded, explosion-proof equipment. Environmental If the spill is inside a building, prevent product from entering drains, ventilation systems and Precautions confined areas. Do not allow into any sewer, on the ground or into any waterway. Methods for Containment and Clean-up Stop or reduce leak if safe to do so. Store recovered product in suitable containers that are: tightly-covered. 7. HANDLING AND STORAGE Handling Storage Avoid repeated or prolonged skin contact with product or with contaminated equipment/surfaces. Only use where there is adequate ventilation. Avoid generating dusts. Avoid generating vapours or mists. Eliminate heat and ignition sources such as sparks, open flames, hot surfaces and static discharge. Post "No Smoking" signs. Store in an area that is: dry, well-ventilated, out of direct sunlight and away from heat and ignition sources, separate from incompatible materials (see Section 10: Stability and Reactivity). 8.
