4. FIRST-AID MEASURES

General: No action shall be taken involving any personal risk or without suitable training. Ingestion: If swallowed, do NOT induce vomiting. Give a glass of water. Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration using a barrier device. If breathing is difficult, give oxygen. Get medical attention. Skin Contact: Wash contaminated clothing before reuse. In case of contact, immediately flush skin with plenty of soap and water for at least 15 minutes. Get medical attention. Eye Contact: In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Most important symptoms/effects, acute and delayed Symptoms: No data available. Hazards: No data available. Indication of immediate medical attention and special treatment needed Treatment: Treatment is symptomatic and supportive.

5. FIRE-FIGHTING MEASURES

General Fire Hazards: Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations. Use standard firefighting procedures and consider the hazards of other involved materials. Suitable (and unsuitable) extinguishing media Suitable extinguishing media: Water spray Carbon dioxide Foam. Unsuitable extinguishing media: Do not use water jet as an extinguisher, as this will spread the fire. Specific hazards arising from the chemical: In case of fire, carbon monoxide and carbon dioxide may be formed. Acute overexposure to the products of combustion may result in irritation of the respiratory tract. Measurements at temperatures above 150°C in presence of air (oxygen) have shown that small amounts of formaldehyde are formed due to oxidative degradation. Special protective equipment and precautions for firefighters Special fire-fighting procedures: When using do not smoke. Do not empty into drains. Special protective equipment for firefighters: Combustible This product or a component thereof can flow along surfaces to reach a distant ignition source and flash back. Firefighters must wear NIOSH/MSHA approved positive pressure self-contained breathing apparatus with full face mask and full protective clothing.

6. ACCIDENTAL RELEASE MEASURES

Personal precautions, protective equipment and emergency procedures:Product releases methanol during application and curing. Avoid contact with eyes, skin, and clothing. Use only in well-ventilated areas. Avoid inhalation of vapors and spray mists. Keep container closed. Keep out of reach of children. See Section 8 of the SDS for Personal Protective Equipment. Methods and material for containment and cleaning up: Wear proper protective equipment as specified in the protective equipment section. Wipe, scrape, or soak up in an inert material and put in a container intended for flammable materials for disposal. Warn other workers of spill. Keep unauthorized personnel away. Environmental Precautions: Do not allow runoff to sewer, waterway, or ground.

7. HANDLING AND STORAGE

Precautions for Safe Handling: Sensitivity to static discharge is expected; material has a flash point below 200°F. Do not get in eyes, on skin, on clothing. Do not taste or swallow. Use only in wellventilated areas. See Section 8 of the SDS for Personal Protective Equipment. Conditions for Safe Storage, Including Any Incompatibilities: Keep container tightly closed. Recommended storage in original container below 30°C (85°F).
